Method for preventing and treating leukoderma of prawn

Abstract

The invention relates to a method for preventing prawn leukoderma, which is characterized by adding 0.1-0.2 wt% of gulfweed polysaccharide extract to the foodstuff of prawns. By adopting the method to cultivate prawns, non-specific immune system is stimulated, thus strengthening the immunity and resistance of prawns, obviously enhancing the immune function of prawns, and does not generate adverse influence on the palatability of foodstuff and has significant effect on the prevention of prawn leukoderma. The method has stable source of gulfweed, simplified production technology and significant effect.

Description

technical field The invention belongs to a method for preventing and treating white spot disease of prawns. Background technique With the expansion of the scale of prawn farming, people pay more and more attention to the research on the prevention and control of its diseases, among which the research on the immune function of prawns has attracted more and more attention. Studies have shown that shrimp is a crustacean, and its immune mechanism is mainly non-specific immune response. Antimicrobial factors are mainly various enzymes in hemolymph, which include lysozyme, acid phosphatase, phenoloxidase, superoxide enzymes, etc. In its open circulatory system, the prophenoloxidase activation system plays an important role in foreign body recognition and immune defense. One of the keys to prevent and treat shrimp diseases is to improve the immunity of shrimp itself. However, there are problems such as the abuse of antibiotics, hormones and some carcinogenic chemical compounds in...
