Abstract A few physical parameters and processes correlated with sardine landing
could not establish a flawless connection, and explain the phenomena of inter-annual variability.
Earlier researchers indicated that the probable appearance and disappearance of sardine is an active
movement in search of food and congenial conditions. But, no specific study has been carried out to
explain the variability of sardine catch based on chlorophyll availability on a synoptic scale. An
attempt is made in this study to correlate variability in chlorophyll-a with sardine landings along the
waters of southwest coast of India. We have estimated monthly averaged surface phytoplankton
biomass along the waters of southwest coast of India from the shoreline upto 200 m isobath for ten
years from SeaWiFS ocean colour data. This estimation is compared with the biological calendar of
Indian oil sardine. The average chlorophyll-a for the bloom initiation month (1998-2006) matches
very well with oil sardine landings. The results imply that the concentration of chlorophyll during the
bloom initiation month can be used to assess the quantum of fish that recruit into the population.
Finer scale spatial variations in the chlorophyll along the coastal waters help in deciphering the
migratory pattern of sardine during their active breeding phase
