Method for breeding Odontobutis obscura through fish-rice symbiosis in pool

Abstract

The invention relates to a method for aquaculture, in particular to a method for breeding Odontobutis obscura through fish-rice symbiosis in a pool. According to the method, rice is planted in the pool for Odontobutis obscura aquaculture. The fish-rice symbiosis method is adopted for breeding food organisms in water to provide natural baits for fishes, and the rice is used for providing ingestion, shielding and inhabiting space for the fishes, shrimps, crabs and others; the fishes and the crabs prey on insect pests to control ineffective tillering of the rice; original ecology planting mode that no pesticide is sprayed, no fertilizer is applied, and residual baits and excrement are used as nutrients is adopted, , so that while the problem of nutrient enrichment of aquaculture water is effectively solved, shading and cooling are achieved in summer; heat preservation and temperature constancy are achieved in winter, an inhabiting place is provided for the bred variety, the growth period is prolonged, so that the breeding yield and quality and the specification on the market are improved, and the high yield and efficiency are achieved. According to the method, the production problem that wild and natural prey of the Odontobutis obscura is converted into artificial breeding is solved, the environment of breeding water quality, apparent availability and breeding production benefits are improved, and the method is of great importance in protecting natural resources.

Description

technical field [0001] The invention relates to an aquaculture method. Background technique [0002] Pond snakehead fish, scientific name river sand pond snakehead ( Odontoburis obscura ), is a small carnivorous economic fish. It is popular among consumers for its no spines, no fishy smell, and delicious meat. It is known as "the first dish of Shanghai World Expo". Due to the pollution of the water environment and the excessive fishing of people, the wild pond snakehead is decreasing day by day, and the market price is constantly pushing up. However, the pond snakehead is a small carnivorous bottom fish that requires to live in water with fresh water quality and high dissolved oxygen. It swims slowly and adopts ambush feeding methods. It is difficult to obtain high yields in the traditional high-density pond breeding mode. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a meth...
