Embodiment approach

[0016] The technology of the present invention uses high-quality white fish powder, shrimp powder, mussel powder, hydrolyzed cod protein powder and hydrolyzed squid protein powder, etc., and adopts a special processing technology to make particulate feed, which can replace 40%- 70% biological bait can increase the survival rate of flounder flounder larvae by 18.8%, increase the special growth rate by 2%, reduce the albinism rate by 30%, and have strong stability in water, and they will not collapse in water for 30 hours. It has the characteristics of selective diffusion, easy to disperse and not agglomerated. The sedimentation velocity reaches 25cm / h.

[0017] Trial production of 1 ton of micro-granule feed, the application effect is good.

[0018] Describe the preparation method of the present invention in detail below by embodiment.

[0019] The present invention is completed according to the following operation techniques: the technical scheme is mainly a preparation meth...

Abstract

A microgranular feed for the young Bothus plaice is prepared from Anabarilius powder, shrimp powder, mussel powder, hydrolytic squid protein powder, hydrolytic pacific cod powder, fish fat, lecithin, bataine hydrochloride, vitamins, minerals, starch, beta-carrotene, tryps ash, and sodium alginate. Its preparing process is also disclosed. Its advantage is high survival rate.

Description

Technical field: [0001] The invention belongs to the compounding technology of seawater fish compound feed, and relates to a compounding method of flounder fish microparticle feed. Background technique: [0002] Fish seed is the material basis of marine fish farming industry, and it is also an important prerequisite to ensure high and stable production. In seawater fish fry cultivation at present, the main problem that occurs is that the cultivation of fish fry depends on live bait. Although so far, the use of live bait is better than artificial compound feed in the cultivation of fish fry, but live bait also has disadvantages when it is widely used. In order to ensure a continuous and stable supply of live bait, it is necessary to establish a "food chain" to cultivate algae and zooplankton, and investing in the establishment of this "food chain" requires a lot of manpower and material resources, and the cultivation of live bait is very difficult in production management, a...
