متن کاملEstimation of Fecundity and Gonadosomatic Index (GSI) of Gangetic Whiting, Sillaginopsis panijus (Hamilton, 1822) from the Meghna River Estuary, Bangladesh
Specimens of Gangetic whiting, S. panijus, were collected from the Meghna estuary to estimate the fecundity and Gonadosomatic Index (GSI) during April-September, 2011. The morphometric and meristic features of the fish were measured. The co-efficient of correlations between total length and head length with other body measurements were significant (P<0.01). The logarithmic length-weight relatio...

Fecundity and gonado-somatic index (GSI) of wild freshwater spiny eel Mastacembelus armatus were estimated from haor region of Kishoreganj district of Bangladesh. Estimated fecundity ranged from 2,235 to 19,493 for the fish measuring from 25 to 54 cm and weighing from 79 to 345 g. The minimum, median and maximum ova diameter was 0.20, 1.90 and 2.20 mm, respectively. The average numbers of ova p...
متن کاملVitamin D3-induced calcemic and phosphatemic responses in the freshwater mud eel Amphipnous cuchia maintained in different calcium environments.
Vitamin D3 (100 ng 100 g body weight-1 day-1) was administered intraperitoneally (i.p.) to the freshwater mud eel Amphipnous cuchia kept in artificial freshwater, calcium-free freshwater, low-calcium freshwater (0.2 mmol/l CaCl2) or calcium-rich freshwater (13.4 mmol/l CaCl2) for 15 days. Analyses of serum calcium and phosphate levels were performed on days 1, 3, 5, 10 and 15 after the beginnin...
متن کاملEffects of amlodipine on serum testosterone, testicular weight and gonado-somatic index in adult rats.
BACKGROUND Calcium ions are vital in many biological processes including hormonal secretion, mitosis, reproduction, fertility and regulation of gene expression. Thus, calcium antagonists who are frequently prescribed for the cure of cardiovascular diseases may affect any of these physiological processes. METHODS This quasi experimental study was done at Army Medical College, Rawalpindi from O...
