Method for semi-closed ecological desalination cultivation of penaeus monodon

Abstract

The invention belongs to the field of prawn farming and breeding, and discloses a method for the semi-closed ecological desalination cultivation of penaeus monodon. The method comprises the steps: building an ecological cultivation cement pit in a semi-closed ecological cultivation workshop, and then carrying out the ecological desalination cultivation of penaeus monodon. The method comprises the specific steps: building the ecological cultivation workshop, building an ecological desalination cultivation cement pit, clearing the bottom of the cement pit, carrying out water planting, placing seedlings, carrying out desalination management and water quality regulation and control, carrying out feeding management, and collecting young shrimps. Through the building of the semi-closed cultivation cement pit, the method achieves the desalination cultivation of the penaeus monodon, and creates a natural growth environment for the young penaeus monodon. After the desalination cultivation, the young penaeus monodon is healthy and strong and is high in adaptive capacity. The size of the young penaeus monodon can be greater than 1.5cm, and the rate of survival is improved by 25%, thereby facilitating the reduction of the cost in big water ecological cultivation of the penaeus monodon, and improving the cultivation benefits.

Description

technical field [0001] The invention belongs to the technical field of prawn culture and seedling cultivation, and in particular relates to a semi-enclosed ecological desalination cultivation method of Penaeus monodon. Background technique [0002] Shrimp farming is the pillar industry of aquaculture industry in my country and even in the world. Penaeus monodon is one of the three main species of prawns cultured in my country. It is commonly known as grass shrimp and ghost shrimp. It is large in size, delicious in meat and rich in nutrition. , is the largest shrimp in the world. It has broad-salinity and strong disease resistance. At present, in the Pearl River Estuary, the aquaculture area of ​​Penaeus monodon reaches 200,000 mu, and the farming method is mainly a large-water surface ecological farming model. The area of ​​each pond is generally 50-100 mu, and it is usually mixed with blue crabs and yellowfin breams. However, due to The salinity of the water body is low d...

Problems solved by technology

At present, in the Pearl River Estuary, the aquaculture area of ​​Penaeus monodon reaches 200,000 mu, and the farming method is mainly a large-water surface ecological farming model. The area of ​​each pond is generally 50-100 mu, and it is usually mixed with blue crabs and yellowfin breams. However, due to The salinity of the water body is low during the seedling release period in summer, generally only 2~3, and the seedlings are mainly purchased from high-salinity areas, and the specifications are small, and they are often thrown directly into large water surfaces without harvesting; The standard thickness can improve the survival rate of breeding to a certain extent, but the survival rate of shrimp cultivation and the ability to adapt to the environment cannot meet the needs of the market, which will affect the development of the monodon shrimp industry.
