Project Title:

Evidence-Based Conservation of Critically Endangered Guitarfish in Coastal India

Project Brief:

The wide-nose and sharp-nose guitarfish are both Critically Endangered and extremely understudied rhino rays. They occupy shallow coastal waters, making them vulnerable to human activities and threats. Building on previous research, which identified important aggregation sites and potential nursery grounds of juvenile guitarfish in South Goa, this project will assess guitarfish abundance and identify their critical habitats across two states along India’s east and west coasts. The team will use walking transect surveys—developed during the earlier phases of their work—and adapt them to different conditions to develop a simple, low-cost method to monitor guitarfish.

A long-term monitoring system, with local stakeholders, will be set up in Goa—the first of its kind in India—to continue monitoring guitarfish beyond this project’s duration. This will help understand population trends over time, especially in nursery grounds crucial for the species’ conservation. In Tamil Nadu, outreach programmes with relevant stakeholders, including education programmes in schools, will be implemented to increase awareness and build positive attitudes towards guitarfish and ocean conservation. Conservation interventions will be co-created with local communities, building on successful models from their previous work, to promote conservation and the live release of guitarfish caught as bycatch.

Project objectives:

The project has the following objectives:

  • Identify and monitor nearshore critical habitats of guitarfish within Goa and Tamil Nadu.
  • Assess guitarfish abundance and seasonal variation at potential critical habitats.
  • Set up a long-term monitoring system at Goa in partnership with the Forest Department and local communities.
  • Promote awareness, develop live release programmes among local fishers, and implement education programmes for children.
Project Location:
  • Goa & Tamil Nadu
