鲈鱼属广盐性鱼类,我国沿海均有分布,资源丰富。鲈鱼生长快,适应性广,抗病力强,肉质鲜美。春季到海区捕捞鲈鱼苗放入池塘中进行淡水养殖,到年底鲈鱼尾重可达0.5～1公斤,亩产超过1000公斤,养殖效益较高。 一、池塘建造 选择水源充足、水质清新无污染的地方建池。每口池塘面积5—8亩,长方形,南北走向较好。要求池底平坦,沙泥底质,池岸牢固,池深2米。池底埋设进排水管道,配备增氧机。放养前对池塘清淤消毒。施肥培养基础饵料,使池水呈油绿色或茶褐色。 二、苗种培育 从海区捕捞的鲈苗(体长1.5—2厘米)经过淡化至盐度
Perch is a broad-salt fish, both in China’s coastal distribution, rich in resources. Bass fast growth, wide adaptability, disease resistance, meat quality. In the spring, sea bass perch fry will be put into the pond for freshwater aquaculture. By the end of the year, the perch will weigh up to 0.5 kg to 1 kg per mu and more than 1000 kg per mu, resulting in higher breeding benefits. First, the choice of adequate water pond construction, clean water pollution-free place to build the pool. Each pond area of 5-8 acres, rectangular, north and south to better. Requires a flat bottom, sand sediment, pool shore firm, 2 meters deep pool. Bottom buried in the drainage pipe, equipped with aerator. Stocking the pond before decontamination. Fertilization basal diet, so that the pool was oily green or brown. Second, seed cultivation Seabirds fishing from the sea (body length 1.5-2 cm) after desalination to salinity
