1, bait feeding: the bait is mainly fresh small miscellaneous fish, preferably live bait, and cut into blocks with appropriate size according to the specifications of the fish species for feeding. When feeding, quantitative feeding is adopted, which generally accounts for10 ~15% of the fish weight in the early stage and 5 ~10% in the later stage. The best feeding time is 5 ~ 6 am and 7 ~ 8 pm.

2. Reasonable polyculture: In order to save the cost, white shrimp can be put into the water for culturing the fish, or tilapia can be polycultured with summer flowers. The residual bait and feces of the fish are used as bait for the white shrimp and tilapia, while the white shrimp and tilapia are high-quality bait for the fish, so as to balance the ecology of the fish pond.

Precautions:

1, the protein content in the muscle of wild Leptospira is 16.62%, the fat is 2.66%, the moisture is 80.73%, and the ash is 0.92%. The protein content in the muscle of the cultured Haliotis diversicolor is 16.5 1%, the fat is 2.5 1%, the water content is 80.65%, and the ash content is 0.94%.

2. The contents of water, protein and fat in wild Leptospira are slightly higher than those in cultured Leptospira. * * * 17 amino acids were detected, including 8 essential amino acids and 4 flavor amino acids. The total amount of amino acids in wild group was significantly higher than that in cultured group.

3. The total amount of essential amino acids is also higher than that of the culture group. Compared with the cultured fish, the content of threonine, leucine and sulfur-containing amino acids in the muscle of wild fish is higher. Based on the amino acid score, lysine is the first limiting amino acid and valine is the second limiting amino acid.
