Yellowtail, Seriola quinqueradiata

More in-depth profiling of the in vitro hepatic metabolism of diazinon was carried out in carp, dace (Tribolodon hakonensis), channel catfish, rainbow trout and yellowtail (Seriola quinqueradiata)2S. All fish were able to catalyze the desulfuration of diazinon to the oxon. In freshwater fish, the predominant metabolites were isopropenyl diazinon and hydroxypyrimidine. In the carp, dace and catfish, hydroxy diazinon was observed, while hydroxymethyl diazinon was the major metabolite in the yellowtail. In rainbow trout and catfish, isopropenyl diazoxon was observed. In the freshwater fish, more than 70% of diazinon was converted to metabolites with 50% of the metabolites being the nontoxic hydroxypyrimidine. However, in yellowtails, more than 70% of diazinon remained as toxic P-containing esters including the oxon. It was hypothesized that yellowtails had approximately 50% of the CYP levels of carp and rainbow trout and were not capable of converting diazinon to the other metabolites.
