Problems solved by technology

Existing farms generally use fresh miscellaneous fish and shrimp as feed to breed grouper, which has high cost, high feed coefficient, and is easy to pollute the water quality of the breeding water, resulting in a low survival rate
For this reason, someone has carried out the research of artificial compound feed, and obtained some actual effects, as the Chinese patent CN03114176 etc. of microparticle feed designed for the grouper nursery, but for the grouper adult fish cultivation and the feed that reduces water body pollution haven't seen yet

Abstract

The present invention is one kind of green compounded and puffed feed for rock fish. The green compounded and puffed feed is prepared with steamed fish meal 35-50%, soybean residue 15-20%, pork bone powder 5-12%, beer yeast 3-5%, cuttle fish paste 2-6%, fish oil 1.0-2%, vegetable oil 1-2%, macaroni flour 10-20%, shrimp shell powder 3-6%, lecithin 1-2%, vitamins 0.3-0.5%, compounded mineral 0.5-1% and choline chloride 0.3-0.5%, and through mixing, crushing, extruding to pelletize, and stoving. The green compounded and puffed feed has simple compounding process and balanced nutrients, can meet the requirement of the growth of rock fish, and results in less water contamination.

Description

[Affiliated technical field] [0001] The invention relates to a green and environment-friendly grouper puffed compound feed and a processing method thereof, belonging to the field of compound feed and its processing. [Background technique] [0002] Grouper is a nutritious high-grade banquet food. It has always been loved by people at home and abroad, and its price is getting higher and higher. Therefore, in recent years, the scale of grouper breeding in various places has also increased. The quality of grouper feed is one of the key technologies for the development of grouper aquaculture industry. A good grouper feed should meet the following conditions: good palatability, grouper love to eat; low feed factor, grouper Eat less and grow faster. Existing farms generally adopt fresh miscellaneous fish and shrimps as feed to breed grouper, which has high cost, high feed coefficient, and easily pollutes the water quality of the cultured water body, resulting in low survival rate....
