Description Dynamics of penaeid postlarval ingression and settlement the backwaters of Cochin were
studied. Postlarval recruits were constituted by Metapenaeus dobsoni(70.8-78.40%)Penaeus
indicus (7 .5-24.6%), M. rnonoceros (3.8-4.6%) and P. monodon (0.3-0.4'%). Their
composition varied with location and season. Postlarval abundance and ingression were
influenced by diel, tidal, lunar and seasonal factors. Ingression is mainly nocturnal in all
species with nearly 84% of the activity during night hours. Abundance and ingression
peaked up during high tides at night with major peaks coinciding with spring rides of full
and new moon. It also followed a generalized seasonal pattern with two well-defined peaks
for all species. It was pre-monsoon followed by post-monsoon for P. indicus and M. momoceros
and postmonsoon followed by pre-monsoon for M. dobsoni. Slze of the recruits
were relatively small during pre-monsoon and post-monsoon and large during monsoon
