Problems solved by technology

Feeding small miscellaneous fish not only has a high feed factor, but also easily introduces pathogens and pollutes the breeding environment. In addition, the supply of chilled small miscellaneous fish is restricted by fishing seasons and seasons, and it is difficult to guarantee the freshness and quality of fish. The nutritional parameters of the compound feed fed to other fish species are not specially set for juvenile yellow croaker, so the growth and weight gain rate of croaker can not reach its optimal growth state

Abstract

The invention discloses young nibea albiflora compound feed and a preparation method thereof. The compound feed consists of fish meal, bean pulp, wheat protein powder, fish oil, dextrin, soya bean lecithin, multidimensional premix, multi-mineral premix, choline chloride, monocalcium phosphate, a composite immunopotentiator and cellulose. The feed formula is designed by specially aiming at the nutritional requirements, ingestion characteristics and digestion characteristics of young nibea albiflora, and the total nutrient requirements needed by growth and development of the young nibea albiflora can be met. The feed formula disclosed by the invention is comprehensive and balanced in nutritional ingredients and is green, environmentally friendly and good in stability performance in water. The culturing experiment proves that the feed disclosed by the invention can achieve the effects of obviously improving the weight gain rate and survival rate of the nibea albiflora and improving the disease resistance of the nibea albiflora.

Description

[0001] Technical field: [0002] The invention relates to the technical field of agricultural seawater aquaculture, in particular to a compound feed for young yellow croaker fish and a preparation method thereof. [0003] Background technique: [0004] Croaker Nibea albiflora Richardson ), belonging to the order Perciformes, Tochiocephalidae, and the genus Pseudomonas, warm-temperate offshore pelagic fishes, mainly distributed in the Northwest Pacific, and distributed in the South my country Sea, the East China Sea and the Yellow Sea. Its meat is delicious, nutritious and fast-growing, with few diseases. It can reach the commercial fish market specifications in the same year of breeding. It has become a new species with great development potential for marine fish cage culture. However, there is currently a lack of compound feeds developed solely for the characteristics of yellow aquarium juveniles. [0005] In the current yellow croaker farming, only chilled trash fish and other fish...
