大银鱼池养试验表明:受精卵在池塘中自然孵化率47.2%,孵化期38—48d。池塘中长大的成鱼发育正常并能自然繁殖。桡足类和枝角类是池养大银鱼的主要食物。池养大银鱼的体长一体重关系式为 W=2.051×10~(-6)L~(2.9856),体重拐点月龄6.42,拐点体重6.89g。此外,还进行了室内不同温度和盐度条件下受精卵的孵化实验。
Large silver fish ponds experiments showed that: fertilized eggs in the pond of 47.2% of the natural hatching rate, incubation period 38-48d. Adult fish growing up in ponds develop normally and naturally multiply. Copepods and cladocerans are the main food for pond-raised silverfish. The body length and body weight of pool broodstock was W = 2.051 × 10 ~ (-6) L ~ (2.9856), body weight inflection point age 6.42, inflection point weight 6.89g. In addition, hatching experiments of fertilized eggs under different temperature and salinity conditions in the interior were carried out.
