Nibea albiflora juvenile fish compound feed with fish meal replaced by fermented soybean meal and feeding method

Abstract

The invention provides Nibea albiflora juvenile fish compound feed with fish meal replaced by fermented soybean meal. The compound feed is prepared from, by weight, 14-70 parts of fish meal, 10-67 parts of fermented soybean meal, 1-6 parts of fish oil, 1-6 parts of soybean oil, 5-13 parts of dextrin, 0.5-2.5 parts of soybean lecithin, 0.2-1.6 parts of seawater fish compound premix feed, 0.1-0.6 part of choline chloride, 0.5-2.0 parts of monocalcium phosphate, 0.05-0.2 part of hydroxyl methionine, 0.02-0.08 part of ethyoxyl quinoline and 0.3-15 parts of cellulose. Compared with the prior art, on the premise of not affecting healthy growth of juvenile fish, the use amount of the fish meal can be reduced to about 43% or even about 25%, and feed cost is greatly reduced. The protein source amino acid is balanced, the compound feed is high in palatability, and beneficial for fish feed ingestion and feed digestion and absorption, and it is proved through experiments that the feed can ensure healthy growth of the juvenile fish.

Description

technical field [0001] The invention relates to a compound feed for juvenile yellow croaker fish with fermented soybean meal instead of fish meal and a feeding method. Background technique [0002] yellow croaker ( Nibea albiflora Richardson ), belonging to Perciformes, Totoabaidae, croaker genus, warm-temperature inshore middle and lower layer fish, mainly distributed in the Northwest Pacific, and distributed in the South China Sea, East China Sea and Yellow Sea. It has delicious meat, rich nutrition, rapid growth, and few diseases. It can reach the market standard of commercial fish in the same year of breeding, and has become a new species with great development potential for marine fish cage culture. [0003] In the current croaker farming, the main method is to feed chilled small miscellaneous fish or use compound feed containing a large amount of fishmeal, which not only has a high feed coefficient, pollutes the breeding environment, but also has high breeding costs. ...

Problems solved by technology

[0008] However, in the above two groups of compound feeds, although the amount of fish meal has decreased, other protein sources such as spray-dried hemoglobin powder, hydrolyzed fish protein powder, shrimp shell powder, etc. are used, and the palatability of the feed may be relatively poor. May affect fish's feed intake and digestion and absorption of feed
