A fisheries biologist specializes in the study of fish and management of natural and environmental factors that impact fisheries. They can either work in conservation, for a government or non-profit organization, or in the commercial sector. Your workplace and goals may vary by employer, but many of your duties remain the same. As a fisheries biologist, your responsibilities include conducting experiments, collecting wildlife and environmental samples, and studying everything regarding fish from population to migration. You use the data you collect to collaborate with a team of professionals from varying backgrounds to determine what factors are impacting marine life. Depending on the sector in which you work, you may advise on environmental regulation proposals to help maintain fishery populations.
