Embodiment 1

[0017] (1) Cedar tabby with leeches parasitized, according to 240kg / 15m 3 density, cultured in an area of ​​15m 2 , in a cement pool with a water depth of 1m, drain to a water depth of about 30cm, add 40g of copper sulfate and ferrous sulfate powder, and soak for 20 minutes;

[0018] (2) Add 10ml of 1% abamectin and soak for 60 minutes;

[0019] (3) After changing all the water, add 7g of multi-component organic acid antidote for detoxification. The selected multi-component organic acid antidote is Bishuian produced by Liyang Aquatic Products;

[0020] (4) Observe carefully, on the 6th day after killing insects, when the remaining eggs in the pond have just developed into adults visible to the naked eye, repeat the above steps 1-3.

Embodiment 2

[0022] (1) Cedar tabby parasitized with leech, according to 250kg / 15m 3 density, cultured in an area of ​​15m 2 , in a cement pool with a water depth of 1m, drain to a water depth of about 30cm, add 50g of copper sulfate and ferrous sulfate powder, and soak for 18 minutes;

[0023] (2) Add 20ml of 1% abamectin and soak for 50 minutes;

[0024] (3) After changing all the water, add 11g of multi-component organic acid antidote for detoxification. The selected multi-component organic acid antidote is Bishuian produced by Liyang Aquatic Products;

[0025] (4) Observe carefully. On the 7th day after killing insects, when the remaining eggs in the pond have just developed into adults visible to the naked eye, repeat the above steps 1-3.

[0026] According to the method described in Example 1-2, the fir tabby is processed, and the leeches adsorbed on the fir tabby basically all fall off and die, and only a few sporadic leeches parasitize in the later stage of cultivation, which wil...

Abstract

The invention discloses a method for removing parasitic fish leeches of hybrid of flowery grouper and tiger grouper. The method mainly comprises the following steps: adding 40-50 g of copper sulfate ferrous sulfate powder into a cement pond with the area of 15m <2> and the water depth of 1 m, wherein the cement pond is bred with the hybrid of flowery grouper and tiger grouper with the total mass of 240-250 kg, and soaking for 18-20 minutes; adding 10-20 ml of abamectin for soaking for 50-60 minutes; adding 7-11g of a polybasic organic acid antidote to detoxify after water is changed thoroughly; and repeating the foregoing step (1) to step (3) 6-7 days later. According to the method, Cu2+ in the copper sulfate ferrous sulfate powder can be combined with protein to form a chelate, so that the protein is denatured and precipitated, so that enzyme in the parasitic fish leeches on the hybrid of flowery grouper and tiger grouper is inactivated, meanwhile, the ferrous sulfate has a convergenteffect and assists in killing insects, the abamectin stimulates and releases Y-aminobutyric acid by interfering the neurophysiological activity of the fish leeches, and the fish leeches can have paralysis symptoms after being in contact with the abamectin, and do not move or eat food until death. The problem of repeated outbreak of the fish leech disease can be solved when residual eggs do not develop into mature adults capable of laying eggs repeatedly.

Description

technical field [0001] The invention relates to a method for removing parasitic fish leech from fir tabby, belonging to the field of aquaculture. Background technique [0002] The fir tabby is a hybrid of male and female fir tabby. Compared with the tiger tabby, the fir tabby is more adaptable to the environment, resistant to transportation, and has delicious meat. It enters the market as a high-end fish with considerable profits. [0003] Leeches, commonly known as seawater leeches, soil worms, black worms, etc., are ectoparasites in grouper culture, mainly parasitic on the pectoral fins and bases of pectoral fins of grouper fish, and secondly parasitic on the head, On the dorsal and caudal fins, there are also cases of parasitism on the eyes of groupers. The rapid reproduction speed of leeches will cause the grouper to rot, become thin, malnourished, and seriously reduce production. It is also the medium for the transmission of blood bacteria, viruses, parasites and other...
