Comparison of the growth performance and mortality in Abant trout (Salmo trutta abanticus Tortonese, 1954) and rainbow trout (Oncorhynchus mykiss Walbaum, 1792) under farming conditions

Çalışma, Bolu-DSİ Gölköy Balık Üretme istasyonu'nda gerçekleştirilmiş ve 15 Şubat 2000 ile 31 Ocak 2001 arasında 350 gün devam etmiştir. Bu çalışmada, Abant Gölü'nden yakalanan Abant alabalığı anaçlarından sağlanan yumurtalardan çıkan larvalar ile Gölköy Balık Üretme istasyonu'nda yetiştirilen gökkuşağı anaçlarından sağlanan yumurtalardan çıkan larvalar kullanılmıştır. 1. ve 11. deneme 8 grup (4 adet Abant ve gökkuşağı alabalığı deneme, 4 adet Abant ve gökkuşağı alabalığı paralel grubu) olarak düzenlenmiştir. Her 2 deneme de toplam 1784 adet larva kullanılmıştır. Deneme sonunda, Abant alabalığı ortalama yaş ağırlığı 5 gram civarında bulunmasına karşın, en yüksek ağırlık artışı gökkuşağı alabalıklarında bulunmuştur (I. ve II. deneme de 116,202 ile 173,315 gram arasında). Gökkuşağı ve Abant alabalığı grupları arasında ortalama son kondüsyon faktörü (CF) bakımından farklılığın önemli olduğu bulunmuştur (P < 0,001). I. ve II. denemede, türler arasında spesifik büyüme oranı farklıdır (P < 0,01) (P < 0,05). Sonuç olarak; tank yetiştirme koşullarında Abant alabalığının gelişim performansının arzu edilen seviyede olmadığı görülmüştür. Buna karşın; gökkuşağı alabalığının büyüme ve yaşama oranı Abant alabalığı büyüme ve yaşama oranından daha iyi olduğu tespit edilmiştir.

Çiftlik koşullarında Abant Alabalığı (Salmo trutta abanticus Tortonese, 1954) ile Gökkuşağı Alabalığı (Oncorhynchus mykiss Walbaum, 1792)' nın gelişim performansı ve ölüm oranlarının karşılaştırılması

This experiment was conducted between 15th February 2000 (day 1) and 31st January 200fl (day 350) at the DSI-Gölköy Fish Production Station, Bolu (Turkey). Abant trout larvae obtained from eggs of wild Abant trout broodstocks in Lake Abant and rainbow trout larvae obtained from eggs of the hatchery broodstocks in Gölköy Fish Production Station were used. Trials I and II involved eight groups (four Abant and rainbow trout experimental groups, and four Abant and rainbow trout parallel groups). A total of 1784 larvae was used in both the trials. At the end of the experiment, although the mean wet weight of Abant trout was found to be around 5 g, the maximum increase in weight was found in rainbow trout (between 116.202 and 173.315 g in trials I and II). Final mean condition factors (CF) differed between the Abant and the rainbow trout groups (P < 0.001). The specific growth rate (SGR) exhibited significant differences between trials I and II for the Abant and rainbow trout groups (P < 0.01) (P < 0.05). It is concluded that the desired level of growth performance of Abant trout was not obtained in tank conditions. In contrast, the growth and survival rate of rainbow trout were clearly better than those of Abant trout.
