Investigation and Assessment of the Exploitation Strategies of the Shrimp Fishery of the Gulf of California

September 2, 2020 BIOLOGY 0

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.
