ABSTRACT
Aquatic macrophytes are vascular
plants whose photosynthetic parts are permanently or at least for several
months of the year are submerged in water or float on the surface of
water. Aquatic macrophtyes that grow unabatedly
causing harm to aquatic environment directly or to related eco environment
relatively, are called aquatic weeds. Invasive aquatic plants are those that
displace native aquatic vegetation and become established.
Invasive aquatic
weeds are threatening the ecological, sociological, cultural and economic well
being of the local people residing on those areas. The effectiveness and
efficient control of the invasive is premised on knowing these aspects of the
biology and ecology of this aquatic weed. This paper therefore reviews these
environmental factors: temperature, light, dissolve gases, pH, nutrient,
salinity substrate, water and competition that effect the proliferation of
aquatic weeds.
