Farklı Renklerdeki Yemlerin Mozambik Tilapia (Oreochromis mossambicus) Larvalarının Büyüme Performansına Etkileri

Bu çalışma, yem renginin, Mozambik tilapia (Oreochromis mossambicus) larvalarının büyüme performansı üzerindeki etkisini belirlemek amacıyla yapılmıştır. Denemede yumurtadan yeni çıkmış (0,01 g) larvalar 3 litrelik cam akvaryumlara 10 adet balık yoğunluğunda olacak şekilde stoklanmıştır. Deneme boyunca balıklar, 4 farklı renkte (açık kahverengi-kontrol, kırmızı, koyu yeşil ve sarı) deneme yemleri (%37 HP ve %9 HY) ile 60 gün boyunca beslenmişlerdir. Deneme sonunda, en iyi büyüme performansı ve yaşama oranı sarı renkli yem ile beslenen grupta tespit edilmiştir. Sonuç olarak, sarı renkli yem, Mozambik tilapiası larvalarında daha iyi büyüme ve yem alımını ortaya koymuştur.
