Reproductive studies of an intertidal free-spawning population of Chiton articulatus (Mollusca: Polyplacophora) from Puerto Angel, Oaxaca, Mexico were undertaken during 2011. We used gonad histology and gonadal indices to assess the relative gonad expenditure of the sexes (RGES) and other reproductive traits, accounting for individual and seasonal variation within this population. At this location, C. articulatus is gonochoric, without sexual dimorphism, except internally by gonad colour (testis is ‘salmon’ coloured and ovary olive green). Annual and monthly sex ratios (m/f) do not differ significantly from 1:1. Highest population-level gonadosomatic index (GSI) corresponded to maximum (peak) ripe stage (i.e. maximum gonad investment), with a first peak in May with a high value (8.4 ± 0.5) and a second peak during August-September with a lower value (4.7 ± 0.3). GSI fluctuated throughout year implying that gonad expenditure may be seasonally constrained, but with overall synchrony between sexes of ripe and spawning stages. July to December was the main reproductive season with some facultative spawning occurring off-season. Ripe and spawning RGES did not differ between sexes, suggesting that either sperm competition is intense and/or that sperm limitation is high. Early spawning individuals may quickly replenish their gametes for a second phase of gamete release later. Abbreviations: RGES: relative gonad expenditure of the sexes; GSI: gonadosomatic index; GDS: gonad developmental stages; MiMI: microscopic maturity index; SST: sea-surface temperature.

Las condiciones climáticas y oceánicas determinan el patrón de distribución de la merluza del Pacífico (Merluccius productus). El presente trabajo tuvo como objetivo conocer la relación espaciotemporal entre la distribución y la abundancia de la merluza del Pacífico y el ambiente en el golfo de California. Se analizó la información obtenida de 6 cruceros de investigación realizados entre 2014 y 2019. Los resultados mostraron que la merluza del golfo de California alcanza tallas de 105 cm de longitud total y presenta dimorfismo sexual a tallas >73 cm de longitud total. La mayor biomasa del recurso (68,260.37 t) se encontró en febrero de 2019 entre los 200 y 300 m de profundidad, y la menor, en octubre de 2016 (6,917.80 t) a profundidades de 100–150 m. Los centros de abundancia se localizaron a temperaturas de fondo de entre 13 y 14 °C, al norte de la isla Ángel de la Guarda y entre las grandes islas (isla Tiburón e isla Ángel de la Guarda). Al ajustar modelos aditivos generalizados entre las capturas de merluza de cada estación y distintas variables ambientales, espaciales y temporales, se encontró que la temperatura de fondo fue la variable que mejor describió estos centros de abundancia.
