Estimation of maximum sustainable yield of the shark resource from Mexico

Estimation of maximum sustainable yield of the shark resource from Mexico

In Mexico, shark catch ranks 10th place out of the 22 most representative fisheries in the country, with an estimated annual average number of 29 772 T and an economic income of approximately MXN 437 million. The maximum sustainable yield (MSY), which means the maximum catch that can be obtained wit...

description In Mexico, shark catch ranks 10th place out of the 22 most representative fisheries in the country, with an estimated annual average number of 29 772 T and an economic income of approximately MXN 437 million. The maximum sustainable yield (MSY), which means the maximum catch that can be obtained without the depletion of the fishing resource at any given time is one of the main points of reference in the evaluation of fisheries. In this study, the MSY of sharks in Mexico was estimated for 26 coastal areas (Mexico, Pacific ocean, gulf of Mexico, 6 regions of the NOM-029-PESC-2006 and 17 coastal States). Catch time series (CTS) were used in tons per year of reported catch (Rc) and total catch (Tc) (reported catch + non-reported catch) over the 1976 to 2014 period. In addition, empirical models that relate the maximum catch of the STM to the MSY were applied. There were no significant differences between the models applied. Based on the estimated Tc and MSY (T x 103) there is an over-exploitation of sharks in Mexico (Tc = 51 417, MSY = 29 040), in the Pacific ocean (Tc = 38 654, MSY = 20 840) and in the gulf of Mexico (Tc = 15 737, MSY = 14 540); in Regions 2 (gulf of California) (Tc = 22 664, MSY = 14 330) and 5 (coastal line of Tamaulipas, Veracruz and Tabasco) (Tc = 9 202, MSY = 8 510) and on thecoast of the States of Baja California (Tc = 5 781, MSY = 4 880) and Baja California Sur (Tc = 5 950, MSY = 5 510). It is recommended to urgently address the problem of using this fishery resource in the Mexican Republic.

En México, la captura del recurso pesquero tiburón-cazón (RTC) ocupa el décimo lugar delas 22 pesquerías más representativas del país, con un volumen anual promedio estimado en 29 772 T, y una derrama económica de 437 millones de pesos mexicanos. La captura máxima que se puede obtener sin agotar el recurso en ningún plazo, se denomina rendimiento máximo sostenible (RMS), y es uno de los principales puntos de referencia en la evaluación de pesquerías. El objetivo del presente estudio fue estimar el rendimiento máximo sostenible del recurso pesquero tiburón-cazón, agrupándolo en 26 regiones (México, océano Pacífico, golfo de México, 6 regiones de la NOM-029-PESC-2006 y 17 estados costeros). Se utilizaron series de tiempo de captura (STC), en toneladas por año de captura reportada (Cr) y captura total (Ct) (captura reportada + captura no reportada) del periodo de 1976 a 2014, y se aplicaron modelos empíricos que relacionan la captura máxima de la STC con el RMS. No hubo diferencias significativas entre los modelos. Con base en la Ct y el RMS estimados (T x 103) se evidencia una sobreexplotación del RTC en México (Ct = 51 417, RMS = 29 040), en el océano Pacífico (Ct = 38 654, RMS = 20 840) y en el golfo de México (Ct = 15 737, RMS = 14 540); en la Región 2 (golfo de California) (Ct = 22 664, RMS = 14 330) y Región 5 (línea costera de Tamaulipas, Veracruz y Tabasco) (Ct = 9 202, RMS = 8 510), y en la costa de los estados de Baja California (Ct = 5 781, RMS = 4 880) y Baja California Sur (Ct = 5 950, RMS = 5 510). Es necesario atender de forma urgente la problemática del aprovechamiento de este recurso pesquero en la república mexicana.
