Fishery-independent data is obtained in the absence of any fishing activity. The majority of this data is collected by state and federal agencies. A wide variety of methods and gear types are used to acquire fishery-independent data. Sampling equipment can include trawls, seines, acoustic and/or video surveys. The study may focus on a single ...
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.
Satellite imagery is responsible for the large majority of monitoring and surveillance in the area around West Africa. [5] Low-flying aircraft can visually identify fishing vessels, and, with reasonable navigational skills, determine whether a given craft is in an authorized area. This is aided if the fishing craft display distinctive identifiers.
Fisheries management, including limited VMS, is under the Marine and Coastal Management (MCM) organization in the Department of Environmental Affairs and Tourism. [66] Hake Merluccius spp.) trawl fishery is the mainstay of South Africa's fishing industry, and the center of regulatory efforts. On-board observers had been the mainstay of ...
Traditional methods for fishery assessment can be highly destructive, such as gillnet sampling or trawling. Molecular methods offers an alternative for non-invasive sampling. For example, barcoding and metabarcoding can help identifying fish eggs to species to ensure reliable data for stock assessment, as it has proven more reliable than ...
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.
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.
Fisheries acoustics includes a range of research and practical application topics using acoustical devices as sensors in aquatic environments. Acoustical techniques can be applied to sensing aquatic animals , zooplankton , and physical and biological habitat characteristics.
