Concentration of cadmium, copper, lead and zinc in thirty five genera of freshwater microinvertebrates from the Fox River, Illinois and Wisconsin. National Symposium on Biodiversity, Biotechnology and Environmental Toxicology in the New Millennium held at Mumbai, India on 22nd to 24th November 2004, 85 pp.Īnderson, R. Biochemical changes in the liver of Channa punctatus after chronic zinc exposure. The study suggests that all the six collection sites are polluted and the red worms contaminated with heavy metals and hence, unfit for use in aquaria or feeding any variety of fish or crustaceans in the hatcheries.Īgrawal, M., & Srivastava, N. Data revealed the presence of heavy metals in water and sediments at collection sites and bioaccumulation of cadmium, iron, lead, zinc and copper in body tissues of Tubifex worms. Six natural red worm ( Tubifex spp.) collection centres in Mumbai and Thane districts of Maharashtra state in India constituting a major source of live Tubifex supply to aquarium fish industry were evaluated for pollution, heavy metal concentration in water, sediments and in the body tissues of Tubifex. Reports of morbidity and mortality from aquarium fish culturists in and around Mumbai led to the present investigations on the ecology of these habitats with a view to assess the water quality, presence of heavy metals in the environment and their bioaccumulation in Tubifex worms, and to examine whether these habitats could be exploited to meet the demand of the industry. These habitats receive domestic sewage and industrial wastes from nearby residential and industrial areas.

Live feeds, especially Tubifex spp., which are collected from a wide variety of polluted habitats, are used by aquarium fish keepers in India.
