Proposed protected features | |||||
Biodiversity Features Offshore subtidal sands and gravels, shelf banks and mounds, sandeels. Geodiversity Features None. Site Description The Turbot Bank MPA proposal lies in offshore waters to the east of Aberdeen. The MPA proposal encompasses the Turbot Bank shelf bank and mound large-scale feature, as well as relatively high densities of settled adult sandeels and appropriate sandeel habitat. Potential Alternative Designations At the request of Marine Scotland, JNCC have proposed science-based alternatives to the ocean quahog aggregations proposed protected feature (Norwegian Boundary Sediment Plain) and the shelf banks and mounds and offshore subtidal sands and gravels proposed protected features (Turbot Bank) of the Firth of Forth Banks Complex MPA proposal. However, it should be noted that regardless of the decision around these options, Turbot Bank is still recommended for the protection of sandeels in its own right. Cost impacts associated with human activities take into account the various alternative options (see Table 4), including the designation of all features and the designation of sandeels only. |

Human Activity Summaries
Human activities that would be impacted by designation of the site as an MPA
Table 4a. Commercial Fisheries (assuming zero displacement of fishing activity) | [ TBB] | ||
---|---|---|---|
According to VMS-based estimates and ICES rectangle landings statistics, whitefish trawls, dredges and pelagic trawls (over-15m) and pelagic trawls, pots, whitefish trawls, lines and dredges (under-15m vessels) operate within the TBB proposed MPA. The value of catches from the TBB area was £139,000 (over-15m vessels) and £9,100 (under-15m vessels, indicated from ICES rectangle landings data) (annual average for 2007-2011, 2012 prices). Landings from the over-15m vessels were predominantly into Peterhead (87% by value) and Fraserburgh (7%). For the over-15m fleet, there was sparse activity by dredgers and whitefish trawlers across the whole proposed MPA over areas of subtidal sands and gravels and sandeels. Non- UK VMS ping data indicate that 10 non- UK vessels were active in the TBB area in 2012: 8 from Denmark; 1 from France and 1 from the Netherlands. The majority fish with pelagic, static or unknown gear types and, therefore, would be unlikely to be affected by proposed management scenarios. Two Danish vessels fish with bottom trawl and, therefore, may be affected by the proposed management measures assessed under the intermediate and upper scenarios. Provisional ScotMap data do not indicate any under-15m vessel activity in the TBB proposed MPA. Management measures for the scenarios have been developed based on the sensitivity and vulnerability of the features to the pressures caused by different gear types and based on JNCC recommendations. Historically, the Turbot Bank possible MPA area was subject to industrial demersal trawling for sandeels. However, following the east coast of Scotland sandeel closure in 2000, the industrial sandeel fishery in Scottish waters has decreased dramatically. Although the westernmost edge of the TBB proposed MPA is the only section that overlaps with the closure area, it is likely that recent effort within the site does not reflect historic fishing patterns in the area. As such, no management measures have been associated with the designation of this feature. Unlike most other sectors, the potential cost of designation on commercial fisheries is a loss or displacement of current (and future) output, caused by restrictions on fishing activities. Any decrease in output will, all else being equal, reduce the Gross Value Added ( GVA) generated by the sector and have knock-on effects on the GVA generated by those industries that supply commercial fishing vessels. The costs estimates for this sector have therefore been estimated in terms of GVA. GVA estimates have been generated by applying fleet segment-specific 'GVA/total income' ratios to the value of landings affected. The GVA ratios have been calculated using data on total income and GVA from the Sea Fish Industry Authority Multi-year Fleet Economic Performance Dataset (published March 2013). Further details on the GVA ratios and the methodology for estimating GVA and employment impacts applied are presented in Appendix C7. It is important to note that all costs presented below assume that all affected landings are lost, that is, there is no displacement of fishing activity to alternative fishing grounds. In reality, some displacement is likely to occur and hence the cost, GVA and employment impacts presented in this table are likely to overestimate the costs. |

Offshore subtidal sands and gravels (option if FOF banks complex not designated) | Provides representation for a range of different types of offshore subtidal sand and gravel habitats on the continental shelf in OSPAR Region II. Turbot Bank is a relatively data-rich area for the habitat, but is not considered as data-rich as Firth of Forth Banks complex and so is being taken forward as a science-based alternative for representation of the feature in the Firth of Forth Banks Complex. | Provides one of at least two recommended examples to be protected on the continental shelf in OSPAR Region II in Scotland's seas. | Not currently understood for offshore subtidal sands and gravels. | Provides representation at the south-western extent of its range on the continental shelf in OSPAR Region II in Scotland's seas. | Offshore subtidal sands and gravels are widely recorded across offshore waters in Scotland's seas. |
Shelf banks and mounds | Provides representation for shelf bank and mound features that may be of wider functional significance to the health and diversity of Scotland's seas, although evidence is relatively weak compared to other shelf bank and mound areas ( e.g. Firth of Forth Banks Complex and Shiant East Bank). Therefore, the possible MPA is being considered as a science-based alternative to inclusion of the feature in the Firth of Forth Banks Complex possible MPA. | Provides representation for one of at least two recommended areas to be included in the MPA network for shelf banks and mounds considered to be of wider functional significance in Scotland's seas. | The Turbot Bank shelf bank and mound feature includes sediments of the appropriate type to harbour sandeels. These sandeels may be an important source of recruits to areas east and south of the Turbot Bank. | Provides representation at the south-western extent of its range in OSPAR Region II in Scotland's seas. | Shelf banks and mounds are fairly widely recorded across Scotland's seas. |
Sandeels | Provides representation for an area considered to be of importance to the life history of sandeels as a source of recruits to other sandeel grounds. | Provides one of multiple examples to be protected in Scotland's seas, based on advice received from Marine Scotland Science. | Sandeels from Turbot Bank may be an important source of recruits to areas east and south of the possible MPA. | Provides representation of an area importance to the life history of sandeels at the southern extent of their range in OSPAR Region II in Scotland's seas. | Sandeels are considered, in places, to be in decline in Scotland's seas. MPA-based management can help prevent further decline. |
