Diversity of Ornamental Fishes in Lower Manair Dam at Karimnagar Dt. Andhra Pradesh.

Abstract

The present investigation concerns with the aquatic macrophyte diversity and its role in understanding the reservoir ecosystem dynamics and species composition of aquatic macrophytes distribution in ten villages around Lower Manair Dam (LMD) were studied during 2013-2014. Forty eight different species of aquatic macrophytes were recorded in 04 classes, 20 orders and 26 families, which include five free floating macrophytes, ten submerged, and thirty three emergent species of weds were recorded. The percentage composition of class, order and families were calculated during this period. The free floating species Eichornia crassipes occurs throughout the year, while the submerged species Vallisneria spiralis, Ceratophyllum demursum, Hydrilla verticillata occur throughout the year. In the rooted floating category Ipomoea aquatica occurs throughout the year. The common name, habitat and IUCN (2013.2) status of the macrophytes has also been noted in the present paper.
