The effect of water temperature on number of moults and growth of juvenile signal crayfish Pacifastacus leniusculus Dana
Original language description
The growth rate, frequency of moulting, and intermoult intervals of juvenile Pacifastacus leniusculus were studied under experimental conditions over a period of 3 months. Juveniles were reared individually in small boxes at two different temperatures: 14.31 +/- 0.64 degrees C (cold water) and 20.54 +/- 0.69 degrees C (warm water). Although the average weight and length of consecutive stages were similar at both temperatures, juveniles in warm water attained more moults. Within the age group juveniles achieved a higher length and weight in warm water than in cold water. Three month-old juveniles reached 147 mg and 18.5 mm in cold water at the 6(th) stage of development, and 259 mg and 22.2 mm in warm water at the 8(th) stage. Specific growth rate (SGR)decreased (5.6 and 10.4 for cold and warm water in the first stage, respectively) and reached final values of 1.4 and 1.5 after 3 months of growth. SGR was significantly higher in warm water and showed negative correlations with the numb
