“…This vulnerability analysis was specific to a particular fishery and fishing gear type in this study. However, it is important to consider the multi-species and multi-gear character of the fisheries in Mexico (Arce-Acosta et al, 2018). Evaluating the cumulative effects of multiple fisheries affecting one species was beyond our scope.…”

The main key drivers of vulnerability for marine species are anthropogenic stressors, ranging from pollution and fishing to climate change. The widely documented impacts of fishing activities on marine species, the growing concern about the population status of many marine species, and the increase in per capita consumption of marine products worldwide have led to the development of environmentally responsible fishing standards and initiatives to inform consumers about the health status of the species. In Mexico, fishing is a vital source of jobs and food security for many coastal communities, but the population status of many species of commercial importance has not been evaluated. Management efforts and fisheries certification procedures and standards to achieve the sustainability of many Mexican fisheries are hindered by a lack of biological and fishery data for many species. In this study, a risk assessment methodology for data-limited fisheries, a Productivity, and Susceptibility Analysis was used to estimate the relative vulnerability of marine invertebrates and fishes commercially important in Mexico to fishing. Ninety-eight invertebrates, 66 elasmobranchs, and 367 bony fish were analyzed. The vulnerability among the 531 evaluated species is high for 115 (22%), moderate for 113 (21%), and low for 303 (57%). The most vulnerable species are the Mexican geoduck (Panopea globosa) and the Black Sea Cucumber (Holothuria atra) for invertebrates, the Spiny butterfly ray (Gymnura altavela) among elasmobranches, and the Black-and-yellow rockfish (Sebastes chrysomelas) for bony fishes. This study provides a first screening of the many species potentially affected by fisheries, prioritizes marine species for future research and management efforts, identifies the main data gaps, and sets the baseline for future research efforts and management. Furthermore, the results could improve market-based approaches like eco-labeling initiatives and the Responsible Seafood Consumption Guide, developed by Mexican authorities in collaboration with Comunidad and Biodiversidad (COBI, a civil society organization), to inform consumers about the origin and sustainability of fishery products.

“…The Gulf of California is a highly productive system that supports the most economically important fisheries in Mexico (Cisneros-Mata 2010). Most coastal communities in the Gulf of California depend on a small-scale fishing sector that targets over 80 species of fish, sharks, and invertebrates (Turk-Boyer et al 2014a); these fisheries are highly adaptive and flexible, and their multispecific and multigear character allows fishers to maximize profitability (Arce-Acosta et al 2018). Changes in the marine environment of the Gulf of California, including decreases in catch composition and mean trophic level (Sala et al 2004), maximum fish size (Sala et al 2004; Sáenz-Arroyo et al 2005b), and species abundance (Sáenz-Arroyo et al 2005a, b; Lozano-Montes et al 2008; Ainsworth 2011), have been linked to overfishing.…”

Coastal wetlands are rich and productive ecosystems that historically have been used by small-scale fisheries due to their role as refuges, feeding, and nursery habitats for commercial target species. We used wetland resource users' Local Ecological Knowledge to document historical patterns of commercial species abundance, areas of fishing importance, trophic level, and species richness and composition in coastal wetlands in the Northern Gulf of California, Mexico. We also reconstructed the environmental history of coastal wetlands in this region from bibliographic sources and photographic records, to document impacts that could have affected coastal fisheries. We found a consistent downward trend in target species abundance; the decrease was perceived as more pronounced by fishers that began fishing in or prior to the 1950's, pointing to shifting baselines, the failure for resource users to recognize environmental change and accept degraded states as normal. Areas of fishing importance within coastal wetlands also decreased through time. Trophic level of catch showed no distinct pattern across wetland sites or time. Perceived species richness and composition increased with wetland size. Our analysis of the small-scale use of coastal wetlands in the Northern Gulf is relevant to food security and can provide insight into how local populations adapt to depleted coastal food webs.

“…For example, a fishing strategy was classified to determine the fleet capacity and the fishing activities of a similar catch composition, in order to indicate targets [26][27][28][29][30][31][32]. This is potentially useful in revealing the fishing strategy and the fishermen's behavior by integrating the social and economic variables, fishing patterns, and spatial and temporal information [6,19,21,[33][34][35][36][37]. A mixed fishery (such as the trawl fisheries) could be better described by grouping similar features (i.e., métiers) through the exploration of the fishery structure.…”

Application of Métier-Based Approaches for Spatial Planning and Management: A Case Study on a Mixed Trawl Fishery in Taiwan

Mixed fisheries refer to fishing activities that catch more than one species simultaneously, and a species may be fished using different gear. A trawl fishery shares these features to exploit multiple species simultaneously, with diverse fishing gear and strategies. The situation becomes more complex when interactions among fleet dynamics, fishing activities, and fishery resources are involved and influence each other. Information regarding the operational patterns may be hidden in a set of long-term big data. This study aims to investigate the fishery structure and fleet dynamics of trawl fisheries in Taiwan for spatial planning and management, based on a long-term dataset from a management system that collects information by using voyage data recorders (VDR) and dockside observers. We applied a two-step data mining process with a clustering algorithm to classify the main groups of fishery resources and then identified 18 catch métiers based on catch composition. The target species, operation pattern, and fishing season were determined for each métier, and associated with the relevant fishery resources and the fishing gear used. Additionally, fishing effects on target species were estimated using information on fishing grounds and trajectories from VDR. The métier-based approach was successfully applied to define the six major fishery resources targeted by trawlers. We examined the key features of fishing activity associated with catch composition and spatial-temporal fishing metrics, which could be used to provide suggestions for the spatial planning and management of the mixed trawl fishery in the offshore waters of Taiwan.
