The length-weight relationship (LWR) and relative condition factor for the two freshwater fish species, malabar sprat, Ehirava fluviatilis quoy’s garfish, Hyporhamphus quoyi were estimated from potamon zone of Thamirabarani river, Eastern Slope Western Ghats, Southern Tamil Nadu, India. Fish samples caught fortnightly using various fishing gears viz., cast net seine between November 2020 Octobe...

115 samples of Labeo calbasu ranged 8.0-17.9cm length with mean11.90±1.96 and 4.9-68.5g weight with mean 22.25±12.54 from the River Chenab, Southern Punjab, Pakistan were analyzed to investigate length-weight relationships (LWR) of fish in relation to condition factor (K). Standard length (SL), fork length (FL), head length (HL) head width (HW), body girth (BG), dorsal fin length (DFL), dorsal ...

Materials Methods: sampling areas are Bayramiç Reservoir tributaries o...

Length-weight relationship (LWR), condition factor (K) and stomach content of three cichlid fishes (Hemichromis bimaculatus, Sarotherodon melanotheron, and Chromidotilapia guentheri) were calculated at Eleiyele reservoir, Nigeria, Africa. The fish were collected monthly from fishermen during the dry season (January-March 2001) and the rainy season (April, May, June 2001). Gill nets of mesh size...
