Embodiment 1

[0022] Embodiment 1 Changjiang river crab standardized cultivation

[0023] It mainly includes pond reconstruction, preparatory work, seedling throwing, pond management and other steps:

[0024] (1) Pond reconstruction: A circular ditch needs to be excavated around the pond, and a 0.5-meter-deep circular ditch (ie crab ditch) should be excavated about 2 meters away from the pond. The pond is divided into three areas, ABC: the annular ditch is B area, The side near the shore outside the annular ditch is the A region, and the other side is the C region; wherein the A region accounts for 10% of the pond mouth area, the B region accounts for 30% of the pond mouth area, and the C region accounts for 30% of the pond mouth area. 60%; anti-escape facilities are set up on the shore and in the embankment of the pond, and double-layer plastic film is erected on the shore, which is more than 50cm above the ground, and the inlet and outlet are separated, and microporous oxygenation facilit...

Abstract

The invention discloses an Eriocheir sinensis standard aquaculture method. The aquaculture method includes the following steps: pool reconstruction, early stage preparation, larva throwing, pool management and catching and selling. The Eriocheir sinensis standard aquaculture method is simple to operate, is low in aquaculture cost, is reasonable in density, is conductive to cultivation of large-size Eriocheir sinensis, can greatly improve the proportion of large-size high-quality Eriocheir sinensis, and can practically improve the aquaculture benefits.

Description

technical field [0001] The invention relates to the technical field of cultivation, and relates to a standardized cultivation method for Yangtze river crab. Background technique [0002] The scientific name of Yangtze river crab is Chinese mitten crab, which is a special freshwater product of the Yangtze River system. Because of its bright color, tender meat, unique taste and rich nutrition, it is known as "the top grade in the water and a delicacy for banquets", and is deeply loved by consumers. In recent years, the river crab market has fluctuated greatly, especially the price of small-sized and poor-quality river crabs has been falling all the way, while large-sized river crabs with good quality have an advantage in the market game, not only selling well, but also keeping prices firm. In the prior art, there is no unified standard for the breeding process of the Yangtze river crab, which results in different sizes and quality differences of the Yangtze river crab. Therefo...
