成立闽台远洋渔业协会的思考与构想     

何姗  舒展 《台湾农业探索》2013,(6):6-11

闽台两岸远洋渔业在政治、经济、社会文化上都具备成立闽台远洋渔业协会的可能性,加之目前闽台两地在远洋渔业捕捞的国际环境进一步恶化及闽台两岸远洋渔业经济发展都共同面临着多项挑战,这些因素使得成立闽台远洋渔业协会势在必行,该文拟对成立闽台远洋渔业协会机构设置进行初步构思,对闽台远洋渔业协会成立的意义进行思考,旨在促进两岸对远洋渔业的合作,为维护“祖产”而共同努力。  相似文献   

中西太平洋金枪鱼围网自由鱼群捕获率与渔场温跃层特性的关系   总被引：1，自引：0，他引：1

温跃层特性与金枪鱼表层渔业的捕捞成功率有关,但温跃层特性随海域与季节的不同而变化,因此对于捕捞成功率的影响也不同。分析了中西太平洋我国金枪鱼围网船队作业渔场的温跃层特性,并结合海上实测的围网沉降性能与对应的生产资料,探讨了金枪鱼围网捕获成功率与温跃层特性的关系,结果表明：（1）调查期间91.2%的网次所对应的温跃层顶界深度超过100 m,温跃层顶界深度较深是该海域渔场温跃层的重要特征;（2）围网最大沉降深度的95%置信区间为［185.0, 197.8］ m,渔场温跃层顶界深度的95%置信区间为［146.0, 158.3］ m,网具穿越温跃层顶界后继续沉降的深度的95%置信区间为［34.3, 44.0］ m;（3）相关分析表明,本研究中金枪鱼围网的捕获成功率与温跃层特性并不存在显著的相关性（P>0.05）,这可能是由于当地渔场较深的温跃层顶界深度使得目标鱼种在网具到达温跃层之前拥有充分的逃逸时间和空间,从而导致温跃层内急剧变化的温度梯度失去了阻碍作用。  相似文献

Profile of a fishery collapse: why mariculture failed to save the large yellow croaker   总被引：1，自引：0，他引：1  

Min Liu  & Yvonne Sadovy de Mitcheson 《Fish and Fisheries》2008,9(3):219-242

The large yellow croaker (Larimichthys crocea), endemic to East Asia was once one of the three top commercial marine fishes of China PR. Heavily exploited since the 1950s, wild stocks were so severely depleted by the 1980s that most individuals subsequently sold originated from hatcheries. After peaking at about 200 000 tonnes in the mid‐1970s, catches of the croaker in China PR declined by over 90% within just 2 decades; according to most decline criteria this would categorize the croaker as “threatened” and management measures, including restocking, were developed. The extensive government‐sponsored mariculture program introduced to address food supply and overfishing in the 1980s, particularly of the croaker, was one of the earliest for marine finfish, not only in China PR, a nation with a rich and highly successful history in aquaculture, but globally. In this first, in‐depth, profile of a key fishery and early mariculture development, we integrate ecological and biological information with the fishing, management, mariculture and economic history to trace the collapse of wild stocks and assess why management and mariculture did not result in wild stock recovery. Evidence strongly suggests that a combination of heavy exploitation of spawning and over‐wintering aggregations, poor management and overfishing pressure were major factors in stock declines, with contributions from pollution, habitat degradation and marine ecosystem shift. Although the croaker proved a highly successful mariculture candidate, with approximately 70 000 tonnes produced in 2005, the highest of any marine fish cultured in China PR, mariculture and restocking have failed to restore croaker stocks and may have, inadvertently, led to biodiversity losses. The detailed history of the croaker is a sobering reminder that successful mariculture, albeit important for food production and livelihoods, is not necessarily a solution to overfishing, and moreover, may have compromised fishery recovery by competing for funds, attention, space, and maybe genetic resources.  相似文献   

Landings, logbooks and observer surveys: improving the protocols for sampling commercial fisheries   总被引：1，自引：0，他引：1  

A J R Cotter  & G M Pilling 《Fish and Fisheries》2007,8(2):123-152

The sampling of commercial marine fisheries for management purposes often displays a key weakness in the form of poor documentation of the scientific basis of sampling and estimation, the assumptions made, and the practical constraints. This paper reviews systematically the theoretical and practical options that can remedy this situation and recommends that decisions be archived in regularly updated ‘Sampling Approach and Modifications’ (SAM) documents. Defining the target population, the observable population (usually a subset of the target), and the assumed links between them is important, along with the distinction between design‐ and model‐based sampling approaches. Fleet‐targeted and stock‐targeted sampling strategies are contrasted, the latter being much harder to implement. Sampling protocols aimed at estimating quantities of fish landed and discarded, length–frequency distributions, length‐related variables such as age, weight and maturity, and ratio variables such as catch per unit of effort and the proportions of discards are discussed, together with the raising of estimates to fleet and/or stock levels. The ideas are summarized in the specific contexts of landings sampling, logbook schemes and sea‐going observer surveys. SAMs are commended for enhancing the scientific value of fishery sampling, and for encouraging methodological discussions among users and producers of the data.  相似文献

Effects of hydrologic regulation on icefish population dynamics,assemblage structure and fishery yield in Lake Nanyi,China     

Zhongsuo Wang  Zhongcheng Yan  Longjun Xu  Xinxin Lu  Kirk O. Winemiller  Guangchun Lei 《Ecology of Freshwater Fish》2013,22(4):637-644

Stock dynamics and demographic parameters of a family of annual icefishes (Salangidae) were investigated in Lake Nanyi in eastern China before and after construction of irrigation infrastructure. After hydroregulation, two of four icefish species, a migratory species (Hemisalanx brachyrostralis) and a previously rare species (Neosalanx tangkahkeii) were absent from survey samples. The relative abundance of the remained icefish stocks changed greatly. The spring and autumn stocks of N. taihuensis increased from 9.9% and 1.7% to 74.8% and 4.8%, respectively, and N. oligodontis decreased from 84.8% to 20.4%. Total icefish density (CPUE) and yield doubled under the new hydrologic regime. Average adult body size and absolute fecundity of the three persistent icefish stocks decreased, and this could have resulted from slower rates of growth and development of larvae and juveniles in response to greater density of icefishes overall and more intense competition for planktonic food resources during summer and fall.  相似文献
