The Influence of Sex, Size, and Season on Mirex Levels within Selected Tissues of Lak
By S.E. Insalaco, J.C. Makarewicz, J.N. McNamara
Journal of Great Lakes Research, Volume 8, Issue 4, 1982, Pages 660-665, ISSN 0380-1330, DOI: 10.1016/S0380-1330(82)72005-2.
Statistical comparisons were made for mirex concentration in whole fillet, red muscle, belly flap, skin, dorsal loin, and caudal peduncle between sexes in coho (Oncorhynchus kisutch) and chinook (O. tschawytscha) salmon collected from Lake Ontario during the spring and autumn. These data were also correlated with season, sex, and weight. Comparisons of mirex concentrations between skin, belly flap, and whole fillet and between dorsal loin and caudal peduncle were not statistically different. Significant differences in mirex concentrations were found between groups for (A) belly flap/skin/whole fillet tissue group, (B) red muscle tissue, and (C) the dorsal loin/caudal peduncle tissue group with concentrations decreasing from group A to group C. In general, mirex concentrations (mg/kg) increase with individual fish weight and appear to parallel reported lipid concentrations for similar tissues. Although no discernable pattern was evident, concentrations of mirex were observed to be significantly different between sexes or seasons in some tissues.
