Problems solved by technology

It can be seen that there is a long idle period in the traditional mandarin fish culture, during which the mandarin fish pond has a large space for utilization; the bait fish that the mandarin fish feeds on has high cost, low yield, and high difficulty in breeding
The above factors directly restrict the per unit yield benefit of mandarin fish culture

Embodiment

[0020] The specific breeding method is as follows:

[0021] a) Preparation before breeding. The preparation before breeding includes: selecting mandarin fish ponds and bait fish ponds, removing impurities, exposing and disinfecting dry ponds, and planting ryegrass at the bottom of mandarin fish ponds. Among them, the ratio of the area of ​​the mandarin fish pond to the bait fish pond is 1:5, and the water depth of the pond can reach 2m. The inlet and outlet of the pond are surrounded by steel wire mesh or iron fence to prevent the escape of shrimp and fish and the entry of harmful organisms. The draining of pond water should be carried out in November. After the pond is dried, weeds and pond bottom silt should be removed and the pond ridge should be reinforced. Then, it should be exposed to the sun for 20 days in winter, and then limed water should be used at a rate of 150kg / 667m 2 Sprinkle the whole pond with the amount, and rake the bottom mud evenly. The area of ​​mandarin...

Abstract

The present invention provides an efficient culture method for mandarin fishes and crayfishes in a pond. The culture method comprises the following steps: a) pre-culture preparation; b) stocking and feeding of crayfishes; c) stocking of forage fishes of spotted silver carps / silver carps; d) stocking and feeding of Cirrhinus mrigala forage fishes; e) stocking and feeding of mandarin fishes; and f) water quality management. The present invention discloses an efficient culture method for mandarin fishes and crayfishes in the pond. The culture method is scientific and reasonable, and by breeding one-season crayfishes and culturing low-cost the Cirrhinus mrigala forage fishes in a special pond, the comprehensive utilization rate of the pond is improved, the yield is increased, and the culture cost is greatly lowered, so that a relatively high economic benefit is achieved.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to an efficient pond culture method for mandarin fish and lobster, and belongs to the technical field of aquaculture. Background technique [0002] Aquatic products are an important source of high-quality protein for human beings. They are rich in high-quality protein, amino acids, vitamins and minerals, etc., and the quantity and ratio meet the needs of the human body, especially containing leucine and lysine that are in large demand for the human body. With the improvement of people's income level, more and more people begin to regard nutritional needs as the first need of food consumption, and the proportion of consumption of aquatic products shows an increasing trend year by year. At this stage, there are more than 50 types of aquatic products for large-scale farming in my country, and industrial farming, deep-water cage farming, and ecological farming are developing rapidly. Aquacultur...
