Mortality associated with declawing stone crabs, Menippe mercenaria. South Florida Research Center.

Bycatch was dominated by blue crab (Callinectes sapidus) and Florida stone crab (Menippe mercenaria) and included 5 diamondback terrapin (Malaclemys terrapin) and 1 clapper rail (Rallus crepitans).

Some species of this genus are used as a fishery resource; for instance, Menippe mercenaria (Say, 1818) and Menippe adina Williams & Felder, 1986, are exploited in the southeastern of the United States (Gerhart & Bert, 2008).

Differing mostly in color, the Florida version (Menippe mercenaria) looks tan while the Gulf version (Menippe adina) has a dark, chocolate tint.

(1979 citado por Restrepo 1992) estimaron que en la pesqueria del cangrejo Menippe mercenaria, de Florida, la tasa de sobrevivencia alcanza hasta un 50% como consecuencia del tiempo y condiciones en que los animales son mantenidos a bordo antes de ser devueltos al mar, asi como con la magnitud del dano causado al cangrejo durante el desprendimiento de la quela.

Major predators on the hard clam at the study site are three crabs (the blue crab Callinectes sapidus, the stone crab Menippe mercenaria, and the mud crab Panopeus herbstii), three whelks (Busycon carica, B.

(1996) report fracture strength in three-point bending of 109 MN [m.sup.-2] in the black cuticle of the claw tips and 32 MN [m.sup.-2] (n = 10) in the lighter-colored cuticle of the manus in the stone crab (Menippe mercenaria).

Based on laboratory trials, mortality in category 3 was attributed to crabs (mainly the blue crab Callinectes sapidus, the stone crab Menippe mercenaria Say, and the mud crab Panopeus herbstii H.

Geographic variation, population biology, and hybridization in Menippe mercenaria and evolution in the genus Menippe in the southwestern North Atlantic Ocean.

In marine waters off the southeastern United States, the two common Menippe species (Menippe mercenaria and Menippe adina) hybridize in two distinct areas (Bert 1986).
