Fisheries officers are responsible for the conservation and protection of fisheries, whether freshwater or marine. They carry out surveys of aquatic life, investigate fish mortalities and study water quality.
Freshwater fisheries officers conduct field survey work, including surveys of fish stocks and technical project work. They advise members of the public and industry about sustainable fishing and promote angling as a recreational activity.
Marine (or sea) fisheries officers manage, regulate, develop and protect the fisheries and work to sustain the marine environment. This includes inspecting fishing vessels at sea and enforcing technical conservation measures for juvenile and spawning fish.
