“…Meanwhile, ocean acidification in the GOC is predicted to increase, stemming from a decrease of -0.25 to -0.4 pH units. Sea level trends in the GOC from 1993 to present averaged an increase of 2.5 ± 1.1 mm/year, which is compatible with global trends (Paez-Osuna et al 2016). However sea level increases in the deeper central GOC were less (0.1 ± 0.3 mm/year) than in the Southern GOC (0.8 ± 0.8 mm/year) and the shallow Upper GOC (2.0 ± 0.4 mm/year) (Paez-Osuna et al 2016).…”

“…In contrast, land based threats are much higher along the east coast of the GOC, in part driven by land-based nutrient pollution from farming activities that represent a potential risk to marine areas (Alvarez-Romero et al 2015). Many coastal lagoons along the eastern margin of the GOC also exhibit signs of increased sedimentation and growing volumes of agricultural runoff and eutrophication from shrimp farming (Paez-Osuna et al 2016), while coastal wetlands have been steadily receding due to conversion to tourism developments and aquaculture (Carvajal et al 2010). …”

“…Oceanographically, the GOC is characterized by a series of gyres that consistently reverse directions twice a year (Marinone et al 2011;. Strong tidal mixing and wind-driven coastal upwelling result in high year-round primary productivity (Lavin and Marinone 2003) with * 700,000 tons of seafood produced annually (Paez-Osuna et al 2016) including * 40% bycatch (Cisneros-Montemayor et al 2013). This production represents 40-77% of the volume of Mexico's fisheries and about 50% of its value (330 million USD in 2014).…”

“…This production represents 40-77% of the volume of Mexico's fisheries and about 50% of its value (330 million USD in 2014). The GOC supports at least half of nation's fisheries-related jobs (a conservative estimate of * 32,600), with an estimated 937 large and [ 12,500 small fishing vessels (pangas) in operation (Paez-Osuna et al 2016). Marine ecotourism in the GOC is another important economic activity, attracting * 900,000 people every year who spend over 500 million USD (Spalding et al 2016).…”

“…hurricanes, coral bleaching, disease outbreaks, land-based run-off triggered by hurricanes and harmful algal blooms) can have serious impacts on marine ecosystems in the GOC (Reyes-Bonilla et al 2002;Alvarez-Romero et al 2015;Paez-Osuna et al 2016). Since it is not possible to predict which areas are most likely to be affected by these disturbances, we recommend that at least three examples of each major habitat should be protected within marine reserves in each of the three biogeographic subregions.…”

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)

Over the past two decades, the Gulf of California (GOC) has experienced three strong El Niño events ), each of which was followed by a drastic reduction in mantle length of mature Humboldt squid, Dosidicus gigas (from >60 cm to <20 cm). However, it is unclear how the oceanographic changes associated with strong El Niño events affected the midwater organisms on which D. gigas feed, limiting our ability to assess the relative importance of temperature and food availability in the phenotypic response of D. gigas to environmental variability. We quantified the diet of D. gigas in the GOC before, during, and following the past three El Niño events and found that although its diet varied little across a large range of body sizes (8-85 cm), significant and predictable diet variability was observed with respect to sea surface temperature and chlorophyll-a concentration. Consumption of large numbers of relatively small, high calorie prey in both relatively cool (anchovies) and relatively warm, productive conditions (myctophids) is likely necessary to support growth to large body sizes before maturation. When warm, unproductive conditions prevailed in the GOC, only small squid were present and had diets dominated by euphausiids and pteropods, prey with relatively low caloric value. Using a time series of diet data, this work provides unique insights into the response of a midwater forage community to oceanographic variability and the effects of environmental variability on the trophic ecology of an oceanic predator.
