The spawning-stock biomass (SSB) for this stock has been increasing since 2005 and is now estimated to be the highest in the time series and above MSY Btrigger. Fishing mortality (F) is now at FMSY. Monkfish or angler species are vulnerable to over-exploitation as they are long-lived and late to mature. Also of concern is that 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.
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 - 90 cms, males at around 6 years at 50 cms. Females can attain a length of 2 m and a weight of 40 kgs. Males rarely grow beyond 1m. Two species occur in most areas, L.piscatorius (white) and L.budegassa (black-bellied), although catches are almost exclusively of the former. There is general consensus amongst scientists that there is one stock of L.piscatorius 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 1,000 m. Eggs are released in a buoyant, gelatinous ribbon or ‘egg veil’ that may measure more than 10 m in length. Anglerfish are also found in coastal waters.

Southern Celtic Seas, Bay of Biscay
This is the first time since 2006 that ICES has provided advice based on an analytical assessment of this stock.
The spawning-stock biomass (SSB) for this stock has been increasing since 2005 and is now estimated to be the highest in the timeseries. Fishing mortality (F) has been above FMSY but has trended downwards since the mid-2000s and is now at FMSY. Recruitment has been variable over the time-series. ICES assesses that fishing pressure on the stock is at FMSY and below Fpa and Flim, and that the spawning stock size is above MSY Btrigger, Bpa and Blim.
ICES advises that when the MSY approach is applied, catches in 2019 should be no more than 31 042 tonnes.

There is currently no agreed precautionary management plans for anglerfish (L. piscatorius) in this area. The two species (L.piscatorius and L. budegassa) are landed together with landings of L.piscatorius representing around 70% of the total. A single TAC covers both species and species-specific landings are estimated by ICES. Management of the two anglerfish species under a combined TAC is inadequate and prevents effective control of single-species exploitation rates and could potentially lead to over-exploitation of either.
ICES recommend that management for L. piscatoruis and L. budegassa should be combined, in conjunction with other species that are caught in this fishery (multi-species management).
Anglerfish are subject to significant fishing mortality before attaining full maturity, and most of the anglerfish catch consists of immature fish. 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. Discards were estimated at 8% in 2017. The European Commission has proposed a multiannual management plan (MAP) for the Western Waters, which is not yet finalized.

20% of the total landings of monkfish from this stock in 2017 is gillnetted. Tangle netting is a more selective fishing method to catch monkfish (or anglerfish) and turbot. Nets have a minimum mesh size of 22cm (or 10.5”) so only land tails from bigger fish. In Cornwall, these vessels account for 30% of the annual catch of monkfish or anglers. Bycatch of marine mammals and other non-target species can be problematic in fixed-net fisheries. However, use of management measures, including acoustic devices called ‘pingers’, can help reduce bycatch of marine mammals. See Fishing Methods for more details.
