Application of remote sensing techniques forudlocating pelagic fish concentrations along theudKerala coast (SW coast of India) - work done andudfuture prospects

摘要

Intensive validation programme on Potential Fishing Zone forecastsudcarried out by the MARSIS, Central Marine Fisheries ResearchudInstitute, Cochin, at 17 selectedjish landing centres along the Keralaudcoast between November 1995 and May 1996 revealed a positiveudrelationship betwen PFZ and occurence/abundance of commerciallyudimportant pelagic fishes. An attempt is made to identify possibleudreasons for the above, based on results of oceanographic itivestigationsudundertaken in the area and also taking into considerationudfish behaviour in relation to environn-ieni based on past data. Futureudplans for evolving a suitable prediction system for commerciallyudimportant pelagic fishes in the coastal waters of the mainlandudand skipjack fishery in the Lakshadweep islands based onudPFZ forecasts are also discussed in view of its importance to theudartisanal and small mechanised sector fishermen for reducing theudsearching time and thereby effecting an overall reduction in the costudof fishing.
