Table 14.5 Definitions of Sensitivity of Commercial Fisheries Receptors Sensitivity
Definition High
Low spatial adaptability due to limited operational range and ability to deploy only one gear type.
Limited spatial tolerance due to dependence upon a single fishing ground.
Low recoverability due to inability to mitigate loss of fishing area by operating in alternative areas.
Medium
Some spatial adaptability due to extent of operational range and / or ability to deploy an alternative gear type.
Moderate spatial tolerance due to dependence upon a limited number of fishing grounds.
Limited recoverability with some ability to mitigate loss of fishing area by operating in alternative areas.
Low
High spatial adaptability due to extensive operational range and / or ability to deploy a number of gear types.
High spatial tolerance due to ability to fish a number of fishing grounds.
High recoverability due to ability to mitigate loss of fishing area by operating in range of alternative areas of the North Sea.
Negligible
Category of fishing receptor with an extensive operational range and very high method versatility.
Vessels are able to exploit a large number of fisheries.
14.4.3.4 Magnitude The magnitude of an effect is considered for each predicted impact on an individual
33.
fishery basis and is defined spatially, temporally and proportionally taking account of the likelihood of occurrence. The magnitude of the potential effect on a given receptor for different proposed East Anglia THREE project phases is primarily a function of dependence on the area under consideration. The criteria used to define magnitude of a potential impact on commercial fisheries are provided in Table 14.6.
34. With respect to duration of potential impacts, those associated with construction are
considered to be short term occurring over a maximum of 2.5 years. Impacts associated with operation are long term, occurring over the 25 year operational lifetime of the proposed East Anglia THREE project. Due to the highly seasonal nature of certain fisheries, it is not possible to standardise the definition of duration of effects across the receptor groups as the timing of specific seasonal fisheries varies considerably.
