Tóm tắt

Mud crabs (Scylla olivacea) have been studied to investigate the effect of active ingredient 20-hydroxyecdysone (20-E) on their molting stimulant. The amount of 20-E added was assessed by body weight, molting stimulant and viability of a group of crabs. The results showed that the content of 40-60 ng/100 grams of feed applied to 20 breeds was the best to help reduce the molting stimulant of crabs while ensuring the highest survivability. The LC-Orbitrap liquid chromatography method is suitable for analyzing residues of 20-E compounds in mud crabs with basic parameters in accordance with AOAC requirements given about the analytical concentration range. 20-E compound residues are proven to be backlog after use. Groups with the optimal 20-E content have the smallest fluctuation in residues. Therefore, it is necessary to adhere to the appropriate molting levels in mud crab culture
