Problems solved by technology

However, during the cultivation of large yellow croaker juveniles, fresh biological baits such as rotifers and artemia are still relied on. It leads to the decline of seed quality, which seriously affects the breeding of adult fish.

Embodiment 1

[0007] Embodiment 1: Weigh 35kg of white fish powder, 10kg of shrimp powder, 10kg of mussel powder, 10kg of squid powder, 5kg of yeast powder, 5kg of hydrolyzed fish meat protein, 9.72kg of a-starch, 2.0kg of inorganic salt mixture, 2.0kg of vitamin mixture, lure Food preparation 0.1kg, lycopene (pigment) 0.03kg, ethoxyquinoline (antioxidant) 0.05kg, β-glucan 0.1kg, these raw materials are carried out ultrafine pulverization (over 500 mesh), and then with 6kg Mix soybean lecithin and 3kg fish oil evenly, put them into a granulator, slowly add 2kg of matured sodium alginate while stirring, then granulate, and obtain artificial micro-adhesive feeds of different specifications after sieving.

[0008] The experimental results in Xiangshan, Zhejiang show that the survival rate of large yellow croaker juveniles raised by using the artificial micro-granule feed is 18-25% higher than that of other brands of artificial micro-granule feed at home and abroad. Large yellow croaker juvenil...

Embodiment 2

[0009] Example 2: Weigh 40kg of white fish meal, 15kg of shrimp meal, 10kg of mussel meal, 8kg of squid meal, 3kg of yeast powder, 5kg of hydrolyzed fish meat protein, 6.77kg of a-starch, 1kg of inorganic salt mixture, 1kg of vitamin mixture, food attractant 0.1kg, lycopene (pigment) 0.01kg, ethoxyquinoline (antioxidant) 0.02kg, β-glucan 0.1kg, these raw materials are carried out ultrafine pulverization (over 500 mesh), then with 5kg lecithin , 3kg of fish oil are mixed evenly, put into the granulator, slowly add 2kg of mature sodium alginate while stirring, then granulate, and obtain artificial micro-adhesive feed of different specifications after sieving. Among them, white fish powder, shrimp powder, mussel powder, squid powder and yeast powder are prepared under low temperature conditions below 40°C.

[0010] The experimental results carried out in Xiangshan, Zhejiang show that using the above-mentioned artificial micro-granule feed to cultivate large yellow croaker juvenil...

Description

technical field [0001] The invention relates to a feed, in particular to an artificial microparticle feed for juvenile large yellow croaker. Background technique [0002] With the arrival of the fourth wave of marine aquaculture, my country's marine fish aquaculture industry has developed rapidly, and the aquaculture output has increased year by year. Seed cultivation is a key link in seawater aquaculture. Traditional seawater juvenile fish cultivation mainly relies on biological bait, which not only requires a lot of manpower and material resources to cultivate biological bait such as rotifers and artemia, which increases the cost of seedling breeding, but also because biological bait Usually carry pathogenic microorganisms, so it is easy to cause the spread of disease. At the same time, collecting a large number of rotifer and Artemia eggs will lead to resource destruction, which is not conducive to the sustainable use of resources. In addition, biological bait has short...
