大黄鱼的网箱养殖和越冬技术

Cage culture and overwintering techniques of Pseudoseciaena crocea

摘要:

在天然海区用网箱养殖大黄鱼鱼种和成鱼，并进行了鱼种越冬试验。结果表明：鱼种阶段大黄鱼生长速度呈指数增长，这与放养密度减低有关；成鱼阶段大黄鱼生长速度较为均匀。大黄鱼在浙江象山地区能自然越冬，并经二年饲养可达到上市规格。

Abstract:

In the natural sea zone, fingerling and adult Pseudoseciaena croceas were cultured in net cages, and the experiment of fingerling overwintering was done. The result indicated that at fingerling stage, the growth speed of P. crocea could exponentially increase, relating to the reduction of culture density; at adult stage, the growth speed was even. P. crocea could naturally overwinter at Xiangshan area, Zhejiang Province, and it could reach the marketable size after having been cultured for two years.
