Problems solved by technology

In the existing grass carp breeding methods, no attention is paid to the breeding process of grass carp fingerlings, and the lack of scientific fish fingerling breeding management will easily lead to a decrease in the growth rate of grass carp, and it is difficult to ensure the production of commercial fish in the year, and the annual output is unstable

Abstract

The invention provides a grass carp cultivation method comprising the following steps: (1) fry cultivation is carried out, namely grass carp fries are added into a cultivation pond, and are cultivated into fingerlings; (2) fingerling cultivation is carried out, namely the grass carp fingerlings are cultivated until an average mass of the fingerling reaches 500-1000g per fingerling; (3) adult fish cultivation is carried out, namely broad beans are used for feeding the grass carp fingerlings twice per day until the grass carp fingerlings grow into adult grass carps; and the adult grass carps with an average mass of 1000-3000g per carp can be caught and marketed. The grass carp cultivation technology provided by the invention has high efficiency, and assists in effectively improving grass carp annual yield and reducing feeding cost. Also, with the method, the adult grass carps have robust body constitution, good shape, compact meat and rich nutrients. The method meets the requirements of ecological fishery development.

Description

technical field [0001] The invention relates to the technical field of cultivation, in particular to a grass carp cultivation method. Background technique [0002] Grass carp belongs to Cyprinidae in classification. Commonly known as: carp. Because of its fast growth rate, short food chain, delicious meat, rich and comprehensive nutrition, and good economic benefits, it is widely welcomed by people. [0003] Grass carp is the fish with the second largest aquaculture output in the world, second only to silver carp. It is widely distributed in the Pacific and Indian Oceans, mainly in Southeast Asian coastal countries such as China, North Korea, Thailand, and the Philippines. my country has the largest grass carp resources in China. my country is distributed in the rivers and rivers in the northeast, east, central and southern regions. In recent decades, grass carp has been introduced to various parts of the world, such as Japan, Southeast Asia, Eastern Europe, and the United...
