Method for ecologically breeding macrobrachium nipponensis and Odontobutis obscura in pond by utilizing artificial ecological base

Abstract

The invention discloses an application method for ecologically breeding macrobrachium nipponensis and Odontobutis obscura in a pond by utilizing an artificial ecological base. The method comprises the following steps of (1) pond selection; (2) forming of pond artificial ecological base layout and biological film; (3) fry stocking; (4) feedstuff feeding; (5) water quality regulation and control and daily management; (6) fishing of grown macrobrachium nipponensis and grown Odontobutis obscura. Compared with the prior art, according to the method, the water quality of the pond can be kept good and stable, water does not need to be replaced in the whole breeding period except in the season with higher water temperature, new water is added to increase the water level, no breeding wastewater is drained, and the ecological benefits are obvious; the biocenosis such as microorganisms and algae on the ecological base can provide the suitable habitat for shrimp seeds and the Odontobutis obscura; the Odontobutis obscura is utilized for catching and feeding on the weak and sick shrimp seeds and autumn seeds bred in august; the breeding disease rate of the macrobrachium nipponensis is reduced; the out-of-pond specification and yield of the grown macrobrachium nipponensis are improved, and the economic benefits are obvious.

Description

technical field [0001] The invention belongs to the technical field of aquatic product ecological cultivation, and mainly relates to an application method of an artificial ecological base in pond ecological cultivation of Macrobrachium japonicus and snakehead snakehead. Background technique [0002] Japanese giant river prawn (Macrobrachium nipponense) is delicious and has high nutritional value. The price remains high and the market is in short supply. Its aquaculture industry has become one of the important industries in freshwater aquaculture in my country. By 2012, its aquaculture output has reached 237,400 tons . However, under the traditional breeding mode, the shrimp seedlings stocked in summer began to reproduce in large numbers at the end of August, resulting in mixed generations, resulting in a decline in aquaculture production and quality, germplasm degradation, and frequent occurrence of diseases, etc., which slowed the development of Macrobrachium japonicus aquac...

AI Technical Summary

Problems solved by technology

Artificial ecological bases have been widely used in the restoration of eutrophic water bodies at home and abroad, but they are rarely used in aquaculture. So far, there have been no technical reports on the application of artificial ecological bases in pond culture of Macrobrachium japonica
