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...

The present study investigates the effects of different feeding regimes with rotifers ( Brachionus plicatilis ) and Artemia salina on gene expression digestive enzymes in pikeperch Sander lucioperca larvae at 17 days post-hatch (DPH) over a period 13 days. Five experimental protocols were performed four replicates. At 4 DPH, (total length= 5.62 ± 0.03 mm, body weight = 0.66 0.16 mg) divided int...

The current study evaluated effects of dietary administration doses of Entrococcus faecium on the hematological factors, and disease resistance of Sander lucioperca against Aeromonas hydrophila infection. Fish were fed with dietary administration containing E. faecium doses including of (1010, 108CFU/ g) for diet A1 and A2, respectively in a commercial diet as basal diet were used for 6 weeks. ...

Growth performance, food efficiency and body composition of pikeperch (Sander lucioperca) were investigated with 1 or 2 g/kg L-carnitine added to the diet. Control diet did not contain L-carnitine. Two hundred pikeperch fingerlings (1.63 g, mean weight) were stocked in each 1 m3 concrete tank and fed equally 6 meals per day for 6 weeks. Higher increment in body weight (5.92 ± 0.37 g), the ...
