Abstract

The invention discloses a compound artificial feed for scylla paramamosain. The feed comprises the following components in parts by weight: 300-400 parts of fish meal, 300-380 parts of expanded soybean meal, 20-30 parts of soybean oil, 10-20 parts of fish oil, 30-40 parts of rice bran, 30-40 parts of wheat bran, 40-50 parts of corn flour, 5-10 parts of spartina alterniflora powder, 2-5 parts of fly maggot powder, 35-45 parts of alpha-starch, 0.1-0.3 part of beta-glucosidase and 20-30 parts of an additive. The feed disclosed by the invention can replace iced fresh fish baits, balanced nutritional structure and good palatability are ensured, and digestive enzyme activity and immunity of scylla paramamosain can be improved to a certain extent. The feed does not contain any antibiotics, chemical synthetic drugs and the like.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a compound artificial feed for mud crabs. Background technique [0002] Scylla paramamosain belongs to the warm-water wide-saline marine crabs of the family Portunidae. It has the characteristics of fast growth, large individual, and strong adaptability. The maximum individual weight can reach 2 kg. Its meat is delicious and has high nutritional value. It is a traditional rare seafood and has become one of the main marine cultured crustaceans in recent years. At present, the breeding of blue crabs still mainly relies on fresh and live bait, and the lack of nutritionally balanced feed has become a bottleneck hindering the sustainable development of blue crab farming. As an invasive alien species, Spartina has high nutritional value. If it can be used in the diet of mud crabs, it can broaden the application of Spartina. Therefore, it is important to develop a kind of artifici...
