J.K.P. Edward, K. Ayyakkannu

Abstract



Secondary production of Tellina nobilis and T. cuspis from Coleroon Estuary (Lat. 11 degrees 21'N; Long. 79 degrees 50'E), Southeast Coast of India was investigated between January and December, 1986. The annual secondary production for T. nobilis was 5.8553 g/m super(2) and for T. cuspis 2.2651 g/m super(2). The biomass (B) was 5.5281 g/m super(2) for the former and 3.06 g/m super(2) for the latter. The P/B ratio was 1.0592 and 0.7402 for T. nobilis and T. cuspis respectively
