Abstract

Shrimp seed of five commercially important penaeid species viz., Fenneropenaeus indicus, Fenneropenaeus merguiensis,
Peneaus monodon, Metapenaeus monoceros and Metapenaeus dobsoni were encountered in the Mulki Estuary during the
present investigation. F. indicus was predominant in the samples in the early pre-monsoon period (25 to 28.3%) and late
post-monsoon period (18.2 to 21.4%) at all the stations. F. merguiensis seed showed distinct variations and was dominant
during pre-monsoon months (30 to 89.3%) whereas P. monodon seed was predominant during early pre-monsoon season
(22.1 to 26.6%) at all the stations. Both M. dobsoni and M. monoceros were dominant during the later part of post-monsoon
season (22.1 to 26.6%; 9.8 to 47.6% respectively). Among the hydrographical parameters tested salinity (r = 0.6954) and
temperature (r = 0.7307) showed significant positive correlation with shrimp seed availability in the Mulki Estuary.
