Embodiment Construction

[0036] Take two 100 meters each 2 The second-layer bottom of the Penaeus japonicus submerged sand culture pond is an example. The pool is square, the depth of the pool is 2.3 meters above the sand, and it is half underground. A gas riser pipe 11 is established in the No. 2 pool, and a cement slab not covered with sand is established around the gas riser pipe 11 . 3 layers of shrimp leak-proof nets 15 and sewage well 7 are set in No. 1 pond, and the internal diameter of sewage well 7 is 1 meter. On July 29, after spreading sand in each pond, add 1 meter deep water, 50 centimeters of water depth on the sand, apply 12 kilograms of bleached powder crystals (concentration 120PPM) to disinfect the pond water and the sand layer in each pond. After spraying, use the water-changing drain hose 12 to discharge the non-sterilized water under the sand layer, so that the upper disinfected water is reduced to close to the sand plane, so that the lower space is full of disinfected water, so...

Abstract

The high-yield breeding method of Japanese prawn includes controlling white spot of Japanese prawn with two-layer latent-sand aquiculture pond, convective circulating sand washing via pneumatic lift of water, automatic dirt collection and drainage via horizontal circulating flow, through and feeding live feedstuff through special treatment, applying prawn disease treating chemical powder and water sterilizing medicine, using transparent plastic house and hibernation via using solar energy completely. The aquiculture pond is downwards inclined towards the center and has water inlet and drainage holes, dirt drainage hole, dirt drainage well, support under the pond bottom, porous plate, screen, sand layer and spawn escape preventing net.

Description

technical field [0001] The invention relates to aquaculture, in particular to a method for cultivating prawns and a pond for cultivating them. Background technique [0002] Japanese shrimp, also known as car shrimp, flower shrimp, bamboo shrimp, and zebra shrimp, are widely distributed in the Indian and Pacific regions, and are also distributed along the south coast of Jiangsu Province, China. Penaeus japonicus has the characteristics of rapid growth, strong disease resistance, and long-term immortality out of water. It is suitable for long-distance dry transportation and live sales, and is an important foreign exchange-earning fishery product. Japanese prawns are firm in meat quality, rich in protein, delicious in taste, and have a unique flavor when eaten fresh. They are welcomed by markets all over the world. The Japanese like to eat raw Penaeus japonicus for hundreds of years. The Japanese market has a great demand for fresh and live Penaeus japonicus, and the price has...
