Abstract(s)
The Tagus estuary, in Portugal, with about 320 km2, is one of the largest estuaries in Europe, thus, several
fishing communities dedicated to octopus’ fisheries can be found in it. For the first time, a comprehensive
study was done with report to all the vessels triangulated with the answers of all fishermen, which allows
us to know the exact quantity captured in the estuary. For this purpose, in 2018, data from all vessels
were collected and all the fishermen were interviewed. In this study, the different types of fishing gears
employed are described, as well as the purpose and the procedures of their construction. On the other
hand, the real volume of captures in the estuary and the fishing efforts were thoroughly calculated.
Furthermore, the main problems reported in this activity were: environmental damages, legal issues,
usages and the relationship between all the intervenients in the process. In the end, several changes were
proposed in the management of sustainable octopus’ fisheries in this area, which can be replicated to
other areas.
