  • The Atal Centre for Ocean Science and Technology for Islands (ACOSTI) of the National Institute of Ocean Technology (NIOT) of Chennai, has launched a new sub-sea feeder system to provide feed inside open sea fish cages.
  • It has also launched a system to monitor the health of fish.
  • These systems were recently launched at the Andaman and Nicobar Islands.
  • These are aligned with the national goals under the Deep Ocean Mission and the vision for an inclusive blue economy.
  • Since these cages are parked at depth of 7 m to 10 m, a water ejector based sub-sea feeder has been developed by NIOT to safely convey fish feed.
  • This design not only enhances the feeding process but also significantly reduces energy consumption since it is powered by a floating solar power system.
  • The National Institute of Ocean Technology (NIOT) was established in November 1993 as an autonomous society under the Ministry of Earth Sciences.
  • The institute is based in Chennai.
