Abstract

This study was carried out to examine the effect of Fructooligosaccharide as a source of prebiotic, and commercial dry yeast (Saccharomyces cerevisiae) as a source of probiotic and their combination in different level as a source of synbiotic. The experiment was conducted in the fish laboratory of Animal Production Department, Faculty of Agricultural Sciences of Sulaimani University. The trials lasted for three months after 21 days of adapting period 120 common carp fingerlings with an average weight of 20 ±2 gm, were used to test the effect of different levels of the Fructooligosaccharide, yeast and their combination. In T1 fish were fed a diet with 2.5 gm/kg Fructooligosaccharide, in T2, fish were fed a diet 2.5 gm/kg yeast, T3 represents the third treatment, in which fish were fed on a diet 5 gm/kg Fructooligosaccharide. While, in T4 fish were fed a diet 5 gm/kg yeast, and T5 2.5 Fructooligosaccharide: 2.5 Yeast (gm/kg), T6 was 5 Fructooligosaccharide: 5 yeast (gm/kg), T7 2.5 Fructooligosaccharide: 5 Yeast gm/kg), while T8 5 Fructooligosaccharide, 2.5 (gm/kg) Yeast. Each treatment in three replicates in which five fingerlings common carp were stocked in plastic tanks, which fed the experimental diets twice daily. Blood parameters of tested fish showed significant differences in Red blood cell count (1012 cells/l) in T5 and T7 by 1.235 and 1.260, respectively. Hemoglobin (g/dl) data were 117.000 in the fifth treatment. The mean corpuscular hemoglobin (pg/cell) was 121.400 in T2, 137.850 in T3, 121.050 in T4, and 135.300 in T6; mean corpuscular hemoglobin concentration (g/l) was 924.000, in the seventh treatment, mean corpuscular volume were (fL) 232.500 and 233.050 in T4 and T8 respectively. There were different effects of the treatment in the studied blood parameters in which the level of 2.5 g/kg in both Fructooligosaccharide and dry yeast affect significantly the Red blood cell, White blood cell and Hemoglobin.

Abstract

This study was conducted in Ranya Lakelet/Dukan, the study started at the end December of 2014 to early April of 2015, heavy metal concentration in water, sediment and fish organs (skin, gills, intestine, liver and muscle.). The experiment was conducted in the laboratory of Chemistry Department, Faculty of Science at University of Raparin, Sulaimani, Kurdistan Region - Iraq. The trials for the sampling species lasted for three months (January, February and March). Sixty eight common carp taken as a sample, then divided into four length groups (20-30(19 fishes); 31-40(29 fishes); 41-50(11 fishes); 51> cm (9 fishes)). Heavy metals contents analysed in water, sediment and fish organs, including Cadmium (Cd), Zinc (Zn), Nickel (Ni), Chromium (Cr), Copper (Cu) and Lead (Pb). The study results showed that the mean concentrations heavy metals (Cd, Zn, Ni, Cr, Cu and Pb) were below detection limit (1µg/L) except Zn, which it was 8.18 µg/L in filtered water. Whereas, the mean concentrations of heavy metals (Cd, Zn, Ni, Cr, Cu and Pb) in sediments were 6.90 µg/L, 146.29 µg/L, 151.46 µg/L, 161.74 µg/L, 38.86 µg/L and 92.49 µg/L, respectively. The higher concentrations of heavy metal (Cd, Zn, Ni, Cr, Cu and Pb) in different organs were 0.69 µg/L, 6352.84 µg/L, 16.52 µg/L, 9.25 µg/L, 42.18 µg/L, and 11.44 µg/L, respectively. While the lower concentration of heavy metal (Cd, Zn, Ni, Cr, Cu and Pb) in different organs were BDL, 208.53 µg/L, 2.93 µg/L, 2.93 µg/L, 20.13 µg/L, BDL, respectively. This study showed that storing of heavy metals occurs by this order; Zn>Cu>Ni>Cr>Cd>Pb. Although the trend of heavy metals concentrations according to length groups generally represented as follows; group4> group3> group2> group1.

أجريت الدراسة الحالية في بحيرة رانية/ التابعة لبحيرة دوكان، للفترة من نهاية شهر كانون الاول من 2014 الى بداية شهر مايس من 2015. شملت الدراسة قياس بعض العناصر الثقيلة (الكادميوم، الزنك، النيكل، الكروم، النحاس، الرصاص) في الماء والرواسب وبعض أعضاء (الجلد، الكبد، الغلاصم، الامعاء، عضلات) جسم الاسماك. أجريت الدراسة في مختبر الاسماك في قسم علوم الكيميا / جامعة رابةرين/ السليمانية/إقليم كردستان، العراق. أجريت هذه الدراسة لبيان تأثيرها على الحالة الصحية العامة لأسماك الكارب الشائع (Cyprinus carpio) في البحيرة. صيدت 68 سمكة كارب عادي والتي قسمت الى أربع مجاميع طولية ( 20-30 (19 سمكة): 31-40(29 سمكة) : 41-50(11 سمكة) : 51<(9 سمكة)) سم، والتي أستخدمت لدراسة تركيز محتواها من بعض العناصر الثقيلة (الكادميوم، الزنك، النيكل، الكروم، النحاس، الرصاص)في كل من الماء والرواسب وفي كل من جلد وغلاصم و الامعاء وكبد وعضلات أسماك الكارب العادي. وجد أن متوسط تركيز العناصر الثقيلة (الكادميوم، الزنك، النيكل، الكروم، النحاس، الرصاص ) كانت غير محسوسة ماعدا الزنك االتي µg/L 8.18 وفي الرواسب كانت 6.90 µg/L, 146.29 µg/L, 151.46 µg/L, 161.74 µg/L, 38.86 µg/L و 92.49 µg/L على التوالي. كانت اعلى التراكيز للعناصر الثقيلة (الكادميوم، الزنك، النيكل، الكروم، النحاس، الرصاص ) في بعض أعضاء جسم السمكة 0.69 µg/L, 6352.84 µg/L, 16.52 µg/L, 9.25 µg/L, 42.18 µg/L و 11.44 µg/L على التوالي، بينما أقل التراكيز كانت BDL, 208.53 µg/L, 2.93 µg/L, 2.93 µg/L, 20.13 µg/L, BDL على التوالي. أظهرت نتائج الدراسة الحالية بأن تسلسل العناصر كانت كالآتى: الزنك> النحاس> النيكل> الكروم> الكادميوم> الرصاص. وتمثل ترتيب العناصر الثقيلة بالنسبة للمجاميع الطولية بالآتي: group4> group3> group2> group1.
