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

[0028] The nutritional composition of the prepared feed is: water, 9.43%; crude protein, 40.1%; crude fat, 16.7%; crude ash, 10.6%

Embodiment 3

[0031] The nutritional composition of the prepared feed is: water, 10.4%; crude protein, 54.7%; crude fat, 9.64%; crude ash, 13.4%

[0032] Two preparation method

[0033] Grind the solid feed raw materials with a pulverizer, and pass all the crushed feed through a 60-mesh sieve; weigh all kinds of feed raw materials according to the proportion of the feed formula, and mix them according to the principle of step-by-step expansion, and the mixing time is more than half an hour ;Put the fully mixed raw materials into a mixer and add water to stir. When the humidity reaches 8%-12%, pass through an extruder and a granulator to make granular feed with a diameter of 2mm and 3mm; air-dry the prepared feed at room temperature (moisture content below 12%), put it into a sealed bag, and store it in a -20°C refrigerator for later use.

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

Technical field: [0001] The invention relates to the technical field of agricultural mariculture, in particular to a compound feed for juvenile yellow croaker and a preparation method thereof. Background technique: [0002] yellow croaker ( Nibea albiflora Richardson ), belonging to Perciformes, Totoabaidae, crocus, warm-temperate coastal middle and lower layer fish, mainly distributed in the Northwest Pacific region, and distributed in the South China Sea, East China Sea and Yellow Sea in my country. It has delicious meat, rich nutrition, rapid growth, and few diseases. It can reach the market standard of commercial fish in the same year of breeding, and 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 juvenile yellow croaker. [0003] In the current culture of yellow croaker, only chilled small miscellaneous fish and other fish compound ...
