11 THE BASELINE: OUTER HEBRIDES ( IFG 3)

11.1 Introduction to Area

The area covered by the OH IFG is an area in the Minches and Sea of the Hebrides bordering with the North West IFG in the North and with Mull and the Small Isles IFG in the South plus the area to the West of the Hebrides following the 6 NM IFG boundary and a 6 NM radius around St Kilda, Flannan Isles, North Rona and Sula Sgeir (see map below).

Figure 11.1. Outer Hebrides IFG Area

Figure 11.1. Outer Hebrides IFG Area

The population is around 26,500 and accounts for only 0.5% of the Scottish population. Marine recreational and general public values will be correspondingly smaller than in the more populated IFGs.

The Stornoway Fishery District administers the following ports: Barra, Benbecula, Bernera, (Lewis), Berneray (N Uist), Grimsay, Lochs, North Harris North Uist, Portnaguran, Ness, Scalpay, South Harris, South Uist, Eriskay, Stornoway.

Pelagic and white fish fisheries used to be important but presently very little effort is directed at these fisheries. In common with the South West and North West IFG areas, fishing for shellfish is now the primary activity and accounts for virtually all landings by value into Western Isles ports. In the Minches, the main species targeted are Nephrops, scallops, crab and lobster. The inshore sea areas to the west and north provide the main grounds for lobster, brown crab and crawfish.

The majority of the locally based inshore fleet is now under 10 m in length. Over the past decade, trawling effort has decreased whilst the creeling sector has been increasing to the extent that creel caught Nephrops account for over a third of all shellfish landings. Nomadic trawlers targeting Nephrops tend to land their catch in mainland ports.

In descending order of landings values, Nephrops, lobster, scallops, brown crab, velvet crab are the key shellfish species.

The main processors are; Scottish Seafoods Ltd in Lewis and Harris employing around 50 people processing for the UK scampi market, Kallin Shellfish Ltd, in the Uists, employing 14 people processing scallops and brown crab, and Barratlantic Ltd, on Barra employing around 40 processing Nephrops scallops and white fish species.

There are a number of buyers specialising in live shellfish and offering live storage facilities. On Barra, Aurora Shellfish and Sandray Shellfish buy live shellfish buyers for shipping to the continental market. In the Uists, the live shell fish buyers are Kilbride Shellfish, North Uist Fish Marketing, W Stewart Live Fish, W MacDonald Shellfish, Live Langoustine, Sutherland Game and Scot West. In Lewis and Harris, the buyers are Hebridean Marine, Sandray Shellfish, Keltic Seafare, Sutherland Game and Scot West.

The fleet has a very similar profile to the North West IFG with a preponderance of small creel vessels.

Virtually all landings are by Scottish vessels. Like the South West area, the Outer Hebrides area would appear to support almost exclusively shellfish fisheries. Whist the North West has some similarities, it lands a significant value of demersal fish caught by Scottish and non-Scottish vessels but caught outside the IFG area

11.5 MPAs, Legislation & Regulations specific to the IFG Area

There are two MPAs within the IFG area. In the table below we have estimated the area of both the 0-1 NM and 0-3 NM that would be covered by an MPA site.

MPA Area ( KM) within 0-1 NM Area ( KM) within 0-3 NM

Monach Isles 0.1 63.7
Total 438.8

Specific Legislation and Regulations:

Area Prohibition
Lochmaddy to Stuley Island to Barra Head and Gurney Point Mobile gear prohibitions 1 March – 31 October Scallop dredging permitted 1 March – 31 April and 24 August – 31 October Sandeel fishing permitted 1 March - 31 October in Stuley Island – Barra Head area
Sound of Harris Mobile gear prohibitions 1 March – 30 September, scallop dredging permitted during that period
Broad Bay All year prohibition on mobile gear to protect juvenile plaice
Loch Roag All year prohibition on mobile gear
Flannan Isles Prohibition of creel fishing 1 November – 31 March
West of Barra – Scarp Island Prohibition of creel fishing 1 November – 31 March
Bragar to Dell - West of Lewis Prohibition of creel fishing 1 July – 30 September

An area off Harris has been identified as grounds suitable for trawlers and a local agreement on access has been reached between both static and mobile gear sectors. Trawlers must give prior notification to static gear operators before they intend to commence fishing in the area, so that static gear can be shifted to allow access for the trawlers. Trawl activity in the area is usually on a seasonal basis.

An area between Chicken Head and Cellar Head has a high concentration of brown crab creels from 1 November until 31 March. Scallop dredgers also dredge in the area on a limited basis during this period and an agreed code has been developed to accommodate

The next section reports the catch estimates derived through our manipulation of VMS and Scotmap data

From the above tables, it is estimated that the value of landings taken from the IFG water in 2011 (i.e. 0-6 NM) by Scottish vessels is £10.5 m of which 37.9% is caught within 1 NM and 74% within 0-3 nm. This is similar to the proportions estimated for the South West and North West

A total of £3.99 m was caught in the 0-1 NM zone, the comparable figure for the 1-3 NM zone was £3.76m

Within both the 0-1 and 0-3 nm, static gear take a larger share of the catch than mobile gears and 15 m and under vessels catch significantly more than the over 15 m vessels.
