Mean size at sexual maturity of female Cynoscion reticulatus along the Pacific coast off Mexico

Drums and croakers (Sciaenidae) are important to the species composition of coastal catches in the Gulf of California, Mexico. Among these species, the striped corvina (Cynoscion reticulatus) stands out because of its high fishery potential, high demand, and increased market value. The striped croak...

description Drums and croakers (Sciaenidae) are important to the species composition of coastal catches in the Gulf of California, Mexico. Among these species, the striped corvina (Cynoscion reticulatus) stands out because of its high fishery potential, high demand, and increased market value. The striped croaker has been under constant fishing pressure over the past 20 years. Still, there needs to be current biological information or reference points to allow the establishment of management measures for fisheries. The objective of the present study was to estimate the mean standard length at sexual maturity (SL50) of females using various models and to suggest a minimum catch size (MCS) for C. reticulatus off the southern coast of Sinaloa. Monthly samplings of coastal fishery landings were done from December 2020 to December 2021 on the south coast of Sinaloa. The SL50 was evaluated based on 3 candidate models (Gompertz, Lysack, and White) through a binomial approach. Confidence intervals for SL50 were estimated using likelihood profiles and contours, and Akaike’s information criterion (AIC) was used to select the best model. A total of 284 individuals were examined, of which 131 were used in calculations. White’s model was the most adequate; however, based on AIC weights, all 3 models performed similarly, and SL50 (24.48 cm; C.I. 95% 12.9–70 36.0 cm) was estimated as their average. As a management measure, we propose a precautionary MCS of 36 cm SL for C. reticulatus off southern Sinaloa.

Los tambores y roncadores (Sciaenidae) son parte importante de la composición específica de las capturas costeras en el Golfo de California, México. Dentro de este grupo de especies, la curvina rayada (Cynoscion reticulatus) destaca por su alto potencial pesquero, gran demanda y debido a que ha incrementado su valor de mercado. La curvina rayada ha estado bajo constante presión pesquera durante los últimos 20 años. Sin embargo, se necesita contar con información biológica actual o puntos de referencia que permitan establecer medidas de manejo pesquero. Por tanto, el objetivo del presente estudio fue estimar la longitud estándar media de madurez sexual (LE50) utilizando varios modelos para sugerir una talla mínima de captura (TMC) de C. reticulatus en la costa sur de Sinaloa. Para esto, se realizaron muestreos mensuales en las descargas de la flota costera desde diciembre de 2020 hasta diciembre de 2021 en la costa sur de Sinaloa. La LE50 se evaluó con base en 3 modelos candidatos (Gompertz, Lysack y White) a través de un enfoque binomial. Los intervalos de confianza para la LE50 se estimaron utilizando perfiles y contornos de verosimilitud, y se utilizó el criterio de información de Akaike (CIA) para seleccionar el mejor modelo. Se examinaron un total de 284 individuos, de los cuales 131 se utilizaron en el análisis. El modelo de White fue el más adecuado; sin embargo, con base en los pesos de CIA, los 3 modelos mostraron un rendimiento similar, por lo que la LE50 (24.48 cm; IC 95% 12.9-​36.0 cm) se estimó como el promedio de estos. Por último, como medida de manejo, proponemos una TMC bajo un enfoque precautorio de 36 cm LE para C. reticulatus en la costa sur de Sinaloa.
