How to raise live seafood?

The first step in feeding seafood is to sort out the dead, seriously injured and sick seafood, and then rinse it clean. If city tap water is used as the water source for raising seafood, it must be dechlorinated before use.

In addition, to maintain the appropriate water temperature. Water temperature is an important factor in seafood preservation. The suitable water temperature of seafood is generally maintained at 18℃-2 1℃, but abalone and mussel are low-temperature and high-salt varieties, and their adaptive temperature is 12℃- 15℃. When the temperature is too high, it is not good for living organisms, and it is easy to cause diseases and losses.

Generally, the dissolved oxygen content in pickled seafood water should be kept above 5 mg/L and below 3 mg/L, which is not suitable for fish survival. Improving water quality, configuring oxygen increasing devices, increasing the number of water changes, reducing the number of storage and breeding, increasing the illumination time, and filtering the water in the temporary pond with water circulation system can all increase the dissolved oxygen content in the water.

Extended data:

1. To raise seafood, it is necessary to improve the water quality at all times, equip with oxygen-increasing devices, increase the number of water changes, reduce the number of storage, increase the lighting time, and use water circulation system to filter the water in temporary storage tanks (tanks and boxes), which can increase the dissolved oxygen content in the water.

2. When raising seafood, the temperature should not be too high. If the temperature is too high, it will be harmful to living organisms and easily cause diseases and losses. When the water temperature is too low, it will affect its survival rate, so try to raise the water temperature.

3. When raising seafood, clean it up and observe it frequently. Clean up dead seafood in water storage tanks (boxes and cans) in time to avoid the deterioration of water quality caused by the decay of dead seafood. Always observe whether the stored seafood has abnormal reaction and whether the water quality is intact. If there is any situation, find out the reason in time and deal with it immediately.
