The annual exploitable fisheries of Andaman and
Nicobar Islands are estimated to be 1.48 lakh t of
which a meagre 22% is harvested currently. Potential
Fishing Zone (PFZ) forecasts based on remotelysensed
chlorophyll concentration and sea surface
temperature were applied for harvesting the
unexploited marine fishery resources. Simultaneous
validation experiments (n = 87) synchronizing with
PFZ forecasts within (PFZs) and outside (non-PFZs)
the demarcated zones employing different vessel
categories viz., gillnetters (n = 50), trawlers (n = 22)
and longliners (n = 15) were carried out. Significant
disparity in fish catch was observed within and
outside PFZs. Fish catch from gillnetters composed
of carangids, clupeids, scombrids with Megalaspis
cordyla being dominant at PFZ. Carangids,
sphyraenids, serranids, lutjanids, lethrinids and
carcharhinids were reported from trawlers with
significantly higher CPUE from PFZs except
nemipterids. Fish catch from longliners constituted
mainly of carcharhinids and serranids, where the
catch of former was found to be significantly higher
at PFZs.
