A feeding method for dispersing leech seedling colony

Abstract

The invention discloses a feeding method for dispersing leech seedlings living in groups. The method of the invention uses small field snails in rural seedling fields as seedling feed for leech seedlings, which solves the serious problem of seedlings living in groups and climbing heaps in the past, because no food can be obtained. The situation of serious death caused by this method is simple and feasible, and its advantages have changed the phenomenon that the traditional paste feeding pollutes the water quality and causes serious casualties. The rate is extremely low, and no one in China has used this method. This will fundamentally solve the worries of seedlings living in groups without smoking and dying seriously in the future breeding process for the majority of breeding enthusiasts, and can be widely used in breeding enterprises and Application and development of farmers in production.

Description

technical field [0001] The invention belongs to a breeding technology, in particular to a feeding method for dispersing leech seedlings living in groups. Background technique [0002] Many areas in our country are engaged in leech breeding and production, and the development is slow. The root of the problem is that during the seedling feeding period, the mortality rate is extremely high, and the survival rate is less than 30%. This phenomenon is a living habit that it cannot change. The traditional method of feeding seedlings is to use river mussels and snails to crush the meat paste and add other ingredients. After entering the water, they will all live in groups on the surrounding pool walls for about one minute. They can rely on their own yolk to maintain their lives within three days. Feeding seedlings with processed meat paste is not only labor-intensive and time-consuming, but also seriously pollutes water quality. As soon as the temperature rises, the water body wil...

Problems solved by technology

The traditional method of feeding seedlings is to use river mussels and snails to crush the meat paste and add other ingredients. After entering the water, they will all live in groups on the surrounding pool walls for about one minute. They can rely on their own yolk to maintain their lives within three days. Feeding the seedlings with processed meat paste is not only labor-intensive and time-consuming, but also seriously pollutes the water quality. When the temperature rises, the water body will turn green and black. If the water is not replaced in time, the young leeches will die soon.
