Increasing Frequency of Thryroid Goiters in Coho Salmon (Oncorhynchus kisutch) in the Great Lakes
Moccia RD, Leatherland JF, Sonstegard RA. 1977. Increasing Frequency of Thryroid Goiters in Coho Salmon (Oncorhynchus kisutch) in the Great Lakes. Science. 198(4315):425-526
Coho salmon collected during the 1976 spawning runs from Lakes Michigan, Ontario, and Erie had overt goiter frequencies of 6.3, 47.6, and 79.5 percent, respectively. These represent significant increases over the frequencies observed in previous years. Epizootiological data suggest that environmental goitrogens (possibly pollutants) may be involved in the etiology of the thyroid disorder.
