本文用1996年、1997年浙江温岭渔7515、754两艘单拖渔轮的调查资料,采用资源密度面积法,对26°30′～30°00′N122°～126°30′E、20～150m水深海区的头足类的资源量进行评估。评估结果是:调查海区头足类资源量1996年为29055.84t,其中太平洋褶柔鱼为353.36t,剑尖枪乌贼为10734.10t,乌贼类为12384.9t,章鱼为5583.45t;1997年为35004.52t,其中太平洋褶柔鱼为1176.04t,剑尖枪乌贼为20511.30t,乌贼类为9658.50t,章鱼为3658.69t。东海区头足类资源量1996年为131747.81t,其中太平洋褶柔鱼为1602.24t,剑尖枪乌贼为48671.60t,乌贼类为56157.00t,章鱼为25317.02t;1997年为189441.07t,其中太平洋褶柔鱼为6364.61t,剑尖枪乌贼为111005.17t,乌贼类为52270.87t,章鱼为19800.48t。
Based on the survey data of two mono-trailer fishing trawlers from Wenling fishery of Zhejiang Province in 1996 and 1997, the area density of 26 ° 30 ’~ 30 ° 00’N122 ° ~ 126 ° 30’E, 20 ~ 150m Water depth of the Cephalopod resources assessment. The results of the assessment are as follows: The resources of Cephalopod in the surveyed sea area were 29055.84 tons in 1996, of which 353.36 tons in Pacific Ocean, 10734.10 tons in Sword Point Squid, 12384.9 tons in squid, 5583.45 tons in octopus and 35004.52 tons in 1997 Among them, Pacific tilapia was 1176.04 t, swordhead squid was 20511.30 t, squid was 9658.50 t and octopus was 3658.69 t. In the East China Sea, the amount of cephalopods was 131747.81t in 1996, of which 1602.24t for Pacific Tortoise, 48671.60t for squid, 56157.00t for squid and 25317.02t for octopus; 189441.07t for 1997, of which the Pacific Ocean fold Squid is 6364.61t, swordhead squid is 111005.17t, squid is 52270.87t, octopus is 19800.48t.
