TL;DR: Investigation of growth performance and feeding of this crayfish reared at high densities found no-significant differences among treatments in terms of initial weight, specific growth rate and feed conversion l rate.
Abstract: The acocil C. montezumae is a freshwater crayfish endemic to the Central Plateau of Mexico, but, in recent years, the natural population of this species has diminished considerably. In this work was investigated growth performance and feeding of this crayfish reared at high densities. A random block experimental design with two repetitions and three treatments (77, 154 and 231 crayfish/m2) was carried out. Organisms were fed every third day with 15% of their total biomass of shrimp commercial food with 25% of crude protein, and individual food consumption (IFC) was calculated. Significant differences (ANOVA, P 0.05) among treatments in terms of initial weight, specific growth rate and feed conversion l rate.

TL;DR: In this article, the effect of temperature on the development of Australian crayfish Cherax quadricarinatus juveniles and its thermal preference under laboratory conditions was determined based on the results of growth and survival of C. quadricarisatus.
Abstract: The objective was to determine the effect of temperature on the development of Australian crayfish Cherax quadricarinatus juveniles and its thermal preference under laboratory conditions. The determination of the effect of temperature was made based on the results of growth and survival of juvenile crayfish C. quadricarinatus. The crayfish were cultivated and fed with commercial shrimp pellets for 90 days at four different temperatures (20, 25, 28, and 31 °C). The greatest weight increase and total biomass were obtained at 28 °C and the highest survival (83%) at 25 °C. The thermal preference of crayfish after the assay was also examined in crayfish of each treatment. The thermal preference of crayfish was always between 23 °C and 26 °C.
