Seasonal abundance and selectivity of the main crustacean species associated with blue crab fishing was studied at the port of Sisal, Yucatan, Mexico. For this purpose, 52 crab traps were used, which were divided into four parallel transects placed 100, 150, 200 and 250 m of the shoreline. Each transect consisted of 13 traps 20 m from each other. Traps were set at dusk and checked at dawn, standardizing the fishing effort to 17 hours/trap/day. A total of 832 organisms from eight species were caught; however, the study was conducted with four commercially important species: Blue Crab (Callinectes sapidus), white crab (C. similis), spider crab (Libinia dubia) and stone crab (Menippe mercenaria), accounting for 60.7%, 13.3%, 11.4%, and 11.6% of the catch, respectively. When dividing the total catch between climatic seasons (dry, rainy, and north wind), significant differences were detected in catch per unit effort (kg trap). The highest catch of C. sapidus and L. dubia was recorded in the dry season, while C. similis and M. mercenaria highest catch was in the north wind season. Most species showed a sex ratio different from 1:1, except for C. similis. Regarding selectivity or size at first catch (L50) values were 148, 90, 60, and 94 mm carapace width for C. sapidus, C. similis, L. dubia and M. mercenaria, respectively. Se estudiaron la abundancia estacional y la selectividad de las principales especies de crustáceos asociadas a la pesca de la jaiba azul, en el puerto de Sisal, Yucatán, México. Para ello se utilizaron 52 trampas jaiberas, divididas en cuatro transectos colocados de manera paralela, a una distancia de 100, 150, 200 y 250 m de la línea de costa. Cada transecto estuvo conformado por 13 trampas, con una distancia de 20 m una de otra. Las trampas se colocaron al atardecer y se revisaron al amanecer, estandarizando el esfuerzo de pesca en 17 horas/trampa/día. En total se capturaron 832 organismos de ocho especies, sin embargo, el estudio se realizó con cuatro especies de importancia comercial: jaiba azul (Callinectes sapidus), jaiba blanca (C. similis), cangrejo araña (Libinia dubia) y cangrejo moro (Menippe mercenaria), representando el 60.7, 13.3, 11.4 y 11.6% de las capturas, respectivamente. Al dividir la captura total entre épocas climáticas(secas, lluvias y nortes), se detectaron diferencias significativas en la captura por unidad de esfuerzo (kg/trampa).C. sapidus y L. dubia registraron su máxima captura en la época de secas, sin embargo, C. similis y M. mercenaria la presentaron en la época de nortes. La mayoría de las especies presentaron una proporción sexual diferente a una relación 1:1, con excepción de C. similis. Con respecto a la selectividad o talla de primera captura (L50), los valores fueron de 148, 90, 60 y 94 mm de ancho de caparazón, para C. sapidus, C. similis, L. dubia y M. mercenaria, respectivamente. Foram estudadas a abundância estacional e a seletividade das principais espécies de crustáceos associadas à pesca do siri-azul, no porto de Sisal, Yucatán, México. Para isso, utilizaram-se 52 armadilhas, divididas em quatro transeções dispostos de maneira paralela, a uma distância de 100, 150, 200 e 250 m da linha costeira. Cada transeção esteve conformada por 13 armadilhas, com uma distância de 20 m uma de outra. As armadilhas foram colocadas ao entardecer e revisadas ao amanhecer, estandardizando o esforço de pesca em 17 horas/armadilha/dia. No total foram capturados 832 organismos de oito espécies, porém, o estudo foi realizado com quatro espécies de importância comercial: siri-azul (Callinectes sapidus), siri anão (C. similis), caranguejo aranha (Libinia dubia) e caranguejo moro (Menippe mercenaria), representando 60.7, 13.3, 11.4 e 11.6% das capturas, respectivamente. Ao dividir a captura total entre épocas climáticas (secas, chuvas e nortes), detectaram-se diferenças significativas na captura por unidade de esforço (kg/armadilha). C. sapidus e L. dubia registraram sua máxima captura na época de secas, porém C. similis e M. mercenaria na época de nortes. A maioria das espécies apresentaram uma proporção sexual diferente a uma relação 1:1, com exceção de C. similis. Com relação à seletividade ou tamanho de primeira captura (L50), os valores foram de 148, 90, 60 e 94 mm de largura de carapaça, para C. sapidus, C. similis, L. dubia e M. mercenaria, respectivamente.
