Important physicochemical characteristics of water like dissolved oxygen content, pH, and so forth were found to change in a dose dependent manner, showing a negative correlation with the nanoparticle concentration, when ZnS nanoparticle (NP) was exposed to water. This observation could be attributed to the enhanced photooxidation property associated with ZnS in its NP form. Under this situatio...

The present investigation was carried out seasonally from October 2008 to September 2010, to study the impact of helminth parasites of catfishes of Lucknow. The fish fauna viz., Clarias batrachus, Heteropneustes fossilis, Wallago attu, Mystus vittatus and Rita rita were carried trematode, cestode, nematode and acanthocephalan parasites communities singly or mixed. The collected fish species inc...

Length–weight relationship, condition factor (K), relative (Kn), fecundity and egg diameter of Mystus vittatus (Bloch, 1794) were estimated from 120 individuals collected the Mouri river Khulna district, Bangladesh during 7th August to 25th October 2006. The total length (LT) ranged 7.2 cm (body weight (W) 6.9 g) 13.4 (W=24.2 for male 12.1 (W=14.39 13.6 (W=23.29 female. logarithmic relationship...

The aim of this study is to examine the relationship between length, weight, condition factor (K), and relative (Kn) Mystus tengara (Hamilton, 1822), with special emphasis on seasonal variation growth patterns, productivity, stocks, conservation in two distinct ecosystems: pond river. results demonstrate that species did not strictly adhere predicted cube law had allometric patterns throughout ...

This study dealt with physical, chemical and microbiological characteristics of the lipid obtained from Mystus vittatus and some nutritional properties of the fish. The fish was found to contain moisture 76.98%, calcium 521.072 mg / 100gm, vitamin C 11.276 mg / 100 gm., lipid 1.89%, and protein 10.94% respectively. The specific gravity, refractive index and co-efficient of viscosity of this lip...
