Problems solved by technology

[0003] At present, most of the breeding of young Scyllas adopts biological bait such as chilled small miscellaneous fish, shrimp and shellfish (such as clams and mussels) as feedstuffs. However, young Scyllas have immature digestive tracts and digestive enzymes Physiological characteristics such as low activity, and the biological bait is difficult to store, and the nutritional quality is easily affected by factors such as changes in the environment and the type of biological bait (such as different types of chilled fish), which leads to the survival rate and feed conversion rate of young crabs. It has become one of the main obstacles for the production of blue crabs to have a major breakthrough. At the same time, problems such as marine environmental pollution caused by feeding biological baits have aroused widespread concern from government departments.
