Estimation 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...
متن کاملReproductive characteristics of Liza parsia (Ham.) inhabiting south- west coast of Bangladesh
In order to determine the reproductive characteristics of Liza parsia, a fish of commercial importance, the GSI, egg diameter, sex ratio and fecundity were examined in 331 specimens caught monthly for a period of ten months from September 2006 to June 2007. According to the GSI and egg diameter, the reproduction period of Liza parsia was determined to be in November to March with two peaks in t...
متن کاملToxicity of dispersant application: Biomarkers responses in gills of juvenile golden grey mullet (Liza aurata).
Dispersant use in nearshore areas is likely to increase the exposure of aquatic organisms to petroleum. To measure the toxicity of this controversial response technique, golden grey mullets (Liza aurata) were exposed to mechanically dispersed oil, chemically dispersed oil, dispersant alone in seawater, water-soluble fraction of oil and to seawater as a control treatment. Several biomarkers were...
متن کاملAnalysis on Gonadosomatic Index and Fecundity of Terapon Puta from Nallavadu Coast Pondicherry
In the present study fecundity of Terapon puta was estimated for 47 matured females from the Bay of Bengal, Pondicherry. The fecundity (F) was found to range from 20,002 to 1,23,042 in fishes between 134-219mm Total length(TL) and 30-78 gm weight respectively. The co-efficient of correlation for F/TL (log F = 0.790+1.731 log TL), F/SL (log F = 0.799+1.773 log SL), F/TW (log F = 2.590+0.450 log ...
متن کاملReproductive biology of the golden grey mullet, Liza aurata in the Iranian coastal waters of the Caspian Sea
The paper focuses on some of the biological characteristics of golden grey mullet, Liza aurata in Iranian waters of the Caspian Sea. Samples of commercial catch of mullet obtained by means of beach seine fishing cooperatives along the Iranian coasts of Caspian Sea (2007-2008) as monthly interval. Samples subjected to biometric measurement to specify their biological characteristics. The male/f...
