Virile crayfish displayed similar male:female ratios (Figure 3)
of 0.97 in 2005 and 1.17 in 2006 (chi-square,
P>0.5). The relationship between virile crayfish
CL and mass (n=510), M = 0.00014 CL3.23
(where M equals wet mass in g and CL equals
carapace length in mm), had a coefficient of
determination of 0.99.
