Effect of Nitrite on Oxygen Consumption and Ammonia Excretion of the Fresh Water Crab Paratelphusa jacquemontii (Rathbun)
Abstract: In aquatic ecosystem, nitrite concentrations are elevated by pollution with nitrogenous wastes and imbalances in bacterial nitrification and denitrification processes. Nitrite is transformed by nitrification to nitrate under aerobic condition. The effects of nitrite on physiology were investigated in the fresh water crab, Paratelphusa jacquemontii (carapace length 4–5 cm and weight 50–70 g) for 96 h. The crabs were exposed to sublethal concentration (1/10th and 1/20th of 96 h LC50) …

Impact of Mercuric Iodide on the Growth of Phormidium spp.
Abstract: Cyanobacteria are microalgae which are freely distributed in aquatic environment. They are photosynthetic organisms and can fix atmospheric nitrogen under anerobic condition. Such cyanobacteria have been applied as a nitrogen fertilizer in agriculture to improve the crop yield. Since the application of chemical fertilizers in crop fields created heavy metal pollution which could be neutralized by microalgae under aquatic environment. They have ability to tolerate the heavy metal concentrations under …

Phytoremediation of Aquaculture Wastewater: Duckweed (Lemna minor L.) as a Phytoremediator
Abstract: Aquaculture systems discharge huge quantities of waste into the aquatic ecosystem, in the form of excretory products and excess feed. These have grave implications on physicochemical and biological quality of the receiving environment. The study aimed to determine potential of duckweed (Lemna minor L.) for phytoremediation of aquaculture effluent. Hundred grams (100 g) of duckweed was grown in 10 L aquaculture effluent for 7-, 14-, 21-, and 28-day retention period …
