Explotación de la pesquería de arrastre de camarón durante el período 1991-1999 en el Golfo de Nicoya, Costa Rica / Exploitation of the shrimp trawl fishery in the period 1991-1999 at the Gulf of Nicoya, Costa Rica

In Costa Rica, the Gulf of Nicoya shrimp fishery originated in 1952 and represented one of the most important economic activities in the region. Nevertheless, overfishery reduced the captured volumes to levels that prevent this commercial activity. I analyzed official fishery statistics between 1991 and 1999. These species involved are: two species of white shrimp, (Litopenaeus occidentalis and L. stylirostris), the "titi" shrimp (Xiphopenaeus riveti), the brown shrimp (Farfantepenaeus californiensis), the "pinki" shrimp (F. brevirostris) and the "fidel" shrimp (Solenocera agassizi). All the species reached the Maximum Sustainable Yield in the decades of 1970 and 1980 and are now found at over-exploitation levels. I recommend that this shrimp trawl fishery be completely closed down.
