Karthikeyan by introducing it to All Kerala Fishing Boat Operators Association president Peter Mathias. The app was developed by the National Informatics Centre for the Fisheries Department. Functional on versions from android 4.4, Sagara can be downloaded from google play store. Since there are still chances for climate change-triggered natural calamities, fishermen should make use of safety measures, said the Collector. The app is available in Malayalam, English and Tamil. Boat owners and their representatives can use the app by entering the route and list of persons on board.
