摘要:: ］2006年5月、8月、11月和2007年2月，对浙江南部外海渔场使用底拖网进行渔业资源调查.据其资料，使用扫海面积法估算浙江南部外海底层渔业资源量以及可捕量.结果表明：采集并鉴定的种类共416种，现存资源量为442 525.89 t，使用Camida估算模式和简化估算模式得到总可捕量分别为238 077.32 t和214 625.06 t.鱼类、甲壳类和头足类的资源平均密度及现存资源量分别为2 374.68 kg/km2和271 225.74 t、451.08 kg/km2和 51 520.47 t、875.17 kg/km2和99 957.98 t.为防止资源盲目开发及资源衰退，浙江南部外海拖网捕捞结构宜进行控制和调整

Abstract:: On the basis of the bottom trawl fishery resource investigation in the offshore water of south Zhejiang in May,August,November 2006 and February 2007,this paper estimated the abundance and allowable catch of demersal species.The results showed that 4~16 species were identified whose abundance was 442 525.89 t,and the allowable catch that estimated from Camida mode and simple mode was 238 077.32 t and 214 625.06 t,respectively.The average density and abundance for fish,crustacean and cephalopod were 2 374.68 kg/km2 and 271 225.74 t,451.08 kg/km2 and 51 520.47 t,875.17 kg/km2 and 99 957.98 t,respectively.The structure of trawl catch should be controlled and adjusted to prevent blindfold exploitation and the consequent resources decline
