Project Coordinator
Shri D. Bhami Reddy, Mechanical Marine Engineer
Project Components
- Exploratory survey of demersal resources using 34mFish Trawl in 100 – 200m depth.
- Monitoring of demersal resources using 34m Fish Trawl in 30 – 100m depth.
- Exploratory survey using 34m Shrimp Trawl in 30 – 500m depth.
- Experiments for assessment of fishing gear efficiency.
- Mesh selectivity study with cod end cover.
Period : April 2021 – March 2022
Survey and Research Objectives
- Preparation of species inventory of demersal fishery resources.
- Estimation of abundance index of demersal fishery resources and the major components thereof, with emphasis on threadfin bream, catfish, mackerel, scads, goatfishes, perches, Silverbellies, bullseye and croakers.
- Identifying spatio-temporal distribution pattern of the resources.
- Study of biological parameters of important species.
- Stock assessment of important resources.
- Imparting training in fishing techniques and demonstrations of modern equipments on board to the fishermen, fishing industry representative and entrepreneurs.
