Rajagopalan, M and Girijavallabhan, K G and Bharathan, Geetha and Kathirvel, M and Nammalwar, P and Dhandapani, T (1985) An instance of mass mortality in the Muttukadu farm near Madras during April 1983. Marine Fisheries Information Service, Technical and Extension Series, 61. pp. 8-12.
An unusual mortality of fishes and other organisms was observed in the open site surrounding the farm at Mariculture Centre of CMFRI, Muttukadu.at 1983. During this season the prevailing high temperature and salinity and the enclosed nature of the water body, all resulted in an intense bloom of dinophytes. This led to oxygen depletion of the waters and then, very likely, of the mud. The regular operation of drag nets and gill nets has stirred up the mud and created large scale disturbance which, combined with the oxygen depletion, must have precipitated the crisis and led to the mortality of prawns and fishes.
