Problems solved by technology

[0003] At present, biological bait such as chilled small miscellaneous fish, shrimp, and shellfish (such as meretrix meretrix and mussels) is mostly used as feed for the breeding of adult crabs, but the biological bait is difficult to store, and its nutritional quality is easily affected by the environment and the type of biological bait. Changes (such as different types of fresh fish) and other factors, resulting in low survival rate of adult crabs and low feed conversion rate, which has become one of the main obstacles for the production of blue crabs to make a breakthrough. At the same time Problems such as marine environmental pollution caused by feeding biological bait have aroused widespread concern from government departments
