The influence of main ecological and environmental factors on the energy budget of Schlegel＇ s black rockfish Sebastes schlegeli

Acta Oceanologica Sinica 2007年第3期26卷 90-100页

作者： SUN Yao ZHENG Bing ZHANG Bo TANG Qisheng key laboratory for sustainable Utilization of marine fisheries Resources of Ministry of Agriculture Yellow Sea Fisheries Research Institute Chinese Academy of Fisheries Sciences Qingdao 266071 China

In the Maidao Ecological laboratory of the Huanghai Sea fisheries Research Institute in 1998 ~ 2000, the continuous flow-through method was adopted to determine the energy budget components and models of Schlegel＇ s black rockfish under different ecological and environmental factors, such as temperature, food species, body mass and feeding level, etc. The body mass of test fish ranged from 21.2 to 224.5 g. The specific growth rate tended to invert ＂U＂ change with temperature increase. The ecological conversion efficiency showed the same trend as temperature and feeding level rise. Only the specific growth rate tended to decelerate the increment with the rise of feeding level. From the above quantitative relationships, the maximum and optimal growth temper- atures could be obtained as 17.5 and 16.2 ℃, and the maintenance feeding rate and optimum feeding rate as 0.8% and 4. 1% of the body mass. The specific growth rate and ecological conversion coefficient showed a decelerating decrease trend with body mass increment. The small-sized fish food was more advantageous to the feeding level increase in comparison with the small-sized shrimp food, which led to the increase of growth, metabolism and excretion, but had no significant influence on the ecological conversion coefficient. All of temperature, feeding level, body mass and food species can obviously change the energy budget models. The assigning rate of growth energy tended to change along the invert ＂U＂ curve with the increase of temperature and feeding level, and decrease with the body mass increase, but the assigning rates of metabolism energy and excretion energy were quite reverse. These relationships could be quantitatively described as quadratic or power function curve. If the above relationships proved true to other marine fish, the establishment of energy budget model of the same fish under different conditions can be largely simplified.

作者： MA Aijun WANG Xin'an HUANG Zhihui LIU Zhifeng CUI Wenxiao QU Jiangbo Yellow Sea fisheries Research Institute Chinese Academy of Fishery Sciences key laboratory of sustainable development of marine fisheries Ministry of Agriculture Qingdao key laboratory for marine Fish Breeding and Biotechnology Qingdao 266071 China laboratory for marine Biology and Biotechnology Qingdao National Laboratory for Marine Science and Technology Qingdao 266071 China Yantai Tianyuan Aquatic Limited Corporation Yantai 264003 China

In order to carry out the genetic improvement of turbot upper thermal tolerance, it is necessary to estimate the genetic parameters of UTT（upper thermal tolerance） and growth-related traits. The objective of this study was to estimate genetic parameters for BW（body weight） and UTT in a two-generational turbot（Scophthalmus maximus L.） pedigree derived from four imported turbot stocks（England, France, Denmark and Norway）. A total of 42 families including 20 families from G1 generation and 22 families from G2 generation were used to test upper thermal tolerance（40–50 animals per family） in this study and the body weight of individuals were measured. The heritability of BW and UTT and the correlation between these two traits were estimated based on an individual animal model using Bayesian method based on two types of animal models with and without maternal *** results showed that the heritabilities for BW and UTT and phenotypic and genetic correlations between the two traits estimated from model without maternal effects were 0.239±0.141, 0.111±0.080, 0.075±0.026 and–0.019±0.011, respectively. The corresponding values from model with maternal effects were 0.203±0.115,0.055±0.026, 0.047±0.034 and –0.024±0.028, respectively. The maternal effects of BW and UTT were 0.050±0.017 and 0.013±0.004, respectively. The maternal effects had a certain influence on the genetic evaluation of the two traits. The findings of this paper provided the necessary background to determine the best selection strategy to be adopted in the genetic improvement program.

Standardizing CPUE of Ommastrephes bartramii for Chinese squid-jigging fishery in Northwest Pacific Ocean

引用

Chinese Journal of Oceanology and Limnology 2009年第4期27卷 729-739页

作者：田思泉陈新军陈勇许柳雄戴小杰 College of marine Sciences Shanghai Ocean University key laboratory of sustainable Exploitation of Oceanic fisheries Resources Ministry of Education key laboratory of Shanghai Education Commission for Oceanic fisheries Resources Exploitation School of marine Sciences University of Maine

Generalized linear models （GLM） and generalized additive models （GAM） were used to standardize catch per unit fishing effort （CPUE） of Ommastrephes bartramii for Chinese squid-jigging fishery in Northwest Pacific Ocean. Three groups of variables were considered in the standardization： spatial variables （longitude and latitude）, temporal variables （year and month） and environmental variables, including sea surface temperature （SST）, sea surface salinity （SSS） and sea level height （SLH）. CPUE was treated as the dependent variable and its error distribution was assumed to be log-normal in each model. The model selections of GLM and GAM were based on the finite sample-corrected Akaike information criterion （AICC） and pseudo-coefficient （Pcf） combined P-value, respectively. Both GAM and GLM analysis showed that the month was the most important variable affecting CPUE and could explain 21.3% of variability in CPUE while other variables only explained 8.66%. The interaction of spatial and temporal variables weakly influenced the CPUE. Moreover, spatio-temporal factors may be more important in influencing the CPUE of this squid than environmental variables. The standardized and nominal CPUEs were similar and had the same trends in spatio-temporal distribution, but the standardized CPUE values tended to be smaller than the nominal CPUE. The CPUE tended to have much higher monthly variation than annual variations and their values increased with month. The CPUE became higher with increasing latitude-high CPUE usually occurred in 145°E-148°E and 149°E-162°E. The CPUE was higher when SST was 14-21℃ and the SLH from -22 cm to -18 cm. In this study, GAM tended to be more suitable than GLM in analysis of CPUE.

The phenomenon of sex dimorphism prevails among many fi sh species. It has attracted the general research interest due to its close relationship to fi sh growth and thus aquaculture productivity. In Chinese tongue sole ( Cynoglossus semilaevis ), 17β-estradiol (E2) can be used reportedly to induce the feminization of fi sh, although the detailed regulatory network remained elusive. We treated the tongue sole fry before sex diff erentiation with E2 (10 and 30 μg/L) to identify potential targets of E2 in Chinese tongue sole. The E2 treatment indeed induced genetic male fi sh sex-reversal to phenotypic female. Using an iTRAQ-based comparative proteomic analysis, 409 proteins that diff erentially expressed after E2 induction were identifi ed, including 259 up-regulated and 150 down-regulated proteins. Furthermore, 19 diff erentially expressed proteins identifi ed in the comparative proteomic analysis were selected to assess their transcription and eight of them exhibited the same tendency. Functions of the eight proteins included mainly nucleotide and protein binding. Interestingly, a far upstream element-binding protein 3-like isoform exhibited the signifi cant upregulation both at transcription and translation levels after E2 treatment. This work identifi ed a set of candidate proteins for E2 response and deepened our understanding of E2 regulatory mechanism.
