Culture method of mandarin fish

Abstract

The invention relates to a culture method of mandarin fish. The culture method includes the following steps of 1, building a pond; 2, disinfecting the pond; 3, injecting water into the pond; 4, putting bait fish in the pond; 5, putting mandarin fish fry in the pond; 6, culturing the mandarin fish, wherein the water temperature in the pond, the PH value, the nitrogen content and the nitrite content of water and the oxygen solubility in the water are regularly detected every 10 days; 7, obtaining the mandarin fish. According to the method, the bait fish and the mandarin fish are cultured in a polyculture mode, the problem that bait supply is insufficient at times in mandarin fish culture and consequently the mandarin fish yield is low is solved, the culture density is uniform and suitable for growth of the mandarin fish, and thus the yield is high; it is avoided that a worker spends time putting bait every day, so that the culture cost of the mandarin fish is lowered; furthermore, the well water is adopted for culturing the mandarin fish, so that reproduction and growth of pathogenic bacteria in the water are restrained, diseases are reduced, the yield of the fish is increased, and the quality of the fish is improved.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a method for cultivating sweet-scented osmanthus fish. Background technique [0002] Sweet-scented osmanthus fish, belonging to the genus Siniperca genus, has a tall body and flattened sides, a raised back, a large mouth, and the lower jaw is obviously longer than the upper jaw. Serrated, with 4 large spines on the lower edge; 2 large spines on the posterior edge of the operculum; the head has scales, the scales are small; the lateral line curves upward along the dorsal arc; the dorsal fin is divided into two parts, connected to each other, and the front part is Hard spines, soft fin rays at the back; body yellow-green, belly off-white, with irregular dark brown spots and plaques on the side of the body; there is a long and narrow black band from the tip of the snout through the eye socket to the front and bottom of the dorsal fin. Sweet-scented osmanthus fish is a typical ...

Problems solved by technology

[0003] The traditional culture of sweet-scented osmanthus fish adopts the method of raising fry and bait fish separately. Putting 800-100 fry and 1.2-1.5 million bait fish per mu, not only the high density will easily lead to the lack of oxygen in the fish, but also waste Manpower and time are used to put in bait fish, which is time-consuming and labor-intensive; in view of this, the present invention proposes a method of mixing fry and bait fish, that is, a method for cultivating sweet-scented osmanthus fish
