AI Technical Summary

Problems solved by technology

Shrimp and crab carapace canker will significantly reduce the yield and quality of commercial shrimp and crab, and farmers will suffer heavy losses

When farmers treat crustacean ulcer disease, they usually use external splashing of disinfectants and substrate modifiers and oral antibiotics. Oral antibiotics such as florfenicol are likely to cause drug resistance in shrimp and crabs and cause food damage due to drug residues. safe question
