Chlorophyll is used as a proxy for measuring the phyto- plankton biomass.
An integrated optical system capable of detecting and monitoring algal (or phytoplankton) blooms both spatially and temporally in coastal and open ocean waters has been developed by a team of researchers at the Indian Institute of Technology (IIT), Madras. Very soon, the Hyderabad-based Indian National Centre for Ocean Information Services (INCOIS) will begin using the optical system for detecting and monitoring algal blooms in ocean waters surrounding India. INCOIS is currently in the process of making the system operational.
Phytoplankton are the base of the aquatic food web, providing food and shelter for different organisms including fish. Along with other parameters, phytoplankton biomass (algal blooms) tends to behave as potential zones of fish aggregation......................Read more
