Abstract

The invention provides a method for rotation culture of crawfish and giant fresh water prawn. The method comprises the steps of 1, pond construction and disinfection treatment, 2, aquatic plant cultivating and water body treatment, 3, crawfish stocking and fishing, 4, giant fresh water prawn stocking and fishing, and 5, feeding management; in the crawfish feeding stage, the pH value of the pond is kept between 7.8 and 8.5, the dissolved amount of oxygen in the pond is kept at 5.5 mg / L; in the rearing stage of the giant fresh water prawn: the pH value in the pond is kept between 7.8 and 8.5, and the dissolved amount of oxygen in the pond is kept at 4.5 mg / L. The method for rotation culture of crawfish and giant fresh water prawn raises crawfish and giant fresh water prawn in a reasonable season by rotations, the water body system is reutilized, the utilization rate of the pond is increased, the risk of the farming process is subdued, and the method has a significant economic effect.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating crayfish and Macrobrachium rosenbergii in rotation. Background technique [0002] Freshwater crayfish is an economical freshwater shrimp species with six major characteristics: first, it is large and plump; second, it grows fast and has a high yield; Fifth, it has miscellaneous food habits, it can eat animal feed, artificial compound feed and humus; sixth, it has high economic benefits. The origin of Macrobrachium rosenbergii is concentrated along the coast of Ecuador, and it is currently one of the three largest shrimp species in the world. Macrobrachium rosenbergii is a kind of economical shrimp with fast growth speed, wide diet and rich nutrition. It is large in size, up to 40 centimeters in size and 600 grams in weight. [0003] At present, the rearing of crayfish and Macrobrachium rosenbergii is usually separated and reared in different modes. ...
