Problems solved by technology

However, during the pond cultivation process, it was found that the seedlings had obvious growth differences and the catch rate was low, which affected the production of large-scale summer flowers (about 5cm or more)

Abstract

The invention relates to a method of odontobutis potamophila cultivation. The method comprises the following steps of 1, constructing an ecological cultivation model; 2, specifically managing cultivation, fishing up surplus aquatic plants, and ensuring the water face coverage area less than or equal to 80%; in order to control water quality reasonably, feeding freshwater shrimps with feed once every 1-2 days, detecting the water quality once every 5-7 days, changing 1 / 4- 1 / 2 of water quantity every 2-4 days and carrying out sewage absorption treatment. According to the method of the odontobutis potamophila cultivation, the scheme of same pond fresh water shrimp and odontobutis potamophila cultivation is adopted, feeding the freshwater shrimps with the feed to make the odontobutis potamophila catch and feed on the freshwater shrimps, and the problem of labor intensity of farmers is effectively solved; according to the method of the odontobutis potamophila cultivation, pipe fittings and the aquatic plants are arranged, the condition of intraspecific feeding competition is effectively alleviated; the specification size of the freshwater shrimp and the specification size of the odontobutis potamophila are maintained in a proper range, not only is interspecific competition avoided, but also unreasonable interspecific feeding competition is avoided.

Description

technical field [0001] The invention relates to a method for cultivating fish, in particular to a method for cultivating river snakeheads. Background technique [0002] Odontobutis potamophila (Odontobutis potamophila), commonly known as Tubu fish and Tangwu snakehead, is a small bottom wild freshwater fish. Under natural conditions, it lives in rivers, lake bottoms or near-shore aquatic plants and gravel. Small fish and crustaceans are the main species. Staple food, mainly distributed in the Yangtze River, Pearl River, Qiantang River and Minjiang River and other water systems. Because of its delicious meat, it is very popular among consumers. Considering the increasing shortage of natural resources of S. chinensis in rivers, in recent years, the Zhejiang Freshwater Fisheries Research Institute has established a mature breeding system for broodstock, egg protection for male fish, and pond seedlings through the observation of the reproductive characteristics of S. chinensis ...
