I. A.3 DEMERSAL FISHERY RESOURCES SURVEY, ASSESSMENT AND MONTORING ALONG SOUTH- WEST COAST, WADGE BANK AND GULF OF MANNAR BETWEEN Lat. 07°N – 12°N

Project Co-coordinator

Dr. Sijo P. Varghese, Zonal Director

Project Components

• Demersal fin fish resources survey in the South-West coast, Quilon Bank, Wedge Bank and Gulf of Mannar between 7°N and 12°N in 100-500m depth.
• Monitoring of demersal resources using fish trawl in 30-100m depth
• Exploration and species inventory on slope dwelling resources in 200-500m depth

Period: April 2021 – March 2022

Project Objectives

• Preparation of species inventory of demersal fin-fish and shellfish resources.
• Estimation of abundance indices of demersal resources and the major components thereof, with emphasis on scads, lizard fish, threadfin breams, squids, cuttlefish , bulls eye, crabs, carangids and horse mackerel
• Mapping spatio – temporal distribution pattern of the resources
• Study of biological aspects of selected 10 important species
• Investigation of biology of perches in Quilon Bank, Wadge Bank and Gulf of Mannar.
• Imparting training in fishing techniques and demonstrations of modern equipment on board to the fishermen, fishing industry representatives and entrepreneurs.
