河道投饵网箱与不投饵网箱结合养鱼,能充分利用河道渔业资源和投饵网箱鱼类残饵、粪便,其成本低,风险小,易操作管理,投资收益高。2004年以来驻马店市水产技术推广站在宿鸭湖水库南河道实施推广了该项技术,平均单箱产量1500千克以上。目前河道网箱已发展1000多箱,经济效益和社会效益十分显著。现将技术要点总结如下:
The combination of river feeding cage and feeding cage without fish can make full use of river fishery resources and feeding cage bait and feces of fish, which has low cost, low risk, easy operation and management, and high investment return. Since 2004, Zhumadian Aquatic Technology Extension Station has popularized this technology in the Nanhe River of Suya Lake Reservoir, with an average output of more than 1,500 kg per single tank. At present, the river cage has developed more than 1,000 cases, with significant economic and social benefits. The technical points are summarized as follows:
