Salmo trutta abanticus’larda Fertilizasyon Başarısı ile Spermatozoa Motilitesi, Yumurta Büyüklüğü ve Yumurta Verimi Arasındaki İlişki

Öz

Abant alabalıklarından Salmo trutta abanticus sperma ve yumurta abdominal masaj yoluyla alınmıştır. Fertilizasyon oranları ile spermatozoa motilitesi, yumurta büyüklüğü ve yumurta verimi arasındaki ilişki araştırıldı. Fertilizasyon oranı ile spermatozoa motilitesi r=0.111, p>0.01 ve fertilizasyon oranı ile yumurta büyüklüğü r=0.459, p>0.01 arasında pozitif yönde korelasyon belirlenirken fertilizasyon oranı ile yumurta verimi r=-0.535, p>0.01 arasında ise negatif yönde bir korelasyon belirlenmiştir. Sonuç olarak, spermatozoa motilitesi ve yumurta büyüklüğündeki artışların Abant alabalık Salmo trutta abanticus ’larında fertilizasyon başarısını olumlu yönde etkilediği belirlenmiştir

Anahtar Kelimeler

Relationship Between Spermatozoa Motility, Egg Size, Fecundity and Fertilization Success in Salmo trutta abanticus

Abstract

Sperm and eggs were collected without anesthesia by abdominal massage from Salmo trutta abanticus. The relationship between spermatozoa motility, egg size, fecundity and fertilization rates were investigated. Fertilization rates ranged from 72% to 80% and correlated positively with spermatozoa motility r= 0.111, p>0.01 and egg size r=0.459, p>0.01 . On the other hand, negative correlation r=-0.535, p>0.01 was evaluated between fertiliation rates and fecundity. Consequently it was determined that increase in spermatozoa motility and egg sizes effect the fertilization success positively in Salmo trutta abanticus
