Feed additive for improving prawn immune activity, feed and culture method

Abstract

The invention provides a feed additive for improving the prawn immune activity, feed and a culture method. The feed additive comprises, by weight, 10-30 parts of copepods, 10-30 parts of opossum shrimp and 50-70 parts of kelp powder. The copepods, the opossum shrimp and the kelp powder are added into the feed additive, and the copepods and the opossum shrimp have rich flavour amino acid and unsaturated fatty acid and are good phagostimulant for prawn. The active ingredients in the copepods, the opossum shrimp and the kelp powder can remarkably improve prawn immunity and promote prawn growth and improve prawn survival rate, the good economic benefits and social benefits are obtained, prawn culture sustainable development is facilitated, and the feed additive accords with the aquatic feed development tendency.

Description

technical field [0001] The invention belongs to the field of prawn cultivation, and in particular relates to a feed additive for improving the immune activity of prawns, a feed and a cultivation method. Background technique [0002] With the rapid development of the shrimp farming industry and the continuous improvement of intensive farming, the disease problem has become increasingly prominent. In the traditional disease control methods, antibiotics and chemical drugs are regarded as the main means and are used in large quantities in farming, resulting in the emergence of pathogens. Drug resistance reduces the therapeutic effect; at the same time, due to drug residues, it seriously affects the health of consumers and the safety of the ecological environment. Due to the excessive drug residues in aquatic products, the export of aquatic products is hindered, which seriously affects the competitiveness of my country's aquatic products, hinders the development of domestic and f...

[0002] With the rapid development of the shrimp farming industry and the continuous improvement of intensive farming, the disease problem has become increasingly prominent. In the traditional disease control methods, antibiotics and chemical drugs are regarded as the main means and are used in large quantities in farming, resulting in the emergence of pathogens. Drug resistance reduces the therapeutic effect; at the same time, due to drug residues, it seriously affects the health of consumers and the safety of the ecological environment

Due to the excessive drug residues in aquatic products, the export of aquatic products is blocked, which seriously affects the competitiveness of my country's aquatic products, hinders the development of domestic and foreign markets, and causes huge economic losses.
