Boylamanın ve Büyük Bireylerin Yüzer Ağ kafeslerde Asya Kedi Balıklarının (Pangasianodon hypophthalmus) büyümeleri üzerine etkisi

Abstract

Seyhan Baraj Gölünde yüzer ağ kafeslerde yapılan 60 günlük besleme çalışmasında ortalama 29 g lık Asya Kedi Balığı (Pangasianodon hypophthalmus) genç bireyleri, boylanarak farklı 3
deneme grubu halinde yetiştirilmiştir. Deneme grupları %100 aynı boyda olan küçük bireylerden oluşan (B) grubu, %50 küçük + %50 büyük bireyden oluşan (K1) karışık grup ve %75 küçük + %25 büyük bireylerden oluşan (K2) karışık grubundan oluşturulmuştur. Deneme sonunda homojen boya sahip (B) grubunun bireylerinin (171,26g) 159,92 g ve 151,17 g ortalamaya ulaşan karışık gruplardan (K1 ve K2) daha iyi büyüdüğü saptanmıştır. Sonuç olarak boylamanın 30 g lık asya kedi balığı bireylerinin büyümesini olumlu yönde etkilediği tespit edilmiştir.

The effects of larger fish and size grading on growth performance of Asian cat fish (pangasianodon hypophthalmus) at floating cages

Abstract

Young Asian catfish (Pangasianodon hypophthalmus) have been cultured for 60 days feeding period in floating cages in Seyhan Dam Lake Adana. Fish were graded as a triplicate group. Research trails were established as 100% small group (B), 50% small + 50% large fish (group K1), 75%small + 25%large fish (group K2). At the end of the study best growth rate was
obtained from group B (171,26g), and the other groups (K1 and K2) were 159,92 g and 151,17 g. respectively. As a conclusion, the growth of young Asian catfish (30 g) was positively affected by size grading application in cage culture conditions.
