Baited remote underwater video (BRUV) is a system used in marine biology research. By attracting fish into the field of view of a remotely controlled camera, the technique records fish diversity , abundance and behaviour of species.
Also in the assessment, geographical boundaries of different stocks or populations are defined. From the combined biological and fisheries data, the current status and condition of the stock is defined and managers use this assessment to predict how in the future, stocks will respond to varying levels of fishing pressure.
The longline method developed in the 1980s for the effective exploitation of predatory fish e.g. Lates niloticus, Protopterus, Clarias, Bagrus, etc.A typical gear comprises a long length of a mainline 100–300 m (328.08–984.25 ft), rigged with monofilament twine (diameter 1.00-2.00 mm) or multifilament twine (ply 36–60) and bears short snoods 0.3–0.8 m (0.98–2.62 ft) carrying baited ...
Fisheries law is an emerging and specialized area of law which includes the study and analysis of different fisheries management approaches, including seafood safety regulations and aquaculture regulations. Despite its importance, this area is rarely taught at law schools around the world, which leaves a vacuum of advocacy and research.
Fisheries management authorities who make real-time decisions about opening or closing restricted fishing areas are usually on land, and will communicate their decisions on paper, using websites or electronic mail, and by voice radio. Within a vessel monitoring system (VMS), the Fisheries Management Center (FMC) components are on land.
Illegal, Unreported, and Unregulated (IUU) Fishing poses a global challenge and has significant economic and environmental repercussions. [5] The impact of IUU fishing includes economic losses, job losses, scarcity, price distortion, food insecurity and unfair competition, [6] together with the depletion of fish populations and damages to the marine habitat.

NOAA Atlantic fisheries area where VMS must be used. Vessel Monitoring Systems (VMS) is a general term to describe systems that are used in commercial fishing to allow environmental and fisheries regulatory organizations to track and monitor the activities of fishing vessels.
In fisheries and conservation biology, the catch per unit effort (CPUE) is an indirect measure of the abundance of a target species. Changes in the catch per unit effort are inferred to signify changes to the target species' true abundance.
