Special compound feed for Chlamys Farreri and production method thereof

Abstract

The invention relates to a special compound feed for Chlamys Farreri and a production method thereof and belongs to the technical field of aquaculture feed. The special compound feed comprises the following ingredients in parts by weight: 10-20 parts of bean meal, 10-15 parts of peanut meal, 5-10 parts of corn flour, 20-30 parts of alfalfa meal, 5-10 parts of dried marine algae powder, 1-5 parts of fish meal, 2-10 parts of shrimp meal, 1-2 parts of compound vitamins and 1-2 parts of special minerals. The processing method of the special compound feed for Chlamys Farreri comprises the following steps: step (1), weighing the raw materials; step (2), mixing the weighed raw materials and performing rough crushing; and step (3), performing ultrafine crushing to the roughly crushed materials. The special compound feed for Chlamys Farreri has scientific formula and the production method is simple in processes. The special compound feed for Chlamys Farreri produced according to the production method has an appropriate calcium-to-phosphorus ratio. Compared with other feeds, the special compound feed for Chlamys Farreri has the effects of obviously promoting growth of the Chlamys Farreri, shortening the culture cycle and improving the anti-adversity ability; moreover, the special compound feed for Chlamys Farreri is also capable of saving marine algae resources and reducing pollution to the water; thus, the special compound feed for Chlamys Farreri has positive promoting effects to the Chlamys Farreri culture industry and is obvious in economic and social benefits.

Description

technical field [0001] The invention relates to a special feed for Chlamys farreri and a manufacturing method thereof, belonging to the technical field of aquaculture feed. Background technique [0002] Chlamys farreri is favored by consumers because of its unique nutritional value and unique umami taste, and the market demand has risen sharply. In the northern coast of my country, Jiaodong Peninsula, Dalian, and Changshan Island in Liaoning are the main production areas. Wild clam scallops typically filter on single-celled algae and organic detritus and other small microorganisms in seawater. The bait required for artificial culture of Chlamys farreri mainly feeds on algae such as benthic diatoms, sargassum, and sargassum, which are single and easily cause nutritional deficiencies. Meet the needs of sea cucumber seedlings and growth. Because feeding these baits makes the water quality more likely to deteriorate, Chlamys farreri is prone to diseases and has a low survival ...

AI Technical Summary

Problems solved by technology

The bait required for artificial culture of Chlamys farreri mainly feeds on algae such as benthic diatoms, sargassum, and sargassum, which are single and easily cause nutritional deficiencies. Meet the needs of sea cucumber seedlings and growth

Because feeding these baits makes the water quality more likely to deteriorate, Chlamys farreri is prone to diseases and has a low survival rate

In addition, a small number of farming users also use raw materials such as fish meal, mussel meat, scallop edges, soybean meal, and undegummed kelp powder to make their own feed for clam scallops. The feed made from these raw materials generally has high protein and fat content, high viscosity, and insufficient nutrition. Balanced, perishable, polluted water quality and other issues, resulting in low digestion and absorption rate of Chlamys farreri, decreased physical fitness, and susceptibility to disease

It is difficult to fully meet the nutritional needs of Chlamys farreri at each growth stage when using this kind of feed in production, and the breeding effect is poor, so it has no general promotion value
