Red snapper fishing (Lutjanus purpureus) is an important fishing activity for the Brazilian economy due to its export. The scarcity of up-to-date information on this system's ecology, economy, and social characteristics contributes to inefficient management. We analyze whether the commercial snapper fishery on the Amazon continental shelf is socioecologically sustainable.

This is particularly the case when baseline data on a vulnerable stock are poor, as the integration of fishers' experiential knowledge can help fill data gaps, as well as inform legitimate management actions, and empower fishing communities in resource management. This study aimed to analyze fishers' knowledge regarding the biology (reproduction, growth, and maximum size) and temporal changes in the abundance and size of six commercially important marine species (red porgy , veined squid , blue jack mackerel , blackspot seabream , blackbelly rosefish , and European conger ) in the Azores small-scale communities.

Therefore, it is necessary to generate biologically and ecologically based fishing plans to make this fishery sustainable over time. The silver scabbardfish, , is a worldwide-distributed demersal fish, commercially exploited in the Azores.

Despite its economic and ecological importance, limited information is available to perform stock assessments and make robust management decisions. In this study, demographics and exploitation levels of were determined from coastal areas of the Azores, and the relevance of these data for conservation planning was discussed.
