“…Temperature and salinity in Las Guásimas showed a well-defined semiarid zone seasonality, which agrees with Hernández & Arreola (2007) and Ontiveros (2011). The temperature was influenced mainly by the air temperature with greater variations at 14°C (García 1988).…”

Resumen.-Las lagunas costeras se caracterizan por su alta diversidad, riqueza y abundancia de peces, las cuales pueden ser modificadas por la variabilidad de las condiciones ambientales. El presente estudio tiene como objetivo describir la estructura de la comunidad de peces y relacionar su variabilidad estacional con los parámetros de temperatura y salinidad en una laguna costera. Durante 6 campañas de muestreo se recolectaron 4.199 peces, agrupados en 95 especies. Los resultados indicaron que la riqueza, diversidad y equidad tuvieron un comportamiento estacional similar con valores mayores durante otoño 2010, primavera 2011 y 2012; la abundancia fue mayor en otoño 2010, verano 2011 y 2012 y la biomasa en otoño 2010 y verano 2011. La relación de la temperatura y salinidad a través del análisis RDA con los parámetros ecológicos, indicó que algunas de las especies dominantes son de afinidad cálida y otras de afinidad fría. Mientras que la riqueza y diversidad se incrementan durante temporadas frías, la biomasa y equidad aumentan en las temporadas de mayor salinidad; por su parte la abundancia se incrementa en temporadas cálidas. Las curvas ABC mostraron estrés moderado durante invierno y verano de 2012 y el MDS indicó la formación de 4 grupos, dos integrados por 2 periodos de muestreo y dos por uno solo de ellos. Los parámetros ecológicos presentaron variaciones estacionales debido a la influencia de los cambios en temperatura y salinidad. Palabras clave: Variabilidad estacional, parámetros ecológicos, comunidad de peces, laguna costeraAbstract.-Coastal lagoons are characterized by high diversity, richness, and abundance of fishes, which can be modified by high variability of environmental conditions. The present study aims to describe the structure of the fish community and related its seasonal variability with temperature and salinity in a coastal lagoon. During 6 seasonal sampling campaigns 4,199 fish were collected and grouped in 95 species. The results indicated that richness, diversity and evenness indices showed similar pattern with higher values in autumn 2010, spring 2011 and 2012, abundance was higher in autumn 2010, summer 2011 and 2012 and biomass in autumn 2010 and summer 2011. Relationship of temperature and salinity through the RDA analysis with ecological parameters indicated that some dominant species are of warm affinity and other of cold affinity. Richness and diversity increase during cold seasons, while biomass and evenness increase in seasons of higher salinity and abundance increases in warm seasons. The ABC curves showed moderate stress in winter and summer 2012 and MDS indicate the formation of 4 groups, two integrated by 2 sampling periods and two by single sampling period. Ecological parameters showed seasonal variations because they are influenced by changes of temperature and salinity.

“…In wild populations, Fischer & Wolff (2006) reported an asymptotic CW of 142 mm for males. Hernández & Arreola-Lizárraga (2007) mentioned an asymptotic CW of 140 mm for both sexes combined; these authors attributed the growth differences to the different sampling methods, whereas in the present study growth models were the basis for growth estimations. All the previous studies used the von Bertalanffy growth model.…”

“…Growth of Callinectes arcuatus has been described by Paul (1982), Fischer & Wolff (2006) and Hernández & Arreola-Lizárraga (2007). In addition, Dittel & Epifanio (1984) and Vega-Villasante et al (2007) provided information on laboratory-reared animals.…”

“…As far as we know no previous study has used the Schnute (1981) growth model to describe growth in any Callinectes species, despite its wide acceptance in the literature on fish growth (e.g., Katsanevakis, 2006). All other studies of C. arcuatus have directly fitted the VBGM (Fischer & Wolff, 2006;Hernández & Arreola-Lizárraga, 2007;Ramos-Cruz, 2008) rather than also examining alternative growth functions. This is especially relevant when much of the early life history incorporates linear growth, which is not consistent with the VBGM.…”

ABSTRACT. This study describes the growth parameters of males of the blue crab Callinectes arcuatus based on samples from a coastal lagoon in the southern Gulf of California and from individuals raised under controlled conditions. The models assessed were the four variants of the Schnute growth model and a special case of the von Bertalanffy model (VBGM). The Akaike information criterion was used to select the best model. The models with the best fit were Case 3 of the Schnute model for the separated wild and captive-reared data sets, but the combined data set fit better to the VBGM function, indicating linear growth, and Case 5 suggesting asymptotic growth of the C. arcuatus. Our results depend on the assumption that reared and fished individuals were covering the entire benthic growth period. It is concluded that 1) modeling growth by treating cohorts as individuals yields accurate estimations of k and the L∞ equivalent that can be used directly in stock assessment models, and (2) the ranges of validity of the best growth models for C. arcuatus growing in wild and cultured environments overlapped in the size range of 62 to 85 mm of carapace/width, but they have a continuity that represents blue crab growth throughout their benthic life. Keywords: Callinectes arcuatus, growth, multi-model, wild population, controlled conditions, Gulf of California. Estimación de los parámetros de crecimiento de los machos de la jaiba azulCallinectes arcuatus (Brachyura: Portunidae) del Golfo de California, utilizando el modelo de Schnute RESUMEN. Se describen los parámetros de crecimiento de machos de la jaiba azul Callinectes arcuatus, de una laguna costera del sureste del Golfo de California y de ejemplares mantenidos en condiciones controladas. Los modelos evaluados fueron las cuatro variantes de Schnute y el de von Bertalanffy (VBGM). El criterio utilizado para seleccionar el mejor modelo fue el de Akaike. Los modelos que presentaron un mejor ajuste fueron el Caso 3 de Schnute para datos separados, del medio natural o en condiciones controladas, indicando una relación lineal; y el Caso 5 de VBGM para los datos combinados, lo que sugiere un crecimiento asintótico para C. arcuatus. Estos resultados corresponden al análisis de los datos conjuntos de los organismos obtenidos del medio natural y de los estanques en condiciones controladas. Se concluye que 1) el modelo de crecimiento obtenido a través del análisis de las cohortes individuales presenta estimaciones adecuadas de k y L∞, que se puede considerar equivalente al utilizado en modelos evaluación de stocks, y 2) los rangos de validez de los mejores modelos de crecimiento para la jaiba azul C. arcuatus en el medio natural y en condiciones de cultivo coinciden en el rango de tamaño de 62 a 85 mm de ancho de cefalotórax, teniendo una continuidad que ajusta adecuadamente su crecimiento durante su etapa de vida bentónica.

“…Likewise, significant size distribution differences were found between C. arcuatus and C. bellicosus captured both by artisanal fishery and shrimp fleet, concluding that the shrimp fleet (industrial) extracts mostly organisms of these 2 species in smaller sizes (50-120 mm CW) while smaller ships (artisanal) extract larger ones (75-155 mm CW). Hernández & Arreola-Lizárraga (2007) reported size distribution differences in C. arcuatus and C. bellicosus obtained from samplings performed with trawling nets in a coastal lagoon (Las Guásimas, Sonora) and in those analyzed by Molina-Ocampo (2001) and Nevárez-Martínez et al (2003) from commercial captures with traps. To conclude, average sizes captured with trawling nets for C. arcuatus and C. bellicosus were 18 and 42 mm, respectively, whereas those coming from commercial captures were 65 and 72 mm, respectively.…”
