14439

Australian red claw crayfish (Cherax quadricarinatus) are one of the cultivated species all around the world. This species has became more popular in recent years with increasing interest in decapod species in freshwater aquariums. In this study, effects of different feeds (flake, stick, granule, Tubifex) on growth and survival of Australian red claw crayfish in aquarium conditions were investigated. The study was carried out in 12 glass aquariums with three replicates. A group of 15 early juveniles (average 0.0165 g of body weight) were placed in each aquarium. The crayfish were fed with ad libitum for 120 days. At the end of the study, the best weight gain was found on granule diet group and the lowest survival rate was found on Tubifex group statistically (P 0.01).
