| 摘 要： | 持续高强度的捕捞已经严重影响到渔业资源的可持续利用,其对渔业资源的最直接和明显的影响就是资源量的减少.本文对不同捕捞强度作用下,不同生活史和补充量的单鱼种群体的资源量在短期内(1～3a)的变动进行了模拟研究.结果表明,受捕捞影响,鱼类群体资源量在周年内适渐减少,但短寿命种类的资源量比寿命较长的种类更易恢复.年补充量和捕...

| Abstract: | Continuous high strengthfishing effort has seriously affectedthe sustainable utilization of fisheries resource.The most direct and obvious effect caused by fishing is the decrease of fish abundance.Simulation studies about the shot-term(1~3 years) resource variation of single-species with different life histories and recruitment under different fishing intensities were carried out.The results show that fish abundance decreased annually because of fishing.The abundance of species with short longevity was eas... |
