Despite the protection status of the marine area in Los Arcos, it has experienced reef deterioration associated with tourism activities. Therefore, this study aimed to analyze SCUBA divers’ impacts by quantifying and typifying their contact with the seabed, and to determine if the diving leader’s performance is related to the behavior of the divers being guided. The number and type of impacts on the seabed were counted and categorized as intentional and non-intentional. A total of 9811 contacts were made by 101 divers. The highest frequency type of non-intentional contact identified was “lifting sediment”, following by non-intentional—fins. The “hands” intentional contact type was found to occur most often. The highest frequency of total contacts per diver was “very high” (31.7%). By analyzing the profile of the divers related to their certification level, number of dives, SCUBA center attended, and leader, it was possible to establish a relationship between the number of contacts made by the leader and the number of contacts made by the divers guided by each leader. Our findings suggest the need for a joint approach of key players toward good practices to highlight the important role of diving leaders on their clients’ behavior, and thus preserve the ecological and aesthetic qualities of the dive site.

Artisanal fishing is a very important activity for the subsistence of coastal inhabitants in Latin American countries. Increasingly, what has traditionally been a rural activity is being enveloped by urban expansion, resulting in urban-based artisanal fishers. We administered 98 questionnaires to artisanal fishers along the Jalisco coast of the Bahia de Banderas, on the Pacific Coast of Mexico. Approximately half of the participants belonged to each of urban (Puerto Vallarta) or rural collectives. The aim of the study was to understand the differences and similarities between urban and rural fishers with respect to demographics, fishing behaviors, assessments of past, current, and future fishing resources, attitudes towards fisheries management, and perceptions of human-environment relationships. The respondents represented an aging demographic with a low level of education. They reported catching 27 different species of fish, primarily of the Family Lutjanidae, although rural fishers reported a greater variety of species captured. Half of the respondents supplement fishing with a second form of income, a trend that is more prevalent in rural fishers. Fishers indicated that fishing was better in the past and predicted it will be poorer in the future; rural fishers were more negative about fishing conditions. Almost all fishers were concerned about the health of fish populations and three-quarters of them felt that fish populations are disappearing. Specific fishing practices were the highest cited problems facing fishing and making changes to these problems was identified to improve fishing. Half the respondents felt that there is conflict between artisanal and commercial sport fishers, but this is more prevalent in urban fishers. Respondents indicated that fishery managers need to do their job (e.g. resource monitoring, enforcement) and apply fisheries laws in order to help improve regional fisheries. Overall, concerns for a future sustainable fishery are reflected in an ecocentric view of humanity and nature by both groups, although it is often statistically greater in urban fishers. These results provide an insight into differences between urban and rural fishers that can be useful for local fisheries collectives, regional and federal fisheries management agencies, as well as global approaches to small-scale fisheries.

En México, las denominadas áreas naturales protegidas han enfrentado retos en común para lograr sus objetivos de conservación. Los conflictos resultantes desde el decreto y posterior implementación y gestión a lo largo del tiempo reclaman mayor participación de las comunidades. Con el objetivo de conocer la problemática que surge de la gestión de las áreas naturales protegidas en relación con la participación social en América Latina y con las medidas para incentivarla en favor de la conservación, se realizó una revisión sistemática de 30 documentos científicos en las bases de datos multidisciplinarias de Web of Science. Se encontró que los problemas prioritarios son la limitada participación de las comunidades locales en la toma de decisiones y escasas oportunidades referentes a otras alternativas económicas y factores políticos. Los trabajos analizados exponen la exclusión que dichas comunidades han sufrido en los procesos de toma de decisiones y gestión, así como las pocas iniciativas que hay en las áreas naturales protegidas que permitan su participación. No se encontraron medidas relevantes para incentivar la participación comunitaria, salvo proyectos de ecoturismo y propuestas de cambios en los planes de manejo para considerar los aspectos bioculturales.

El consenso de la humanidad acerca de un anhelado desarrollo llamado sustentable, trajo consigo la necesidad de desarrollar herramientas que guiaran el camino. En este contexto, dada la necesidad de prevenir y limitar el crecimiento de visitantes, el concepto de capacidad de carga (CC) se convirtió en una herramienta importante en la planificación turística. En este trabajo se realizó una investigación participativa en tres fases: determinación de la Capacidad de Carga Física (CCF), la Capacidad de Carga Real (CCR) y la Capacidad de Carga Efectiva (CCE), con el fin de establecer el número máximo de visitantes en dos playas en la bahía de Chamela. El proceso arrojó un resultado de 445 y 19,208 visitantes/día para Isla Cocinas y Playa Pérula respectivamente. Se recomienda aumentar el personal para aumentar la capacidad de gestión de los visitantes e implementar el plan para uso público como base para ordenar las actividades.

Shallow submarine hydrothermal vent systems assume differentiated environmental conditions. Some specimens of Branchiostoma californiense were found in the sediments of the influence area of the shallow hydrothermal venting in Punta Mita. This is the only lancelet species registered for the Mexican Pacific. The meristic and morphometric characteristics of the organisms first collected in unconsolidated sediments of this shallow system were reviewed, in order to determine the species. We confirm that it is the same species. This represents the first record of it for both the Banderas bay and in the influence area of a shallow hydrothermal system.

Sustainable fishing includes the socioeconomic status of fishers. We combined empirical quality of life (QOL) and subjective lived experiences methods to explore the social sustainability of artisanal fishers in five fishery collectives along the coast of Jalisco, Mexico, where the average daily income is slightly above the poverty level. The QOL scores were also related to annual catch and incomes within each collective. A QOL index is used in this study that combines importance and achievement ratings scores; the results are indicative of an acceptable QOL for fishermen. The concept of lived experiences, incorporating aspects of life relating to Mind, Body, Work and People was explored through interviews with 12 fishers. The QOL data revealed that family and friends are important indicators related to positive QOL reported by the sample, while economic indicators were not important. Although four of the five collectives perceived that the future looks worse than the present and past, there was limited correlation between catch or income and QOL. However, while the lived experiences exercise in part supported the QOL findings, in that People was the most important dimension for almost all of the fishers interviewed, negative economic gaps related to poor catches and incomes were prevalent in the Mind and Work dimensions. The findings suggest that to understand the socioeconomic component of sustainable fisheries, both of these approaches should be considered, as they can illuminate different aspects of fishers’ lives that need to be considered during the development of fisheries’ management policies.

Coastal fisheries contribute to global food security, since fish are an important source of protein for many coastal communities in the world. However, they are constrained by problems, such as weak management of fisheries and overfishing. Local communities perceive that they are fishing less, as in other fisheries in the world. The aim of this study was to evaluate the fisheries sustainability in the Jalisco coast through the fishing footprint, or fishprint (FP), based on the primary productivity required (PPR) and the appropriated surface by the activity (biocapacity). The total catch was 20,448.2 metric tons from 2002–2012, and the average footprint was calculated to be 65,458 gha/year, a figure that quadrupled in a period of 10 years; the biocapacity decreased, and the average trophic level of catches was 3.1, which implies that it has remained at average levels, resulting in a positive balance between biocapacity and ecological footprint. Therefore, under this approach, the fishing activity is sustainable along the coast of Jalisco.

Sustainable fishing includes how fishermen live. We describe the quality of life (QOL) and lived experiences (LE) of fishermen along the coast of Jalisco, whose average daily income is slightly above the poverty level. The relationships among income, size of catch and QOL are explored using data collected in 2012 from a sample of 83 fishermen. QOL included indicators like health, income, cost of living, family, friends, holidays, education and future perspective. The QOL index combines importance and achievement ratings scores, the results are indicative of an acceptable QOL for fishermen. The concept of LE is elaborated and interviews conducted with a sample of 13 fishermen. A graphical representation of four dimensions of LE comprising aspects of life relating to Mind, Body, Work and People for each fisherman is derived, where each person was asked on the importance and gaps between aspiration and actual situation about each dimension. We found that the most important dimension in a fisherman's life is People. The gaps identified suggest that the significant gaps that should be closed, were associated to the Mind dimension, then Work and Body, and finally People. Concerning the responsibility for closing gaps, respondents identified four options ordered by frequency: self, government, self with the help of family members, and God/ faith. An inverse moderately strong relationship between catch, marginalization and QOL score was found, while income and QOL score were directly related. In general, future and past are not better than the present. All these and LE are discussed in the sustainability context
