湖北省当阳市实用枝术研究所应广大养殖户“小面积高密度网箱防盗”养殖的要求,经连续三年的多点试验,结合台湾水产专家苏文炳先生的经验,成功地完成了“微型封闭式高密度网箱养鳅”的课题。该成果设备投资仅20元,年产巨型泥鳅200～260公斤,产值达2000元以上。整个养殖管理过程轻松愉快,成活率高达92.3％,铒料利用率达100％。由于采用全封闭式网箱,杜绝了常发生的盗鱼现象。现将该技术要点介绍如下,您不妨一试。 一、网箱的制作。该网箱仅一立方米容量大小,箱底中央下垂一无网眼的锥形兜,即为饵料兜,可防止饵料的流失。同时,可因泥鳅的活动而不停摆动,增强 Dangyang City, Hubei Province practical branch of the Institute should be the majority of farmers “small area high density cage security” breeding requirements, after three consecutive years of multi-point test, combined with the experience of Taiwan’s aquatic experts Su Wenbing, successfully completed the “ Micro-closed high-density cage feeding loach ”issue. The result of investment in equipment is only 20 yuan, with an annual output of giant loach 200 ~ 260 kg, the output value of more than 2,000 yuan. The whole process of aquaculture management is easy and pleasant, with a survival rate of 92.3% and a utilization rate of 100%. Due to the use of fully enclosed cage, put an end to the phenomenon of frequent burglary. The technical points are introduced below, you may wish to give it a try. First, the production of cages. The capacity of the cage is only one cubic meter, the bottom of the bottom of a hanging mesh-free cone pocket, that is bait pocket, to prevent the loss of food. At the same time, due to loach activity and kept swinging, enhanced
