Problems solved by technology

The species of cichlid and green shrimp are different, and there are great differences in their living habits and feeding methods. At present, there are not many studies on the polyculture of cichlid and green shrimp, and the technology of polyculture is immature. The disadvantages of low survival rate and slow growth of lobster and freshwater shrimp reduce the economic benefits of farmers

Abstract

The invention discloses a pond polyculture method for lobster fish and green shrimp. The thickness is 10-15cm; the oxygen-enhancing equipment is equipped; the tea seed cake is used to clear the pond; 5-10 days before the stocking of the lobster fish, water is injected and fertilized; the cultivation area of ​​aquatic plants in the polyculture pond is 25-35% of the total area of ​​the polyculture pond %; 2-4 days before stocking, lay nets in the polyculture pond, and the laying area accounts for 25-35% of the total area of ​​the pond; in late May, stocking lobster, mid-June to mid-July, stocking green shrimp; The green shrimp and the green shrimp are fed separately by using the pellet feed; the water quality is managed; the pond polyculture method of the green shrimp and the green shrimp provided by the invention is simple to operate, and realizes the realization of the green shrimp and the green shrimp. It has high survival rate, fast growth rate, low breeding cost and high economic benefit.

Description

technical field [0001] The invention relates to the field of culture technology, in particular to a method for polyculture of clamfish and freshwater shrimp in ponds. Background technique [0002] Osteophytes belong to Osteostichthyes, Cyprinidae, Cyprinidae, Subfamily Cyprinidae, Osteophytes, and Osteophytes subgenus. They are widely distributed in the Lancang River, Yuan River, Yangtze River, Pearl River and other water systems in my country. They are only seen in Vietnam abroad. of the Red River system. The growth rate of the petaled fish is average. The body length of 1 winter age fish is 19-19.5 cm; the body length of 2 winter age fish is 27.6 cm; the body length of 3 winter age fish is 33.8-34.6 cm; 0.5-1 kg, up to 8 kg, is a large and medium-sized freshwater economic fish in the production area. Freshwater prawns grow fast, have large individuals, reproduce quickly, and have strong vitality. They are widely distributed in freshwater lakes in my country. Their meat is...
