Problems solved by technology

At present, the domestic and foreign research reports on snails mainly involve the ecology, breeding habits and artificial breeding of snails, and there is no report on the compound feed of snails.
Therefore, most of the large-scale artificial breeding currently uses natural fresh and frozen bait, such as variegated clams and miscellaneous fish, so it is not only easy to pollute the water quality, but also the cost of breeding is high, resulting in the economic benefits of snail culture and the income of the farmers. reduce

Abstract

The invention discloses a compound feed used for culturing hemifusus tuba gmelin, which is prepared from alpha-starch, dehulled soybean meal, peanut cake, domestic brown fish meal, white fish meal, dextrin, fish oil, soya-bean oil, gelatin, compound vitamin, compound mineral substance and feeding promoting agent as raw materials through the steps of mixing, stirring and pelleting. The feed has the advantages of reasonable nutrient collocation, better growth of the hemifusus tuba gmelin, better food calling effect to the hemifusus tuba gmelin, longer form-maintaining time and better palatability, is beneficial to the growth of the hemifusus tuba gmelin, and is suitable for the feeding of the hemifusus tuba gmelin. The survival rate of the hemifusus tuba gmelin fed by singly using the compound feed is above 90 percent. Therefore, the feed can replace natural baits, such as sinonovacula constricta, potamocorbula laevis, ruditapes variegata, trash fish and the like, thus the cost of the feed for culturing the hemifusus tuba gmelin is lowered and the economic efficiency of culturing the hemifusus tuba gmelin is increased.

Description

technical field [0001] The invention relates to a compound feed, in particular to a compound feed for cultivating snails. Background technique [0002] Pipe angle screw ( Hemifusus tuba) , gastropod (Gastropoda) , Galeodidae (Galeodidae), live in the soft mud and sandy bottom of the subtidal zone offshore 11-40m. Mainly distributed in the southeast coast of my country and the Sea of ​​Japan. Its meat is plump, fresh and tender, has a unique taste, and is rich in nutrients such as protein and unsaturated fatty acids. It is a marine treasure with a certain health care effect, and is very popular in domestic and foreign markets. However, in recent years, due to unreasonable resource utilization, the number of wild snails has been decreasing day by day, and the market price is high, and the supply is in short supply. Snails are carnivorous molluscs, and they like to eat bivalves under natural conditions, especially those with thin shells and no filaments, such as clams, blu...
