Heterotrophic bacterial activity in selected aquaculture systems near Cochin

Thirumani, S Santhi (1992) Heterotrophic bacterial activity in selected aquaculture systems near Cochin. PhD thesis, Central Marine Fisheries Research Institute. Submitted to Cochin University of Science and Technology.



The interplay between production, consumption and decomposition a r e t h e three important eco-regulatory and balancing process in aquaculture ponds which determine and ' regulate the output levels. Various microbial communities a r e involved in each of these ecological processes and their activities constitute the basis of trophic interactions. By regeneration and transformation of nutrients bacteria form the first link connecting the live organisms with the abiotic factors. However, the pond fertilisation practices have been so far based largely on the chemical factors and plankton levels. Only in recent years microbiological investigations with reference to aquaculture productivity and heterotrophic activity have been initiated, and the present work gives an account on the influence of hydrological parameters on heterotrophic activity in seasonal and perennial ponds of Narakkal, Cochin.
