Feeding method for dispersing gregarious leech larvae

Abstract

The invention discloses a feeding method for dispersing gregarious leech larvae. According to the method, small paludina in rural rice fields is adopted as a larva support feed of leech larvae, so that the condition of severe death caused by that fact that in the past, gregarious and clustered phenomena of the larvae are serious and the feed cannot be taken is solved thoroughly. The method has a simple and practical technology, and has the advantages that the phenomena of water pollution and severe deaths due to traditional paste feeding are changed, meanwhile, the small nutrient paludina is adopted to feed the leech larvae, and particularly, the leeches have good liveness, grow fast and are extremely low in death rate; and the method is not used by anyone domestically, the worries that the gregarious leeches do not eat and the death is severe are solved thoroughly during the future cultivation process of wide cultivation lovers, and the method can be widely applied to application and development by cultivation enterprises and 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...

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.
