Artist Unknown LOUISIANA STONE CRABS By Jerald Horst In recent years, a small commercial recreational and fishery has developed for stone crabs in high- salinity bays across Louisiana. Stone crabs began to attract attention in the 1980s, when more of them began appearing in blue crab traps in coastal lakes and bays. In early 1985, LSU biologists conducted a study into the possibility of developing a fishery for them. Before that could occur, however, the great Christmas freeze of 1989 severely reduced the number of stone crabs in Louisiana’s coastal waters. Since then, stone crab numbers have increased to more than before 1989. Modest numbers are landed in some parts of the state for sale in the wholesale trade or for retail sales directly to the public. In some areas, numbers are high enough for recreational crabbers to target. The stone crab found in Louisiana is officially known as the Gulf stone crab, Menippe adina. It is very closely related to the Florida stone crab, Menippe mercenaria, but smaller, with some color differences. The Gulf stone crab has a dark brown body, compared to the tan or gray color of the Florida stone crab, and it doesn’t have bands or stripes around its legs like the Florida stone crab. The ranges of the two species overlap in the area of Apalachee Bay, Florida, where they hybridize. Gulf stone crabs seem to prefer slightly higher salinities than blue crabs, from full strength sea water at 35 parts per thousand (ppt) down to 10 ppt. They seem to prefer areas near or on oyster reefs, rock jetties or debris-cluttered bottoms, where they burrow in the mud for shelter, cold weather refuge and when molting their shell. -

LARVAL DEVELOPMENT OF THE CUBAN STONE CRAB, MENlPPE NODlFRONS (BRACHYURA, XANTHIDAE), UNDER LABORATORY CONDITIONS WITH NOTES ON THE STATUS OF THE FAMILY MENIPPIDAE1 LumInA E. SCO,I'02 ABSTRACT The complete larval development of the Cuban stone crab, Menippc nodifrons, is described and illustrated. Larvae reared in the laboratory passed through a prezoeal, five and uncommonly six zoeal, and one megalopal stage. At 30" C the megalopal stage was attained in 16-17 clays, at 20" C, 28-37 days. The six zoeal stages of M. nodifrons are compared with those of its sympatric congener M. mcrc<'!laria and with the first zoeal stage of the Indo-Pacific species M. rumphii. Larvae ofthe genus Menippe may be distinguished from other xanthid larvae by a combination of morphological features, including lilltennal development (exopodite at least three-fourths the length ofprotopoditel, lack of setae on the basal segment of the second maxillipL'<!al endopodite, and number oflarval stages (Menippe, 5 or 6; most other xanthids, 4). Using Lebour's criteria (emphasizing antenna! development and number of zoeal stages) to determine the primitive or advancL'<! status of decapod larvae, the genus Menippe is more closely related to the phylogentically primitive family Cancriclae than to most of the Xanthidae. The possible reestablishment of the family Menippidae is discussed in view of new larval evidence. The Cuban stone crab, MCllippe llodij'rolls tions of West Africa (Capart 1951; Monod 1956), a Stimpson 1859, is a medium-sized xanthid crab survey of stomatopod and decapod crustaceans of closely allied to the common commercial stone Portuguese Guiana (Vilela ]951), and an ecologi crab, MCllippc I/lcrcenaria (Say 18] 8). -

ABSTRACT RINDONE, RICHARD RYAN. Predator-Prey Dynamics
ABSTRACT RINDONE, RICHARD RYAN. Predator-prey Dynamics between Recently Established Stone Crabs (Menippe spp.) and Oyster Prey (Crassostrea virginica). (Under the direction of David B. Eggleston). Range expansion and population establishment of individual species can have significant impacts on previously established food webs and predator-prey dynamics. The stone crab (Menippe spp.) is found throughout southwestern North Atlantic waters, from North Carolina through the Gulf of Mexico and the Central American Caribbean, and including the Greater Antilles. Recent observations suggest that stone crabs have become better established on certain oyster reefs in North Carolina than in the early 1900’s when they we first observed in NC. To assess the predatory impact of stone crabs on oysters, we (1) quantified stone crab densities on subtidal oyster reefs in Pamlico Sound, NC using scuba diver surveys, and (2) conducted laboratory predation experiments to assess the functional response of stone crabs to varying densities of oysters. We then (3) analyzed previously unpublished functional response data on another important oyster predator, the mud crab Panopeus herbstii. Finally, we (4) compared and contrasted potential predatory impacts of stone, mud and blue crabs (Callinectes sapidus). The functional response data and analyses for stone crabs was consistent with either a type I or II functional response, whereas mud crabs exhibited a type I functional response. Mud crabs, on a m2 basis, inflicted the highest proportional mortality on oysters over a 24 hour period, followed by stone and then blue crabs. Proportional mortality did not vary significantly with oyster size; however, relatively small and large oysters were consumed disproportionately less than medium- sized oysters, likely due to the mechanical inability of stone crabs to handle small oysters, and the inability to crush large oysters. -

In decapods, grooming time budgets, body regions groomed, and grooming appendages are known in several species; however, little data exists on brachyuran crabs. In this study, grooming behaviors of two commercially important crabs were documented (blue crabs: Callinectes sapidus Rathbun, 1896; stone crabs: Menippe mercenaria Say, 1818). These crabs are harvested by fishermen and knowing their grooming behaviors is valuable, as clean crabs are preferred by consumers and the stone crab fishery consequence of removing one cheliped to grooming behaviors is unknown. Crabs were observed individually and agonistically to determine how grooming behaviors vary in the presence of another conspecific. Both species frequently use their maxillipeds and groom, with the gills being cleaned by epipods. Respiratory and sensory structures were groomed frequently in both species. Removal of a grooming appendage resulted in higher fouling levels in the gills, indicating that grooming behaviors do remove fouling. Overall, stone crabs had a larger individual time budget for grooming, but agonistic grooming time budgets were similar. Stone crab chelipeds are used in grooming, especially cleaning the other cheliped. -

Declines among certain economically-important crustacean fisheries (i.e., blue crabs and shrimp) have been reported for both fishery-dependent and fishery-independent data region-wide since 2000. This workshop provided an opportunity for state resource managers and researchers to discuss issues affecting those fisheries and to attempt to identify approaches and resources for addressing the concerns raised. -
Stone Crab Menippe Mercenaria Contributor: Elizabeth Wenner, Ph.D
Stone Crab Menippe mercenaria Contributor: Elizabeth Wenner, Ph.D. DESCRIPTION Taxonomy and Basic Description Photo: Southeastern Regional Taxonomic Center The stone crab is a true crab in the Family Xanthidae. The xanthid family of crabs is commonly called mud crabs. This is a highly diverse family characterized by having a body that is transversely oval or hexagonal and a broad front without rostrum. The last pair of legs is unmodified (Williams 1984). The shell of the stone crab is nearly smooth to the unaided eye and transversely oval with the front broad and notched centrally. The lateral margins of the carapace are divided into four lobes. The pincers are large and heavy, unequal in size and nearly smooth. The inside of the palm has a patch of fine, oblique and parallel striations. The walking legs are stout and hairy toward the end (Williams 1984). The claws of the stone crab are asymmetrical; there is a major or crusher claw and a minor or pincer claw. Only the claw of a stone crab is harvested and a legal size claw has a propodus base measurement of more than 70 mm (2.75 inches) (SCDNR 2005). In South Carolina, only the larger of the two claws may be taken (SCDNR 2005). The color of juveniles is generally dark purplish-blue, often with a white spot occurring on the inner carpus. Juveniles also exhibit three prominent white spots in the form of an inverted triangle on the carapace. Older individuals vary in color from brown to green on the anterior half of the carapace, with tan to cream coloration on the posterior half. -

Commercial Florida Stone Crab Fishing in the Gulf of Mexico States
Commercial Florida Stone Crab Fishing in the Gulf of Mexico States Florida stone crabs (Menippe mercenaria, Say, 1818, Fig. 1) inhabit U.S. waters from North Carolina south to Florida. They live in burrows from the shoreline to 200 feet water depth. They are harvested for their claws primarily with baited traps. The fishery takes place mainly in Florida state waters. Thus, the Florida Fish and Wildlife Conservation Commission manages the fishery. The season runs from October 15 through May 15 (Fig. 2). By Florida law, the larger, immovable part of the claw must measure at least 2¾ inches for harvest. It takes about 3 to 4 years for crabs to reach this size. It is illegal to harvest claws from females that are carrying eggs. Depending on their size, female crabs can produce thousands to millions of eggs in a single spawning season (in Florida waters, April – September). Female stone crabs have a wide, round abdomen, while males have a long, narrow abdomen. Stone crabs regenerate lost claws by molting. It takes approximately three molts (three years) for an adult to regenerate a claw to about 95% of the original claw’s size. However, stone crabs can only regenerate a Figure 1. Extension associate Amanda Jefferson holding a lost claw if the joint between the body and live Florida stone crab. the claw is intact. To forage effectively, crabs missing both claws change their feeding strategy from predator to scavenger. Davis et al. (1978) reported that nearly half of crabs with both claws removed died. Stone crabs are estimated to live 7 to 9 years, but crabs in fished populations probably have a shorter lifespan. -
Larval Growth
LARVAL GROWTH Edited by ADRIAN M.WENNER University of California, Santa Barbara OFFPRINT A.A.BALKEMA/ROTTERDAM/BOSTON DARRYL L.FELDER* / JOEL W.MARTIN** / JOSEPH W.GOY* * Department of Biology, University of Louisiana, Lafayette, USA ** Department of Biological Science, Florida State University, Tallahassee, USA PATTERNS IN EARLY POSTLARVAL DEVELOPMENT OF DECAPODS ABSTRACT Early postlarval stages may differ from larval and adult phases of the life cycle in such characteristics as body size, morphology, molting frequency, growth rate, nutrient require ments, behavior, and habitat. Primarily by way of recent studies, information on these quaUties in early postlarvae has begun to accrue, information which has not been previously summarized. The change in form (metamorphosis) that occurs between larval and postlarval life is pronounced in some decapod groups but subtle in others. However, in almost all the Deca- poda, some ontogenetic changes in locomotion, feeding, and habitat coincide with meta morphosis and early postlarval growth. The postmetamorphic (first postlarval) stage, here in termed the decapodid, is often a particularly modified transitional stage; terms such as glaucothoe, puerulus, and megalopa have been applied to it. The postlarval stages that fol low the decapodid successively approach more closely the adult form. Morphogenesis of skeletal and other superficial features is particularly apparent at each molt, but histogenesis and organogenesis in early postlarvae is appreciable within intermolt periods. Except for the development of primary and secondary sexual organs, postmetamorphic change in internal anatomy is most pronounced in the first several postlarval instars, with the degree of anatomical reorganization and development decreasing in each of the later juvenile molts.
