Industrial and three-crops a year type prown cutturing method and pond therefor

Abstract

An industrial culture method for prawn includes such steps as arranging the serially connected high-level culture pool and low-level culture pool, culturing the young prawn in the high-level culture pool for 30-50 days, and culturing in the low-level culture pool. Its culture pool system is composed of a primary high-level culture pool, a secondary low-level culture pool, transfer pipeline, and two drain pipes. It can output prawn three times in one year.

Description

technical field [0001] The invention relates to a method for three crops of industrialized prawn cultivation, and also relates to a culture pond with high and low positions connected in series used in the cultivation method. Background technique [0002] At present, the single-pond structure is usually adopted in the cultivation process of prawns. Generally, one crop is cultivated in a year, and at most two crops are cultivated. As a result, the shrimp ponds are idle for at least 100 days during the time suitable for prawn farming, resulting in the lack of reasonable use of production materials. The resources used are wasted; in addition, because the current prawn farmers mostly adopt the above-mentioned traditional aquaculture structure to produce prawns, most of the finished prawns are concentrated on the market in July and December, which on the one hand leads to market supply of prawns Too much concentration in a short period of time will lead to a sharp drop in its sell...

Problems solved by technology

[0002] At present, the single-pond structure is usually adopted in the cultivation process of prawns. Generally, one crop is cultivated in a year, and at most two crops are cultivated. As a result, the shrimp ponds are idle for at least 100 days during the time suitable for prawn farming, resulting in the lack of reasonable use of production materials. The resources used are wasted; in addition, because the current prawn farmers mostly adopt the above-mentioned traditional aquaculture structure to produce prawns, most of the finished prawns are concentrated on the market in July and December, which on the one hand leads to market supply of prawns Too much concentration in a short period of time will lead to a sharp drop in its selling price. On the other hand, there will be no sufficient supply of fresh and live shrimp products in the market during the non-traditional shrimp harvest season.
