Summary: Connectivity studies in the Gulf of California are an important tool for improving the use and management of the gulf's natural resources. The goal of this work was to study the three-dimensional connectivity in the northern Gulf of California during two representative months of summer when most local marine species spawn. Passive particles were advected for eight weeks in a three-dimensional current field generated by a three-dimensional baroclinic numerical model. The results indicate that the locations of greatest particle retention were the Upper Gulf and the Seasonal Eddy. The Seasonal Eddy corresponded to the area of largest particle catchment because the continental coastal current carries most particles released in the Midriff Archipelago region; subsequently these particles were entrained in the seasonal cyclonic eddy, causing most of them to remain within it. We conclude that the continental coastal current and the Seasonal Eddy control the connectivity patterns in the northern Gulf of California.Keywords: connectivity; northern Gulf of California; summer; HAMSOM; retention; continental coastal current; Seasonal Eddy. Conectividad tridimensional durante el verano en el norte del Golfo de CaliforniaResumen: Los estudios de conectividad en el Golfo de California (GC) son una herramienta importante para mejorar el uso y la gestión de los recursos naturales del golfo. El objetivo de este trabajo fue estudiar la conectividad tridimensional en el norte del Golfo de California (NGC) durante dos meses representativos de verano, ya que es la temporada con mayor desove de especies marinas. Se advectaron partículas pasivas durante ocho semanas en un campo de corrientes tridimensional generado por un modelo numérico baroclínico tridimensional. Los resultados indicaron que los lugares con mayor retención de las partículas fueron el Alto Golfo (UG) y el Remolino Estacional (SE). A su vez, SE fue el área de máxima captación de partículas debido a que la corriente costera continental transporta la mayoría de las partículas liberadas en las localidades ubicadas en la zona de las Grandes Islas, posteriormente estas partículas son atrapadas por el remolino ciclónico estacional lo que provocó que la mayoría de las partículas liberadas se queden dentro de éste. Por último, concluimos que la corriente costera continental y el remolino estacional controlan los patrones de conectividad en el NGC.Palabras clave: conectividad; norte del Golfo de California; verano; HAMSOM; retención; corriente costera continental; remolino estacional.

“…Another key factor to consider in understanding larval dispersal patterns is the Planktonic Larval Duration (PLD) of focal species. Our validated oceanographic models for the GOC predict that the average distance traveled by passive larvae is a function of their PLD varying from [ 20 to 80 km (PLD 7 days) up to [ 200 km (PLD 28-60 days, Online Resource 7) such that recommendations for reserve spacing might differ between taxonomic groups with different PLDs (Soria et al 2014). Fish species associated with different habitats also seem to show statistically different dispersal profiles, with species from soft bottom habitats dispersing longer distances than those in other habitat types like rocky reefs (Anadon et al 2013).…”

“…5). In such a highly asymmetric current system, it is, therefore, very important that more marine reserves are located upstream of the direction of the flow during the spawning season of target species, since these areas act as larval sources to sustain metapopulations of those species Many commercially important fisheries species studied to date spawn during spring and/or summer (Cudney-Bueno et al 2009;Soria et al 2014), so it will be important to protect upstream sources of larvae during this period (e.g. in permanent or seasonal marine reserves).…”

“…Thus as the distance between reserves increases, the amount of larvae they exchange (larval connectivity) decreases. However, given the strong, consistent asymmetric currents in the GOC, geographic distance alone is a poor predictor of ecological and genetic connectivity, because oceanographic distance follows the direction of the predominant current flow , 2018Soria et al 2014;Lodeiros et al 2016). Therefore, marine reserves in the GOC should be spaced using mean dispersal distances in the direction of the predominant flow (Table 1, Guideline 10).…”

No-take marine reserves can be powerful management tools, but only if they are well designed and effectively managed. We review how ecological guidelines for improving marine reserve design can be adapted based on an area's unique evolutionary, oceanic, and ecological characteristics in the Gulf of California, Mexico. We provide ecological guidelines to maximize benefits for fisheries management, biodiversity conservation and climate change adaptation. These guidelines include: representing 30% of each major habitat (and multiple examples of each) in marine reserves within each of three biogeographic subregions; protecting critical areas in the life cycle of focal species (spawning and nursery areas) and sites with unique biodiversity; and establishing reserves in areas where local threats can be managed effectively. Given that strong, asymmetric oceanic currents reverse direction twice a year, to maximize 123Rev Fish Biol Fisheries (2018) 28:749-776 https://doi.org/10.1007/s11160-018-9529-y( 0123456789().,-volV) (0123456789().,-volV)

Resumen.-La almeja de sifón Panopea globosa es una especie de importancia comercial por su alta demanda en el mercado de Asia. El propósito de este estudio fue analizar el efecto de la concentración de clorofila, temperatura superficial del mar, turbidez y ciclo de mareas en la estimación de la densidad, distribución espacial, y estructura poblacional de la almeja P. globosa en la región central del Golfo de California usando datos de satélite y observaciones de campo. Los organismos fueron recolectados mediante buceo semi-autónomo, entre noviembre 2009 y enero 2011. Se recolectaron un total de 10.114 almejas con un peso promedio de 997 ± 212 g (80%  800 g), y una longitud promedio de 132 ± 12,5 mm (80% de los organismos recolectados estuvieron por arriba de 130 mm, que es la talla mínima legal de pesca). La densidad de P. globosa del área de estudio presentó diferencias significativas entre las 3 agregaciones identificadas con alta densidad, pero la densidad no estuvo correlacionada con ninguno de los factores ambientales considerados.Palabras clave: Pesquería, manejo, Golfo de California, almeja de sifón Abstract.-The geoduck clam Panopea globosa is a commercially important species because of its high market demand, particularly in Asia. The aim of this study was to analyze the effect of chlorophyll concentration, sea surface temperature, turbidity, and tidal cycle on density estimation, spatial distribution, and population structure of P. globosa in the central Gulf of California using remote sensing and field survey data. Specimen collections were conducted through semiautonomous diving from November 2009 to January 2011. A total of 10,114 clams were obtained with an average weight of 997 ± 212 g (80% 800 g), and an average length of 132 ± 12.5 mm (80% of all collected clams exceeded 130 mm, the minimum legal fishing size). P. globosa distribution displayed significant differences among the 3 patches of high density in the study area, but density was poorly correlated with the environmental factors.
