Mixed aquaculture method

Abstract

Provided is a mixed aquaculture method. The mixed aquaculture method comprises the following steps of 1 pond preparing including pond structure construction and pond sterilization treatment, wherein in the process of pond structure construction, after a pond is constructed, water in a deep trench is pumped away, the deep trench is exposed to the sun for 3 days to 7 days under sun illumination, seawater is introduced and is 30-50 cm higher than shallow, the PH value of the seawater is detected, and nutritional feed is put; 2 breed stocking, wherein young Chinese forest frogs are laid in the shallow, the young Chinese forest frogs with the size that the weight of one thousand grains is one jin are adopted, young shrimps are stocked in the water, and when the young Chinese forest frogs grow until the weight of 200 grains to 250 grains is one jin, young green crabs are stocked in the deep trench with the density of 10 young green crabs per square meter of the area of the water surface of the deep trench; 3 feeding and managing in the pond, wherein a fungus nutrition solution is put into the water at a fixed period, troughs are arranged in water beside the deep trench at intervals, and feed is put into the troughs.

Description

technical field [0001] The invention relates to a method for aquaculture mixed culture. Background technique [0002] At present, an important development direction of the aquaculture industry is "polyculture", and the main types include polyculture of fish and shrimp, polyculture of fish and turtle, polyculture of fish and crab, etc. However, under the polyculture mode, each species has different requirements for feed, nutrition and environment, so it is very difficult to breed. [0003] Moreover, in the breeding process, for example, snow clams have lower environmental requirements and are relatively easy to breed, but the cycle is too long, and they are prone to malnutrition, resulting in less meat quality and slower volume growth, which takes more than two years; while the breeding cycle of shrimp and crab is short, A certain depth of water is required, but the mortality rate is high, and it is easy to be affected by the weather, causing hypoxia or illness.
