Ten stocks (six demersal, four pelagic), six métiers (reef handline,
sediment longline and pelagic troll, each on a shallow and a deep ground)
and three segments (demersal and pelagic specialists, and a mixed
generalist fishing at 0.75 efficiency). The catchability matrix was
derived from the habitat landscape of cpueTargeting::simulate_logbook()
(seed 1). Daily costs are tuned so that the open-access equilibrium has
35/35/30% of days by segment and the weakest stock at 0.4 Bmsy (see
ms_tune()).
Details
Dentex (narrow reef habitat, high catchability relative to its growth rate) is the choke stock.
