Prevalence and abundance of pharmaceutically important fungi in P. monodon culture ponds of two culture periods (2008-2009) were investigated. Studies on the kinds and dynamics of fungi related with Penaeus monodon culture system have revealed the presence of 17 species associated with post larvae, food sources, shrimp culture pond water, sediment and sea water sediments. Eleven types of fungi were isolated from microencapsulated feed, live feed Artemia nauplii, Monodon baculovirus (MBV) infected and uninfected post larvae and post larval rearing water in 5 different hatcheries located at East coast of India. The fungi with biomedical potentials such as Aspergillus spp., Rhizopus spp., Trichoderma spp., Cladosporium spp., Microsporum spp. and Mucor spp. were more prevalent in water and sediment samples from shrimp culture system and source seawater area. Species of Aspergillus, Curvularia spp., Drechslera spp. were more abundant in feed samples. The species of Aspergillus were more dominant in almost all samples collected from shrimp culture hatcheries and pond, Fusarium spp. and Lagenidium spp. which are the potential pathogens of shrimp were not observed throughout the period of study. The fungi isolated from present study have enormous potential in pharmaceutical industries and biological activities of fungi isolates were discussed in detail.
