   2010. Stochastic bioeconomic modelling of alternative management
   measures for anchovy in the Mediterranean Sea. - ICES Journal of Marine
   Science, 67: 1291-1300.
   The purse-seine fishery for anchovy in the Aegean Sea consists of two
   main fleet segments (12-24 and 24-40 m vessels); this paper investigates
   economically and biologically preferable effort and capacity scenarios
   for the fishery. Attention is paid to a bioeconomic analysis of fleets
   composed of segments with varying levels of efficiency ( in terms of
   catch rate) and costs ( fixed and variable) and the role this might play
   in optimal effort allocation at a fleet level. An age-structured
   stochastic bioeconomic operating model for Aegean anchovy (Engraulis
   encrasicolus) is constructed. It attempts to account robustly for the
   multiple uncertainties in the system, including (i) the effort-fishing
   mortality relationship, (ii) the selectivity, and (iii) the
   stock-recruit dynamics of the population. A method is proposed for
   determining the economically optimal level of long-term effort in a
   fishery such as this, with similar characteristics in terms of stock
   dynamics, fishery, and markets. Lower values of effort and capacity are
   predicted to yield greater future profit when viewing the fleet in its
   entirety, but even lower values may be advisable to maintain the
   long-term biological integrity of the stock. The results may prove
   useful in balancing the productivity of the stock with the harvesting
   capacity of the fleet, while managing to ensure the long-term
   profitability of the fleet along with the sustainability of the
   resource.}},
