Çipura (Sparus aurata L., 1758) larva yetiştiriciliğinde mikrokapsül yemler kullanılarak artemia (Artemia salina L., 1758) kullanımının azaltılması

Bu çalışmada, çipura larvaları 21-35. günler arasında farklı oranda artemia ve mikrokapsül yemler kullanılarak beslenmiş, larvaların bu günler arasındaki gelişme ve yaşama oranları tespit edilerek, artemia kullanım oranlarının azaltılmasına çalışılmıştır. Çalışmada deneme grupları %100 artemia, %25 Mikrokapsül + %75 artemia, %50 mikrokapsül + %50 artemia, %100 mikrokapsül olacak şekilde beslenmişlerdir. Artemia kullanım oranlarının azaltılması üzerine yapılan çalışmada, %25 mikrokapsül + %75 artemia besleme rejimi uygulanan gruptaki yaşama ve gelişme oranlarının kontrol grubu olan artemia grubu ile istatistiki olarak farklılık göstermediği tespit edilmiştir. Bu sonuca göre 21-35. günler arasında mikrokapsül yem kullanılarak, çipura larvası yetiştiriciliğinde yem giderleri içinde büyük bir pay tutan artemia kullanım oranlarının %25 azaltılabileceği, bunun larvaların gelişme ve yaşama oranı üzerinde olumsuz bir etkisi olmadığı tespit edilmiştir.

Reducing artemia (Artemia salina L., 1758) use in the rearing of glithead seabream (Sparus aurata L., 1758) by using microencapsulated feed

In this study, gilthead sea bream larvae were fed by using different concentrations of artemia and microcapsule feeds between the 21st and 35th days, artemia usage ratios were tried to be decreased determining the growth and survival ratios of the larvae between these days. During the study, the test groups were fed by using 100% Artemia, 25% Microcapsule + 75% Artemia, 50% Microcapsule + 50% Artemia and 100% Microcapsule ratios. At the end of the experiment on decreasing artemia usage ratios, it was determined that the growth and survival ratios of the group having 25% Microcapsule + 75% Artemia feeding regime were similar to those of the control artemia group. According to these results, it was concluded that between the 21st and 35th days, artemia usage ratios which is take very important part of the expenses of marine fish larval rearing, could be decreased by 25% using microcapsule feeds, and that it did not have any effect on larval growth and survival.
