Semi-closed ecological desalination culture method of penaeus orientalis

Abstract

The invention discloses a semi-closed ecological desalination culture method of penaeus orientalis. The semi-closed ecological desalination culture method of penaeus orientalis comprises the followingsteps that a, firstly, a shrimp culture pond is constructed; b, young penaeus orientalis are cultured in an inner pond, then the cultured penaeus orientalis is put into an outer pond, the putting time is selected in May, the temperature is controlled at 22-24 DEG C, the stocking density of the outer pond is 30000-40000 ind/mu, and the density should not exceed 2500 ind/m<3> in the water body; c,water quality management is carried out on entered water, before stocking, clean growing water or growing water subjected to disinfection or wild shrimp eliminating treatment is injected into a growing pond, the growing water is subjected to reservoir precipitation, purification treatment and water amount and water exchange, in the growing early stage, 3-5 centimeters of water is added every day until the water level reaches 1 meter or above, and the water level is maintained; d, feeding management is carried out; e, young penaeus orientalis is collected. The semi-closed ecological desalination culture method of penaeus orientalis has the advantages that living habits and growing characteristics of penaeus orientalis are fully considered, the meat of the cultured penaeus orientalis is delicious, the nutrition is rich, the survival rate is high, the incidence rate is low, the culture cycle is shortened, the culture cost is saved, and the promotional value is higher.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a semi-enclosed ecological desalination cultivation method for prawns. Background technique [0002] Prawns, scientific name Oriental prawns, also known as Chinese prawns, Chinese prawns), and prawns. Arthropoda, Mollusca, Decapod, Shrimpidae, Penaeus. Prawns are large in size and are commonly known as prawns. The female growth of prawns generally has a body length of 16-22 cm and weighs about 50-80 grams. The largest can reach 30 cm and weighs 250 grams; the male is smaller, with a body length of 13-18 cm and a weight of 30-50 grams. Prawns are wide-temperature and wide-halt marine animals. The body of Penaeus mangniu Island is long cylindrical, flat on the left and right sides, and the body is divided into head, thorax and abdomen, and consists of 20 body segments. The abdomen is long, muscular and well segmented. [0003] Prawns are rich in nutrients a...

Problems solved by technology

[0003] Prawns are rich in nutrients and delicious in taste, and are deeply loved by people. In many areas, the supply is often in short supply. The main traditional cultivation methods have low yields and unscientific cultivation techniques. The cultivated prawns are small in size and low in protein content. The above problems need to improve the traditional breeding method, so here we propose a semi-enclosed ecological desalination cultivation method of prawns to improve the production of prawns.
