Blue shrimp (Litopenaeus stylirostris) catch quotas as a management tool in the Upper Gulf of California

Within the buffer zone of the Upper Gulf of California and Colorado River Delta Biosphere Reserve (established June 1993), the shrimp fishery is managed as a common and rational use resource, trying to minize the impact of fishing effort on both the resource and ecosystem. An analysis was thus made...

An analysis was thus made of potential catch quotas of Litopenaeus stylirostris using a dynamic model to estimate expected shrimp yield and future biomass that includes fishing season as a factor and catch per unit effort (CPUE) as abundance index. The CPUE of L. stylirostris declined in the 1990/91 season and tended to recover in 1995/96. The parameters of the biomass dynamic model were K = 21,323 t (±700 t, P < 0.05) and r = 1.18 (±0.1, P < 0.05). The estimated catchability was 0.00032 with a standard deviation of 0.25.
