Lipids and specifically fatty acids acquired by female fish through their diet are deposited into their eggs and will ensure survival, development and growth of their offspring. The availability of these nutrients may differ among lakes because of food web differences. Therefore, the objective of this study was to compare lipids (total, neutral and phospholipids) and fatty acids profiles in lake trout eggs from the Great Lakes, Cayuga Lake and Lake Champlain over a two year period (2009 and 2010). Our results indicate differences in fatty acid signatures among lakes reflecting potential food web differences in these lakes. Discriminant function analysis was performed on fish eggs from 13 samples sites using the 18 most abundant fatty acids detected in both lipid fractions. Overall classification success was 77.7% and 77.3% for the NL and PL fraction, respectively.
