Abstract
Trichodesmium erythraeum is a filamentous cyanobacteria which forms dense algal bloom along the Pudhumadam coast in the Gulf of Mannar during the pre monsoon season 14th September, 2014. At the time of bloom totally 25 zooplankton species were observed of which four species were considered as most abundant viz. Corycaeus danae (19.28 %), Acrocalanus gracilis and Microsetella norvegica (7.23%) and Gastropod veliger (6.02%). Although the T. erythraeum occurred in high concentration (75,000/m3), it did not cause any unusual mortality to the marine large fish and shellfish and disrupt the marine environment.
