The distribution of penaeid prawns in Ceylon waters

Thirty one species of penaeid prawns have been discovered in Ceylon waters. A taxonomic study of these species was carried out and their distribution in relation to hypothetical oceanographical barriers was discussed (De Bruin 1965.) As penaeid prawns are of important commercial value, a study was made of their distribution and relative abundance in the estuaries and seas round the island. The results of this study are reported in this publication.
