Description In the atolls of Lakshadweep, juveniles of Acanthuridae and Labridae were
most abundant on seagrass beds, the former during pre-monsoon and postmonsoon
periods and the latter in pre-monsoon. Schooling species showed variable
recruitment. Non-schooling species were rare. Peak settlement was observed
during pre-monsoon and post-monsoon seasons. Continuous occurrence
of juveniles in different size ranges confirms the continuous spawning habits.
Chaetodontids and holocentrids occurred consistently round the year.
Seasonality in occurrence was most pronounced in Carangidae and Siganidae,
but not so in Apogonidae, Lutjanidae and Mullidae. Seasonal abundance of
juveniles was influenced by summer peaks, timing and magnitude of settlement,
adult spawning and local migrations. Abundance of larvae increased
with salinity. Juvenile abundance, independent of environmental parameters
seemed to be controlled by seasons, tides and currents. Lunar phases and abundance
of juveniles were found to be co-related.
