Effects of Feeding Frequency on Growth Performance and Molting Cycle of Two Different Size Classes of Red Swamp Crayfish (Procambarus clarkii)

Red swamp crayfish (Procambarus clarkii) is an important crayfish species for both aquaculture and ornamental purposes. In this study, growth performance, survival rate, and molting cycle were evaluated with three feeding frequencies, including every other day (2F1), two (F2) and four times (F4) dai...

In this study, growth performance, survival rate, and molting cycle were evaluated with three feeding frequencies, including every other day (2F1), two (F2) and four times (F4) daily in two different age classes (Size I, 15 days old and Size II, 45 days old). The study was carried out in 50 L glass aquariums with three replicates for 12 weeks. The highest final mean weight (FMW) of Size I group was found in F4 (P<0.05). F2 and F4 groups attained higher final mean weight, final mean total length (FMTL) and final mean carapace length (FMCL) for Size II (P<0.05). Although there were no statistical differences in survival rates (SR) of Size I (P>0.05), the highest SR was recorded in F2 for both size groups. Molting cycle of F2 was the highest for Size I and there was a moderate increase from F2 to F4 in Size II group. In conclusion, F4 for Size I and F2 for Size II groups are recommended. Further feeding studies such as starvation and refeeding cycles, feeding rate, feeding time, etc. are necessary for this important crayfish species.https://dergipark.org.tr/tr/pub/limnofish/issue/41345/424401süs kerevititatlısu dekapodlarıbesin sıklığıyemleme rejimiornamental crayfishfreshwater decapodsmeal frequencyfeeding regime
