Abstract

The effect of cadmium and lead on glycogen, protein and lipid contents of gill, liver and muscle of Indian major carp, Cirrhinus mrigala have been studied. The fish were exposed to predetermined LC₀ (0.98 and 19.352ppm) and LC₅₀ (0.132 and 21.849ppm) concentrations of cadmium chloride and lead acetate, receptively for 96 hours. For chronic exposure 1/10^th and 1/20^th concentrations of LC₅₀ values have been used for 30 days. Both the heavy metals showed decrease in glycogen, protein and lipid content in all the tissues. The significant alterations showed toxic effects of heavy metals at biochemical levels.

Abstract

The acute (96 hrs) effects on exposure to sublethal and lethal concentrations of synthetic pyrethroids, fenvalerate 20 EC and cypermethrin 25 EC were studied by a static bioassay method on the fingerlings of a freshwater carp, Labeo rohita. The sublethal concentrations of fenvalerate and cypermethrin were 2.7 ppb and 3 ppb while lethal concentrations were 4.8 ppb and 5 ppb respectively. The rate of oxygen consumption was determined at these concentrations after every 24 hours. It was found that, as compared to the control, there was change in the rate of oxygen consumption. In general, there was increase in the rate of oxygen consumption due to the effect of both the pyrethroids.

Abstract

Thorell established the family Oxyopidae in 1870 consisting of the type genus Oxyopes which was established by Latrielle in 1804. Walckenaer for the first time recorded the genus from Indian sub-continent in 1805. Remarkable works in India on the family Oxyopidae were done by Thorell (1887), Tikader (1965), Gajbe (1999,2000, and 2008), Biswas and Roy (2005). While examining the collections from plateau region of Satara Dist (Maharashtra), we found an Oxyopes species that is new to science. We diagnosed it and describe, illustrate here as sp.nov. in the present study under the name Oxyopes sataricus.

Abstract

Araneidae includes 29 genera and 154 species from the Indian sub-continent (Sebastian et al., 2009) The genus Arachnura Vinson, 1863 is represented by two species only; A. angura Tikader, 1970 from Gazing, Sikkim (Lat 27°20' N & Lon 88°40') and A. melanura (Simon, 1867).
