Water sampling methods and determination of some physico-chemical parameters of aquatic habitats shall be dealt with; sampling and enumeration of plankton and plankton productivity, using the “light and dark” bottle method, chlorophyll-a concentration and biomass estimates will be studied. Sampling of benthos and determination of productivity of benthic faunal populations using the removal-summation, instantaneous growth, Allen curve, and Hynes methods will be studied. Analysis of substrate particle size would also be carried out.
