Method for cultivating eriocheir sinensis in small pool

Abstract

The invention relates to a method for cultivating eriocheir sinensis in a small pool. The method comprises 14 main steps. The small pool made of bricks and concrete or glass fiber reinforced plastic is adopted, and the normal growth environment of the eriocheir sinensis is simulated by taking measures of paving shelters at the bottom of the pool, transplanting aquatic plants and putting spiral shells; the water temperature of the pool in a high-temperature period is reduced by erecting a sunshade net; blue-green algae generation can be effectively avoided by utilizing the water purification function of silver carps, the aquatic plants and the spiral shells; and the high water quality condition of the small pool and the stable aquatic ecological environment are guaranteed by cleaning the bottom of the pool at a fixed period, using a discontinuous micro-running water mode, applying EM bacteria at a fixed period and increasing oxygen timely, and artificial control on the eriocheir sinensis cultivation environment is basically realized.

Description

technical field [0001] The invention relates to a method for cultivating Chinese mitten crabs, in particular to a method for cultivating Chinese mitten crabs in a small pool. Background technique [0002] Chinese velvet crab, commonly known as river crab and hairy crab, is mainly distributed in the three major freshwater water systems of the Yangtze River, Liaohe, and Oujiang rivers in my country. It is an important economic breeding species for freshwater fisheries in my country. As a treasure among aquatic products, river crabs are deeply loved by people because of their delicious taste, tender meat and rich nutrition. River crab culture is one of the main ways for the majority of farmers (fishermen) to increase their income and get rich. At present, the artificial breeding area of ​​river crabs in the country is about 15 million mu, with an annual output of about 600,000 tons and an annual output value of about 50 billion yuan. Enclosed breeding mode, there are few smal...

Problems solved by technology

The most prominent defect of the extensive large pond crab culture model is that it is greatly affected by natural environmental conditions (such as low temperature, high temperature, wind and rain, water pollution, etc.), coupled with large water body capacity and high-density culture, continuous artificial feeding will easily lead to water quality and poor quality. Pond bottom conditions have deteriorated, and man-made control over the overall water quality and pond bottom conditions is low, resulting in the production of river crabs being controlled by natural conditions and water quality conditions to a certain extent
