Sustainability overview

The state of the stock, comprising both white and black-bellied anglerfish, in this area is unknown, but thought to be stable in the long-term. Stock trends show an increase in recent years. The monkfish or angler species are vulnerable to over-exploitation as they are long-lived and late to mature. Also the majority of the catch, particularly in trawl fisheries, consists of immature fish. To increase the sustainability of fish eaten from this stock, ensure fish is above or equal to the size at which it matures - at least 70cms. Choose gillnet caught fish where available. The C&WSTG English Channel megrim, monk and sole beam trawl fishery is currently being assessed against the Marine Stewardship Council (MSC) standard.

Biology

Anglerfish are so called because they possess a fishing lure at the tip of a specially modified dorsal ray, with which they can entice prey. They are a long-lived species. Maximum reported age is 24 years.Females mature at 9-11 years at about 70 - 90cm, males at around 6 years at 50cms. Females can attain a length of 2m and a weight of 40kgs. Males rarely grow beyond 1m. There is general consensus amongst scientists that there is one stock and that this spawns in spring and early summer, in deep water off the edge of the continental shelf to the west of Scotland, in waters down to 1,000m. Eggs are released in a buoyant, gelatinous ribbon or 'egg veil' that may measure more than 10m in length. Anglerfish are also found in coastal waters. Two species occur in most areas, L.piscatorius (white) and L.budegassa (black-bellied), although catches are almost exclusively of the former.

Stock information
No analytical assessment is available for this stock and reference points are not defined. The long-term trend for both species caught in this area is stable. For L.piscatorius the average indicator of stock size in the last two years (2011-12) is 55% higher than in the previous three years (2008-10). ICES advises that landings may be increased by 20% and should be no more than 37,450 t in 2014.

Management

Capture information

Large proportions of the catch comprise young fish which have not yet reached maturity. Juvenile fish are easily retained by the minimum mesh size in force and often discarded. There are indications that discarding has increased in recent years. Because of its body shape, large head and jaw, the introduction of a minimum landing size for these species is not considered a useful or practical management measure. However, recent EU marketing standards fixed a minimum weight of 500g for anglerfish. There is potential for damage to the seabed by trawling. Trawling is also associated with discarding of unwanted fish, i.e. undersized and/or non-quota and/or over-quota species. Recently there has been increased enforcement of anglerfish quotas.
