The ICES Statistical Areas delineates the divisions and subdivisions of FAO Major Fishing area 27

The ICES Statistical Areas delineates the divisions and subdivisions of FAO Major Fishing area 27. The ICES Statistical Areas are used as bounding areas for calculation of fish statistics, e.g. catch per unit effort (CPUE) and stock estimates.

The dataset includes age- and length-based catch per unit effort data for commercial fish species in ICES roundfish areas.

Annual statistics for commercial fishing activity by UK registered fishing vessels for the year indicated. Statistics are provided for the North East Atlantic (FAO Major Area 27) to ICES statistical rectangle level by fishing gear and vessel length on: fishing effort (kilowatt/days), landings by value (pounds sterling), landings by live weight (tonnes), number of vessels (this information may be omitted from published versions). Gear types are shown at the level of the International Standard Statistical Classification of Fishing Gear (ISSCFG) and also aggregated into different groups to allow analysis at different levels.

The data product includes three folders:

Fishing footprint coordinates - Maps in a pdf-file and coordinates in a csv-file of three fishing footprints; 1) combined, 2) static gears and 3) mobile bottom-contacting gears. VME-likely-VME coordinates - Maps in a pdf-file and coordinates in a csv-file of the closure scenarios/options. Each csv-file also indicates the VME habitat, VME indicator and VME physical element data present in each closed area scenario/option, as well as, the VME habitat and index C-squares. Maps interactive - Two interactive maps (Interactive Map 1 and Interactive Map 2) and a Read-me pdf-file that explains how to open and use these maps.

ICES work is centred on the North Atlantic Ocean as well as the adjacent North Sea and Baltic Sea and is carried out in a collaborative and coordinated manner by the laboratories and institutes of the 20 ICES Member Countries.

Annual nominal catches of more than 200 species of fish and shellfish in the Northeast Atlantic region. Data are presented in the live weight equivalent of landings per year, country, species, and fishing area. This dataset includes catches starting from 2006.

This dataset summarises stock assessment advice for quota fish stocks and national shellfish stocks. These files contain data quantifying annual recruitment, biomass, stock size, landings, catches, discards, industrial bycatch, fishing pressure (fishing pressure mean, ranges, and estimated pressure accountable to landings, discards and bycatch) and stock indicators (Flim fisheries mortality that if exceeded would result in the stock falling below Blim, Blim spawning stock Biomass at the limit reference point, Fpa level of catches that if exceeded would result in the stock falling below Bpa, Bpa spawning stock Biomass in relation to the precautionary approach, Fpa FMSY Maximum sustainable yield, BMSY Maximum sustainable yield biomass trigger) for various fish stocks (fish species in given ICES regions).

This dataset describes fishing intensity for Otter mobile bottom contacting gear in 2011 based on VMS/Log book data processed by ICES Working Group on Spatial Fisheries Data (WGSFD).

ICES secretariat collected during 2017 relevant VMS and logbook data for 2009-2016 to produce, as a technical service to HELCOM, updated spatial data layers on fishing intensity/pressure. Improved data quality control checks were implemented. Submitted data across the HELCOM area have improved in quality compared to previous data 2009-2013 published in 2015. Standardized methods were used to produce the requested data layers. The code used to create the data products is available here: https://github.com/ices-eg/wg_WGSFD

The ICES programme of international herring larval surveys in the North Sea and adjacent areas is in operation since 1967. The main purpose of this programme is to provide quantitative estimates of herring larval abundance, which are used as a relative index of changes of the herring spawning‐stock biomass in the assessment. The larvae surveys are carried out in specific periods and areas, following autumn and winter spawning activity of herring from north to south. Catch data together with specific information like haul position, survey area etc. are reported to the ICES International Herring Larvae database annually. The database contains information about the surveys conducted since 1972. The ICES responsible group for the dataset is WGIPS.

The dataset includes age- and length-based catch per unit effort data for commercial fish species collected during the Irish Ground Fish trawl survey.

EngDescr=Fisheries Science Services (FSS) carries out the annual Irish Groundfish Survey (IGFS) in the fourth quarter of each year as part of a larger coordinated survey effort with our EU neighbours (France to the south; and the UK to the north).

A broad spectrum of data is collected during the survey, but the overriding objective is to provide information on commercially exploited fish stocks. In particular the survey provides an index of the proportion of juveniles in the stock, which in turn gives an indication of its spawning success. This is an important source of information not available from commercial landings due to the necessary minimum fish length restrictions on commercial catches.

In addition, the survey provides data on species and environmental parameters in areas of both high and low commercial activity. This gives a better context to data for the entire survey area as opposed to focusing entirely on traditional fishing hot-spots that can remain stable while significant changes in surrounding background abundance and distribution go un-noticed.

The primary goal of the groundfish survey is to develop estimates of juvenile abundance for important species. Measurements of the abundance of juvenile fish are a critical measure of the health of a stock, serving as an annual indication of recruitment (the number of newly spawned fish which enter the population each year) success or failure. Most importantly, they allow forecasting of future commercial abundance.

Survey provides data on the distribution and biology of commercial and non-commercial species of ecological interest, as well as hydrographic and environmental observations. When these data are combined with annual recruitment indices they can help identify the possible causes driving year-class success or failure, and allow us to see long-term changes in populations that may have been caused by fishing, pollution, or climate change. This spatial dataset comprises the haul station location from the trawl survey. The Irish Groundfish Survey feeds into the International Bottom Trawl Survey [ie. IBTS] for international reporting.

The Irish West Coast Groundfish Survey started in 1990 and for the first two years consisted of circa 25 stations concentrated around the Irish coast in ICES Areas Via South and VIIb. Adverse weather in 1992 limited station coverage to only 4 stations which effectively broke the time series.

The survey was re-established in 1993 and has consisted of circa 70 stations, for Parts A and B combined, since then. Spatial coverage was extended west out to the 200m contour, but remains as Via South and VIIb.

Due to the restrictions of the current and previous research vessel commercial trawlers have been contracted to carry out the survey work. Wherever possible continuity of vessel and gear has been maintained and standard IBTS methodology applied. However, due to reduced staffing on commercial vessels it has rarely been possible to completely sort the catch.

Until 2000 all cod were sorted from the catch and then a sub-sample of two baskets was taken and completely sorted. From 2001 onwards, in response to an overall review of survey sampling undertaken during the IPROSTS Project (Anon 2001), the catch is completely sorted for all target species and a qualitative assessment made of the residual catch as a minimum.

The Irish surveys use an ICES rectangle based sampling strategy. The sampling design attempts to allocate at least two stations per rectangle (where the sea area is appropriate). Stations are selected randomly within each rectangle from known clear tow positions.

On the WCGS and ISCGS circa 70 fishing stations are planned on each survey every year. The number of hauls is adjusted according to the ship time available at sea.

The Irish West Coast Groundfish Survey is carried out in two parts: Part A covers ICES Division Via (south) and VIIb (north); Part B covers ICES Division VIIb and VIIj. The survey is conducted from 15 to 300 m depths during the fourth quarter (October - November). The Irish West Coast Groundfish Survey is carried out on chartered commercial fishing vessels. Whilst the same vessel (MFV Marliona, 224 gross tonnage and 30 m LOA) has normally been used each year for Part A and Sionann for Part B, in 2001 Part B was conducted from the MFV Regina Ponti (34.5 m LOA). Both vessels use a Rockhopper net with 12 inch discs and 11 inch Thyboron doors. The nets are fitted with a 20 mm codend liner. Gear performance throughout the survey is monitored using Furuno Ch24 (Headline Monitor).

The Irish Sea Celtic Ground Survey commenced in 1997 and evolved from an earlier Irish Sea Juvenile Fish Survey. As a consequence early survey stations concentrated largely, though not exclusively, around a number of shallow spawning areas along the Irish east coast in VIIa. These positions were expanded in combination with clear tows provided by the industry and CEFAS as well as some exploratory tows.

Spatial coverage therefore extended into the western Irish Sea from 2001 into the area around the Isle of Man, Liverpool and Cardigan Bays and the Welsh coast. The survey is carried out on the Irish research vessel the R.V. Celtic Voyager.

The sampling procedure on board conforms to the IBTS standard protocols and as such all cod are sampled and aged, the entire catch is sorted and then sub-sampled as and where appropriate.

The Irish survey in the Irish Sea and Celtic Sea covers ICES Division VIIa and VIIg. The survey is conducted from 10 to 150 m depths during the fourth quarter (November-December) by the RV Celtic Voyager. This vessel is 32 m in length with gross tonnage of 340 t. The fishing gear used is a GOV 28.9/37.1 Trawl with Morgere Kite (0.85 by 0.85m). Mean vertical opening is 6 m and door spread 48 m. Morgere Polyvalent doors (Type AA4.5) are used and gear performance is monitored throughout the survey using the SCANMAR (RX400) net monitoring system (Headline height, Door spread).

Trials on the new 65m research vessel, the R.V. Celtic Explorer, are due to commence in late 2002. Therefore, from 2003 onwards all Irish Surveys will be conducted on this new vessel, starting around mid October through to late November.

The dataset collected includes assessment output relating to the years from 1905 to 2021 inclusive for annual estimates of the following variables for each stock: the annual recruitment estimate; the stock size (spawning stock biomass); landings (tonnes of fish brought to shore); catches (tonnes of fish caught at sea); fishing pressure (a fishing mortality rate); the target fishing mortality that will achieve maximum sustainable yield in the long term (Fmsy); upper and lower range estimates for Fmsy consistent with multi-annual plans and ICES advice; a threshold for spawning stock biomass (MSYB trigger), below which fishing mortality should be reduced below Fmsy, following the ICES advice rule, to avoid reduced reproductive capacity; a lower limit threshold for spawning stock biomass below which there is a high risk of reduced reproductive capacity (Blim). The stock assessment data for fish and shellfish stocks of UK interest is used to assess indicators of reproductive capacity (based on spawning stock biomass) and fishing pressure (based on fishing mortality). The applicable location for these data differ by stock, but are relevant to UK stock areas in the Celtic Sea / North Sea / wider North East Atlantic / Arctic region.

The purpose of the sand eel dredge survey is to collect sand eels buried in the seabed and compare catches (number and age composition) with the previous year's collections to assess the year class strength of sand eel in area 1r, 2r and 3r of the different areas adopted by ICES in 2016. Data from the dredge survey is the basis for calculating an index, which is used in the stock assessment for sand eel in the North Sea.

Delineation of the ICES Ecoregions was originally described in ICES Advice ACFM/ACE report(2004). In the present updated version, the delineation has been updated to account for additional policy objectives and reconciling of legislation (eg the MSFD and the EU water and habitats directives)

The differences are based on the four principles: 1. Within the EU accept the MSFD regional and sub-regional definitions. 2. Separate Icelandic Seas from those around Greenland. 3. Use Large Marine Ecosystem units to define the Arctic Ocean. 4. Use the accepted Norwegian regional management plans definitions of the Norwegian and Barents Seas.
