关于东海区灯光围网管理的研究

对1998～2005年东海区灯光围网的主捕品种、数量分布及其捕捞规模进行调研,研究认为灯光围网的主捕品种为日本鲐、澳洲鲐、竹筴鱼和蓝圆鲹等,且尚有一定的资源量。东海区的灯光围网近年来规模发展迅速,对上述鲐鲹鱼有良好的诱捕效果。从可持续利用资源角度出发,对其应实施规范管理,其措施为:(1)确定大型机轮围网、机帆船灯光围网的规模数量、渔船吨位、马力、网具规格等;(2)实行捕捞许可证制度;(3)成立全国灯光围网协会,配合农业部渔业局对灯光围网制订有关措施,进行专项管理。

The Research of Management by Light-Seine in the East China Sea

From 1998 to 2005 the main fishing seed,the number distribution and the scale of fishing in the area of East China Sea by light-seine were investigated.It was cohcluded.that the main fishing seed by light-seine is Scomber japonicus,Pneumatophorus tapeinocephalus,Trachurus japonicus,Decapterus maruaelsi and so on,and also there is certain stock size.The scale of fishing by light-seine in the East China sea has developed quickly in recent years,and there are good efficacy of traps on above-mentioned chub mackerel and round scad.Considering sustainable utilization resources,it should be managed canonically.The measurs are as follows: first,make sure the scale,number,fisher tonnage,the standard of horsepower and netting gear of the arge-scale engine wheel purse netn,engine sailing vessel,second,carry out the licence system,third,come into existence countrywide light-seine association,assorte agriculture department fishery office set down the measure of light-seine,carry out special management.
