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) | [ RBS] | ||
---|---|---|---|
According to VMS-based estimates and ICES rectangle landings statistics, pots, pelagic trawls and nets (over-15m) and otter trawlers (whitefish, nephrops and other), netters, potters, pelagic trawlers and liners (under-15m vessels (indicated from ICES rectangle landings data)) operate within the RBS proposed MPA. The value of catches from the RBS area for over-15m vessels ( VMS data) cannot be disclosed as there were fewer than 5 vessels. The value of catches for under-15m vessels was £298,000 (indicated from ICES rectangle landings data) (annual average for 2007-2011, 2012 prices). Landings from the over-15m vessels are predominantly into Corunna, Spain (48% by value) and Ijmuiden, The Netherlands (39%), with small amounts into Lochinver (6%), Marin (4%) and Ullapool (2%). For the over-15m fleet, pots operate in particular around the edge of the seamount, while nets operate mainly over the top of the seamount, across the area of deep sea sponge aggregations and seamount communities. The deep sea sponge aggregations and seamount communities are in the central area of the proposed MPA, with differing feature extents under the different scenarios (lower: where deep sea sponge aggregations have been recorded; intermediate: across seamount down to 1000m depth; upper: across full extent of seamount). 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. A lower scenario which excludes mobile bottom-contact gear usebut does not exclude static gear use on deep sea sponge aggregations and seamount communities has also been included. VMS ping data indicate that three non- UK vessels were active in the RBS area in 2012: one from each of the Faroe Islands, Germany and Norway. The German vessel fishes with lines and therefore would be affected by management measures assessed under the intermediate and upper scenarios. No information on gear types used by the Norwegian of Faroese vessels was available. Information submitted by the French ministry indicated that 6 vessels fished in the proposed MPA area in 2008. They were all >40m and were predominantly demersal trawlers, targeting black scabbardfish and grenadiers, with catches worth €1.361 million (in 2008). The vessels originated from Boulogne-sur-Mer, Lorient and Saint-Malo ports, but had their home ports at Lochinver, Ullapool, Boulogne-sur-Mer and Saint Malo. 5% of their turnover was dependent on fishing in the proposed MPA area, and they accounted for 138 FTE jobs on board. Their fishing activity was mainly in the northern part of the proposed MPA area, and therefore may not be affected by management measures under the lower scenario. Provisional ScotMap data do not indicate any under-15m vessel activity in the RBS proposed MPA. The cost estimates for the under-15m sector may be overestimates, as the 'under-15m' length group in the ICES rectangle landings data may include cases where information on vessel length and/or administrative port is missing from landings returns. 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. |

* Value for non- VMS vessels only. VMS data represents less than 5 vessels and therefore cannot be disclosed. Total costs = Sum of one-off costs and recurring costs for the site summed over the 20 year period. Average annual costs = Total costs divided by the total number of years under analysis ( i.e. 20). Present value of total costs = Total costs discounted to their current value, using a discount rate of 3.5%. Total change in GVA (2014-2033) = The change in direct GVA in the sector for the site summed over the 20 year period. Average annual change to GVA = Total change in direct GVA in the sector for the site divided by the total number of years under analysis ( i.e. 20). Present value of total change in GVA (2014-2033) = Total change in direct GVA in the sector for the site discounted to current value, using a discount rate of 3.5%. Direct and Indirect reduction in Employment = The average (mean) reduction in direct employment in the sector plus the indirect reduction in employment on the sector's suppliers. |

Activity | Description |
Oil and Gas | There is currently no oil and gas activity within the RBS proposed MPA boundary, although licence blocks were offered in the 27 th licensing round that overlap with features under the all scenarios, but not accepted. With no awarded licence blocks or significant discoveries within the RBS proposed MPA boundary, it is unlikely that any future activity will occur and, therefore, no cost assessments have been made. |

Deep sea sponge aggregations | Provides representation for deep sea sponge aggregations in OSPAR Region V. | Provides one of at least three recommended examples to be protected in Scotland's seas. | Not currently understood for deep sea sponge aggregations. | Provides representation of an ecologically distinct type of deep sea sponge aggregation to those in the Faroe-Shetland Channel in OSPAR Region II and Hatton-Rockall Basin in OSPAR Region V. This type of deep sea sponge aggregation is only recorded in this location and not anywhere else in Scotland's seas. | Deep sea sponge aggregations are considered to be Threatened and/or Declining by the OSPAR Commission in OSPAR Region V so the MPA is expected to help increase resilience for the feature. |
Seamount communities | Provides representation for Seamount communities in OSPAR Region V. | Provides one of at least three recommended examples to be protected in Scotland's seas. | Not currently understood for seamount communities. | There are three seamounts recorded in Scotland's seas and these only occur within OSPAR Region V. MPA recommendations, considered alongside the existing MPA network, will mean the inclusion of all three seamounts in Scotland's seas in the resultant MPA network. | Seamount communities are considered to be Threatened and/or Declining by the OSPAR Commission in OSPAR Region V so the MPA is expected to help increase resilience for the feature. |
Seamounts | Provides representation for Seamounts in OSPAR Region V. | Provides one of at least two recommended examples to be protected in Scotland's seas. | The Rosemary Bank seamount is considered to be of wider functional significance to the health and diversity of Scotland's seas, e.g. enhanced biodiversity resulting from mixing caused by the interaction between the seamount and oceanic currents, increased productivity, and as feeding grounds for fish and marine mammals. | There are three seamounts recorded in Scotland's seas and these only occur within OSPAR Region V. MPA recommendations, considered alongside the existing MPA network, will mean the inclusion of all three seamounts in Scotland's seas in the resultant MPA network. | Seamounts are only distributed in OSPAR Region V in Scotland's seas. |
