Biometric relationships and sex ratio of the crab Callinectes ornatus (Ordway, 1863) (Decapoda, Portunidae) captured as bycatch in the northeast coast of Brazil.

: This study aimed to determine biometric relationships and sex ratio of the Callinectes ornatus Ordway, 1863 captured in the northeast coast from Brazil. Male demonstrated allometric positive growth, and female negative allometric growth. The sex rate was higher values for male (1.65:1).
