Sustainability of the Fishery

Until 2007 management of exploitation levels of the fishery was controlled by restriction on fishing capacity rather than through quota. The fishery was limited to a 2-vessel fishery and maximum catch was restricted by the fishing capacity of these two vessels.

Since the introduction of an ITQ system in 2007, fishing is limited to quota that is determined each year by the outcome of a stock assessment process. Since 2013 the assessments have used an Age-Structured Production model (ASPM) in CASAL modelling software to establish the maximum sustainable yield and the ration of current stock biomass to unfished spawning stock biomass. The model includes the ability to forecast changes in the stock biomass depending on harvesting levels and other variables. Lastly, a series of Harvest Control rules to define the parameters under which quota is allocated on the basis of the stock assessment outcomes ensures the transparency and consistency of quota allocation.
