Molting and growth in relation to form alternation of male spiny-cheek crayfish, Orconectes limosus

Original language description

Form alternation in the male Orconectes limosus was described. Most males underwent 2 molts. A small proportion molted once, without a form alternation. A smaller proportion did not molt at all. Form I gonopods were longer, wider, and more robust than form II gonopods, similar to those of juveniles, in addition to possessing wider protopodites and shorter endopodites. Chelae of form I males were longer and wider than those in form II males. A change of body ratios did not occur in crayfish which moltedonce. Negative allometric growth of chela length (ChL) and width (ChW), and abdominal width was observed after the molt in form II. The body size increased more at the molt to form II, than at the molt back to form I. ChL, ChW, and weight (W) incrementswere 3- (ChL) and 4-times (ChW and W) that of body-size increments and were higher than at the previous molt. Form alternation allows the effective utilization of resources through which males could increase in size and be attractive to f
