Drug Research Information Bulletin - Efficacy of Terramycin® 200 for Fish (Oxytetracycline Dihydrate) for the Skeletal Marking of Rainbow Trout Oncorhynchus mykiss

In the study, rainbow trout served as a representative freshwater-reared salmonid species. To demonstrate efficacy, the study protocol specified that the mean percentage of rainbow trout with marked vertebrae in TM200-treated tanks had to be equal to or greater than 70%.
