Significant Achievements in the last 5 years
- Prediction and modelling of marine fishery yields from Arabian Sea off Karnataka using ECOSIM
- Strengthened the scientific database -catch and effort of the exploited fish stocks and their distribution, abundance, biological characteristics, mortality rates, yield per recruit, status of exploitation, sustainable yield and techno-economics of fishing operations.
- The effect of bottom trawling on the benthic fauna off Mangalore coast was studied and reported
- Log sheets in local languages prepared and distributed to sampled commercial fishing crafts to collect in-situ data on fishing operations, catch and effort.
- Participatory GIS program (PGIS) in marine fisheries for spatio-temporal resource mapping to avoid resource damage, identify seasonal juvenile abundance and evolve management strategies for conservation and sustainable harvesting
- Innovative GIS based methodology developed for resource mapping of marine fishes to reduce CO2 emission from Trawlers.
- Purse-seining with light popularized through fishing demonstrations off Karnataka coast
- Advisories cautioning the impact of this destructive fishing method were provided to the State administration
- Limit reference points (LRP),YMSY & fMSY and target reference point (TRP), f0.1, were set for cephalopod resources (Karnataka) to guide rational fisheries management decision.
- Inter-cohort growth pattern of cuttlefish, Sepia pharaonis population (Clade C), distributed along the Eastern Arabian Sea (South-West coast of India) modelled.
- Protocols for age estimation in Indian squid Uroteuthis (Photololigo) duvauceli using hard-parts standardised.
- Protocol for tagging large sized yellowfin tunas with pop-up satellite tags was standardized.
