Compound preparation for killing wild fish and snail and preparation method

Abstract

The invention provides a compound preparation for killing wild fish and snail and a preparation method thereof; the compound preparation for killing the wild fish and the snail comprises the following components by weight parts: 40 to 50 parts of tea saponin, 60 to 80 parts of areca, 40 to 60 parts of niclosamide and 30 to 40 parts of zeolite powder; the preparation method uniformly stirs the raw material tea saponin, areca, niclosamide and zeolite powder by weight parts; the compound preparation for killing wild fish and snail promotes the dysfunction and the death of all organs and systems of the wild fish and the snail through the cooperation of the tea saponin, the areca and the niclosamide, has the advantages of strong killing effect and safety to shrimps and crabs, and effectively prevents the situations that the wild fish, the snail and the like fight over bait, nutrition, space and the like with the shrimps, the crabs and the like; and the preparation method is simple, and is applicable to the needs of scale industrial production.

Description

Technical field [0001] The invention relates to a product for killing wild fish and snails and a preparation method thereof, in particular to a compound preparation for killing wild fish and snails and a preparation method thereof. Background technique [0002] When stocking shrimp and crab fry every year, some wild fish will inevitably be mixed in. In addition, wild fish may enter shrimp and crab ponds during the process of water intake and water change, and the ponds will reproduce during the breeding process. Some snails, these wild trash fish and snails will compete with shrimps and crabs for feed, reduce feed utilization, and affect the growth of shrimps and crabs. In the past, wild fish in shrimp and crab ponds were often killed by sodium pentachlorophenate, but sodium pentachlorophenate is highly toxic and has serious environmental pollution. The country has banned its use. Therefore, it has developed a method that can effectively kill wild fish and The preparation of sna...

Problems solved by technology

[0002] Every year when shrimp and crab seedlings are put in, some wild fish will inevitably be mixed in. In addition, wild fish may also enter the shrimp and crab ponds during the process of water intake and water change, and the ponds will reproduce during the breeding process Some snails, these wild fish and snails will compete with shrimp and crabs for feed, reducing feed utilization and affecting the growth of shrimp and crabs

In the past, sodium pentachlorophenate was commonly used to kill wild fish in shrimp and crab ponds, but sodium pentachlorophenate is highly toxic and pollutes the environment seriously. The preparation of snails is of great practical significance
