Use 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...
متن کاملLength-Weight, Length-Length Relationship of the Spiny Eel, Macrognathus pancalus (Hamilton 1822) sampled from Ganges and Brahmaputra river basins, India
The freshwater spiny eel, Macrognathus pancalus is an inland water teleost fish commonly known as barred or striped spiny eel found in Asia. The sampling areas were selected which are spatially and geographically different and characterized by different environmental conditions in order to elucidation of ecotype. A total 345 specimens were collected from the sampling sites during January 2008...
متن کاملGonad Histology and Gonadosomatic Index Variations during Gonadal Development of Wild Female Tenualosa ilisha
Hilsa shad (Tenualosa ilisha) is an anadromous species which has reproductive migration from the Persian Gulf to the river. Morphological properties and histological changes in oocyte of Hilsa shad in two different environments (salt water and fresh water in Khuzestan province) were studied with respect to its reproductive cycle. Twenty fish samples with average weight of 830.75±3.25 ...
