Problems solved by technology

[0004] At present, the cultivation of grouper fry in China mainly relies on natural baits such as chlorella, rotifers and artemia, which are expensive, cumbersome to operate, and easy to pollute water quality. At the same time, pathogens such as parasites, bacteria and viruses may be introduced. The instability of quality also brings inconvenience to the cultivation of grouper fry openings
Some other feeds manufactured by existing technology cannot be selected according to the growth and physiological digestion characteristics of grouper fry, and the production process is also very easy to destroy nutrients, resulting in low utilization rate of these feeds, easy to pollute water quality, not suitable for Large-scale Production and Cultivation of Grouper Seedlings

Abstract

The invention discloses grouper fry larval stage feed and a preparing method thereof. According to the grouper fry larval stage feed, feed raw materials which are easy to digest and absorb, high in utilization rate and strong in food calling are chosen according to growing and physiological digestion characteristics of grouper fry in larval breeding stage. Meanwhile, micronutrients of vitamin and mineral elements are reinforced, the metamorphosis development of the fry is prompted, the growing performance is improved, and disease resistance and stress resistance of the fry are improved. The grouper fry larval stage feed is reliable in raw material source, stable and safe in quality, convenient to feed and suitable for grouper fry cultivation in scale. In addition, the grouper fry larval stage feed overcomes the defects that natural feed is high in cost, prone to polluting water quality, unstable in quality and prone to bringing pathogeny of parasite, bacteria and virus.

Description

Technical field: [0001] In the field of aquaculture, the invention specifically relates to an open bait for grouper seedlings and a preparation method thereof. Background technique: [0002] my country's artificial compound feed has been applied to a variety of freshwater fish such as carp, grass carp, bream, tilapia, rainbow trout, eel, etc. Some species such as eel, carp, tilapia, etc. Achieved serialization. In recent years, the production of compound feed for seawater fish has also developed rapidly, and soft pellet feed and sinking pellet feed formulated with powder have developed into extruded pellet feed. However, there are still many problems in the nutrition research of seawater fish and the research and development of artificial compound feed in my country, and there is still a big gap compared with foreign developed countries. In particular, the basic research on the nutritional and technical aspects of the artificial compound feed for larvae and juvenile fish is...
