The invention discloses a penaeus vannamei phagostimulant. The penaeus vannamei phagostimulant comprises following components in parts by weight: 10-15 parts of glycine betaine, 6-8 parts of taurine, 2-3 parts of nucleotide, 10-15 parts of alanine, 10-15 parts of glycine, 3-5 parts of smoked plums,1-4 parts of spina date seeds, 2-6 parts of mints and 3-6 parts of rhizoma kaempferiae. According to the penaeus vannamei phagostimulant, the phagostimulant which is 0.05%-2% of the weight of penaeus vannamei compound feeds is added into the penaeus vannamei compound feeds so as to cover bad smell in the compound feeds and stimulate sensory organs of penaeus vannamei to promote the penaeus vannamei to ingest and accelerate the growth; furthermore, the phagostimulant is used for inducing the penaeus vannamei to ingest so as to reduce residual feeds in a water body, increase the utilization rate of the feeds and alleviate secondary pollution to the water by the residual feeds, and furthermore, disease risks of the penaeus vannamei are reduced and the survival rate of the penaeus vannamei is increased.

The preparation method provided by the invention comprises the following steps: mixing the components; carrying out the quenching and tempering on the mixture under certain vapor pressure, humidity and temperature; curing the mixture after the quenching and the tempering under the conditions that the temperature is 135 DEG C, the pressure is 3MPa, and the timeis 90-120 seconds; and finally, extruding into the feed with the particle diameter 0.1-0.5mm. 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.

The present invention discloses a preparation and use method of sebastodes fuscescens, the ingredients and the weight percentage of which are: 35 to 45 percent of betaine, 25 to 35 percent of inosinicacid IMP, 15 to 20 percent of dimethyl-Beta-propiothetin, 8 to 15 percent of glycine and 5 to 10 percent of sodium citrate; the feeding promoting agent is prepared by that various raw materials used for preparing the feeding promoting agent are dried, grinded, weighed accurately according the dosage and mixed fully and evenly with the coefficient of variation being less than or equal to 5 percent; the feeding promoting agent of feedstuff is applied to the compound feedstuff of the sebastodes fuscescens by the proportion of 0.5 (weight percentage), and can promote the ingestion and the growth of the sebastodes fuscescens with 82.06 percent of the rate of body weight gain, 1.29 percent of specific growth rate and 2.81 percent of ingestion rate; meanwhile, the used raw materials have stable source, low price, simple manufacturing technique and little waste feedingstuff, reduce remnant feed, is beneficial to environmental protection and can carry out the production and the aquaculture of the sebastodes fuscescens on large scale.
