Recent years have a witnessed a growing interest in the use of limno-chemical for water status. Incorporated in the most important laws concerning water management, different key components: hydro-morphological aspects (particularly habitat structures, flow regime, connectivity), physico-chemical parameters, macroinvertebrate and fish assemblages/ potential, biological water quality assessment and ecotoxicological evaluation, depicted potency of water. Studies on phytoplankton primary production in running Ganga water resources during 2013-14 and 2014-2015 revealed that both the gross and net primary productions were more (660.02 and 414.36 gC/m2/y) in the first year as compared to second (569.82 and 353.04 gC/m2/y) year primarily because of favorable climatic and edaphic conditions coupled with more inflow and less outflow in the first year. Community respiration was not varied widely (251.14 and 214.72 gC/m2/y) in the two years respectively. Primary production showed high correlation with specific conductance, total alkalinity, Chloride, TDS, BOD and total hardness. Potential fish yield was 80 kg/ha/y against the present harvest at 20 kg/ha/y leaving enough scope of augmenting fish production through sustainable management practices.
