Starting from a global perspective of the current state of exploitation of fishery resources, we enter into those aspects that have not yet or have been poorly incorporated in the management of fisheries. The changes in climate patterns are one of the essential aspects, and separating the effects on stock abundance due to fishing from those caused by the impact of change in climate patterns is essential to gain precision in estimates of fishing mortality, and to identify proper biological measures to favor sustainability. The need to recognize the dynamic complexity associated with the biological hierarchies of which the exploited stocks are part is also highlighted: the individuals, the populations, and the ecosystems. Each natural entity has its own dynamics and performance; they interact with each other, are interdependent, and nested within each other. In this context, the effects of changes in climate patterns affect the hierarchical levels in different ways, which also respond, each, in a particular way, and in a scenario of continuous change with trend, management decisions must involve the different key processes of the different biological hierarchies. To exemplify these concepts, some processes observed in the Bank of Campeche, in the southern of the Gulf of Mexico, are shown.
