An experiment was conducted to evaluate, the use of extruded chickpea, common bean and red lentil meals as dietary protein source for juvenile rainbow trout. Three experimental diets were formulated based on a reference diet, which composed of 70% reference diet and 30% test ingredient. The diets were given as triplicate groups of juvenile rainbow trout (initial weight of 50 g) to apparent satiation twice daily. There were no significant differences among the groups fed chickpea, common bean and reference diet, for weight gain, specific growth rate and feed conversion ratio, but there were significant differences among these groups and red lentil group in these respects. There were no significant differences in digestibility of protein between the fish fed chickpea and reference diets and chickpea and common bean diets, but the red lentil diet gave lower protein digestibility. Apparent protein digestibility coefficients of the ingredients were determined high for extruded chickpea (80.65%), mid-range for extruded common bean (72.91%) and low for extruded red lentil meals (50.07%). The results indicated that extruded chickpea and common bean meals have higher potential than red lentil meal for use as dietary protein source in diets for juvenile rainbow trout. |

In this study, effect of dietary supplementation of different rates (10% Group B, 20% Group C, 30% Group D, 40% Group E) of spirulina (Spirulina platensis) on growth and feed conversion in guppy (Poecilia reticulata) was compared with a commercial stamp food (Group A). Fish fed 40% spirulina performed better than those fed lower levels. At the end of the experiment, there were no significant differences between the all groups in terms of average final weights (p>0.05). No significant differences were observed in specific growth rate, feed conversion rate and weight gain. However, there were significant differences in terms of feed conversion rate between groups (p<0.05) and it was the highest in Group E (1.090±0.044) and the lowest in Group A (2.312±0.071). Therefore, the best growth rate (1.933±0.009) and live weight gain (0.085±0.006 ) were recorded in Group |
