Abstract
The invention provides a safe high-efficiency fully-cooked feed for artificially and ecologically culturing river crabs. The feed comprises the following components in percentage by weight: 15-22% offish meal, 4-8% of meat powder, 2-4% of spray-dried blood cells, 20-28% of fermented soybean meal, 10-18% of double-low rapeseedmeal, 12-18% of wheat flour, 6-9% of rice bran, 2-2.5% of soybean oil,1.5-2% of calcium dihydrogen phosphate, 1% of a river crab composite premix, 0.1-0.2% of a feed attractant, 0.04-0.06% of VC-monophosphate, 0.05-0.08% of L-carnitine and 0.08-0.1% of ecdysone. The feed disclosed by the invention has the advantages of safe raw material source, no pollution to culture water, reasonable cost, high culture efficiency, low ecological environment damage and reasonable nutritioncollocation. Requirements of environmental protection and sustainable development can be achieved on the premise that the yield and culture quality of river crabs are ensured.
Description
technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a safe and efficient full-cooked feed for artificial ecological cultured crabs. Background technique [0002] With the continuous development of social economy, people's demand for high-quality aquatic products is also increasing. For example, the popular river crab is one of them. The breeding quality of aquatic products is closely related to water sources, breeding methods and feeding feed. At the same time, due to increasingly stringent environmental protection requirements and the purpose of sustainable development, the breeding process of aquatic products should also avoid pollution to water bodies. At present, the river crab farming in my country is mainly based on the traditional extensive culture mode of feeding corn, wheat, and chilled fish. The feed utilization rate of this mode is low and the cost is high; The ability is low, the survival rate of juvenile crab...
