Overview:

Centro de Estudos Costeiros - Universidade Eduardo Mondlane (UEM-CECU) successfully implemented the CrabWise project, boosting the artisanal mud crab fishery in the Bons Sinais Estuary, Mozambique, through a community-based restocking program using hatchery-reared crablets.   

The Challenge:

The mud crab fishery in the Bons Sinais Estuary faced sustainability challenges due to overfishing, habitat degradation, and limited community participation in resource management.

The Solution:

The project established a mud crab hatchery and released 1,000 hatchery-reared crablets into the estuary to enhance wild populations. It also conducted ecologic assessments on population, food habitats and habitat  and established a monitoring program to assess the restocking impact.   

Why this Matters:

This initiative not only improved the sustainability of the mud crab fishery but also the model of hatchery based juveniles is also being showcased by management authorities  as the only solution to address a sustainable aquaculture of this resource in the near future in Mozambique. 

Main Outputs and Achievements:

The project successfully established a mud crab hatchery and released 1,000 hatchery-reared crablets into the estuary. It also trained 35 community members, including 15 women, in crab monitoring techniques and sustainable fishing practices.   

Support the Project: 

Potential partners can support UEM-CECU by providing funding for scaling up hatchery operations, acquiring additional monitoring equipment, supporting disease monitoring, funding larval feed, expanding community training programs, and supporting research on mud crab ecology and restocking strategies.

Lessons Learned:

The project underscored the need for ongoing research to optimize mud crab cultivation, including survival rates, environmental conditions, and dietary preferences, as well as robust monitoring and evaluation to assess the effectiveness of interventions. It also emphasized the critical role of community engagement, capacity building, and adaptive management in implementing effective restocking programs.
