Abstract

The invention discloses an artificial breeding method of tachysurus fulvidraco. The artificial method mainly includes the following steps that firstly, pond conditions are selected, wherein the area of a pond is 8 to 10 mu, the water depth is 1.8 m to 2 m, and quicklime pond cleaning and disinfecting are carried out in the pond before the tachysurus fulvidraco fries are cast; secondly, casting of the tachysurus fulvidraco fries is performed, wherein 6000 to 7000 tachysurus fulvidraco fries per mu are cast and bred in April, feed is cast for feeding from the last ten days of April to November, the conventional feed selected each time is cast according to 1.5 percent to 3 percent of the weight of the tachysurus fulvidraco fries, and the feed is cast twice every day; thirdly, the water quality of the pond is guaranteed; biological agents are used for regulating the water quality once a month from June to September, the amount of the biological agents used each time is 500 g to 1000 g per mu, water is not replaced in the first month and is replaced one to two times after one month, and water which is 10 centimeter to 20 centimeter in depth is replaced each time; fourthly, breeding and oxygenation are performed, wherein one aerator is added to the pond area of every three mu, and the aerators are turned on for oxygenation two hours before each time of feed casting during June to September. According to the artificial breeding method of the tachysurus fulvidraco, the sufficient oxygen content of the pond can be kept, the feed intake amount of the tachysurus fulvidraco fires is increased, in addition, harmful matter in the water can be evaporated while oxygenation is carried out in the pond, and therefore the water quality is adjusted.

Description

technical field [0001] The invention relates to an artificial cultivation method of yellow catfish, which belongs to the technical field of fish artificial cultivation. Background technique [0002] Peeled catfish belongs to Siluriformes and Catfishidae in classification. Although it is small in size, its meat is delicious and nutritious, and it is very popular with consumers. Based on this, a new technology for artificial breeding of yellow catfish has been developed in recent years. , including the following: [0003] a. Pond conditions: the area is 3-5 acres, the water depth is 1.5-2 meters, the pond requires convenient drainage and irrigation, and the water volume is sufficient; before the fish species are put into the pond, the clear pond is disinfected with quicklime to completely remove wild fish and kill pathogenic organisms; [0004] b. Stocking of fish species: The stocking of fish species can be carried out in proportion according to the main breeding and breedin...
