The Effect of Highly Unsaturated Fatty Acids (HUFAs) on Early Life Stage Lake Trout Alevins Using Artemia Nauplii Enriched with Commercial Emulsions

Highly unsaturated fatty acids (HUFAs) play an important role in fish survival, development, growth, and reproduction. The objective of this experiment was to evaluate the effect of HUFAs on lake trout alevins using three diets; diet 1, Artemia nauplii; diet 2, Artemia nauplii enriched with SELCO (200 mg/g HUFA); and diet 3, Artemia nauplii enriched with Super-SELCO (400 mg/g HUFA). After eight weeks, fish were sampled for survival, growth rate, whole body lipids, and fatty acid profiles. Results show that lake trout alevins fed Artemia enriched with SELCO or Super-SELCO outperformed alevins fed non-enriched Artemia. Alevins fed easy SELCO or easy Super-SELCO enriched Artemia displayed higher final length, final weight, weight gain, and total body lipids than alevins fed non-enriched Artemia. However, there were no significant differences observed between alevins fed the SELCO or Super-SELCO diets. This research serves as the basis for my MS thesis.
