Ietalurus punetaus breeding method

Abstract

The invention discloses an ictalurus punetaus breeding method. The ictalurus punetaus breeding method comprises the following steps: (1) parent fish breeding; (2) fish pond treatment; (3) fish fry culture; (4) intercropping of plagiognathops microlepis fingerlings; and (5) adult fish management, namely a, mixing of poison bait; b, saprolegniasis prevention and control; c, control of ammonia poisoning; and d, water conversion first aid. According to the ictalurus punetaus breeding method, a systematized and scientific whole-process breeding method is provided from parent fish breeding of ictalurus punetaus, fish fry culture to later adult fish management. Compared with an existing breeding method, the systematized and scientific whole-process breeding method has the advantages that overall planning is realized on the breeding cycle and investment of labor and materials. The breeding method has high breeding density, enables the ictalurus punetaus to grow fast, has excellent response on diseases and emergency situations, and has remarkable social benefits and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to a method for cultivating channel catfish. Background technique [0002] Channel catfish (Ictalurus punctatus), native to the Americas, belongs to Siluriformes and Cateridae, also known as channel catfish. It has the characteristics of fast growth, wide temperature range, and strong disease resistance. Low, suitable for intensive and large-scale farming. Channel catfish is tender, delicious, rich in protein and unsaturated fatty acids, and is deeply loved by consumers in the United States, the European Union and other countries. However, due to its low local production, most of the demand depends on imports. Therefore, the large-scale cultivation of channel catfish in my country The prospect is promising. After several years of research and promotion of breeding, it has been confirmed that this fish is suitable for breeding in most areas of China. In recent years...

Problems solved by technology

[0003] In the channel catfish intensive culture mode, high stocking density is the basis for obtaining high breeding returns. However, there are many shortcomings in the current breeding methods, including unstable breeding yield, low yield, weak seedlings, and the growth period. There are no effective preventive measures for the disease, which restricts the further improvement and industrialization of the channel catfish breeding level
