Notes

  • INCOIS (Indian National Centre for Ocean Information Services) launched the Hilsa Fishery Advisory (HiFA) to assist fishermen in locating favourable fishing grounds.
  • HiFA utilizes machine learning algorithms to provide a three-day outlook on Hilsa availability, categorised into five levels: very low, low, medium, high, and very high.
  • The advisory integrates satellite observations, numerical ocean models, and fisheries science to identify potential fishing zones.
  • Hilsa migration and aggregation are influenced by environmental factors such as salinity gradients and productivity caused by monsoon rainfall and river discharge into the Bay of Bengal.
  • Ocean currents play a critical role in shaping pathways for Hilsa movement between marine and estuarine ecosystems.
  • On August 11, fishermen near Digha, West Bengal, recorded a haul of 30-40 tonnes of Hilsa, validating the predictive accuracy of the HiFA system.
  • Data-driven advisories help reduce fuel consumption and time spent searching for fish by providing actionable information based on environmental signals.
