Problems solved by technology

Crab and shrimp farming requires a large amount of feed and ice fish. The production cost of inputs is high, and the ponds are prone to water damage, resulting in a low catch rate of crabs and shrimps, which eventually leads to poor harvests or even losses.

During production, the components of each raw material should meet their respective quality requirements, and the error of component measurement accuracy during preparation is less than ±0.5%. Take each component as a raw material and stir evenly. The product is generally made into a powdery or granular mixture, with no peculiar smell, no agglomeration, mildew, moth, and foreign matter. Moisture should not be higher than 18%.

Embodiment 3

[0022] Production of bait biological medium, specific formula: red nematode (water earthworm) eggs 0.5kg, soybean polypeptide 8kg, soybean meal 360kg, bran 219kg, rice bran 190kg, fermented chicken manure 160kg, sodium humate 50kg, compound mineral salt 12.5kg, A total of 1000kg. During production, the components of each raw material should meet their respective quality requirements, and the error of component measurement accuracy during preparation is less than ±0.5%. Take each component as a raw material and stir evenly. The product is generally made into a powdery or granular mixture, with no peculiar smell, no agglomeration, mildew, moth, and foreign matter. Moisture should not be higher than 18%.

[0023] In the above examples 1-3, the trace elements contained in every 1 kg of composite mineral salt are: K≥8g, Mg≥12g, Cu 0.4~2g, Fe≥20g, Zn 12~30g, Mn≥2g, Co≥200g, I≥ 200g, Se≥0.03g.

Abstract

Disclosed are biological bait culture media and a method for cultivating tubificidae to breed crabs and shrimps by the aid of the biological bait culture media. The 1000kg of culture media comprise 0.5kg of tubificidae egg mixture, 8+ / -0.5kg of soybean peptide, 350+ / -10kg of bean pulp, 209+ / -10kg of bran, 200+ / -10kg of rice bran, 50+ / -1kg of sodium humate, 170+ / -5kg of fermented chicken droppings, and 12.5+ / -1kg of compound mineral salt. The method for cultivating tubificidae to breed crabs and shrimps includes steps of 1), selecting a pond; 2), uniformly paving the bait culture media on the bottom surface of a pond; 3), feeding water in the pond by 20 centimeters and then planting waterweed, hydrilla varticillata and eel grass; 4), breeding crab seeds or shrimp seeds or freshwater shrimpseeds in open air; and 5) selectively arranging a micropore automatic aerator according to the size of the breeding pond. The biological bait culture media and the method meet natural feeding habit of the crabs and the shrimps, greatly increase growth speed of the crabs and the shrimps, reduce cultivation cost, and are suitable for integral breeding of the crabs and the shrimps.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to a method for cultivating red nematodes, i.e. water worms, for cultivating crabs and shrimps. Specifically, modern biotechnology is used to prepare bait biological culture medium, and a new production method for cultivating crabs and shrimps is designed. Background technique [0002] It takes two years to grow crabs and shrimps in ponds. In the first year, crabs and shrimp seedlings are cultivated into crabs and shrimp species (young crabs and shrimps), and in the second year, crabs and shrimp species are cultivated into crabs and shrimps. (commodity crab, shrimp) listed. Now that people's living standards have improved, pollution-free crabs, shrimps, organic crabs, shrimps, etc. have become popular products. Crab and shrimp farming requires a large amount of feed and ice fish. The production cost of inputs is high, and the ponds are prone to water damage, resulting in a low catch rate o...
