Embodiment 1

[0021] A bait additive for preventing and controlling Litopenaeus vannamei hepatica, comprising the following components by weight: 32g of marine rhodotorula powder, 30g of albendazole, 32g of spirulina powder and 5g of garlic powder.

[0022] The above-mentioned various raw materials are made into 100-mesh fine powder, and mixed evenly to obtain the bait additive for preventing and treating Litopenaeus vannamei hepatica. The bait additive for preventing and controlling Litopenaeus vannamei hepatica can be added in an amount of 6-12% by weight in the prawn feed, and can also be mixed with the feed before feeding according to the weight ratio of 1:10.

Embodiment 2

[0024] Referring to the preparation process in Example 1, multiple groups of compound bait additives were prepared. The specific formulations are shown in Table 1, and the amounts of all raw materials in Table 1 are in grams.

Abstract

The present invention discloses a medicinal bait additive for preventing and treating enterocytozoon hepatopenaei of litopenaeus vannamei. The medicinal bait additive comprises the following components in parts by weight: 8-32 parts of marine red yeast powder, 30-75 parts of albendazole, 8-32 parts of spirulina powder and 5-10 parts of garlic powder. The medicinal bait additive is used in a compound feed for the litopenaeus vannamei and has an addition amount of only 6-12%; and the medicinal bait additive can also be mixed with the feed at a weight ratio of 1:10 for feeding before feeding. Themedicinal bait additive uses an internal administration route, so that a medicine internal environment is formed in a host body, the medicinal bait additive is subjected to blood circulation to reachtarget organs and parasites cannot survive. The medicinal bait additive can effectively kill the enterocytozoon hepatopenaei in the litopenaeus vannamei body, is non-toxic to the litopenaeus vannameibody, does not cause medicine residues in the litopenaeus vannamei body, at the same time also does not cause pollution to the breeding environment, and can effectively play a therapeutic role in thediseased litopenaeus vannamei infected by the enterocytozoon hepatopenaei.

Description

technical field [0001] The invention belongs to the technical field of mariculture disease prevention and control, and in particular relates to a bait additive for preventing and treating Enterocystis hepatica of Litopenaeus vannamei. [0002] Background technique: [0003] Litopenaeus vannamei is one of the three largest shrimp species with the highest aquaculture production in the world today. With the continuous improvement of the degree of intensification of breeding, the threat of various diseases to its breeding is also increasing day by day. Enterocytozoon hepatopenaei (EHP) is a microsporidia found in prawns in recent years, mainly infecting important cultured shrimps such as Litopenaeus vannamei and Penaeus monodon. The most obvious feature of Litopenaeus vannamei infection is that the growth rate will become very slow, the individual differences of the prawns are large, and the appetite of the cultured prawns is normal but they do not grow in size, causing huge eco...
