Abstract
The aim of this study was survey of Rotifers community of warm water fish ponds in Gonbade Kavous region at east of Golestan Province. Samplings were done monthly during one culture period from June to November 2011. Finally, 8 genuses were identified and recorded. The results show that the highest and lowest frequency percent of genus belongs to Brachionus sp, Asplanchna sp, Philodina sp, Rotaria sp, Adineta sp, Polyarthra sp, Gastropus sp and Keratella sp with 73.6, 7.6, 5.3, 5.2, 4.4, 1.3, 1.3 and 1.3 % respectively. Logarithm mean of rotifer density had no significant differences between different ponds (P>0.05) but this value was significant differences between different months and seasons (P<0.05). So, that the highest and lowest density belongs to June and September months. But, spring and fall seasons had highest and lowest density. The analysis between Rotifers community and water physico-chemical parameters shows no significant correlation. The results show that Rotifers community of fish ponds affected by pond trophy, climate condition and culture fishes.

Abstract
The present study evaluated the effect of dietary waste date meal (WDM) on body chemical composition and fatty acids profile of fingerling cyprinus carpio. Fish were fed with fFour experimental diets with three replicates including control treatment (no additional WDM; T1), 5% WDM (50 gr/kg; T2), 10% WDM (100 gr/kg; T3) and 15% WDM (150 gr/kg; T4). Totally, 168 fish with initial weight of 2.44±0.02 g were fed at a rate of 5 % body weight 3 times per day for 12 weeks. No significant differences were found in body composition among treatments (P>0.05). All of the body fatty acids showed significant differences among different treatments (P<0.05). The highest amounts of MUFA+PUFA, PUFA/SFA, MUFA+PUFA/SFA, ω3, and EPA+DHA were observed in control treatment (T1), and treatment (T2) with 5% WDM showed the lowest amounts of MUFA, PUFA, MUFA+PUFA, PUFA/SFA, MUFA+PUFA/SFA, ω3, ω3/ω6, DHA/EPA and EPA+DHA except for SFA and ω6/ω3 that showed the highest values than other treatments. Atherogenic index (AI) showed no significant differences among different treatments (P>0.05), but significant differences were observed in Thrombogenic index (TI) among different experimental treatments (P<0.05). The 5% WDM and control treatments showed the highest and lowest values of both indices, respectively. Generally, treatments of 10 and 15% WDM (T3 amdT4) showed moderate performance compared to other experimental treatments. In conclusion, diatary WDM can improve the chemical body composition and saturated and unsaturated fatty acids contents of common carp fingerlings
