Hardani hardani_rezvan@yahoo.com N. Ghotbeddin ghotbeddiny2005@gmail.com E. Rajabzadeh Ghatrami e.rajab@yahoo.com In this study, the effects of starvation and re-feeding on growth performance and body biochemical composition of Blue Streak Hap (Labidochromis caeruleus) were conducted at autumn 2014. A total of 450 fish were assigned to 5 treatments with 3 replicates. 15 tanks were prepared with a volume of approximately 120 liters and trial period was considered 48 days in experimental conditions. Treatments included 0, 2, 4, 8 and 16 days of starvation. Fish after two weeks of acclimatization to the laboratory conditions, were examined based on the pattern of starvation and re-feeding. The results of the growth performance and biochemical composition showed that, treatments 2 and 4 days of starvation, compared to the control group were able to compensatory growth in the period of re-feeding and did not show a significant difference in any of the treatments (P>0/05). But treatments 8 and 16 days of starvation not be able to compensate growth and expenditure of excess metabolic energy due to starvation period, and had significant differences in the growth and nutritional factors as well as significant differences in the lipid and protein level compared to the control group.

Taiebzadeh M. Velayatzadeh mv.5908@gmail.com The present study was carried out to investigate accumulation of eleven toxic and essential trace elements in muscle and shell of Potamon persicum from Kakareza River in Lorestan Province (Iran) collected in summer and autumn, 2011. The elements level were analyzed by Perkin Elmer 4100 Zl atomic absorption and data were analyzed statistically using one-way ANOVA and Duncan’s test by SPSS17. The results showed that the highest and lowest concentration of Hg, Cd, As, Fe, Co and P were in shell collected in autumn and muscle collected in summer, respectively. Also, the highest and lowest concentration of Pb, Zn, Ca and K were observed in shell collected in summer and muscle collected in autumn, respectively. The highest and lowest Cu concentration was measured in the shell and muscle of P. persicum collected in summer, respectively. Concentration of Hg, Cd, As, Pb, Zn, Cu, Fe, Co, Ca, K and P in the shell of P. persicum were higher than the muscle both in summer and autumn. According to the results, concentration of as and Cd in P. persicum muscle were higher than WHO standard limits, while concentration of Hg and Pb were still lower than that limitation.
