Abstract AR
الهدف من الدراسة الحالية هو لإجراء توليد مستحث لإناث و ذكور سمكة الكارب الاعتيادي لغرض متابعة التطورات الجنينية و اليرقة خلال فصول السنة.
لتحقيق ذلك حقنت الأسماك بهرمون الاوفابريم الصناعي بواقع جرعة واحدة للذكور و جرعتان للإناث و بتركيز 0.4 إلى 1 ملم لكل كغم من وزن الجسم.
حدث التفريخ بعد 6-5 ساعات و بدرجة حرارة 29-26 مئوية في الصيف 19-17 مئوية في الشتاء.
لوحظ أن البيوض المصخبة لزجة و بيضاء إلى صفراء اللون و كروية الشكل و بقطر 10-0.8 ملم.
أن الاستجابة الواضحة للهرمون و معدل التخصيب و التفريغ و قصر الفترة اليرقية يشجع على استخدام هذا الهرمون في التفريخ التجاري لهذه الأسماك.
Abstract EN
The aim of the present study was to perform induced breeding and to observe embryonic and larval development stages in different seasons for mature male and female Koi carp, Cyprinus carpio, was done by administering the synthetic hormone ovaprim, in a single dose for males and a double dose for females at 0.4-1.0 ml/kg body weight via an intramuscular injection.
Spawning occurred between 5-6 hrs after the 2nd injection in summer (April) at a temperature of 26-29 oC and 17-20 0C in winter (December).
Using doses of 0.4ml / kg, 0.7ml / kg and 1.0 ml / kg of ovaprim, the fertilization rate of eggs were obtained at 42.31 %, 54.55 % and 61.82 % in summer and 26.92 %, 38.00 % and 39.23 % in winter.
Hatching rates were 42.78 %, 44.60% and 55.00 % in the summer season and 30.22 %, 31.01 % and 31.67 % in the winter season with the same doses of ovaprim.
The fertilized eggs were adhesive, transparent, and spherical with diameters ranging between 0.8 mm and 1.0 mm and yellowish white in color.
Due to a positive response to the hormone Ovaprim, considerable fertilization and hatching rate, short embryonic period and larval development, it is possible to conduct a successful breeding program of this species commercially.
