Human dimensions of bycatch in small-scale shrimp trawl fisheries: implications for bycatch reduction devices in southern Brazil

Bycatch in shrimp trawl fisheries is a recognized issue tackled with technological modifications such as Bycatch Reduction Devices (BRDs) aiming to improve gear selectivity. Bycatch also represents an important source of livelihood diversification in small-scale shrimp fisheries, enhancing food security and income. Therefore, an integrated understanding of the local socio-ecological context is required for an effective implementation of BRDs. I evaluated the effect of socio-economic dimensions and fishers’ attitudes on the acceptance of BRDs at the Protected Area of Anhatomirim (Santa Catarina state, South Brazil). Data was collected through participant observation, semi-structured interviews and workshops; secondary data about previous demonstrative experiments with BRDs was also used. Loss of valuable bycatch and link to the management system constrain willingness to use BRDs, enhancing the need for local adaptation of BRDs through a cooperative process. It was observed that beyond a technological modification, an integrated and participative approach to BRDs generates insights into alternative management strategies involving fishers’ collaboration.
