Özet
The purpose of this study was to compare the larval growth and digestive enzyme activities of koi carp (Cyprinus carpio var. Koi) larvae fed on Artemia nauplii (AN) and decapsulated cyst (ADC). The experiment was carried out in triplicate and lasted 27 days. Specific growth and survival rates, specific activities of total protease, lipase, amylase and chitinase were examined in experimental groups. At the end of the experiment for group fed with AN total length, weight and SGR were 20.56 +/- 3.23 mm, 0.9 +/- 0.05 g and 2.03 % d(-1), respectively and for group fed with ADC it was 28.16 +/- 4.81 mm, 0.28 +/- 0.16 g and 6.02 d (1) (P<0.05). However, survival rates in the group fed on ADC was 98.88 % while in the group fed on AN was 97.77 % (P>0.05). Besides, there were significant differences on specific enzyme activities (total protease, amylase, chitinase, lipase) (P<0.05). Obtained results suggested that koi larvae fed by ADC presented relatively higher growth parameters.
