摘要
在人工养殖条件下 ,研究大海马 (HippocampuskudaBleeker)幼鱼的生长特性及其成活率。结果表明 ,大海马幼鱼的最大增长率为 1 5 88% ,最大增重率为 52 94% ,最小增长率为 2 80 % ,最小增重率为 8 0 5 % ,群体增重倍数为 7 2 0 ,幼鱼的平均日增长率和日增重率分别为 0 44mm/d和0 0 0 5 2g/d。大海马幼鱼体长与日龄的关系式为L =1 5 2 8+0 40 6 5T ,体重与日龄的关系式为W=1 865× 1 0 -4 T1 6872 ,体重与体长的关系式为W =6 884× 1 0 -6L2 762 2 。大海马幼鱼的成活率为90 4%。
The growth characteristic and survival rate of larval seahor se, Hippocampus kuda Bleeker, were discussed under industrial culture condition. The results sho wed that the maximum growth rate of body length and growth rate of body weight of larv al H.kuda were 15 88% and 52 94% respectively, the minimum were 2 80% an d 8 05% respectively, the population body weight increased by 7 20 times The average g rowth rates of body length and weight were 0 44mm/d and 0 005 2 g/d respective ly T he formula about body length and time (days) was L=15 28+0 406 5 T T he formula ab out body weight and time(days) was W=1 865×10 -4 T 1 687 2 .Th e formula about body l ength and body weight was W=6 884×10 -6 L 2 762 2 .The surviv al rate of larval H.kuda was 90 4%.
