A fisheries technician is a biologist who surveys the fishing, aquaculture, and fish hatchery industries. As a fisheries technician, your duties include a number of scientific tasks, such as monitoring fish breeding, dissecting and analyzing specimens that have been caught by commercial fishers, tagging fish so they can be tracked, ensuring the preservation of a marine habitat and environment, and looking out for threats like disease and overfishing that may affect aquatic populations. To complete your duties, you use unique measuring and observational equipment, such as the fish wheel and passive integrated transponder tags.
