Abstract = {{Wehave used in this study a spatially explicit bioeconomic modelling
   framework to evaluate management strategies, building in both datarich
   and data-limited harvest control rules (HCRs), for a mix of deepwater
   fleets and species, on which information is variable. The main focus was
   on blue ling (Molva dypterygia). For that species, both data-rich and
   data-limited HCRs were tested, while catch per unit effort (CPUE) was
   used either to tune stock assessments, or to directly trigger management
   action. There were only limited differences between the performances of
   both HCRs when blue ling biomass was initialized at the current level,
   but blue ling recovered more quickly with the data-rich HCR when its
   initial biomass was severely depleted. Both types of HCR lead, on
   average, to a long-term recovery of both blue ling and saithe
   (Pollachius virens) stocks, and some increase in overall profit.
   However, that improvement is not sufficient to guarantee sustainable
   exploitation with a high probability. Blue ling CPUE did not always
   adequately reflect trends in biomass, which mainly resulted from fleet
   dynamics, possibly in combination with density-dependence. The stock
   dynamics of roundnose grenadier (Coryphaenoides rupestris), black
   scabbardfish (Aphanopus carbo) and deepwater sharks (Centrophorus
   squamosus and Centroscymnus coelolepis) were little affected by the type
   of HCR chosen to manage blue ling.}},
