Abstract

In this study, fertilisation, eyeing, hatching and survival rate of Abant and Rainbow Trout were compared with eachother. Wild Abant Trout broodstocks obtained in Abant Lake and Cultured Rainbow Trout broodstocks obtained in Gölköy Fish Production Center were used. The diameter and wet weight of Abant and Rainbow Trout eggs has been found as 5.01±0.16 mm, 80.13±0.78 mg and 5.06±0.18 mm, 81.22±0.86 mg in trial I, 5.20±0.19 mm, 84.80±1.42 mg, 5.10±0.29 mm and 110.13±0.17 mg in trial H respectively. In both trial I and ü, and 46.5% of the fertilised eggs ofAbant Trout was hatched after 52 days (439 day-degree) and 47 days (442 day-degree) and 76.0; 72.0% of the fertilised eggs of Rainbow Trout was hatched after 31 days (295 day-degree) and 30 days (292 day-degree) respectively. In conclusion, while the hatching rate of fertilised eggs ofAbant Trout in trial I was higher than Rainbow Trout in trial I and II, the hatching rate of fertilised eggs ofAbant Trout in trial II was the lowest but eyeing, hatching and survival period of fertilised eggs of Abant Trout was longer than Rainbow Trout as expected.

Özet

Abant ve Gökkuşağı alabalığı yumurtalarının döllenme, gözlenme, larva çıkış ve yaşama oranları karşılaştınlmıştır. Abant Gölü'nden yakalanan yaban Abant alabalığı ile Gölköy Balık Üretme Istasyonu'nda kültür yoluyla yetiştirilen Gökkuşağı alabalığı anaçları kullanılmıştır. Abant ve Gökkuşağı alabalığı yumurta çapı ve yaş ağırlıkları I. denemede 5,01±0,16 mm, 80,13±0,78 mg, 5,06±0,18 mm ve 81,22±0,86 mg, ü. denemede ise 5,20±0,19 mm, 84,80±1,42 mg, 5,10±0,29 mm ve 110,13±0,17 mg olarak ölçülmüştür. I. ve ü. deneme Abant ve Gökkuşağı alabalığı larva çıkış oranlan sırasıyla 52 gün sonra (439 gün-derece) %91,1,47 gün sonra (442 gün-derece) %46,5 ve 31 gün sonra (295 gün-derece) %76,0; 30 gün sonra (292 gün-derece) %72,0 olarak tespit edilmiştir. Araştırma sonunda; I. denemedeki Abant alabalığı yumurtalarının döllenme, gözlenme, larva çıkış ve yaşama oranlan, I. ve ü. denemedeki gökkuşağı alabalığı yumurtalannm döllenme, gözlenme, larva çıkış ve yaşama oranlanndan daha yüksek bulunmasına karşın, D. denemedeki Abant alabalığı yumurtalannm döllenme, gözlenme, larva çıkış ve yaşama oranlan daha düşük bulunmuştur. Fakat, Abant alabalığı larvalan, Gökkuşağı alabalığı larvalanna göre yumurtadan daha uzun sürede çıkmışlardır.
