Cage raising method for rice-field eel offspring seeds

Abstract

The invention discloses a cage raising method for rice-field eel offspring seeds, and aims to provide a cage raising method for the rice-field eel offspring seeds based on the conventional rice-field eel breeding method with an innovative scientific principle. By adopting the cage raising method, labor force is saved greatly, the death rate of the rice-field eels is lowered, the yield of the rice-field eels is increased, and the aims of high yield and high quality are fulfilled. The method comprises five steps in total.

Description

technical field [0001] The invention belongs to the technical field of cultivation, and relates to a cultivation method, in particular to a method for cultivating ricefield eel seedlings in cages. Background technique [0002] Eels, also known as field eels, have no scales. The back and anal fins are very low and continuous around the tail. The gills usually have only one external gill opening at the throat. They are often kept in ponds or rice fields. The body is slender and snake-shaped. The round rear part is flat, the tail is pointed and thin, and the body is mostly yellow-brown, slightly yellow or orange-yellow in life, with dark gray spots. Eel is a tropical and warm-temperate fish with strong adaptability. It can be found in rivers, lakes, ditches and rice fields. It can survive in the middle of the world. It likes to drill holes in the humus silt during the day or live in caves in the stone crevices with water on the embankment. It rarely moves. As an auxiliary orga...

Problems solved by technology

The wild eel resources are limited. With the improvement of people's living conditions, the demand for eels has risen sharply. Wild fishing is difficult to meet the needs of farms. This requires large-scale artificial breeding of rice field eels.

Since the artificial breeding of eel has not been completed, all eel species are caught in the wild. Wild eels live in the natural state for a long time, and mainly feed on aquatic animals and plankton that are rich in live fish, live shrimp, python mussels, and water maggots. It is difficult to achieve these conditions in artificial large-scale breeding, so it is necessary to domesticate the eel to eat artificial compound feed. It is difficult for the eel to adapt to the environment when it is raised in the cage, and it takes a long time to adapt to the changes slowly. Domestication of the eel artificial compound feed also requires Time, so it is difficult for small eel species to reach the market specifications in the first year, and they must be bred in the second year before they can be marketed
