Copper (Cu) contamination in the environment has been increased during the years with agricultural and industrial activities.Biotechnological approaches are needed for bioremediation in these areas. The aims of this study were i) to evaluate the phytoremediation capacity of the high-yielding bioenergy plant castor bean (Ricinus communis L.) in vineyard soils (Inceptisol and Mollisol) contaminated with Cu and a Cu mining waste; ii) to characterize the castor bean as a Cu phytoremediation plant; and iii) to evaluate the nutrient uptake by castor bean. Castor bean plants cultivated in soil with toxic levels of Cu for 57 d exhibited high phytomass production, a high tolerance index of roots' fresh mass and shoots' dry mass, a high level of Cu phytoaccumulation in the roots and also, a robust capacity for Cu phytostabilization. Furthermore, castor bean plants did not significantly deplete soil nutrients(such as N, P, and Mg) during cultivation. Plants cultivated in Inceptisol, Mollisol and Cu mining waste exhibited a strong potential for Cu phytoaccumulation, with values of 5 900, 3 052 and 2 805 g ha-1, respectively. In addition, the castor bean's elevated phytomass production and strong growth in Cu-contaminated soils indicated a high level of Cu phytoaccumulation and a potential application in biofuels. These findings indicate that the castor bean is a efcient hyperaccumulator of Cu and a potential candidate plant for the phytoremediation of Cu-contaminated soil.

An 8-week feeding trial was conducted to determine the optimal dietary protein level for juvenile marbled flounder.Five semi-purified test diets were formulated to contain different protein levels(CP)including 42.7%,47.4%,53.3%,58.8%,and 64.5%(dry matter),named as CP42.7,CP47.4,CP53.3,CP58.8,and CP64.5,respectively.Five hundred and twenty-five juveniles(6.0±0.1 g)were randomly distributed into 15 tanks(300 L tanks),resulting in 35 fish per tank(n-3 tanks).Fish were fed the test diets 5 times per day until satiation.The CP58.8 resulted in the highest gain in weight and the best efficiency in feed utilization among the tested protein levels(P<0.05).Fish fed the CP58.8 diet showed significantly higher whole-body protein and lipid contents than the fish that were fed the other diets(P<0.05).Fish fed the CP53.3,CP58.8,and CP64.5 diets showed a significantly higher dorsal-muscle lipid content than the fish that were fed the CP42.7 and CP47.4 diets(P<0.05).The one-slope straight broken-line regression analysis on the results of the thermal growth coefficient and feed conversion ratio indicated that the estimated optimum dietary protein level was 58.8%.Taken together,it is suggested that the dietary protein level of 58.8%is optimal for better growth and high efficiency in feed utilization for the juvenile marbled flounder.

We evaluated the effect of pH on larval development in larval Pacific oyster(Crassostrea gigas) and blood cockle(Arca inflata Reeve).The larvae were reared at pH 8.2(control),7.9,7.6,or 7.3beginning 30 min or 24 h post fertilization.Exposure to lower pH during early embryonic development inhibited larval shell formation in both species.Compared with the control,larvae took longer to reach the D-veliger stage when reared under pH 7.6 and 7.3.Exposure to lower pH immediately after fertilization resulted in significantly delayed shell formation in the Pacific oyster larvae at pH 7.3 and blood cockle larvae at pH 7.6 and 7.3.However,when exposure was delayed until 24 h post fertilization,shell formation was only inhibited in blood cockle larvae reared at pH 7.3.Thus,the early embryonic stages were more sensitive to acidified conditions.Our results suggest that ocean acidification will have an adverse effect on embryonic development in bivalves.Although the effects appear subtle,they may accumulate and lead to subsequent issues during later larval development.

China Ocean Engineering 2019年第2期33卷 185-197页

作者： WANG Kun DU Jing LIU Ming WU Jin-hao JIANG Heng-zhi JIN Sheng SONG Lun Liaoning Ocean and fisheries Science research Institute national Marine Environment Monitoring center College of Hydraulic Engineering Dalian University of Technology

The Bohai Sea is a seasonal icy sea area that has the lowest latitude of any sea experiencing icing in the northern hemisphere, and simulation studies on oil spills during its sea ice period are the key to analyzing winter oil spill accidents. This study applied the three-dimensional free surface to establish a high-resolution hydrodynamic model and simulate tidal distributions in the Bohai Sea. Then, the oil spill model of the open sea area and thermodynamic model were combined to establish a numerical model for the Bohai oil spill during the winter sea ice period. The hydrodynamic model and sea ice growth and melting model were verified, and the parameters were adjusted based on the measured values, which indicate that the numerical model established in this paper is of high accuracy,stability and ubiquity. Finally, after checking the calculations repeatedly, the diffusion coefficient for the Bohai Sea was determined to be 1.0×10^(–7 )m^2/s. It is better that the comprehensive weathering attenuation coefficient is lower than that of a non-winter oil spill, with 1.3×10^(–7 )m^2/s being the most appropriate coefficient. This study can provide the reliable technical support for the operational safety and reduction in losses caused by winter oil spill accidents for the petroleum industry.

Evaluating the Ryman-Laikre effect for marine stock enhancement and aquaculture

引用

Current Zoology 2016年第6期62卷 617-627页

作者： Robin S. WAPLES Kjetil HINDAR Sten KARLSSON Jeffrey J. HARD national Marine fisheries Service Northwest Fisheries Science Center 2725 Montlake Boulevard East Seattle WA 98112 USA Norwegian Institute for Nature research (NINA) Trondheim 7485 Norway

The Ryman-Laikre (R-L) effect is an increase in inbreeding and a reduction in total effective population size ( ) in a combined captive-wild system, which arises when a few captive parents produce large numbers of offspring. To facilitate evaluation of the R-L effect for scenarios that are relevant to marine stock enhancement and aquaculture, we extended the original R-L formula to explicitly account for several key factors that determine , including the numbers of captive and wild adults, the ratio of captive to wild (), productivity of captive and wild breeders, and removal of individuals from the wild for captive breeding. We show how to provide quantitative answers to questions such as: What scenarios lead to no loss of effective size? What is the maximum effective size that can be achieved? and What scenarios insure that will be no smaller than a specified value? Important results include the following: (1) For large marine populations, the value of becomes increasingly important as the captive contribution increases. Captive propagation will sharply reduce unless the captive contribution is very small or is very large (∼10 or higher). (2) Very large values of are only possible if wild is tiny. Therefore, large wild populations undergoing captive enhancement at even modest levels will suffer major reductions in effective size unless wild is a tiny fraction of the census size (about 10 or lower).

Acta Oceanologica Sinica 2022年第8期41卷 41-51页

The modern fishery stock assessment could be conducted by various models,such as Stock Synthesis model with high data requirement and complicated model structure,and the basic surplus production model,which fails to incorporate individual growth,maturity,and fishery selectivity,etc.In this study,the Just Another Bayesian Biomass Assessment(JABBA)Select which is relatively balanced between complex and simple models,was used to conduct stock assessment for yellowfin tuna(Thunnus albacares)in the Atlantic Ocean.Its population dynamics was evaluated,considering the influence of selectivity patterns and different catch per unit effort(CPUE)indices on the stock assessment results.The model with three joint longline standardized CPUE indices and logistic selectivity pattern performed well,without significant retrospective pattern.The results indicated that the stock is not overfished and not subject to overfishing in 2018.Sensitivity analyses indicated that stock assessment results are robust to natural mortality but sensitive to steepness of the stock-recruitment relationship and fishing selectivity.High steepness was revealed to be more appropriate for this stock,while the fishing selectivity has greater influence to the assessment results than life history parameters.Overall,JABBA-Select is suitable for the stock assessment of Atlantic yellowfin tuna with different selectivity patterns,and the assumptions of natural mortality and selectivity pattern should be improved to reduce uncertainties.

Use of natural trophic resources by Eastern oysters and Pacific oysters of different ploidy

Ploidy manipulation,such as triploidy,in farmed oysters has been used as a tool to enhance oyster quality throughout all seasons because triploid oysters allocate less energy to gametogenesis,and therefore are deemed better performers than fertile diploids.Nevertheless,scientific reports describing no differences between ploidies and,in certain conditions,disadvantages of triploids are not uncommon.As the use of triploid oyster seed increases culture cost for growers,consistency in performance of triploids is considered to be an important goal.Thus,research to assess how ploidy affects physiological processes underlying oyster performance is fundamental for the aquaculture industry.This work was undertaken to assess if ploidy-based differences in performance in the two most commonly cultivated commercial species of oyster in the United States,Crassostrea virginica and Crassostrea gigas,are associated with filtration,feeding,and metabolism.To test this hypothesis,biodeposition measurements were made with oysters exposed to ambient water conditions at locations and seasons providing a variety of environmental conditions.Oysters did not show differences in filtration and feeding associated with ploidy,but physiological feeding variables fluctuated with environmental characteristics associated with spatial and seasonal differences.A preliminarily test of the hypothesis that differences in energy metabolism may account for differences in performance among ploidy levels indicates that basal metabolic rates of diploid,triploid,and tetraploid Eastern oysters are not different.

Morphological beak differences ofloliginid squid, Uroteuthis chinensis and Uroteuthis edulis, in the northern South China Sea

引用

Journal of Oceanology and Limnology 2018年第2期36卷 559-571页

作者：金岳刘必林陈新军 Kevin STAPLES College of Marine Sciences Shanghai Ocean University national Distant-water fisheries Engineering research center Shanghai Ocean University The Key Laboratory of Sustainable Exploitation of Oceanic fisheries Resources Ministry of Education Shanghai Ocean University Collaborative Innovation center for national Distant-water fisheries School of Marine Sciences University of Maine

The mitre squid(U roteuthis chinensis) and the swordtip squid( U. edulis) are Indo-Pacific cephalopod species that are abundant in the western Pacific Ocean. They are currently exploited in the East and South China Seas and make up a significant portion of the Chinese neritic squid catch. Beaks, the feeding organs of squid, are important for individual size and biomass estimation because of their high resistance to degradation in predator stomachs and consistent dimensions. In this study, 104 U. chinensis and 143 U. edulis individuals were sampled from northern South China Sea with mantle length from 70 to 260 mm and 96 to 284 mm, respectively. The results indicated that morphological beak values were greater for U. edulis, compared to U. chinensis, for upper hood length(UHL), upper crest length(UCL), upper lateral wall length(ULWL), lower crest length(LCL), and lower lateral wall length(LLWL). According to principal component analysis, UHL/ML, UCL/ML, ULWL/ML, LCL/ML, LLWL/ML and LWL/ML could represent the characteristics of beaks for U. chinensis, while UHL/ML, UCL/ML, ULWL/ML, LHL/ML, LCL/ML and LLWL/ML could represent it for U. edulis. According to Akaike's information criterion(AIC) values, a power function was the most suitable model for U. chinensis, while a linear function was the most suitable model for U. edulis. The beak variable-mantle length ratio(beak variable/mantle length) declined with the increasing of mantle length and declined sharply at the early stage of growth in both beaks and species. The ratio changed quickly after achieving the mantle length of 140 mm for U. chinensis, while the ratio changed quickly after 170 mm for U. edulis. Beaks in both species experienced sharper changes through maturity stage I to II than other maturity stages. This study gives us basic beak morphology information for U. chinensis and U. edulis in the East and South China Seas. Geometric morphological methods combined with dietary analysis should be used in the future.

Insights into the genetic covariation between harvest survival and growth rate in olive flounder(Paralichthys olivaceus)under commercial production environment

引用

Aquaculture and fisheries 2023年第2期8卷 135-140页

作者： Yangzhen Li Yuanri Hu Yingming Yang Weiwei Zheng Shandong Key Laboratory of Marine fisheries Biotechnology and Genetic Breeding Yellow Sea Fisheries Research InstituteChinese Academy of Fishery SciencesQingdao266071China Laboratory for Marine fisheries Science and Food Production Processes Pilot National Laboratory for Marine Science and Technology(Qingdao)Qingdao266237China national Demonstration center for Experimental fisheries Science Education Shanghai Ocean UniversityShanghai201306China

In aquaculture,selective breeding for survival till harvest have become an alternative strategy for improving disease resistance and production.However,knowledge of genetic parameters of harvest survival,e.g.,heritability and genetic correlations between survival and growth rate traits,is still scarce.The aims of this study were to estimate genetic parameters for harvest survival and growth rate traits under commercial farming conditions in olive flounder(Paralichthys olivaceus).Harvest survival was defined as a binary trait;growth traits were measured as average daily gain(ADG),specific growth rate(SGR),daily growth coefficient(DGC)and body weight(BW).Data from a population of 241 full-sib families(involving 39,904 individuals,four generations)were used.Heritabilities of survival were low but significant,which were 0.15±0.04 and 0.22±0.01 on observed and underlying scale,respectively.Heritability estimates for ADG,SGR and DGC were medium to high,which were 0.33±0.06,0.83±0.07,0.58±0.07,respectively.While the heritability of BW is of low magnitude(0.17±0.08).The genetic correlations between harvest survival and three growth rate traits(i.e.,ADG,SGR and DGC)were very strong(ranging from 0.66 to 0.79),which is an exciting result.However,the genetic correlation between harvest survival and BW was much lower(0.17±0.08).These results suggest that selection for harvest survival would consequentially result in concomitant increase of growth rate,and vice versa.Our findings revealed novel insights into the genetic improvement of growth rate and harvest survival through genetic selection in olive flounder.
