Abstract
The molt interval and growth rate of the crayfish P. clarkii were studied during 5 consecutive molts when the eyestalks, legs or uropods were removed. Mortality during the 8-mo. experimental period was 5 of 23 for the untreated crayfish, 12 of 23 for the eyestalkless group, 2 of 23 for the legless group and 2 of 23 for the uropodless group. Compared to the untreated group, the removal of a pair of eyestalks induces precocious molt and acccelerates growth. Removal of 3 pairs of walking legs or a pair of uropods induces precocious molt without any effects on body growth.This publication has 6 references indexed in Scilit:
