| Descripción: | From February 2006 to February 2007, we analyzed shark and rays captures by the artisanal fishermen from Tárcoles, in the Pacific of Costa Rica. We observed 415 fishing operations (bottom line, gillnet and ray line): 340 dock landing observations and 75 (18.1%) on board observations. During the landing observations, we analyzed 3299 sharks and rays: the brown smooth hound (Mustelus henlei) was the most common species (63.7%), followed by the common smooth hound (Mustelus lunulatus) (16.7%), the Pacific sharpnose shark (Rhizoprionodon longurio) (6.9%) and the scalloped hammerhead shark (Sphyrna lewini) (6.1%). The longtail stingray (Dasyatis longa) and the whitenose shark (Nasolamia velox) represented the 3.5% and 2.6% of the total catch, respectively. During 75 fishing trips, we analyzed 6.458 fish individuals, of them only 4.4% (240 individuals) were sharks and longtail stingrays. Among these, M. henlei was also the most abundant species (50.4%), followed by R. longurio (21.7%), D. longa (13.8%), N. velox (5.8%), S. lewini (5.8%), and M. lunulatus (2.5%). Considering the seasonality and abundance of smooth hound sharks in Herradura, we recommend a technical closure during the higher catch months (January-February and September-October). Also, we recommend protecting the Peñón, which is inhabited by adults of longtail stingray and juvenile scalloped hammerhead sharks. |
