En el presente capitulo se reporta y describe la estadística descriptiva e índices de abundancia nominales de las principales especies capturadas por la flota de tiburón de mediana altura del Pacífico mexicano
Information about reproductive parameters, such as age and length at which half the population matures (A50 and L50) of the pelagic thresher (Alopias pelagicus) in the Mexican Pacific, is scarce. To fill this knowledge void, we used maturity data collected from 2015 females and 2030 males captured by pelagic longliners in the Mexican Pacific during...
The pelagic thresher shark (Alopias pelagicus) is considered overexploited; however, information about its biology in the Eastern Pacific is scarce, particularly age estimation and growth modeling. Age was estimated by counting growth bands in the cervical vertebrae. Specimens, ranging in size from 85.00 to 174.90 cm precaudal length (PCL), were co...
Se presenta el análisis de la información disponible sobre la pesquería de tiburón y pez vela en el Pacífico de Costa Rica. El objetivo principal fue evaluar el impacto económico y biológico de estas pesquerías, así como proporcionar información sobre la dinámica espaciotemporal de la flota. Se analizaron los datos de desembarques de tiburón y pez...
Sharks in Mexico have economic, fishing, and social importance; however, there are
no complete assessments of their populations, mainly due to scarce and inadequate catch and effort data. Nevertheless, through size frequency analysis, it is possible to obtain preliminary fishing indicators to know the status of an exploited population. This study a...
Knowledge of life history and fish reproduction is essential to understand the population dynamics of exploited shark populations. We provide information regarding the length, weight, and sex ratio of Carcharhinus longimanus (oceanic whitetip shark), Galeocerdo cuvier (tiger sharks) and Alopias superciliosus (bigeye thresher sharks) from longline b...
The occurrence of the Filetail catshark Parmaturus xaniurus is rare in the Gulf of California (GC), and its population structure is unknown. We reported its occurrence as bycatch of the Pacific hake fishery in the northern GC. We examined 22 mature females (412-620 mm total length) caught at 263.0-360.2 m depth.
En el presente informe se resume la información obtenida en el reporte
“Análisis de la información de la pesquería de grandes pelágicos de interés
comercial capturados y desembarcados por las flotas que operan dentro y
fuera de la ZEE del Pacífico de Costa Rica”. En términos generales, se muestran
las zonas de operación y desembarques de la flota p...
The Smooth Butterfly ray Gymnura micrura is caught directly and indirectly in the Gulf of Mexico. In order to know their life history, the age and growth parameters were estimated in 96 females captured from October 2015 to September 2016. The age was assigned following conventional protocols comparing the counts between readers and assuming an ann...
Most shark records are reported using different types of measurements; thus, length-to-length conversion parameters are needed to standardize and compare the available data as a function of different size measures. Shark biological information collected in the Mexican Pacific Northwest between 2006 and 2019 was used to estimate total fork length/pr...
La raya mariposa Gymnura micrura es capturada directa e indirectamente en el golfo de México. Para conocer su historia de vida, se determinó la edad y se estimaron los parámetros de crecimiento en 96 hembras capturadas durante octubre 2015 a septiembre 2016. La edad se asignó siguiendo protocolos convencionales comparando los conteos entre lectores...
Life-history studies of species discarded in fisheries are a low priority, particularly those of age and growth estimation. Consequently, almost everything is unknown about such species despite their having been caught as bycatch over the long term. In this study, age estimates were obtained by using the vertebrae of round stingrays (Urobatis halle...
El presente capítulo tiene como objetivo evaluar de manera preliminar el estado de las poblaciones de las especies de tiburones que han sido incorporadas en años recientes al
Apéndice ii de la Convención sobre el Comercio Internacional de Especies Amenazadas de Flora y Fauna (CITES) que se aprovechan en aguas de México, a partir del método para dat...
En aguas mexicanas del Pacífico, Golfo de México y Caribe mexicano se han documentado alrededor de 111 especies de tiburones (Del Moral et al., 2015) de las cuales cerca de 40 son de importancia comercial y que son aprovechadas en las aguas costeras y de mar abierto de ambos litorales de México. Este grupo de peces cartilaginosos representa un impo...
The aim of this study was to use a Bayesian approach to estimate age and growth parameters for the golden cownose ray (Rhinoptera steindachneri) in the southern Gulf of California in Mexico. Age estimates were obtained through analysis of vertebrae of 249 individuals. The von Bertalanffy growth function (VBGF) and Gompertz growth model (GM) were fi...
Rhinoptera steindachneri is one of the species with the greatest presence in the landings of batoid in the Gulf of California, however, it has biological characteristics that make it susceptible to overfishing and although it does not present a directed fishery, it is imperative to carry out studies to evaluate its resilience under natural conditio...
Nerocila acuminata (Crustacea: Isopoda: Cymothoidae), ectoparasite of speckled guitarfish Pseudobatos glaucostigma (Elasmobranchii) from southeastern Gulf of California, Mexico The ectoparasite isopod, Nerocila acuminata attaches to the skin of a variety of marine fish species; however , there is not much literature that mentions it infesting elasm...
Given the high degree of uncertainty on key parameters associated with age and growth of shortfin mako and other pelagic sharks, the Shark Working Group (SHARKWG) of the International Scientific Committee for Tuna and Tuna-like Species in the North Pacific Ocean (ISC), have highlighted the need to take action to standardize protocols for sampling c...
