Abstract

An experiment was designed to determine the optimum dietary protein level of a freshwater ornamental fish, Blue streak hap (Labidochromis caeruleus). Four isocaloric fish meal based diets ranging from 30% to 45% in protein were fed to triplicate groups of Blue streak hap for 8 weeks. Fish (initial weight, 0.85 g) were reared in twelve 50 L aquarium with biological filter and controlled temperature (27.5°C), in stocking density of ten fish/aquarium. Results showed that dietary protein level significantly influenced final weight, weight gain and specific growth rate of fish. Maximum growth of fish was observed in the 40% protein diet, although this was not significantly different from the 35% and 45% protein diets (P>0.05). Specific growth rate and feed efficiency increased from 30% to 40% protein, and thereafter decreased for diet 45% protein. There were statistically significantly differences in feed intake among treatments (P<0.05). Fish fed with the highest protein diet had lower percentage daily feed consumption values than those of fish fed with the lowest protein diet. Under the experimental conditions applied, juvenile blue streak hap, L. Caeruleus, appear to require more than 35% dietary protein for optimized growth.

Özet

Bu araştırmada, akvaryum balıklarından sarı prenses (Labidochromis caeruleus) balığının yemdeki optimum protein ihtiyacı incelenmiştir. Üç tekerrürlü olarak yürütülen çalışmada, sarı prenses yavruları, protein oranı %30 ile %45 arasında değişen dört farklı eşit enerji içeriğine sahip yemlerle sekiz hafta süreyle beslenmiştir. Yavru balıklar (0,85 g), su sıcaklığı 27,5°C olan biyolojik filtreli ve 50 L su hacimli 12 adet akvaryuma stok yoğunluğu 10 adet balık/akvaryum olacak şekilde konmuştur. Deneme sonunda elde edilen veriler, yemdeki protein oranının balıkların deneme sonu ağırlığını, ağırlık artışını, spesifik büyüme oranını ve yemden yararlanmayı önemli derecede etkilediğini göstermiştir. Gruplar içerisinde en iyi büyüme %40 protein içeren yemde görülmekle beraber, %35 ve %45 proteinli yemlerle beslenen balıklarla bu grup arasında istatistiksel olarak önemli bir fark yoktur (P>0,05). Spesifik büyüme ve yemden yararlanma oranları %30 proteinden %40 proteinli gruplara doğru artmış ve sonra %45 proteinde düşmüştür. Grupların yem tüketimleri arasında istatistiksel olarak önemli farklılıklar bulunmuştur (P<0,05). En yüksek protein içeriğine sahip yem ile beslenen balıkların günlük yem tüketim yüzdesi, en düşük protein içeriğine sahip yem ile beslenenlere göre daha düşük bulunmuştur. Bu deneme koşullarında, sarı prensesin optimum büyümesi için %35’den daha yüksek oranda proteine ihtiyaç duyduğu görülmüştür.
