Crucian breeding method

Abstract

The invention discloses a crucian breeding method, and relates to the field of aquaculture. The method comprises the following steps that a fish pond is cleaned and disinfected before fry are bred; water is injected into the fish pond; one week after water injection, the fry are bred; shrimps and snails are bred in the fish pond; the fry are fed with mixed feed with the protein content of 39-40%;the water quality is controlled according to the water quality condition of the fish pond by using 10-20 kg of quick lime per mu; fresh water is regularly supplemented into the fish pond. According tothe artificial crucian breeding method, additives are added into the mixed feed, so that the feed has the function of inducing food taking and promoting growth; the raw materials of the additives arestable in source so that the small and gustation requirements of crucian for the compound feed can be met, and the feeding speed and the food intake are obviously increased; the effective componentsand proportions of the feed additives are optimized by the inventor in long-term experiments, the anti-stress capability and growth speed of the crucian can be remarkably improved while the food calling performance is improved, and meanwhile the feed coefficient is reduced; the feed additives are safe and efficient and have no toxic and side effects after long-time use.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating crucian carp. Background technique [0002] Crucian carp, referred to as crucian carp, commonly known as crucian carp, moon crucian carp, soil crucian carp, fine head, carp, cold carp) is a common freshwater fish in Eurasia, and it is one of the fishes of the genus Cyprinidae of the order Cyprinidae of the ray-finned fishes kind. Crucian carp is mainly an omnivorous fish that eats plants. It likes to live in groups and choose food; the meat is tender and has high nutritional value. Every 100 grams of meat contains 13 grams of protein, 11 grams of fat, and contains a lot of calcium, Minerals such as phosphorus and iron. Crucian carp has extremely high medicinal value. Its nature is flat and sweet, and it enters the stomach and kidney. Due to the high nutritional value of crucian carp, the aquaculture industry of crucian carp has also been developed rapidly. H...

Problems solved by technology

Due to the high nutritional value of crucian carp, the aquaculture industry of crucian carp has also been developed rapidly. However, the aquaculture of crucian carp has low feed utilization rate, resulting in slow growth of crucian carp and high mortality rate of crucian carp in the breeding process, which further affects the breeding. profits, this situation seriously hinders the further development of freshwater fish farming and feed manufacturing
