Fisheries biology is a scientific discipline which is focused on the study of fisheries. Fisheries are fish populations which are used for commercial value, and they include saltwater fisheries, freshwater fisheries, and fish farms in both salt and freshwater. Degrees in fisheries biology are offered at fairly few colleges and universities around the world, with both undergraduate and graduate degrees available.

Recent advances in molecular genetics have produced exciting new techniques that can be applied to long-standing problems in fisheries science. The Fisheries Genetics Program bridges the gap between molecular biology and fisheries science, using  molecular techniques to investigate a wide variety of fisheries-related subjects.
