Contribution of the CORECRABE action-research project to science-support management

The session is introduced by a 10’ video on the context and the wicked
problems in mud crab fisheries in Madagascar and the work undertaken to
address them since 2019 as part of the CORECRABE European action-research
project (http://corecrabe.ird.fr/). Based on their own experience, the first and
second speakers will then explain (10’ each) the role and interest of the fishery
sector and the national network of women in fisheries in Madagascar
(RENAFEP), respectively, in participating in both the fishery monitoring and
the discussion process through the four regional multi-stakeholder working
groups that were established by the project. The following speaker (10’) will
describe the participative and collaborative information system that has been
deployed since 2021 to address recurrent data-deficiency issues, build
technical and scientific capacities, and provide accurate fishery indicators
(e.g., size structure, fisher census, catch per unit of effort) to the working
groups. As part of the blue justice agenda in small-scale fisheries, the 4th
speaker (10’) will present the market-driven mechanisms that have driven
fishing effort throughout the value chain and how these mechanisms may be
affected by fishery governance and export rights. the 5th presentation (10’)
will further analysis those mechanisms through an empirical bioeconomic
model for predicting the impacts of the local purchase price (i.e., « vessel price
») of mud crab on the stock dynamics and the fishers’ socioeconomic benefits.
The final speaker will broaden the scope of both the research and action by
highlighting users’ rights in the mangroves and mapping mud crab fishing
patterns. A short conclusion will highlight the main lessons learnt from that
transdisciplinary action research approach that may inform other research-
based interventions in small-scale fisheries and contribute to the
implementation of the SSF Guidelines in African countries.
