Bait additive for preventing parasitic caligus of bostrichthys sinensis cultured in seawater pond

Abstract

The invention provides a bait additive for preventing parasitic caligus of bostrichthys sinensis cultured in a seawater pond. A first kind of additive consists of garlic paste accounting for 1 to 3 percent of the bait weight and a multi-vitamin mixture accounting for 2 to 4 percent of the bait weight; and a second kind of additive consists of garlicin accounting for 0.2 to 0.6 percent of the bait weight and a multi-vitamin mixture accounting for 2 to 4 percent of the bait weight. Sharp taste of the two additives can prevent the caligus from adhering in oral cavities of the bostrichthys sinensis and can also repel the caligus which adheres inside the oral cavity but is not eaten by the sick fish, so that an anti-stress capacity of the sick fish can be enhanced, and the inflammation diminishing and healing of wound of the oral cavity after the caligus is split can be promoted. The bait additive also has an action on improving the appetite of the bostrichthys sinensis.

Description

technical field [0001] The invention relates to a bait additive, in particular to a bait additive for preventing and treating the parasitic sticklebacks of snakehead carp in seawater ponds. Background technique [0002] Bostrichthys sinesis (Lacepède) is a high-quality and high-value marine fish cultured in seawater ponds in the southern coastal provinces of my country. As a fresh food on people's tables, it is not only delicious, but also has high nutritional value. However, during the breeding process, many parasitic crustaceans called fish lice Caligus sp are often parasitized in the mouth and jaw. This kind of fish lice not only eats the tissues of the snakehead snakehead, sucks its body fluids and blood and other nutrients, but also stimulates the fish body to produce a stress response, which seriously affects the fish's feeding and life, and eventually causes the diseased fish to fail and die in batches. Because the parasite lives in the oral cavity of Channa sinensi...

Problems solved by technology

Because the parasite lives in the oral cavity of Channa sinensis, the current routine control method of splashing crystal trichlorfon solution not only affects the quality and safety of its products to a certain extent, but also has poor killing effect; if the splashed crystal trichlorfon solution Increase the concentration of worms to the concentration that can kill the fish lice in the mouth of the fish, which will cause the death of the cultured snakehead
