【摘要】 根据2000~2001年福建近海渔业资源的现场调查和检测结果,并结合福建近海多年海洋科学调查研究所获得的初级生产力资料,应用生态系统营养动力学模型估算渔业资源(包括鱼类、甲壳类和头足类)生产量和最大可持续开发量.研究结果表明:营养动态模型和Cushing模型估算福建近海渔业资源生产量分别为267.91×104和294.58×104t,平均为281.25×104t.Cadima模式估算的最大可持续开发量为164.46×104t,而1994年以来福建近海实际年渔获量在179.81×104~239.39×104t,已连续10年超过了渔业资源的最大可持续开发量;投入的捕捞力量也已连续10年超过剩余产量模式估算的最大可持续捕捞力量,呈现渔获量和捕捞力量"双超"的局面.更多还原

【Abstract】 Based on the fishery resource investigation in 2000~2001 in Fujian coastal water,and primary productivity collected from the marine science surveys.We used the ecological Trophodynamics models to estimate the productivity and the maximum sustained yield (MSY),including fish,crustaceans and cephalopod.The result showed that the productivity of fishery resources are 267.91×104 and 294.58×104 t by Trophodynamics model and Cushing model respectively.The average is 281.25×104 t,and the MSY is 164.46×104 t.The annual catches have been from 179.81×104 t to 239.39×104 t since 1994,which has reached the MSY for 10 years.The devoted fishing efforts have exceeded the maximum sustained efforts for 10 years also.更多还原
