Abstract
Physico-chemical characteristics of water and plankton were analysed from four paddy fields, irrigated by a tributary of the river Ravi, near Nagri bus stand, Kathua, J&K, during July, 2005 to September, 2005 have been described. Phytoplankton has shown the presence of Chlorophyceae (14 genera), Bacillariophyceae (9 genera) and Cyanophyceae (6 genera). The order of qualitative dominance of zooplankton is observed as Protozoa (10 genera and 31 species) > Rotifera (8 genera and 9 species) > Arthropoda (8 genera, 8 species and 3 larvae) > Annelida (1 genus and I species) and> Nematoda. Planktonic diversity and density remained low during first two observations (preparation of fields and seedlings transplantation). Coefficient of correlation (r) of phytoplankton and zooplankton, with the various parameters of water, is insignificant.
