“…Para la captura se utilizaron atarraya (3 m de largo y 2,5 cm de luz de malla) y redes de enmalle (60 m de largo y de 7,0; 7,6; 8,9 y 10,2 cm de luz de malla). Se realizaron entre 40 y 50 lances de atarraya por día entre las 16:00 y 19:30 h. Las redes de enmalle operaron de 19:00 a 07:00 h del día siguiente (González-Sansón et al, 2014a, 2014b. En cada individuo se registró la longitud total (Lt; ±0,1 cm) y peso total (Pt; ±0,1 g).…”

RESUMEN. La lisaMugil curema tiene amplia distribución en América, habitando sistemas costeros y estuarinos. Es un recurso con importancia pesquera en varias regiones del Pacífico mexicano. El objetivo del presente trabajo es describir aspectos reproductivos de M. curema durante un ciclo anual. Se realizaron muestreos mensuales con redes y atarraya de febrero 2011 a enero 2012 en la Laguna Barra de Navidad, Jalisco, México. Se analizaron 495 ejemplares, a los cuales se les midió la longitud y el peso total. De cada ejemplar se extrajeron las gónadas, se pesaron, clasificaron según su maduración y se procesaron para histología. Se capturaron ejemplares entre 10,3 y 38,5 cm, con promedio de 26,1 cm. Se identificaron 375 hembras con promedio de 27,2 cm y 110 machos con promedio de 23,4 cm. El número de hembras dominó de manera significativa en la muestra total, por mes y por clase de longitud. Los valores máximos del índice gonadosomático ocurrieron en abril, agosto y noviembre. El factor de condición presentó valores altos en varios meses coincidiendo en ambos sexos. En la ovogénesis se identificaron seis fases de desarrollo de los ovocitos y debido a la gran cantidad de ovocitos con crecimiento primario y en vitelogénesis 2 y 3, el patrón de desarrollo fue sincrónico por grupos con desove total. La longitud promedio de madurez (L50) de machos fue de 21,7 cm y de hembras de 24,5 cm. Contrastando estas dos últimas longitudes con las de captura, se sugiere que más del 50% de los organismos capturados son individuos que se reprodujeron al menos una vez. Palabras clave: Mugil curema, lisa, índice gonadosomático, histología, madurez gonadal, México. Reproductive aspects of Mugil curema (Mugiliformes: Mugilidae) in the Barra deNavidad coastal lagoon, Jalisco, Mexico ABSTRACT. The white mullet Mugil curema is broadly distributed in America inhabiting coastal and estuarine systems. It is an economically important fishery resource in several regions of the Mexican Pacific. The goal of this research was the description of several reproductive aspects of Mugil curema during an annual cycle. Fish were sampled monthly with gill and cast nets from February 2011 to January 2012 in the coastal lagoon Barra de Navidad, Jalisco, Mexico. A total of 495 fish were analyzed. Total length and weight were measured for each specimen and gonads were collected, weighted, classified after their maturation stage and preserved for histological analyses. Caught fish were between 10.3 and 38.5 cm total length with a mean of 26.1 cm. A total of 375 individuals were classified as females with a mean total length of 27.2 cm while 110 fish were classified as males with a mean total length of 23.4 cm. Females dominated by numbers in the total sample, monthly and by length classes. Highest values of the gonadosomatic index occurred in April, August and November. Condition factor showed high values in several months and its trend along the year was similar in both sexes. Six stages were identified during the oogenesis and, due to the high quantity of p...

“…The LWR parameters reported in this contribution are based mainly on juveniles, and therefore can change according to ontogenetic development, sex, diet, and factors such as habitat and season (González‐Sansón et al., ; Moreno‐Sánchez, Luch‐Cota, Hernández‐Olalde, López‐Rasgado, & Abitia‐Cárdenas, ; Wootton, ).…”

Summary Length–weight relationship (LWR) parameters were determined for 20 fish species belonging to 14 genera and seven families. The fishes were collected monthly (May 2013 to February 2014) by soft‐bottom trawls in Bahía de Matanchén, southeast of the Gulf of California. Sizes ranged between 5.5 and 36.0 cm total length (TL) and weighed between 1 and 901 g. The allometric coefficient (b) of the LWR varied from 2.638 for Chloroscombrus orqueta to 3.668 for Neopisthopterus tropicus. This is the first report of LWR estimations for 15 of the species.

“…Two papers were found which report limited information about fish lengths of some species in coastal lagoons (Amezcua-Linares, 1977;Mendoza, Castillo-Rivera, Zárate-Hernández, & Ortiz-Burgos, 2009) but the majority of studies were not focused in documenting size composition of fishes. Only recent research in Barra de Navidad lagoon has yielded the first quantitative data on fish lengths suggesting a dominance of juvenile fish in these systems (González-Sansón et al, 2014.…”

“…This lagoon has been declared Ramsar site (wetland of international importance) and has been included among the 81 mangrove sites with biological relevance and ecological rehabilitation needs by Mexico's National Commission for the Knowledge and Use of Biodiversity (Rodríguez-Zúñiga et al, 2013). Fish fauna in this lagoon is composed in a great proportion (> 70 %) by species in juvenile stages (González-Sansón et al, 2014) and it is highly probable that this wetland could be an important nursery area for many marine species with commercial and ecological relevance (González-Sansón et al, 2016).…”

Barra de Navidad lagoon (BNL) is one of the main coastal wetlands in the coast of the State of Jalisco, Mexico. It is a Ramsar site (wetland of international importance) and has been included among the 81 mangrove sites with biological relevance and ecological rehabilitation needs in Mexico. Although fish fauna composition is well known in BNL, little evidence exists that support seasonal and spatial changes of fish assemblages’ structure. The hypothesis tested in this study was that there are significant seasonal and spatial changes in BNL fish assemblages’ composition which can be explained, at least partially, by changes in salinity, water temperature and sediment’s granulometry. Fish assemblages were sampled monthly from October 2012 to September 2013 at four zones of BNL, using gill nets (7.62 mm stretched mesh). A sample was taken every month in a randomly selected area of each zone. Prior to each sampling operation, water salinity and temperature were measured using an YSI-30 probe. Samples of sediment were collected with a Van Veen grab sampler in three randomly selected points of each zone for granulometry and organic matter analyses. A total of 2 026 individuals belonging to 48 species were collected. Slightly more than 90 % of all caught fish belonged to nine species: Peruvian mojarra (Diapterus brevirostris), Pacific crevalle-jack (Caranx caninus), White mullet (Mugil curema), Blue sea-catfish (Ariopsis guatemalensis), Oval flounder (Syacium ovale), Pacific lined sole (Achirus mazatlanus), Yellowfin mojarra (Gerres simillimus), Pacific bumper (Chloroscombrus orqueta) and Freckled porcupinefish (Diodon holocanthus). Generalized linear models yielded significant differences among zones for the mean abundance of each of these nine species, but only in two cases seasonal differences were significant (D. brevisrostris and C. caninus). Permutational multivariate analysis of variance yielded also significant differences among zones and between seasons for the composition of the fish assemblage. Redundancy analysis using salinity, temperature and percentage mud in sediment as environmental variables, showed that fish assemblage’s composition varies along two main gradients defined by mud fraction of sediments in a small spatial scale (~ 3 km) and salinity in a seasonal scale. Percentage of variation explained by canonical axes was less than 25 %, indicating that other factors could be influencing changes in assemblage composition. As most species appear as juveniles in the lagoon, fluctuations in their abundances could be linked, at least partially, with recruitment events.
