The compound feed provided by the invention has the advantages of enhancing the growth speed and survivalrate of the young scylla paramemosain.

Disclosed is a phagostimulant of pseudosciaena crocea larvae, which comprises inosinic acid, clam worm extract, oxyneurine, alanine, glycine, cuttlefish internal organ powder and tomatine by the weight ratio of 20-30, 25-35, 15-20, 10-15, 8-10, 6-8 and 1-3.

A phagostimulant of prawn for decreasing the cost of its feed by using it as the additive of feed is proportionally prepared from dimethyl-beta-thetin propionate, hypoxanthine nucleotide, taurine, glycine and glutamic acid.

The invention relates to a protein-saving compound feed for young megalobrama amblycephalas and a preparation method of the protein-saving compound feed. The feed is mainly prepared from the following raw materials: 3-5% of fish meal, 17-22% of soybean meal, 10-15% of rapeseed meal, 10-15% of cottonseed meal, 8-10% of peanut meal, 3-5% of whole-milk extruded soybean, 5-8% of whole-milk vegetable seed, 5-8% fermented cottonseed meal, 3-5% of corn lee protein, 8-10% of wheat bran, 8-10% of wheat shorts, 1-2% of alpha-starch, 0.05-0.1% of bile acid and salt emulsifying agent, 0.015-0.03% of glycyrrhetinic acid, 1% of monocalcium phosphate and 1% of compound-premix for intensively-cultured fishes. The preparation method comprises the following steps of: stirring the raw materials in a stirring machine and introducing steam to prepare grains with the grain size of 1-2mm, and then, dewatering and cooling to the room temperature. By using the protein-saving compound feed for the young megalobrama amblycephalas, provided by the invention, the problem of unbalanced nutrition of the compound feed in the current culture of the young megalobrama amblycephalas is solved, the physical condition of the of the young megalobrama amblycephalas is improved, the growth speed of the young megalobrama amblycephalas and the feed utilization ratio are increased, and the feed production cost and the pollution to a water body in the culture process can be reduced.

The invention discloses a compound feed of an adult green crab and a preparation method thereof. The compound feed is characterized by comprising the following components in parts by weight: 25-30 parts of fish meal, 18-25 parts of soybean meal, 5-10 parts of corn protein powder, 5-10 parts of fermented soybean meal, 5-10 parts of peanut meal, 3-5 parts of beer yeast, 3-5 parts of crab shell powder, 2-4 parts of squid liver powder, 1.5-2 parts of fish oil, 1-2 parts of soybean oil, 3-5 parts of soybean lecithin, 0.5-1 part of cholesterol, 15-25 parts of flour, 0.2-0.5 part of vitamin mixture and 0.5-1 part of mineral substance mixture. The preparation method comprises the following steps: mixing the components; hardening and tempering the mixture at certain steam pressure, humidity and temperature; curing the mixture after hardening and tempering at certain temperature, pressure and time; and finally, extruding the mixture into the feed the particle diameter of which is 0.5-3mm, thereby obtaining the compound feed of the adult green crab. The invention has the advantages of improving the digestibility and survival rate of the adult green crab.

Disclosed is a phagostimulant for sole larvae which comprises inosinic acid, clam worm extract, oxyneurine, alanine, arginine and Sunset yellow by the weight ratio of 25-35, 25-35, 15-20, 10-15, 8-10 and 1-3.
