Determination Of Cholinesterase Activity In Tiger Shrimp And Giant Perch(การวิเคราะห์หาสมรรถนะของเอนไซม์ โฆลีนเอสเทอเรสในกุ้งกุลาดําและปลากะพงขาว), Supatra Srichairat

The Thai Journal of Veterinary Medicine

The conventional colorimetric method of cholinesterase activity determination in blood and tissues of mammals was applied to investigate the enzyme activity in muscle and nervous cell of aquatic animals which are economically important, such as, tiger shrimp (Penaeus monodon fabricus) and giant perch (Lates calcarifer). Decreased enzyme activity in aquatic animals may indicate the contamination of insecticide in water resources. This study demonstrated that the method was suitable for detecting toxicity of organophosphate insecticide due to its convenience, simplicity and no sophisticated or expensive instruments needed. Moreover, the samples can be kept frozen for 2 weeks before analysing with less …
