MULTIDISCIPLINARY APPROACH TO IDENTIFICATION OF FISHERY SYSTEMS IN AMAZONIAN RESERVOIR: CASE STUDY IN TUCURUI DAM

Dams cause profound changes in the structure of environments and local fishing practices. One example of these impacts is the Tucurui dam, in the southeast of the state of Para, in northern Brazil. The changes were gradual, but eventually established unique fishery systems and capture techniques that were consolidated over time. The present study used a rapid analysis technique based on the Metier principle to identify 14 fishing systems with distinct characteristics, although a more holistic approach (dimensions: economic, social, technological, and management), supported the identification of four clearly distinguishable groups. From the management perspective, studies of this type are important because they permit the establishment of more effective practices based on the deficiencies found in the different systems or their respective groups.

Automated summary

Dams have significant impacts on the environment and local fishing practices, leading to the development of unique fishery systems and techniques. Using the Metier principle and a holistic approach, this study identified 14 fishing systems with distinct characteristics and four clearly distinguishable groups. Such studies are essential for establishing more effective practices based on the deficiencies found in different systems or groups.
