Abstract
Odd-chain fatty acid (OCFA) levels in rainbow smelt (Osmerus mordax) from Jeddore Harbour, N.S., showed a pronounced seasonal variation during the period from spring 1969 to fall 1970, reaching a maximum of 20% total fatty acids in the January–March period, and falling to a minimum of approximately 2% total fatty acids in summer and fall. The variation appeared to be general, and occurred in all OCFAs. Analysis of smelt stomach contents suggested that OCFAs originated in the diet. Smelt caught in inlets adjacent to Jeddore Harbour showed no unusual accumulation of OCFAs in January, 1970.Keywords
