摘要
根据三倍体虹鳟(Oncorhynchus mykiss)与普通虹鳟相似的生活习性,利用现有的池塘条件开展三倍体虹鳟养殖试验。共放养规格15 g/尾的鱼种1万尾,放养密度111尾/m^(2),经299 d的饲养,平均规格达750 g/尾,单位产量23.4 kg/m^(2)。养殖过程利用河水与井水相结合的方式,利于调控水温和水量,促进三倍体虹鳟生长速度快、成活率高的优势展现。
According to the similar habits of triploid Oncorhynchus mykiss and common O.mykiss,trial for farming of triploid O.mykiss was carried out with currently available pond.10000 seedlings with size of 15 g/ind.were stocked with density of 111 ind./m^(2).After 299 days,the fish reached the size of 750 g/ind.and the average yield was 23.4 kg/m^(2).During farming water supply came from both river and underground water,which made it easier to adjust water temperature and quantity and show the strengthes of triploid O.mykiss of growing fast and high survival rate.
