Static bioassays were made in the laboratory to determine lethal concentration of pyrethroid pesticide fenvalerate [(RS)-alpha-cyano-3-phenoxybenzyl (RS)-2-(4-chlorophenyl)-3-methylbutyrate] for freshwater catfish Clarias gariepinus and effects sublethal concentrations on some biochemical parameters fish. For exposure periods 24 96 h, LC50 values ranged from 5.83–4.76 μ g/L 4.24–2.94 g/L, respectively water acetone soluble fenvalerate. Two used parameters: 2.1 h 1.4 exposure, both...
Abstract Lethal concentrations (LC50) of a synthetic pyrethroid pesticide, fenvalerate, for three species air breathing fish Clarias batrachus, Channa punctatus and Heteropneustes fossilis were determined under water acetone soluble condition in the laboratory using static bioassay procedure American Public Health Association (APHA,1995). Acetone fenvalerate was found more toxic than water-soluble irrespective exposure periods. The LC50 value upon 96 days to C. H. 1.35, 1.0 0.65 µg L−1,...
Since ancient times traditional herbal medicines has been the basis of treatment for many ailments. Extracts medicinal plants are rich source unique phytochemicals. In present study extract 12 pteridophytes collected from Southern Assam were studied antibacterial activities. The frond these species was tested against five non-pathogenic and pathogenic bacteria, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus Proteus vulgaris. results obtained indicated that...
Early fingerlings of Anabas testudineus were nurtured in the laboratory for six weeks under altered nutritional status (different dietary protein level and source) feeding regimes (ad libitum, ‘limited’, ‘starvation’ intervals). Their RNA/DNA, Ca/P ratios biosynthesis determined with highly sensitive fluorescence technique, spectrophotometer liquid scintillation system respectively. Well-fed early (4-6 age group) having higher RNA/DNA (2.11), (1.82) ratio rates both muscle liver have...
Studies underin vitro conditions withCuscuta stem tips have revealed that the parasite depends on host for supply of all essential requirements its growth. The vestigial photosynthetic apparatus inCuscuta cannot meet total requirements. Thus energy it primarily host. Inorganic nutrients seem to be secondary importance and perhaps help some extent in independent metabolic pool. Carbohydrates, particularly sugars, are presumably tapped by from translocating channels further utilised own...
