随着淡水养殖事业的不断发展,二龄鱼种需求日益增大,我们通过多年生产实践,提高二龄鳊鱼种产量,亩产达到550公斤获优质二龄鳊鱼种每亩350公斤。每斤12尾左右,满足了市场需求,现将技术经验总结如下。一、池塘的选择,池面积一般在5—10亩,水深达到2.5—3米。水源充足,注排水方便池底平坦,腐植质少,池堤平直整齐,牢固不漏水。二、选择优良的一龄鳊鱼种,提早放养,要选择头小背宽体质健壮体色鲜明,鳞
With the continuous development of freshwater aquaculture, the demand of second-generation fish species is increasing day by day. Through years of production practice, we have increased the production of second-rate anchovy species to 350 kg per mu of high-quality second-aged anchovy species by 550 kg per mu. About 12 per catty, to meet the market demand, technical experience is summarized below. First, the pond’s choice, the pool area is generally 5-10 mu, the water depth of 2.5-3 meters. Sufficient water, easy drainage Note flat bottom, humus less, pool straight and tidy pool, solid watertight. Second, choose a good first-class pomfret species, stocking early, to choose a small back-body physique strong body color bright, scales
