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
