ABSTRACT
Haddock is a medium-sized gadoid species that can be found across a wide area of the northern Atlantic. In the North Sea, haddock are found mostly in the central and northern areas, and are very seldom encountered south of a line joining the north-east of England and southern Norway through the Dogger Bank. In the evaluation process, 50 simulation-based evaluations of the management procedure were run each for 25 years into the future, and for a series of scenarios with different Ftarget values. The time period for the simulations was chosen to ensure that the conclusions were not wholly dependent on the particular starting values: the oldest age in the historical assessment was 10, so at least 10 simulation years would be required to ensure that the influence of the starting year was minimised. The North Sea haddock management strategy evaluation (MSE) analysis consisted of three concentric loops: the Ftarget loop, which considers different values of Ftarget.
