中文摘要:
      随着捕捞强度的加大,渔业生物为了应对捕捞压力维持种族繁衍逐渐产生适应性进化,这一过程称为捕捞诱导进化(fishing-induced evolution, FIE),通常表现为渔业生物个体变小、性成熟提前,个体对捕捞的敏感性增强,进一步导致渔业种群结构简单化、生态系统稳定性下降和渔业经济效益降低。认知捕捞诱导的渔业生物适应性进化,掌握捕捞对渔业种群的作用机制,有利于制定科学合理的渔业资源养护与管理策略。虽然FIE方面已进行了大量研究,但是FIE在生理、生态及基因层面上对渔业生物的具体影响过程尚未明确,尤其是在气候变化、多物种相互作用等的动态环境中,FIE的作用方式更为复杂。本文综述了鱼类FIE的主要研究方法,总结了捕捞对大个体的选择性在鱼类生长、性成熟和行为方面的影响,并分析了这种影响对渔业种群恢复与管理产生的效应,以及今后需要解决的关键科学问题,旨在为FIE的进一步深入研究和渔业资源的科学管理提供帮助。
英文摘要:
      With the increase of fishing intensity, fishery organisms gradually evolve adaptively in response to fishing pressures and maintaining the reproduction of the population. This process is called fishing-induced evolution (FIE). Nowadays, many fishery organisms in the world have experienced the evolution of biological characteristics. For example, Atlantic cod (Gadus morhua), small yellow croaker(Larimichthys polyactis), etc. became smaller and mature earlier, which further leads to the simplification of fishery population structure, the decline of ecosystem stability and the reduction of fishery economic benefits, finally seriously affects the sustainable development of fishery resources in many countries. Therefore, it is essential to recognize the fishing-induced adaptive evolution and grasp the mechanism of fishing effects on fishery resources, in order to formulate a scientific and rational strategy for recovery and management of fishery resources. Although FIE has been widely concerned, the mechanisms underlying the impacts of fishing on physiological, ecological and genetic characteristics are not clear to this day, especially in the dynamic environment of climate change and multi-species interactions, the role of FIE is more complex due to a number of influence factors and the complex evolutionary process. The existed studies mainly focus on fishing-induced changes in fish biological traits, computer-simulated population resilience and fishery resource management strategies, etc., but rarely on the mechanisms of FIE. Here, we reviewed the main research methods of fish FIE including methods of field ecology, experimental ecology, numerical simulation and genetics. We summarized the related research results that fishing affects fish body length, sexual maturity, behavior, etc. by selecting the bigger individuals which is the most important kinds of fisheries(bottom trawl), and analyzed the effects on the fish population recovery and management of fishery stocks. At last, we concluded the key scientific problems which should be solved in the future, in order to provide help for further FIE research and scientific management of fishery resources.
