摘要
1996～ 2 0 0 0年 ,先后 4次 5批从日本引进红鳍东方受精卵 5.2 kg(约 30 2万粒 )进行苗种培育试验 ,其中 3次获得成功 ,引进成功率为 75% ,共培育出体长 2 5～ 30 mm的幼鱼 60万尾。受精卵孵化率分别为 50 %、0 %、70 %和 4 0 %。经过 4 2～ 50 d的培育 ,幼鱼培育成活率分别为 64.7%、0 %、4 3.9%和 51.7%。孵化水温为 16～ 18℃ ,幼鱼培育水温为 17～ 2 2℃。试验结果表明 ,引进红鳍东方受精卵进行苗种培育在技术上是可行的。
From 1996 to 2000, 5 2kg(about 3 02 million eggs) Fugu rubripes fertilized eggs have been introduced from Japan by four times to make the experiments of the seedling breeding. Three experiments have obtained remarkable success and the introducing success rate is 75%. 600 000 seedlings which their body length are 25~30mm, have been breeded. The hatching rate of fertilized eggs is 50%, 0%, 70% and 40%, respectively. The survival rate of seedlings is 64 7%, 0%, 43 9% and 51 7% respectively after (42~50days) breeding.The hatching water temperature is 16~18℃ and the seedling breeding water temperature is 17~22℃. Experiments show that it is feasible to breed seedling with the introducing fertilized eggs of Fugu rubripes.
