اثر تركيبات يوني اسپرم بر كارايي تكثير مصنوعي ماهي سفيد (Rutilus frisii kutum kamensky 1901) مهاجر به رودخانه سفيد رود

Study on Effect of ionic compounds of sperm on efficiency of artificial reproduction in Kutum fish (Rutilus frisii kutum Kamensky, 1901) immigrant to the Sefid River

در اين پژوهش برخي از تركيبات يوني مولدين ماهي سفيد و روابط آنها با كارايي تكثير مصنوعي و عوامل اسپرم شناختي مورد بررسي قرار گرفت به طوري كه در 20 نمونه از مولدين نر كه 10عدد 3 ساله و 10عدد 4 ساله بودند ميانگين و انحراف معيار يون ها در ماهيان 3و4 ساله مورد بررسي به ترتيب meq/l 7/5 ± 96 و 4/6 ± 6/96 سديم ، meq/l 6/1 ± 32 و 4/2 ± 5/34 پتاسيم، mg/dl 43/1 ± 23/4 و 02/1 ± 58/3 كلسيم، meq/l 62/0 ± 25/2 و 47/0 ± 27/2 منيزيم، meq/l 95/7 ± 1/100و 68/7 ± 3/107 كلر بدست آمد. ارتباط يون هاي پتاسيم، كلر با درصد لقاح و درصد تفريخ مثبت و مستقيم بود ولي ارتباط سديم ، منيزيم و كلسيم با درصد لقاح و درصد تفريخ منفي و عكس به دست آمد.

In this study some of the ionic composition indices and their relations with the efficiency of reproduction and artificial spermatozoa maturation factors in Kutum Rutilus frisii kutum were measured. For these propose examined the 20 samples that 10 male specimen from the maturation of 3 years, 10 male specimen with 4 years were examined. Results shows that the average and standard deviation of ions properties in fish 3 and 4 years include: 96±5 .7 meq/l and 96.6±6 .4 for Na, 32±l.6 meq/l and 2.4±34.5 for Potassium, 4.23±1.43 mg/dl, 3.58±1.02 for calcium, 2.25±0.62 meq/l and 0.47±2.27 for Magnesium, 100.1±7.95 meq/l and 107.3±7.68 for Cl were investigated respectively. According to the results relation between potassium and chloride ions with fertilization rate and hatching percentage were significantly positive and the direct relationship of sodium, magnesium and calcium with fertilization rate and hatching percent were significantly negative.
