Besides traditional methods based on morphological characters, electrophoretic such as SDS-PAGE are preferred by taxonomists to make the right decision in species identification process. In addition, effect of environmental factors, pH, salinity, heat, and temperature protein profiles essential various studies. this study, we aimed determine degree relationship some fish species, Squalius lepid...

Effect of depuration on content geosmin in pikeperch (Sander lucioperca) produced a commercial RAS farm was examined during 15-day period. Concentrations the fish were related to water. For depuration, half water volume 230 m3 production tank replaced daily with geosmin-free After 8 days and absence feeding, reduced from 710 ± 245 ng/kg 165 50 (mean SD, p < .01). Additional for 7 only 135 24 ng...

changes in the fatty acid content, during frozen storage at -24°c of caspian kutum (rutilus frisii kutum), golden grey mullet (liza aurata), common carp (caprinus carpio), pike perch (sander lucioperca) and common kilka (clupeonella cultiventris caspia), caught from south caspian sea were studied in the present work. changes in saturated fatty acids (sfas), monounsaturated fatty acids (mufas), ...
