Abstract
The spatial and temporal distributions of larval prawns of penaeids and non-penaeids
in the estuarine waters of Mangalore were studied. Larvae appears to be passively
brought in by the incoming flood tides to the estuary, enjoy a wider distribution throughout
the estuarine complex with abundance towards the mouth. The distribution of
larval prawns were more in Nethravati than in the Gurupur stretch. The influence of
temperature, hydrogen-ion-concentration, salinity and dissolved oxygen on the distributtion
of larvae in the estuaries is discussed. Inference on spawning seasons of commercially
important prawns in the neighbouring waters has been arrived at based on their
larval abundance
