The suitable water temperature for life is15 ~ 32℃, but some scholars have shown that within the range of10 ~ 25℃, the specific growth rate of Siniperca chuatsi increases with the increase of temperature, but there is no obvious change between 25 ~ 35℃. When the water temperature reaches 35℃, the specific growth rate of Siniperca chuatsi increases.

That is to say, in a certain temperature range, the feeding rate and growth rate of fish increase with the increase of water temperature. When the water temperature exceeds the optimum water temperature, the feeding rate and growth rate of fish will decrease inconsistently, which indicates that the optimum growth temperature of Siniperca chuatsi may be wider.

Extended data:

The breeding season of Siniperca chuatsi is from mid-May to early June in the Yangtze River valley of China, from April to August in South China and from mid-June to late July in Heilongjiang River valley.

Under natural conditions, the spawning ground of Siniperca chuatsi is usually at the inlet of a lake with a certain flow rate and the beach with wind and waves, and the spawning activity is the most prosperous at night when the water rises after rain.

The spawning ground of Siniperca chuatsi in Poyang Lake is distributed in the coastal area between Hukou and Xingzi. The spawning ground has a water depth of1~ 2m, a flow velocity of 0.6 ~ 0.8m/s, sandy bottom and a water temperature of about 23℃. Before spawning, the parent fish of Siniperca chuatsi showed the characteristics of clustering. When spawning, sexually mature Siniperca chuatsi swam and chased in pairs on the water surface, and then laid eggs and discharged sperm in batches in the lower layer of the water body.
