| 摘 要： | 在室内水族箱中养殖地图鱼的幼鱼,密度分别为50、100、200、400尾/m2,共养殖28d。试验结果表明,各密度组地图鱼幼鱼的生长速度存在明显差异,增重率、增长率、特定生长率和平均日增重都随养殖密度的增加而降低;高密度组(400、200尾/m2)地图鱼的幼鱼个体生长速度离散度明显加大。

| Abstract: | Juvenile Astronotus ocellatus were stocked and reared in an indoor tank at a rate of 50, 100, 200 and 400 individuals/m~2 for 28 days. The results showed that there were significant decreases in length increment, special growth rate and daily weight gain of the juveniles with the increase in stocking density increase. The fish in high-density groups (200 and 400 fish/ m~2) had great variation in size and growth. |
