Description	Not Available 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 Not Available
