Shrimp is the most valuable fishery
resource in Mexico, representing almost 40% of the total
production landed, with revenues of more
than US $ 132 million per year and with more than 30,000
direct and indirect jobs. Three penaeid
shrimp species account for >95% of the wild stock of the
Pacific coast. The blue and brown shrimp
of the southern Gulf of California are exploited to their
maximum capacity, while white shrimp is
considered over-exploited. The stocks were evaluated with a
simulation model. In current fishing the
age of first catch is overexploiting juveniles, therefore,
increasing the age of first catch from 4
to 5 months is one of the recommendations. Then two fishing
scenarios were tested, the maximum
sustainable yield (MSY) and the MSY/fisher. On the impossibility
to address particular policies for each
species, it was concluded that for the MSY scenario, 1000
permits per season would fulfill most of
requirements, in the second case (MSY/Fisher), by reducing
the current number of boats to 530, would
achieve the required goal.
