g chlorophyll (Chl)a l^-1] and primary production (507.9-571.2 &mgr;g C h^-1l^-1), comparable with some of the highest values reported. There were contrasting changes in the carbon assimilation ratios, composition of the phytoplankton and the contribution of nanoplankton (<20 &mgr;m) between 11 and 12 May. On 11 May, carbon assimilation by nanoplankton was 2.2 &mgr;g C (&mgr;g Chl a)^-1 h^-1, but increased to 9.2 &mgr;g C (&mgr;g C (&mgr;g Chl a)^-1 h^-1 the following day. Nanoplankton contributed 56 and 9% of Chl a and production, respectively, on 11 May, while net plankton (>20 &mgr;m) accounted for >65% of the biomass and primary production on 12 May. Picoplankton (<3&mgr;m) contributed <8% of Chl a and<3% of production. Frequent sampling will be necessary to capture such dynamic changes and ephemeral events in these waters.23:T422,Ten species of echinoderms viz. Holothuria atra, H. scabra, Bahadschia marmorata, Actinocucumls \ntyphus, Pentoceraster regulus, Tropiometra carinata, Astropecten indiciis, Goniodiscaster scaber and \nStomopnemtes variolaris have been screened for the biotoxicity of their various organs. Four series of \nbioassays were carried out. They were tested for toxicity to Chanos and Tilapia fingerlings, toxicity \nto mice and hemolytic activity. The gradation strongest to weakest toxic species is H. atra (both body \nwall and viscera), B. marmorata (both body wall and cuvierian tubules), H. spinifera (both body wall \nand viscera), H. scabra (body wall alone), P. regulus (body wall alone), A. typicus (body wall a lone), A. \nindicus, H. scabra (viscera), P. regulus (viscera), S. variolaris (viscera), G. scaber, T. carinata and A. \ntypicus. Further detailed analysis is being pursued on isolation aod characterisation in order to determine \nthe variation In toxicity and the causative factor responsible for the same.
