采用牡蛎受精卵—轮虫—丰年虫幼体—桡足类—鱼肉糜育苗饵料系列,双棘黄姑鱼的育苗水温为23.5℃以上,2003年出苗全长4.11 cm鱼苗12万尾;2004年出苗全长2.7 cm鱼苗8万尾;2005年出苗全长3.41 cm鱼苗33.7万尾,2005年育苗单位水体出苗率为3 510尾/m3,育苗成活率为41.6%。双棘黄姑鱼苗的特点为前期生长很慢而15日龄后生长极快,全长1.0 cm开始出现严重的自相残杀现象。
The oyster fertilized eggs - rotifers - Artemia larvae - copepods - fish culture and fish feed bait series, double yellow croaker fish nursery water temperature of 23.5 ℃ or more, in 2003 the total length of 4.11 cm fry 120 000; 2004 emergence The total length of 2.7 cm fry is 80,000. In 2005, the total length of the fry is 3.37 cm with the total length of 3.41 cm. In 2005, the seedling emergence rate was 3 510 fish per m3, and the survival rate of the breeding seedlings was 41.6%. The characteristic of double spike yellow kufu fry is that its growth is very slow in the early stage, and its growth is very fast after 15 days of age. The full-length 1.0 cm begins to appear the serious fratricidal killing phenomenon.
