池塘集约化养殖鳜鱼是一项投资大、效益高,同时风险也大的生产模式。为避免经营者的盲目性,笔者现根据本地实践,借鉴外地经验,总结鳜鱼池塘精养的几点关键技术,以供参考。 1、选择适宜池塘 主养鳜鱼的池塘不宜过大或过小,面积过大饵料鱼难以满足,鳜鱼个体生长差异大;过小,水质变化快,难以控制。一般,鳜鱼主养池塘面积以1000—3335m~2为宜。要求选择背风向阳、沙壤土底质、淤泥较少或没有淤泥的新开池塘,池底平坦,略向排水口倾斜,水深2m左右,灌排水系统完善,水源充足、清新、无污染,水质良好。池塘需经干塘曝晒,放养前 Intensive farming ponds Pomfret is a large investment, high efficiency, but also a big risk of the production model.
