Gillnets are the most important indigenous fishing gear operates in inland and marine waters. This paper deals with design and general features of large mesh marine bottom set gillnets called Thirandi Valai or Thirukku valai targeting rays operated in Kanyakumari coast of Tamil Nadu. The gillnet is having a mesh size of 450 mm and is made of High Density Polyethylene (HDPE) of 2 mm dia. If not monitored properly the targeted fishing with this net may lead to overfishing of ray species.
