520 _ _ a| Aunque existen estudios sobre las pesquerías de batoideos en aguas Mexicanas, falta información sobre la influencia de factores sobre las operaciones pesqueras y las tasas de captura. Para evaluar el efecto de algunos factores en la pesquería dirigida sobre la raya pinta Aetobatus narinari en el Sur del Golfo de México, se realizaron registros diarios de las operaciones pesqueras de cuatro embarcaciones menores en dos localidades (Campeche y Seybaplaya), de enero a julio 2009 (temporada de pesca completa). Fueron registradas 896 rayas en 280 viajes de pesca. Se utilizó el Modelo General Lineal para evaluar la influencia de los factores en las operaciones de pesca y las tasas de captura. La operación pesquera fue predicha por el ciclo lunar (frente a Campeche) y la velocidad del viento (frente a Seybaplaya). Las tasas de captura frente a Seybaplaya fueron predichas por el factor embarcación, la temporada de frentes fríos y la temperatura superficial del mar. Este estudio demuestra que tanto los factores ambientales como las diferencias en la asignación del esfuerzo pesquero entre embarcaciones, influyen en las tasas de captura, por lo que deben ser considerados en estudios futuros que comparen tasas de captura entre estaciones del año y regiones.
520 1 _ a| Aetobatus narinari represents a fisheries target in Southern Gulf of Mexico, and it is currently considered a Near Threatened species by the IUCN red list. The information available of this batoid fish includes some biological and fishery aspects; nevertheless, little is known about the factors influencing on fishing operations and catches. In order to evaluate the effect of environmental factors and the fishing effort allocation by vessels on the target fishery of A. narinari in this area, a daily basis sampling was carried out on four small-scale vessels, from January to July 2009 (the entire fishing season), in two fishing localities (Campeche and Seybaplaya). A total of 896 rays were recorded from 280 fishing trips. A General Linear Model was used to predict the factors effect on the probability that fishing operations occurred, and on the probability for captures of at least one or three or five rays per vessel-trip. The probability that fishing operations occurred off Campeche was predicted by the lunar cycle, with the highest probability in the new moon period (66%) and a probability smaller than 35% for the other periods. The probability that fishing operations occurred off Seybaplaya was predicted by wind velocity, with higher probabilities at low wind velocity than at high wind velocity, and a 50% probability of fishing operations at 12-15km/h. Catch rates off Seybaplaya were predicted by the vessel´s factor (the effect of fishing effort allocation), the North wind season and sea surface temperature.
520 1 _ a| The probability for capture at least five rays per vessel-trip was predicted by the sea surface temperature and the North wind season. At 23°C the catch probability was of 49% and the probability gradually diminished to 4% at 28°C, and during the North wind season the catch probability was higher (40%) than out of that season (7%). This study shows that some environmental factors and fishermen perceptions and experience (fishing effort allocation) influence on the catch rate of A. narinari, and that these factors must be considered in future studies on elasmobranch fisheries, mainly when comparisons between catch rates among seasons or regions are analyzed.
