چکیده
In this study, the effects of three different commercial aquarium feeds were tested on growth performance, molting frequency and carapace coloration red swamp crayfish (Procambarus clarkii) in two size classes (4 5 cm). For purpose, six experimental groups formed according to (S1: Size 1 S2: 2) feed type (BF: bottom fish food, CF: cichlid food CG: crustacean granules) as S1BF, S1CF, S1CG, S2BF, S2CF S2CG, fed with these diets for 12 weeks. The final mean weight (FMW) S1CG was higher than S1BF (P<0.05). total length (FMTL) (FMCL) S2BF lowest No significant differences recorded conversion ratios (FCR), specific rates (SGR) survival (SR) (P>0.05). cheliped injury cannibalism found both classes. frequencies (MMF) S2CG statistically S1CF respectively has highest lightness (L*) value redness (a*) yellowness (b*) values results showed positive all parameters Further studies are needed investigate efficient use species-specific rations species.

The present study was conducted to evaluate the effect of 20 d starvation on growth, survival, histomorphology and ultrastructure changes in the digestive system of juvenile red swamp crayfish (Procambarus clarkii). Juveniles were divided into two groups: a food-deprived group and a control group at 9 day after hatch (DAH). Individuals were sampled at 14, 20, 29 DAH. During the 20 d fasting per...

Crayfish has become one of the most important farmed aquatic species in China due to its excellent disease resistance against bacteria and viruses. However, the antiviral mechanism of crayfish is still not very clear. In the present study, many high-quality sequence reads from crayfish intestine were obtained using Illumina-based transcriptome sequencing. For the normal group (GN), 44,600,142 h...
