Water temperature control of sea cucumber seedlings under normal temperature

Normal temperature nursery, generally do not need to control the water temperature. However, in the use of pond-reared parental seedlings, in the larval stage of planktonic larval rearing, if the natural water temperature is low, the conditional unit should preferably raise the water temperature to the optimum temperature. Artificial temperature raising seedlings, in the larvae of planktonic larvae, must increase the water temperature.

The incubation temperature can be chosen between 18~20°C. After the cultivation water temperature is determined, it can rise slightly, and it is better not to drop it. If the water temperature drops, you can add high temperature water that is higher than the pool water temperature by 1~2°C when changing the water:

The temperature in the nursery room should be 2~3°C higher than the water temperature. Its role is to prevent the water temperature from falling, and secondly, it does not cause the planktonic larvae to be distributed to the middle and lower layers.
