Abstract

The invention relates to a special feed for parent fishes of onychostoma macrolepis and a preparation method thereof. The feed is characterized by comprising, by weight, 28.5% of fish meal, 14% of soybean meal, 1.4% of rapeseed meal, 23%-24.7% of cottonseed meal, 11.7%-14.9% of flour, 7.8%-8.5% of rice bran, 1%-8.5% of cellulose, 4.7%-6.9% of soybean oil, 1% of bentonite, 2% of calcium dihydrogenphosphate and 1% of a fish premix, wherein 1 kg of the feed comprises 90-110 g of lipid. By adopting the feed, the problem is solved that there has been no special feed for the parent fishes of onychostoma macrolepis for a long time. Meanwhile, the feed has important significance in promoting the reproduction efficiency and scale of the parent fishes of onychostoma macrolepis and large-scale breeding of onychostoma macrolepis, boosting the development of the industry, increasing the economic income of fishermen to make the fishermen get rid of poverty and become rich, and facilitating the conservation of fishery germplasm resources and the recovery of species diversity in Qinba mountain areas.
