Special feed for high-density culture of carps and culture method thereof

Abstract

The invention discloses a special feed for high-density culture of carps and a culture method of the carps, and belongs to the technical field of freshwater fishes. The special feed comprises fish meal, pork powder, chicken meal, soybean meal, rapeseed meal, cottonseed meal, vinasse protein feed, rice bran, corn protein powder, flour, soybean oil, vitamin premix, trace element premix, monocalciumphosphate, choline chloride, vitamin C phosphate, a mildew preventive, an antioxidant, vitamin E, L-carnitine hydrochloride, threonine, lysine and methionine. The breeding method comprises the three steps of breeding pond environment control, fry releasing and feeding control. According to the invention, the components in the formula are reasonably proportioned according to the nutritional requirements of carp organisms; the utilization rate of the carp feed is increased, the pollution of metabolites such as nitrogen and phosphorus to aquaculture water is reduced, and the sustainable development of carp aquaculture is promoted. Meanwhile, the matched breeding mode is high in stocking density, the utilization rate of pond water resources is high, and the output benefit per unit area is greatly improved.

Description

technical field [0001] The invention relates to the technical field of freshwater fish breeding, in particular to a special feed for high-density carp breeding and a breeding method thereof. Background technique [0002] Carp is one of the fish with the longest farming history and the highest yield. Carp is a typical bottom omnivorous fish. It generally likes to move in the underwater layer. It mainly eats zooplankton in the fry stage, and snails, chironomus larvae, small fish and shrimp, etc. in the adult stage, and also eats various aquatic plants, grass roots, and plant fruits. and plant debris. Carp are highly adaptable and can survive in harsh environments. For example, it can grow well in the range of water temperature 15°C-30°C. It is not only resistant to cold and hypoxia, but also resistant to salt and alkali. It grows well in salt water less than 7g / L, and the most suitable salt content is 1-4g. / L. [0003] Carp is tender in quality, delicious in taste and aff...

Problems solved by technology

At present, the stocking density of carp breeding is generally 1000-2500 fish / mu, and the existing carp special feed mainly matches this kind of stocking mode; however, in recent years, the carp market has generally declined, and the breeding efficiency per mu is low

Especially in the northern regions, it is imperative to increase the breeding efficiency per acre by increasing the stocking density. However, after increasing the stocking density, there will be a lack of suitable carp special feed, which cannot meet the growth needs of carp, which may bring greater economic benefits.
