Studies on length-weight and length-length relationships of a catfish Eutropiichthyes vacha Hamilton (Schilbeidae: Silurifo-
Present study describes the length-weight (LWR) and length-length (LLR) relationships of a freshwater catfish Eutropiichthyes vacha Hamilton from Indus River, Sindh, Pakistan. A total of 281 specimen of E. vacha were collected from fisherman?s catch from February 2005 to January 2006, are used for this study. The parameters a and b of the length-weight relationship were calculated as W= aLb are...
متن کاملUse of RAPD fingerprinting for delineating populations of hilsa shad Tenualosa ilisha (Hamilton, 1822).
RAPD was used to delineate the hilsa populations sampled from the Ganga, Yamuna, Hooghly, and Narmada Rivers at six different locations. Six degenerate primers were used to generate the fragment patterns from the samples collected. All primers were highly polymorphic and generated high numbers of amplification products. Nei's genetic distances were calculated between locations. The overall aver...

متن کاملInvestigation of Stock Status of Hilsa shad (Tenualosa ilisha Hamilton, 1822) in the Southern Waters of Iran
Hilsa shad (Tenualosa ilisha Hamilton, 1822) is a migratory fish and as one of the most important species in the southern parts of Iran, so that during the last decade, the amount of its catch has fluctuated a lot. Due to the limited data available on the stock of this species in southern waters, it is not possible to use models based on complementary data to assess its stock. In the present st...
متن کاملFunctional ureogenesis and changes of amino acid metabolism in amphihaline shad hilsa (Tenualosa ilisha, Hamilton-Buchanan) while inhabiting in estuary and freshwater habitats.
The possible occurrence of a functional ornithine-urea cycle (OUC) and changes of activity of key amino acid metabolism-related enzymes were studied in the amphihaline shad hilsa (Tenualosa ilisha) that were collected from estuarine water of Kakdwip and from freshwater river basin of Bhrahmaputra during the breeding season. Very high concentration of urea was detected in different tissues and p...
