Allometric Growth of the Freshwater Crab Potamon algeriense (Bott, 1967) (Decapoda, Brachyura, Potamidae) in Oued Zegzel, a Mountain Stream, in the Northeast of Morocco

Table 1

Results of allometric relationships studied in Potamon algeriense: analyses of covariance (ANCOVA) carried out to test slope and intercept for both sexes that indicate the beginning of maturity in relation to body size. Significance was indicated by an asterisk.
