Available in PDF, EPUB and Kindle. Book excerpt: Oxytetracycline, as TM-50, was fed to rainbow, brook and brown trout held at three temperatures, 6-7 degrees, 9-10 degrees, and 12-13 degrees centigrade. Tissues were assayed to determine excretion rates. The greatest concentration was found in the liver, then muscle, plasma, and kidney. Residues were undetectable in the muscle, plasma, and kidney after 10 to 14 days at 12-13 degrees centigrade, and in the muscle at 9-10 degrees centigrade, but 4 weeks were required for these tissues to clear at 6-7 degrees centigrade. Liver took 30 days to clear at 12-13 degrees centigrade. More than 35 days were required at 6-7 degrees centigrade. Cooking generally destroyed the residues in the muscle.
