美国红鱼(Sciaenops ocellatus)的鱼苗特性及苗种运输技术

美国红鱼的鱼苗阶段以轮虫和卤虫为主要饵料，鱼苗生长迅速，孵化后约25d即为体长3．0cm左右的幼鱼．对体长2．0～7.0cm鱼苗的运输试验结果表明，美国红鱼苗对长时间运输的耐受力较强．在水温24℃以下，尼龙袋和帆布桶运输10h以内的运输成活率均在94％以上．引起鱼苗死亡的临界DO为2．2mg／L.

STUDY ON FRY CHARACTERISTICS AND TRANSPORT TECHNOLOGY OF SEEDLING OF AMERICAN RED

Fry of Atnrican red fish(ScItienoPs occllatus)talce Rotifer and ArteAna as primary foods.The fry grows fast and bec0me y0ung with t0tal lengil1 0f ab0ut 3.0 cm after 25 d of hatChing. The transport exPeriment 0f fry with 2.O-7.O cm sh0ws that fry of Ainerican red fish has quite good endurance for long-distance trdrispor tahon. Under the c0ndihon of temperature under 24 t, the survival rate of transportahon of nylon bag iuld canvas bucket are both greater than 94% in l0 hrs. The crihcal 1evel of dissolved oxygen concentrtlhon is about 2.2 mg/L.
