| description |
Green spiny lobster Panulirus gracilis is an economical resource of high importance for fishermen populations in the continental coast of Ecuador. Traditionally, this specie is captured using gillnets and semiautonomous diving system (hookah). With the objective to analyze some biological aspects about this fishery in Manabí, we examined lengths of capture (carapace length: CL and abdominal length: AL), sex ratio and reproductive aspects in females between June and September 2010. A total of 415 females and 288 males were captured with gillnets in El Mangle-Puerto Cayo (Central coast, depth: 3-6m), and by diving in Puerto López-Salango (South coast, depth: 7-12m). Sex ratio from males to females was 0.72:1 for gillnets, and 0.63:1 for diving. Lobsters captured by diving were larger (84.1±3.3mm CL) than lobsters captured by gillnets (73.4±2.9mm CL). Percentage of ovigerous females captured by diving was higher than females captured by gillnets. There was a pattern between lengths by sex (relation AL vs. CL); females were larger than males at same CL. Differences found between lengths and the occurrence of ovigerous females could be related with depth where capture methods are used. A total of 98% of landed lobsters were smaller than legal captured length and we recommend the establishment of a monitoring evaluation program during the fishing season, and a ban, in order to evaluate the natural fluctuation in length and reproductive stages of green spiny lobster in the coasts of Manabí. |

Esta especie es capturada tradicionalmente mediante redes y buceo semiautónomo (hookah). Para analizar algunos aspectos biológicos de la pesquería en la provincia de Manabí, se examinó la talla de captura (longitud cefalotorácica: LC y abdominal: LA), proporción sexual y aspectos reproductivos en hembras (n=415) de 703 especímenes entre junio y septiembre 2010: con red en El Mangle-Puerto Cayo (costa central, profundidad: 3-6m), y mediante buceo en Puerto López-Salango (costa centro-sur, profundidad: 7-12m). La proporción sexual: machos a hembras fue 0.72:1 para captura con red y 0.63:1 para buceo. Las langostas capturadas con buceo fueron más grandes (84.1±3.3mm LC) que las capturadas con red (73.4±2.9mm LC). La proporción de hembras ovígeras capturadas con buceo fue mayor que en las capturas con red. La diferencia entre talla y ocurrencia de hembras ovígeras podría relacionarse con la profundidad a la que los métodos de captura fueron utilizados. El 98% de las langostas analizadas estuvieron por debajo de la talla legal. Se propone el establecimiento de un programa de evaluación continua del recurso durante la temporada de pesca y veda para conocer la fluctuación natural del tamaño y época reproductiva de la langosta verde en Manabí.Universidad de Costa Rica2013-09-01info:eu-repo/semantics/publishedVersionartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdfhttps://revistas.ucr.ac.cr/index.php/rbt/article/view/1192410.15517/rbt.v61i3.11924Revista de Biología Tropical; Vol. 61 No. 3 (2013): Volume 61 – Regular number 3 – September 2013; 1189–1199Revista de Biología Tropical; Vol. 61 Núm. 3 (2013): Volumen 61 – Número regular 3 – Setiembre 2013; 1189–1199Revista Biología Tropical; Vol. 61 N.º 3 (2013): Volumen 61 – Número regular 3 – Setiembre 2013; 1189–11992215-20750034-774410.15517/rbt.v61i3reponame:Portal de Revistas UCRinstname:Universidad de Costa Ricainstacron:UCRspahttps://revistas.ucr.ac.cr/index.php/rbt/article/view/11924/11229Derechos de autor 2013 Revista de Biología Tropicalacceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2022-10-13T15:40:58Zoai:portal.ucr.ac.cr:article/11924Portal de revistashttps://revistas.ucr.ac.cr/Universidadhttp://www.ucr.ac.crhttps://revistas.ucr.ac.cr/index.php/index/oaijorge.polanco@ucr.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2025-08-13T10:15:36.862Portal de Revistas UCR - Universidad de Costa Ricafalse |
