为改变以往黄河三角洲地区团头鲂只作搭配品种的养殖方式,我们于2005年在永安镇东三村进行了“池塘主养团头鲂高产技术试验”研究,试验水面1．87 hm~2 (28亩),总净产成鱼18377．96 kg,平均每667 m~2净产658．94 kg,其中团头鲂平均每667 m~2净产461．02 kg,平均规格347．9 g,每667 m~2纯收入2 184．28元,投入产 In order to change the breeding methods of the pasture only in the Yellow River Delta region, we conducted the “High-yielding Technical Experiment of Tropica (Coccinella tataricola) in ponds” in Dongsancun, Yongan Town in 2005. The water level of 1.87 hm ~ 2 28 mu). The net fish yield was 18377.96 kg, with a net yield of 658.94 kg per 667 m ~ 2, with an average of 461.02 kg per 667 m ~ 2 and an average specification of 347.9 g , Each 667 m ~ 2 net income 2 184.28 yuan, put into production
