ANALYSIS OF SHARK AND STRIPES CATCHES IN ARRAY FISHERIES OF TÁRCOLES, CENTRAL PACIFIC OF COSTA RICA

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 land...

description 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.

Se observaron 415 faenas de pesca (línea de fondo, trasmallo y línea rayera): 340 correspondieron a observaciones de descarga y 75 (18.1%) a observaciones a bordo. Durante las descargas se analizaron 3299 tiburones y rayas látigo: el tiburón mamón enano (Mustelus henlei) dominó en la captura total (63.7%), seguido por el tiburón mamón común (Mustelus lunulatus) (16.7%), el tiburón picudo común (Rhizoprionodon longurio) 6.9% y el tiburón martillo común (Sphyrna lewini) 6.1%. A su vez, la raya látigo (D. longa) y el tiburón picudo fucsia (Nasolamia velox) representaron un 3.5% y 2.6% de la captura total, respectivamente. En los 75 viajes a bordo se capturó un total de 6.458 peces, de los cuales solo el 4.4% (240 individuos) fueron tiburones y rayas látigo. M. henlei fue nuevamente la especie más abundante (50.4%), le siguieron R. longurio (21.7%), D. longa (13.8), N. velox (5.8%), S. lewini (5.8%), y por último, M. lunulatus (2.5%). Debido a la estacionalidad y abundancia de tiburones mamones en la zona de Herradura, se recomienda un cierre técnico en enero-febrero y setiembre-octubre, meses con las mayores capturas. También se recomienda la protección de la zona del Peñón, ya que es utilizada por la raya látigo y por los juveniles del tiburón martillo.  Analizaram-se as capturas de tubarões e raia ratão realizadas por pescadores artesanais de Tárcoles no Pacífico da Costa Rica, desde fevereiro de 2006 até fevereiro de 2007. Observaram-se 415 fainas de pesca (linha de fundo, tresmalho e linha de raia): 340 corresponderam a observações de descarga e 75 (18.1%) a observações a bordo. Durante as descargas analizaram-se 3.299 tubarões e raias ratão: o tubarão mamón enano (Mustelus henlei) dominou na captura total (63.7%), seguido pelo tubarão mamão común (Mustelus lunulatus) (16.7%), o cação-frango (Rhizoprionodon longurio) (6.9%) e o tubarão-martelo-recortado (Sphyrna lewini) (6.1%). Por sua vez, a raia ratão (D. longa) e o tubarão picudo fucsia (Nasolamia velox) representaram 3.5% e 2.6% da captura total, respectivamente. Nas 75 viagens a bordo capturou-se um total de 6.458 peixes, dos quais somente 4.4% (240 indivíduos) foram tubarões e raias ratão. M. henlei foi novamente a espécie mais abundante (50.4%), seguido por R. longurio (21.7%), D. longa (13.8), N. velox (5.8%), S. lewini (5.8%), e por último, M. lunulatus (2.5%). Devido à estacionalidade e abundância de tubarões mamones na zona de Herradura, recomenda-se um fechamento técnico em janeiro-fevereiro e setembro-outubro, meses com as maiores capturas. Também se recomenda a proteção da zona do Peñón, já que é utilizada pela raia ratão e pelos tubarão-martelo jovens. Universidad Nacional, Costa Rica.2011-07-21info:eu-repo/semantics/publishedVersionPeer-reviewed articleArtículo evaluado por paresArtigo revisto por paresartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlapplication/epub+ziphttps://www.revistas.una.ac.cr/index.php/revmar/article/view/24710.15359/revmar.1.8Revista Ciencias Marinas y Costeras; Vol. 1 (2009); 145-157Revista Ciencias Marinas y Costeras; Vol. 1 (2009); 145-157Revista Ciencias Marinas y Costeras; v. 1 (2009); 145-1571659-407X1659-455Xreponame:Portal de Revistas UNAinstname:Universidad Nacional de Costa Ricainstacron:UNAspahttps://www.revistas.una.ac.cr/index.php/revmar/article/view/247/203https://www.revistas.una.ac.cr/index.php/revmar/article/view/247/18574https://www.revistas.una.ac.cr/index.php/revmar/article/view/247/18575acceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2022-03-24T20:16:33Zoai:www.revistas.una.ac.cr:article/247Portal de revistashttp://revistas.una.ac.cr/Universidadhttp://www.una.ac.crhttps://revistas.una.ac.cr/index.php/index/oaiandrea.mora.campos@una.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2022-03-24T20:16:33Portal de Revistas UNA - Universidad Nacional de Costa Ricafalse
