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) …

Effect of Short-term Exposure of Agrochemical Constituents (Nitrate, Nitrite, Phosphate and Potassium) on Survival of Fingerlings of Guppy Fish, Poecilia reticulata
Abstract: Increased use of agrochemicals enhances eutrophication and thereby inducing hypoxic condition which adversely affects aquatic flora and fauna. Present study was aimed to investigate the effects of short-term exposure of different concentration of nitrate (NO3), nitrite (NO2), phosphate (PO4) and potassium (K) on survival of Guppy fish, Poecilia reticulata. Fingerlings of Poecilia reticulata were exposed to increasing concentration (1, 10, 100, 1,000 and 10,000 mg/L) of NO3, NO2, PO4 andK …

Review of Nitrite Inhibitor for Protection of Rebar Corrosion
Abstract: Load bearing concrete structures need steel reinforcement (rebar) strips or rods, which are prone to attack by the corrosive environment inside the concrete due to constant ingress of moisture, pollutant gases and anions (mainly Cl-, SO4- -). One of the means of reducing such type of corrosion is the use of inhibitors. Inhibitors are water soluble but film forming on metals by their selective adsorption on the metal surface. These …

Growth and Nitrogen (N) Metabolizing Enzymes of Mesophilic and Psychrophilic Heterocystous Cyanobacteria—In Response to Temperature Regimes
Abstract: The increased NR & NiR activity, GS and nitrogenase activities at 25°C and 35°C in psychrophilic and mesophilic organisms indicates that the Arctic isolate is a psychrotolerant as it shows increased enzyme levels than its original temperature in which we isolated the organism though biomass was greater at 3°C. The biomass and enzyme data indicates cyanobacteria are the initiators of primary colonization in polar and alpine environments and are responsible …

Nitrosamine Accumulation, Processing Variables, and Indigenous Plant Inhibitors in Nigerian Traditionally Processed Meats
Abstract: N-nitrosamines are classified as probable or possible human carcinogens by the International Agency for Research on Cancer. Carcinogenic N-nitrosamines — principally N-nitrosodimethylamine (NDMA) and N-nitrosodiethylamine (NDEA) — are formed in abundance during the preparation of widely consumed Nigerian traditional processed meats including suya, kilishi, and balangu. This original investigation combined a six geopolitical zone of Nigerian market survey with laboratory-controlled model system experiments, effects of processing parameters on N-Nitrosamine formation …

Studies on Zooplankton Diversity of Manar Reservoir with Selected Physico-Chemical Parameters, Maharashtra
Abstract: Freshwater reservoirs in India are increasingly exposed to anthropogenic pressures, such as agricultural runoff, domestic sewage discharge, and water level fluctuations, which significantly influence nutrient dynamics and aquatic ecosystem stability. Biomonitoring using plankton communities provides an effective approach for evaluating ecological health, as these organisms respond rapidly to changes in physico-chemical conditions. The present investigation was carried out to assess the environmental status and trophic condition of Manar Reservoir, located …

Design and Fabrication of Biofilter and Piping in Soilless Farming
Abstract: The most prevailing problems with the modern world are food and water Crises. It is neither possibleto consume the chemically contaminated food nor grow own plants, thanks to scarcity of water andland. Under such Conditions, there arises a requirement for portable agricultural system which Usesless water, space and is only organic. One such solution may be a small scale aquaponic system.Aquaponics uses fish waste to supply nutrients for plants, the …

Ameliorating Effect of Vitamin C on Acid Orange 7 Induced Oxidative Stress in the Gill of the Fish, Anabas testudineus (Bloch, 1792)
Abstract: Acid orange 7, an azo dye, was exposed to Anabas testudineus at a sublethal concentration (0.27 g/l) for 24, 72 and 96 h in order to evaluate the antioxidant status in the gill tissue. In addition, vitamin C at 0.55 g/l was exposed for 7 days after the dye exposure. Acid orange 7 decreased the body weight of fish, whereas mucous deposition increased significantly as the first line of defensive …
