Term Description
Access right A right to carry out specified fishing   activities.
Bycatch Bycatch includes all material, flora and fauna,   living or not, which is not the intended species of the catch. It doesn’t   usually include species which is caught but doesn’t actually reach the deck   of the boat …but has nevertheless been affected or killed by the fishing   gear.
By-product Non-target species which has been caught and/or   sold by the fisher
Danish seine A trawling method in waters usually up to about   200 m. A Danish seine, also occasionally called an anchor seine, consists of   a conical net which encircles an area, herds and scoops everything into the   net.
Danish seiners are most effective on demersal fish which are close to the   bottom of the sea.
Demersal fish Fish which are found on or near the seabed.
Demersal trawl Trawler which is designed to trawl the sea bed.   It is fishing for demersal species on or near the bottom.
Discards Any fish caught which is thrown overboard alive   or dead.
FIFO Ratio Fish in :Fish out ratio. Aquaculture industries use   this ratio to express their efficiency. E.g. A ratio 5 means it takes 5 kg of wild fish protein to   produce 1 kg of aquaculture fish. Hardly efficient.
Fishing capacity The total fishing capability of a boat or group   of boats if fishing effort was maximised to full its full potential
Handline A line which has one or more baits attached. It   is not a mass-catch technique.
Longline fishing A Longline can be used on the surface-set   (pelagic) or bottom-set (demersal). The main line can have multiple branch   lines attached to it which are each fitted with one or many baits attached.   These longlines can extend several kilometres. Several billion hooks are set   each year in this fashion.
Mid-water trawling Trawling where the net does not touch the seabed.   The fish targeted are pelagic and semi-pelagic fish which are in schools.
Net Consumer An example of a Net Consumer is farmed salmon,   where, according to Aquaculture figures, the FIFO ratio (see above) is 4.9. That means it takes 4.9   kg of wild fresh fish to produce 1 kg of farmed salmon. The salmon industry is   therefore a NET CONSUMER of fish. It   consumes more than it produces.   This is currently the case for all types of farmed fish.
Net Producer A farming/manufacturing process which produces more than it consumes from wild stocks.
Non-target Species Any fish which have been caught but were not the   intended species. This includes by catch and by-product.
Pelagic fish Fish that are normally caught on the sea surface   or mid water.
Poling (pole-and-line fishing) A fishing method using a short pole with a   barbless lure or a baited barbless hook attached to a short trace to hook and   swing pole the targeted fish back onto the boat.
Purse-seining An area of water is surrounded by a net which is   set at the surface which is then enclosed at the base
Rendered This is the process which takes wild fish protein   and converts it into fish pellets and an oil by-product. The fish pellets   then become animal feed.
Sustainable yield The amount of catch which could reasonably be   removed from fish stocks without creating a future reduction in the biomass   of that fish stock. It does not necessarily permit RECOVERY of fish stock   numbers.
Target Species The intended species of the catch
Total Allowable Catch (TAC) A TAC is the permitted mass of a species of fish   which is allowed to be caught from a fishery within a defined period.
