Larval Development Under Laboratory Conditions of the Xanthid Mud Crab Eurytium limosum (Say, 1818) (Brachyura: Xanthidae) from Georgia

Document Type



Larvae of the xanthid mud crab Eurytium limosum were reared in the laboratory from hatching to first crab stage. Four zoeal stages and one megalops staged were obtained and are described. Complete larval development required about 15 days under culture conditions of 26.0° to 28.0°C and 25 ppt sea water. A long antenna and short antennal exopods consign E. limosum to the Group I xanthid zoeae of Rice (1980). The first stage zoea closely resembles that of Panopeus herbstii and is distinguished by having the dorsal spine strongly recurved at the extremity. Stages 2 to 4 are distinguished from Rhithropanopeus harrisii and Neopanope sayi larvae by having two lateral spines on the telson.
