| 1 | Waste production in aquaculture:Sources,components and managements in different culture systems显示文摘The intensification of aquaculture has emerged as a viable alternative for increasing aquaculture production due to competition that arose from the use of natural resources,such as land and water,by other production and developmental sectors.However,intensification demands increased inputs,such as fish and feed per unit culture area and,therefore,increased waste generation from the aquaculture production systems.The impact of waste products from aquaculture has increased public concern and threatens the sustainability of aquaculture practices.The need for increasing the production of aquaculture products cannot be overemphasized and,therefore,there is a need to develop culture systems that will increase fish production with efficient waste management in order to limit environmental degradation resulting from aquaculture wastes and ensure its sustainability.This paper reviewed various aspects of waste production from aquaculture,their sources,components,and methods of management,in different culture systems,primarily discussing waste production from feed,chemicals,and pathogens.We aimed to establish the sources of wastes,their contents,and potential harms to both the fish culture and the environment.Suggestions for managing wastes in different culture systems were made to ensure an improved and sustainable aquaculture production. | Akeem Babatunde Dauda Abdullateef Ajadi Adenike Susan Tola-Fabunmi Ayoola Olusegun Akinwole | 2019 | Aquaculture and Fisheries2019，4，3： | 19 |
| 2 | Natural and artificial polyploids in aquaculture显示文摘Genome polyploidy has been revealed to result in evolutionary advantages and novelties,and therefore,polyploid aquatic animals may possess excellent traits of economic interest including rapid growth,extensive adaptability and disease resistance.For this reason,numerous species of natural polyploid fishes,such as common carp,gibel carp,crucian carp,salmon,and sturgeon,were chosen as important target species for aquaculture.Many artificial polyploids have been commercially utilized for aquaculture and most of them were created from natural polyploid fishes of the Cyprinidae and Salmonidae.Thanks to the easy mass production and better economic traits in growth and flesh quality,the synthetized autopolyploids or allopolyploids from natural polyploid species in cyprinid fishes have been extensively applied to aquaculture throughout China.This review outlines polyploidy advantages and innovative opportunities,lists natural polyploid species used in aquaculture,and summarizes artificial polyploids that have been induced or synthetized,and used in aquaculture.Moreover,some main research trends on polyploid utilization and ploidy manipulation of aquaculture animals are also introduced and discussed in the review. | Li Zhou Jianfang Gui | 2017 | Aquaculture and Fisheries2017，2，3： | 16 |
| 3 | Effect of the number of freeze-thaw cycles number on the quality of Pacific white shrimp (Litopenaeus vannamei): An emphasis on moisture migration and microstructure by LF-NMR and SEM显示文摘The objective of this study was to evaluate the effects of the number of freeze-thaw(F-T)cycles on moisture migration,protein degradation,microstructure and quality in Litopenaeus vannamei.The quality of samples with different F-T cycles were determined by low-field nuclear magnetic resonance(LF-NMR),magnetic resonance imaging(MRI)and scanning electron microscopy(SEM),combined with sodium dodecyl sulphate polyacrylamide gel electrophoresis(SDS-PAGE),texture properties analysis(TPA),color difference,polyphenol oxidase(PPO)activity,total volatile basic nitrogen(TVB-N),total viable count(TVC),and sensory evaluation.The results showed that F-T cycles caused a significantly increase in transverse relaxation time in T22 and T23 and a decreased brightness of pseudo-color diagram after 4 F-T cycles,indicating that water mobility increased as immobilized water was shifted to free water.The texture of samples declined as well,especially after 4 F-T cycles.The rapid growth of PPO activity caused a decrease in brightness(L*)and an increase in redness(a∗)after 3 F-T cycles.The increase of TVB-N,TVC,and sensory score explained the changes in shrimp quality which became obvious after 3 F-T cycles and unacceptable after 6 cycles.Meanwhile,fewer than 4 F-T cycles accelerated protein aggregation,while denaturation occurred after 4 cycles.Therefore,repeated F-T cycles could accelerate the changes of protein,microstructure,water distribution,and quality deterioration especially after 3 F-T cycles,with a threshold was 6 F-T cycles. | Weiqing Lan Xiaoyu Hu Xiaohong Sun Xi Zhang Jing Xie | 2020 | Aquaculture and Fisheries2020，5，4： | 15 |
| 4 | Molecular basis of pathogenesis of emerging viruses infecting aquatic animals显示文摘Aquatic vertebrates are very abundant in the world,and they are of tremendous importance in providing global food security and nutrition.However,emergent and resurgent viruses,such as ranavirus(e.g.,Rana grylio virus,RGV and Andriasd avidianus ranavirus,ADRV),herpesvirus(e.g.,Carassius carassius herpesvirus,CaHV),reovirus(e.g.,grass carp reovirus 109,GCRV-109,Scophthal musmaximus reovirus,SMReV and Micropterus salmoides reovirus,MsReV),and rhabdovirus(e.g.,Siniper cachuatsi rhabdovirus,SCRV and Scophthal musmaximus rhabdovirus,SMRV)can cause severe diseases in aquaculture animals and wild lower vertebrates,such as frogs,giant salamanders,fish,and so on.Here,we will briefly describe the symptoms produced by the aforementioned viruses and the molecular basis of the virus ehost interactions.This manuscript aims to provide an overview of viral diseases in lower vertebrates with an emphasis on visible symptomatic manifestations and pathogenesis. | Lang Gui V.Gregory Chinchar Qiya Zhang | 2018 | Aquaculture and Fisheries2018，3，1： | 12 |
| 5 | Antibacterial mechanism of Ginkgo biloba leaf extract when applied to Shewanella putrefaciens and Saprophytic staphylococcus显示文摘The antimicrobial mechanism of Ginkgo biloba leaf extracts(GBLE)when applied to predominant spoilage bacteria(Shewanella putrefaciens and Saprophytic staphylococcus)on refrigerated pomfret and minimal inhibitory concentrations(MICs)were measured by the plate counting method.GBLE at MIC and 2MIC were prepared in tryptic soy broth(TSB)medium and equivalent amounts of sterile distilled water were used in place of GBLE as a control group.The impact of GBLE on the growth of bacteria,the permeability of cell membrane,and cell wall were also investigated by growth curve of bacteria,alkaline phosphates activity(AKP),and electrical conductivity.A scanning electron microscope(SEM)was used to study the effects of GBLE on the cellular structure of S.putrefaciens and S.staphylococcus.The results showed that the MICs of GBLE when applied to S.putrefaciens and S.staphylococcus were 100 mg/mL,the inhibitory rates of MIC and 2MIC concentrations of GBLE when applied to S.putrefaciens were 36.11%and 100%,while 27.78%and 62.22%for S.staphylococcus.Meanwhile,GBLE inhibited the growth of S.putrefaciens and S.staphylococcus until the number of cells at 2MIC values decreased to 0 and 4.29 log CFU/mL,respectively,after 24 h.The electrical conductivity of bacteria increased with GBLE treatment,which was followed by an increased leakage of AKP.The SEM revealed that the structure of bacterial cells was destroyed and the bacteria began to be adhere to each other.The inhibition effect of GBLE when applied to S.putrefaciens and S.staphylococcus was related to the damage of cell membrane and cell wall.It was also revealed that GBLE damages the morphology of bacteria and had stronger effects on the cell membrane of S.putrefaciens than that of S.staphylococcus. | Nannan Zhang Weiqing Lan Qian Wang Xiaohong Sun Jing Xie | 2018 | Aquaculture and Fisheries2018，3，4： | 11 |
| 6 | The biological content of ballast water in China:A review显示文摘The introduction of species through the release of ballast water has become a major threats to marine biodiversity and ecosystem function worldwide.China is one of the top trading countries,yet little is known about exotic species in the ballast water of ships coming to its ports.Here,we review the biological surveys of ballast water from major Chinese ports.These surveys reveal that 40 species of nonindigenous phytoplankton that,belong to 25 genera and five phyla,have been observed in ballast water.The dominant species are diatoms and dinoflagellates.There were 17 red-tide causing species observed,five of which are noxious algae.Seventeen species of non-indigenous zooplankton have been reported,most of them(11)copepods.There were also 22 species of pathogenic bacteria recorded,including Vibrio alginolyticus,V.carchariae,V.parahaemolyticus,and V.vulnificus.These studies show that species introduction through ballast water potentially a serious threat to the ecology and human health in China.More research,including collaboration with the international community,is urgently needed to address this problem. | Huixian Wu Chen Chen Qiong Wang Junda Lin Junzeng Xue | 2017 | Aquaculture and Fisheries2017，2，6： | 11 |
| 7 | Effect of quercetin-containing preservatives and modified atmospheric packaging on the production of biogenic amines in Pacific white shrimp(Litopenaeus vannamei)显示文摘To investigate the productions of biogenic amines(BAs)in Pacific white shrimp treated by compound preservatives(P,0.05 g/L quercetin,0.025 g/L 4-hexylresorcinol,and 0.025 g/L cinnamic acid)in combination with modified atmosphere packaging(M,80% CO_(2)/10% O_(2)/10% N_(2)),four groups of samples treated with or without preservatives and alone or in combination with modified atmosphere packaging(A,A+P,M,M+P)during storage at 4℃for 12 days were analyzed.Most BAs increased in all samples,especially,putrescine and cadaverine.MAP inhibited the increase of most BAs(except for tyramine)and psychrotrophic bacterial counts.The inhibitory effect of the compound preservatives on bacterial growth and BAs was limited in aerobically-and MAP-stored samples,but they retarded the production of tyramine,which accumulated more rapidly in MAP.Lowest total BAs and bacterial counts were found in sample M+P(78.3 mg/kg and 5.82 log cfu/g,day 12),indicating that the combined treatment of the preservatives and MAP could reduce the risk of disorders caused by BAs. | Yunfang Qian Shengping Yang Jing-xin Ye Jing Xie | 2018 | Aquaculture and Fisheries2018，3，6： | 7 |
| 8 | Natural versus synthetic anesthetic for transport of live fish:A review显示文摘An increased awareness of food safety and quality has led to an increased demand for live edible fish.This product requires effective and efficient handling technology and transport to ensure a low mortality rate,but live fish transport has not yet met this criteria.Anesthetized fish can be transported in larger quantities without being stressed during transfer,maintaining a higher quality.This paper explored synthetic and natural anesthetics derived from terrestrial and aquatic resources.This review of the different types,sources,and applications of natural and synthetic anesthetics was used to investigate the potential of seaweed as an anesthetic.In addition,advantages and disadvantages of anesthetics and the potential of seaweed as a prospect of anesthetic are discussed. | Ninik Purbosari Endang Warsiki Khaswar Syamsu Joko Santoso | 2019 | Aquaculture and Fisheries2019，4，4： | 6 |
| 9 | Methane and nitrous oxide emissions in rice-crab culture systems of northeast China显示文摘Rice-crab integrated ecosystem has been confirmed to improve the ecological environment and brought greater economic benefits.In order to know greenhouse gases methane(CH_(4))and nitrous oxide(N_(2)O)emissions in ricecrab system,they were quantified from a flooding rice field in northeast China,as affected by integrated ricecrab cultivation.Three treatments with three replications each were given:(1)RC1-rice with crab(megalopa),(2)RC2-rice with crab(juvenile),(3)RM-rice only.Seasonal CH_(4) and N_(2)O fluxes were measured by closed chamber method.Compared with RM treatment,RC1 and RC2 treatments greatly enhanced the cumulative seasonal CH_(4) emissions(by 36.8%and 29.2%,respectively),and reduced the cumulative seasonal N_(2)O emissions(by 28.2%and 19.7%,respectively).Across treatments,CH_(4) represented over 97%of total global warming potential(GWP)and as a result,RC1 and RC2 treatments significantly increased the GWP than RM treatment.Although the GWP was highest in RC1 treatment,it provided highest rice yield(8780 kg/ha)and net ecosystem economic budget(NEEB,23,159 Yuan/ha)over RM(7668 kg/ha,15,130 Yuan/ha)and RC2(8042 kg/ha,18,713 Yuan/ha)treatments.To summarize,cultivation of megalopa in rice field is a better strategy to optimize the economic and environmental benefits in northeast China. | Ang Wang Xuzhou Ma Jing Xu Weiqun Lu | 2019 | Aquaculture and Fisheries2019，4，4： | 6 |
| 10 | Hic74,a novel alanine and glycine rich matrix protein related to nacreous layer formation in the mollusc Hyriopsis cumingii显示文摘Organic matrix proteins play an important role in the biomineralization of mollusc shells.We have identified and characterized a novel matrix protein,namely hic74,isolated from the mantle of the freshwater mussel Hyriopsis cumingii.The hic74 gene encodes a 850 amino acid protein that is rich in alanine(ala,30.8%),glycine(gly,25.8%)and serine(ser,10.6%),with ala mainly existing in poly-ala forms within the ala/gly-rich regions.Quantitative PCR expression analysis demonstrated that hic74 was specifically amplified from the mantle and in situ hybridization showed a strong signal in the epithelial cells in the pallial region of the mantle.Lower levels of expression were detected during the early stages of pearl sac formation but increased and remained constant during nacreous layer formation suggesting that hic74 might be involved in this process. | Xiaojun Liu Can Jin Leiming Wu Shaojian Dong Shimei Zeng Jiale Li | 2017 | Aquaculture and Fisheries2017，2，3： | 6 |
| 11 | The potential of Clostridium autoethanogenum,a new single cell protein,in substituting fish meal in the diet of largemouth bass(Micropterus salmoides):Growth,feed utilization and intestinal histology显示文摘This study investigated the effects of replacing fishmeal with Clostridium autoethanogenum protein(CAP)on growth,feed utilization and intestinal histology of largemouth bass(Micropterus salmoides).The control diet contained 350 g/kg fishmeal,and then dietary fishmeal was decreased to 300 g/kg,250 g/kg,200 g/kg,150 g/kg and 100 g/kg by CAP inclusion,respectively(FM-30,FM-25,FM-20,FM-15,FM-10).The largemouth bass(110.0±1.0 g)were fed one of the six diets for 8 weeks.The groups of FM-30,FM-25 and FM-20 showed the similar weight gain(WG)and feed conversion ratio(FCR)to the control(P>0.05),while the WG of FM-10 group was decreased by 15.9%,and FCR increased by 0.12 when compared to the control(P<0.05).FM-15 and FM-10 groups had lower protein retention,lower villus height in intestine and higher serum malondialdehyde content than the control(P<0.05).The protease activity in FM-20,FM-15 and FM-10 groups was lower than that in the control(P<0.05),but no difference was observed in crude protein digestibility among groups(P>0.05).In conclusion,CAP could replace 150 g/kg fishmeal in diet(350 g/kg fishmeal)without adverse effects on growth,feed utilization and intestinal histology of largemouth bass. | Pinxian Yang Xiaoqin Li Bowen Song Ming He Chaoyi Wu Xiangjun Leng | 2023 | Aquaculture and Fisheries2023，8，1： | 6 |
| 12 | Comparison of nitrate-removal efficiency and bacterial properties using PCL and PHBV polymers as a carbon source to treat aquaculture water显示文摘Nitrate(NO_(3)^(−))accumulation in recirculating aquaculture systems(RASs)with high stocking densities presents a problem for reared animals and the environment.The use of a biodegradable polymer as organic carbon for heterotrophic denitrification exhibits good performance for NO_(3)^(−)removal from wastewater.A comparison of NO_(3)^(−)–N removal efficiency and bacterial properties using polycaprolactone(PCL)and poly(3-hydroxybutyrateco-3-hydroxyvalerate)(PHBV)as carbon sources to treat aquaculture water was conducted for a 102-day period.The results indicated that the NO_(3)^(−)–N removal rates of 0.27±0.07 and 0.19±0.05 g/L per day,respectively,could be achieved with influent concentrations ranging from 81.1 to 132.75 mg/L and a flow rate of 1 L/h.The removal of NO_(3)^(−)–N versus consumed PCL(1:1 w/w)was significantly higher than that versus consumed PHBV(0.3:1 w/w)(P<0.05).The concentrations of effluent nitrite-nitrogen and total ammonium nitrogen were maintained at an acceptable level.The bacterial community structures between the two types of reactors varied significantly.Acidovorax and Denitratisoma were the top two genera of the bacterial community in the biofilm in the PCL beads with a dominance of 26.83%and 6.67%,respectively.In the PHBV beads,Acidovorax at 17.95%and Bdellovibrio at 6.37%were the top two genera.The PCL-denitrification reactor developed in this study showed better potential than the PHBV-denitrification reactor in removing NO_(3)^(−)from aquaculture water. | Guozhi Luo Zhiwei Hou Luqi Tian Hongxin Tan | 2020 | Aquaculture and Fisheries2020，5，2： | 5 |
| 13 | Sensory and chemical assessment of silver pomfret (Pampus argenteus) treated with Ginkgo biloba leaf extract treatment during storage in ice显示文摘This study investigated the physical(L*,a*,b*,texture profile analyses,pH),chemical(TVB-N,K value and TBA),microbiological,amino acid content,and flavor effects that Gingko biloba leaf extract(GBLE)had on silver pomfret(Pampus argenteus)stored at 4±1C in ice for 18 days.Fresh pomfret samples were obtained directly from the local fish market and transported to the laboratory with ice immediately.After being gutted,washed,filleted and trimmed in a water-ice mixture,samples were treated with different concentrations of GBLE(0.0 mg/mL,2.5 mg/mL,5.0 mg/mL,10.0 mg/mL)and packaged in Polyethylene bag,then stored in a refrigerator at 4±1C with ice.The results show that the shelf-life of untreated(0.0 mg/mL)pomfret samples was 8e9 days compared to 14e15 days for the GBLE1(2.5 mg/mL)treated group.The assessment results showed that different concentrations of GBLE had variable effects on preserving the texture parameters of acceptability limit,inhibit lipid oxidation,protein degradation,and microorganism growth.2.5 mg/mL of GBLE was the best for the preservation of pomfret during storage in ice.Therefore,there is potential use for GBLE as a preservative to extend the shelf-life of pomfret during chilled storage in ice. | Weiqing Lan Xu Che Qiaoling Xu Ting Wang Ruoyuan Du Jing Xie Min Hou Han Lei | 2018 | Aquaculture and Fisheries2018，3，1： | 5 |
| 14 | Comparing salinities of 0, 10 and 20 in biofloc genetically improved farmed tilapia (Oreochromis niloticus) production systems显示文摘A 150 days(150-d)experiment was carried out to investigate the production efficiency,inorganic nitrogen syndrome and bacteria community of indoor biofloc technology(BFT)systems used to rear genetically improved farmed tilapia(Oreochromis niloticus)under 0(S-0),10(S-10),and 20 salinities(S20).The start-up period for BFT was 50,60 and 80 d for S-0,S-10 and S-20 groups,respectively.At steady state,the total ammonium nitrogen(NH4þ-N)and nitrite nitrogen(NO2-N)were lower than 3.0 mg/L and 0.34 mg/L,respectively and no nitrate-nitrogen(NO3-N)accumulation was observed.The fish survival rate was above 95%for all the groups.The final fish biomass of the S-10 group(35.83±1.08 kg/m^(3))was not significantly different from the S-0(34.79±1.33 kg/m^(3))group but was significantly higher than S-20(32.6±1.04 kg/m3).The feed conversion ratio for the tilapia in S-20 was 1.46,which was higher than the ratio in S-0(1.40)and S-10(1.39)tilapia.There was no significant difference in the crude protein content of the back muscle from tilapia of the three experimental groups.No significant difference in blood parameters,except for aspartate aminotransferase and alkaline phosphatase was observed between the three groups.Evaluation of microorganisms in the three BFT systems revealed that Proteobacteria,Bacteroidetes,and Fusobacteria were the top three at the phylum level in all groups.However,a significant difference was observed at the genus level in the bacteria of the three BFTs at different salinity(P<0.05).©2017 Published by Elsevier B.V.on behalf of Shanghai Ocean University.This is an open access article。 | Guozhi Luo Wenqing Li Hongxin Tan Xiaoqing Chen | 2017 | Aquaculture and Fisheries2017，2，5： | 5 |
| 15 | Influence of main-panel angle on the hydrodynamic performance of a single-slotted cambered otter-board显示文摘The effect of the main-panel angle of a single-slotted cambered otter-board was investigated using engineering models in a wind tunnel.Three different angles(0,6,and 12)were evaluated at a wind speed of 28 m/s.Parameters measured included:drag coefficient Cx,lift coefficient Cy,pitch moment coefficient Cm,center of pressure coefficient Cp,and the liftedrag ratio Cy/Cx,over a range of angle of attack(0e70).These coefficients were used in analyzing the differences in the performance among the three otter-board models.Results showed that the maximum lift coefficient Cy of the otter-board model with a main-panel angle of 0was highest(1.875 at a¼25).However,when the angle of attack was smaller(0 | Lei Wang Lumin Wang Chunlei Feng Aizhong Zhou Wenwen Yu Yu Zhang Xun Zhang | 2017 | Aquaculture and Fisheries2017，2，5： | 5 |
| 16 | Artificial lights improve the catchability of snow crab (Chionoecetes opilio) traps显示文摘This study investigated the behaviour and commercial catchability of snow crab(Chionoecetes opilio)in response to different low-powered LED lights under laboratory and field conditions.We created a novel choice-experiment in a laboratory setting in which we investigated the behaviour of snow crab in response to coloured LED lights.The results showed that snow crab movement was dependent on light colour,with animals choosing to move toward blue and white lights,away from purple lights,and no detectable effect for green and red lights.We then conducted two field experiments to investigate the effect of the same LED lights on the catch rates of commercial traps during the 2016 snow crab fishery on the east coast of Newfoundland and Labrador.Results from the first field experiment showed that adding white and purple LED lights into baited traps significantly improved Catch Per Unit Effort(CPUE)by 77% and 47% respectively.Results from the second field experiment showed that unbaited traps equipped with only LED lights(no bait),could also catch snow crab in comparable amounts to traditional baited traps,with soak time and depth explaining some of the variation in CPUE.Taken together,these experiments suggest that fishing enterprises can improve their catching performance and profitability by adding LED lights to their traps,or by using LED lights as a bait replacement. | Khanh Q.Nguyen Paul D.Winger Corey Morris Scott M.Grant | 2017 | Aquaculture and Fisheries2017，2，3： | 5 |
| 17 | Isolation and characterization of a heat-resistant strain with high yield of Pyropia yezoensis Ueda(Bangiales,Rhodophyta)显示文摘A heat-resistant Pyropia yezoensis strain YZ-4 was isolated from the regenerated blades of single somatic cells of the wild-type(WT)blades treated with 60Co-g-irradiation.When cultured at 23C and 24C,the survival and division rates of the YZ-4 conchospores were significantly higher than those of WT(P<0.01).After 16 days in culture the survival rates of YZ-4 conchospores were 71.2%and 60.8%at 23C and 24C,respectively,and the division rates of the surviving conchospores were 100%in both cases.Under the same culture conditions,the survival rates of WT conchospores were only 16.9%and 11.5%,and the division rate 99.8%and 81.8%respectively.The resistance of 50-day-aged F1 gametophytic blades of YZ-4 to the temperature rebound was also significantly higher than those of WT(P<0.01).After 30 days in culture at 18C,23C and 24C,the mean blade length increased by 8.5,4.3 and 2.3 times in YZ-4 and was only 3,0.6 and 0.4 times in WT,respectively.The mean blade weight increased 191.9,85.4 and 66.2 times in YZ-4,but only 78.2,7.8 and 4.6 times in WT.On the 15th day WT blades began to decay,but no decay was observed in YZ-4 blades even after 45 days in culture at 23C and 24C.The results obtained indicate that YZ-4 has a higher resistance to higher temperature insults than WT and it might be of value for commercial production of P.yezoensis. | Hongchang Ding Binglei Zhang Xinghong Yan | 2016 | Aquaculture and Fisheries2016，1，1： | 5 |
| 18 | Effect of storage temperature and osmotic pre-treatment with alternative solutes on the shelf-life of gilthead seabream(Sparus aurata)fillets显示文摘The objective of the study was the kinetic modelling of the shelf-life of osmotically pre-treated fish during refrigerated and super-chilled storage.Fresh gilthead seabream(Sparus aurata)fillets were treated for 0-360 min at 15℃ in osmotic solutions 50:5 high dextrose equivalent maltodextrin:NaCl/100 g(HDM),40:10:5 HDM:trehalose:NaCl/100 g(HDM+treh)and 40:10:5 HDM:glucosamine:NaCl/100 g(HDM+gluc).Water loss,solid gain,salt content and water activity were monitored throughout treatment.Slices untreated and osmotically pre-treated for 45 min were aerobically packed and stored isothermally at 15,10,5,2.5,0,-1 and -3℃.Quality assessment was based on microbial growth(total viable count,Pseudomonas spp.,Brochothrix thermosphacta,Enterobacteriaceae spp.,H_(2)S-producing bacteria,lactic acid bacteria,yeasts and moulds),total volatile nitrogen(TVB-N),lipid oxidation(TBARs)and sensory scoring.Quality indices were kinetically modelled and temperature dependence of quality loss rates was modelled by Ratkowsky equation.Osmotic pre-treatment led to significant shelf-life extension of fillets,in terms of microbial growth,chemical changes and organoleptic deterioration.The pre-treatment with the alternative solutes led to depression of the freezing point(-1.8,-2.6,-3.2 and-3.5℃ for the untreated samples and the osmotically pre-treated with HDM,HDM t treh and HDM t gluc,respectively).TVB-N values were higher in untreated samples,followed by osmotically treated fillets,mainly at higher storage temperatures(i.e.10 and 15℃).Based on the mathematical models for sensory evaluation scoring,the shelf-life was 12,19,22 and 22 days at 0℃ for untreated and osmotically pre-treated with HDM,HDM t treh and HDM t gluc fish slices,respectively,while the respective values at -3℃ were 21,35,38 and 38 days.The alternative solutes had no significant effect on the quality and shelf-life of pre-treated fish fillet during storage at refrigerated conditions. | Theofania N.Tsironi Petros S.Taoukis | 2017 | Aquaculture and Fisheries2017，2，1： | 5 |
| 19 | Hydrodynamic performance and structural response characteristics of the double-slotted vertical cambered V-Type otter board显示文摘Vertical cambered V-type otter boards are widely used in large and medium-sized trawlers for their good stability and adaptability to various water layers.However,limited numerical studies on the hydrodynamic performance and structural strength of this type of otter board have been published.In this study,we established the three-dimensional numerical model of the double-slotted vertical cambered V-type otter board according to its special structure and stress feature.We compare the hydrodynamic performance results of our model with those of previous experiments.Using this model,we analyzed the influence of parameters such as attack angle,aspect ratio,dihedral,and deflector angles on its hydrodynamic performance.Moreover,the structural response characteristics of the otter board under typical working conditions were studied.We believe our results will provide theoretical reference for the structural design and optimization of the vertical cambered V-type otter board. | Wenhua Chu Gang Chen Xuchang Ye Xiufang Cui | 2020 | Aquaculture and Fisheries2020，5，4： | 5 |
| 20 | Gladius growth pattern and increment of jumbo squid(Dosidicus gigas)in the tropical Pacific Ocean显示文摘Gladius is an accepted hard tissue for determining the age,size-specific growth,and trophic dynamics of pelagic squid.However,little is known about the inter-and intra-stock variability of gladius growth pattern and increment deposition.In this study,the gladius growth patterns with somatic growth and gonad development were evaluated for two geographic stocks of the jumbo squid(Dosidicus gigas)in the tropical Pacific Ocean.The microstructure and periodicity of the gladius growth increments were also investigated.Results showed varied correlations between four gladius morphometric characteristics with dorsal mantle length,while growth in body weight almost followed a power model.Sexual gladius growth patterns occurred with gonad development,possibly due to different biological functions of these gladius parts and sex-specific energetic allocations.Gladius increments were observed formation in the stem and lateral plate and could be consistently enumerated.The daily periodicity of increment deposition,at least over 144 days old,was validated by comparing gladius increments with the ages obtained from the statoliths.The different oceanographic conditions between two areas likely influence the gladius growth and increment deposition and promote higher increment counts in squid from equatorial waters.Above all,these results provided new information on gladius microstructures and growth increment in different stocks of D.gigas and confirmed the use of this tissue for size-specific growth and age determination. | Yi Gong Yunkai Li Xinjun Chen Xiaodi Gao Ling Chen | 2018 | Aquaculture and Fisheries2018，3，4： | 4 |
