Four series of experiments had conducted to study the influence of diferrent temperatures on the growth, the first two were conducted in laboratory and the others in fishing farm. The total observed fishes counted 370.1. The optimum temperature for growth is at 28-30℃. From 22℃ to 28℃ the growth rate is increased, while from 32℃ to 36℃, it is decreased, and at 36℃ it is stopped.2. The determined optimum temperature for growth in winter is lower (28℃,Tab. 1,2) than that in summer (30-3213, Tab. 4, 5, 6). The...
