The small-scale tuna longline fishery operating on the coast of Nayarit started recently in 2013. We provide the first detailed report on some biological parameters for the yellowfin tuna (YFT) in Nayarit (Mexico). We sampled 584 YFT, representing a catch of 25.5 t. We fit the length-weight relationship, used the t-test to determine the type of growth, and estimated the selectivity curve. The total length data varied from 73.0 to 228.0 cm, with a mean of 153.0 ± 23.5 cm (mean ± SD). Weight ranged from 5.8 to 128.0 kg, with a mean of 43.7 ± 19.4 kg. Length-weight fitting results and the t-test suggested negative allometric growth. Selectivity fitting results suggested that selectivity follows an asymptotic pattern. Our results represent the first step into gathering information to establish research and monitoring programs for the YFT on the Pacific coast of Mexico. The information provided in this study could help develop proper regulations to assure a well-managed fishery and the sustainable exploitation of YFT in Nayarit.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen. La pesquería de pequeña escala de atún que opera con palangre en la costa de Nayarit comenzó recientemente en 2013. Ofrecemos la primera información detallada sobre algunos parámetros biológicos del atún aleta amarrilla (AAA) en Nayarit (México). Tomamos 584 muestras de AAA (captura de 25.5 t). Ajustamos la relación longitud-peso, utilizamos la prueba de t para determinar el tipo de crecimiento y estimamos la curva de selectividad. La longitud total varió de 73.0 a 228.0 cm, con una media de 153.0 ± 23.5 cm (media ± desviación estándar). El peso varió de 5.8 a 128.0 kg, con una media de 43.7 ± 19.4 kg. Los resultados del ajuste de longitud-peso y la prueba de t sugirieron que el crecimiento es alométrico negativo. Los resultados del ajuste de la selectividad sugirieron que la selectividad sigue un patrón asintótico. Nuestros resultados representan el primer paso en la recopilación de información para establecer programas de investigación y monitoreo de AAA en el océano Pacífico frente a México. La información proporcionada en este estudio podría ayudar a desarrollar las regulaciones para asegurar una pesquería bien administrada y la explotación sostenible del AAA en Nayarit.]]></p></abstract>
