          Abstract

          Abstract White grunt (Haemulon plumierii) has gained relevance as an alternative resource to fisheries off the northern coast of the Yucatán Peninsula, however, knowledge of its biology in the region is scarce. Thus, in order to explore the reproductive biology of H. plumierii, a total of 355 specimens were caught with a hand line and bait, from September 2015 to November 2016 to conduct histological analysis of the gonads. The sample was represented by 233 males and 122 females, differing from the 1:1 sex ratio (1 female per 2.1 males). The reproductive season occurred from February to August with a maximum peak in May. The 50% maturity size (L50) was estimated at 15.15 and 15.22 cm TL for males and females, respectively. The batch fecundity ranged from 9,363 to 42,371 eggs per batch, with an average of 26,558 eggs. Several reproductive biology features were observed in H. plumierii, such as spring spawning seasonality, length at sexual maturity, asynchronous oocyte development with an indeterminate fecundity, and batch spawning. This kind of information can guide proposals for further sustainable fishery management measures that may guarantee the continuity of this economically important species in the region.

          Resumen El ronco blanco (Haemulon plumierii) ha ganado relevancia como recurso alternativo a las pesquerías de la costa norte de la península de Yucatán; sin embargo, el conocimiento de su biología en la región es escaso. Así, para explorar la biología reproductiva de H. plumierii se capturaron un total de 355 ejemplares con línea de mano y cebo, desde septiembre de 2015 hasta noviembre de 2016, con el fin de realizar análisis histológico de las gónadas. La muestra estuvo representada por 233 machos y 122 hembras, a diferencia de la proporción de sexos 1:1 (1 hembra por 2.1 machos). La temporada reproductiva ocurrió de febrero a agosto con un pico máximo en mayo. La talla promedio de madurez sexual (L50) se estimó en 15.15 y 15.22 cm (LT) para machos y hembras, respectivamente. La fecundidad por lotes osciló entre 9,363 y 42,371 huevos por lote, con un promedio de 26,558 huevos. Se observaron varias características de la biología reproductiva en H. plumierii, como la estacionalidad del desove en primavera, la talla de madurez sexual, el desarrollo asincrónico de ovocitos con una fecundidad indeterminada y el desove por lotes. Este tipo de información puede orientar propuestas para futuras medidas de manejo pesquero sostenible que puedan garantizar la continuidad de esta especie de importancia económica en la región.
