How long does the sea bass farming cycle generally take?

The farming cycle of sea bass is about half a year. Taking the California sea bass (Micropterus salmoides) as an example, due to differences in individual growth and the habit of cannibalism, in order to ensure the survival rate, timely grading and separate rearing must be carried out according to the actual situation during the rearing process.

In the early stage of farming, grade every 7-10 days with a 5-fen sieve; in the middle stage, grade every 10-15 days with a 7-fen sieve and then move them into No. 6 net cages; rear them until the end of June to early July, grade with a 9-fen sieve and put them into No. 8 net cages for 20-30 days, then grade with a 1.3-cun sieve and put them into No. 10 net cages for grow-out farming.

The farming history of sea bass is relatively short, the farming technology is not yet fully mature, and there is no large-scale fry cultivation base. The fry mainly come from sea capture, with fry being caught in spring. Before farming sea bass, preparations must be made well. Choose a large pond with an area of 6-10 mu; if it is too large it is not easy to manage, and if it is too small the water body is unstable. The water depth must be above 2 m, and it requires an ample water source, clean and pollution-free water quality, and convenient transportation. Before releasing the fry, the pond must be disinfected. First drain the pond water, expose the pond bottom to the sun, then use bleaching powder or lime powder for disinfection and sterilization, keeping the water depth at about 20 cm, soak and splash, and after one week the water can be filled to a depth of 1 m.
