  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

  In this research, population structure of the species Aphanius danfordii found in Sirakaraağaçlar stream has been studied. During the research, sex, age, weight and length composition of 452 fishes has been examined and lenght-weight relationship and Von Bertalanffy growth function has been calculated. Female-male sex proportion has been calculated as 1.06:1.00, lenght-weight relationship and Von Bertalanffy growth function has been calculated as W = 0.0139 L3.1641, Lt = 5.149 (1-e-5.945 (t-0.502)) and Wt = 2.483 (1-e-5.945 (t-0.502)).

  The effects of soybean and hazelnut meals as partial and total replacements of fish meal were studied on the growth performance and feed utilization of Koi carp juvenile (Cyprinus carpio L., 1758). Juvenile fish (mean initial weights 0.12 g) were fed five isonitrogenously (350 g kg‾1) and isocalorically (4.20 kcal g‾1) diets with 50 or 100% of the fish meal protein replaced by soybean and hazelnuts protein. The control diet contained fish meal as major protein source. A total of 225 juvenile koi were randomly assigned to each treatment which was replicated three times with 15 fish each. The fish were fed with these diets for 65 days. The results showed that Final Body Weight (FBW), Relative Growth Rate (RGR) and Protein Efficiency Rate (PER) were not significantly different among groups. Fish fed control, 50% SM, 50% HM and 100% SM diets had similar Specific Growth Rate (SGW) values while fish fed the 100% HM diet had lower SGR values than those of other diets (p<0.05). The FCR values of fish fed 50% SM and 50% HM diets were significantly different than that of 100% HM (p<0.05). The highest FCR was obtained from 50% HM diet. The results indicated that koi carp juvenile can be cultivated with feeding diets containing 50% SM, 100% SM and 50% HM without any adverse effect on growth performance of fish.
