Advisory Committee
What does ICES advise on?
Single stock advice – how much?
Fishing opportunities for the near future or
How much can you fish next year (In accordance with objectives/strategies)?
Fisheries overviews
Who and How, multispecies advice
Ecosystem overviews
Descriptions of ecosystems, their state and the main pressures
Response to special requests
Ecosystem impacts of fisheries, MSFD, evaluation of management
strategies
Fisheries Overviews
Objective
To provide a concise, up-to-date, evidence-based overview
of the fisheries in each of the ICES ecoregions
includes:
who is fishing, what are they landing
status of the resource (over time)
management measures
Ecoregions
•Who is fishing?
Celtic Seas
Ireland
The Irish fleet constitutes around 600 active ≥10m vessels in addition to
a further XX <10m. Small vessels operating inshore typically target
shellfish with pots or demersal fish with nets. The remainder of the
fleet targets a wide variety of species utilising a number of fleets.
Including large vessel pelagic fisheries across the whole of the area,
Nephrops is an extremely important species to Ireland taken from
grounds in VIIa, VIIg, VIIj, VIIb and VIIck. Demersal fisheries include
trawling for gadoids and slope species, netting to target hake, and beam
trawling for megrim, anglerfish, flatfish and ray species.
