Culture method of penaeid shrimps in over-winter shed and culture pond thereof

Abstract

The invention relates to a culture method of penaeid shrimps in an over-winter shed, which comprises the following steps: building up a culture pond of the over-winter shed; discharging sea water into the culture pond after treatment, culturing water color of culture water, and then pouring shrimp fries into the culture water for culture; applying a beneficial microorganism preparation during the culture period for degrading pollutants produced during the culture process and conditioning water quality; regulating water temperature of the culture pond by opening small doors at two sides of the shed and opening a plastic thin film; and discharging sewage at the bottom of the culture pond through a central sewage discharge outlet daily and simultaneously supplementing fresh water in the late stage of culture. The culture method of the penaeid shrimps in the over-winter shed can effectively utilize the idle period of the culture pond of the penaeid shrimps in winter, realize the outdoor culture of the penaeid shrimps in winter in the South, ensure the supply of fresh and live penaeid shrimps to the market in low season of the culture and improve the production benefits and the market benefits of the culture; and the culture pond of the over-winter shed for the penaeid shrimps is simple to build up, building materials can be selected according to local material sources, and the plastic thin film and a large-mesh net coat covered on the over-winter shed can ensure that the over-winter shed can realize wind resistance and no leakage of rain.

Description

technical field [0001] The invention relates to the aquaculture industry, in particular to a method for cultivating prawns in an overwintering shed and a culture pond thereof. Background technique [0002] In southern prawn farming, from mid-to-late November to mid-April of the following year, the climate is changeable and the temperature is unstable, causing the outdoor time to exceed 4 months and normal farming cannot be carried out, so the shrimp farming ponds have been idle for at least 100 days , the means of production cannot be rationally utilized, resulting in a waste of resources; in addition, because the current prawn farmers mostly adopt the traditional aquaculture structure for prawn aquaculture production, resulting in no fresh and live shrimps on the market from the end of January to May, and there is not enough shrimp in the market. Supply of fresh and live prawn products. Contents of the invention [0003] The purpose of the present invention is to provide...
