Packardb aDepartment of Biology, Texas A&M University, College Station, TX 77843-3258, USA bDepartment of Wildlife and Fisheries Sciences, Texas A&M University, College Station, TX 77843-2258, USA Received 8 November 2004; received in revised form 25 April 2005; accepted 25 April 2005 Available online 19 July 2005 Abstract Occurrence of 130 species of decapod crustaceans was compared between the continental slope (200–2500 m) and the abyssal plain (2500–3840 m) of the Gulf of Mexico. We compiled records of these species from published literature and from the crustacean catalogue of the Marine Invertebrate Collection of Texas A&M University. Each species was scored as present or absent in each of 10 polygons that were defined by physiographic features of the sea floor. Using cluster analysis, we identified inherent patterns of species richness. A distinct faunal assemblage occurred in the Sigsbee Abyssal Plain. This deep plain was a potential ‘‘coldspot’’ in terms of the number of species in the basin, compared to a ‘‘hotspot’’ in the vicinity of De Soto Canyon. Polygons of the eastern upper slopes (i.e. calcareous substrate of western Florida) contained the most species that were not found elsewhere in the Gulf of Mexico. Usingan inductive approach, we identified the followinghypotheses: (1) most crustacean species of the deep SigsbeeAbyssal Plain occur in oceans world-wide, (2) overall, almost a quarter of the deep sea species in the Gulf of Mexico range from the western Atlantic (south of Cape Hatteras) to the Caribbean, and (3) the Gulf of Mexico is particularly rich in species of Munidopsis (25 species). r 2005 Elsevier Ltd.

Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many resolved. Detailed notes and references are provided where necessary. The constitution of a large number of families and superfamilies is discussed in detail, with the positions of some taxa rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the nomenclature of any large group of decapod crustaceans has been examined in such detail.

Cold seeps fluids provide an additional source of energy for various sulfide- and 27 hydrocarbon-harvesting bacteria, often in symbiosis with invertebrates, attracting a variety of other 28 organisms including crustaceans (e.g., Levin 2005; Vanreusel et al. 2009; Vrijenhoek 2013).

DOI: 10.3856/vol37-issue3-fulltext-21 Short Communication Note on the fisheries and biology of the golden crab (Chaceon fenneri) off the northern coast of Brazil Tiago Barros Carvalho1, Ronaldo Ruy de Oliveira Filho1 & Tito Monteiro da Cruz Lotufo1 1Laboratório de Ecologia Animal, Instituto de Ciências do Mar (LABOMAR) Universidade Federal do Ceará, Av. Abolição 3207, CEP 60165-081, Fortaleza, CE, Brazil ABSTRACT. The occurrence of golden crabs (Chaceon fenneri) off the northern coast of Brazil was first re- ported in 2001. Since then, a few companies and boats have exploited this resource. In the state of Ceará, one company has been fishing for these crabs with a single boat since 2003. The production and fishing effort of this company indicated a decrease in the number of trips and total catches per year. Data collected on one trip in 2006 showed that the CPUE was highest at over 650 m depth. As registered for other geryonid crabs, C. fenneri was segregated by sex along the northern slope of Brazil. Male crabs were significantly larger than fe- males, presenting an isometric relationship between carapace width and length and an allometric relationship between carapace width and body weight.

  • 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.

    4.1.3 Coastal Migratory Pelagics Description and Distribution (from CMP Am 15) The coastal migratory pelagics management unit includes cero (Scomberomous regalis), cobia (Rachycentron canadum), king mackerel (Scomberomous cavalla), Spanish mackerel (Scomberomorus maculatus) and little tunny (Euthynnus alleterattus). The mackerels and tuna in this management unit are often referred to as ―scombrids.‖ The family Scombridae includes tunas, mackerels and bonitos. They are among the most important commercial and sport fishes. The habitat of adults in the coastal pelagic management unit is the coastal waters out to the edge of the continental shelf in the Atlantic Ocean. Within the area, the occurrence of coastal migratory pelagic species is governed by temperature and salinity. All species are seldom found in water temperatures less than 20°C. Salinity preference varies, but these species generally prefer high salinity. The scombrids prefer high salinities, but less than 36 ppt. Salinity preference of little tunny and cobia is not well defined. The larval habitat of all species in the coastal pelagic management unit is the water column. Within the spawning area, eggs and larvae are concentrated in the surface waters. (from PH draft Mackerel Am. 18) King Mackerel King mackerel is a marine pelagic species that is found throughout the Gulf of Mexico and Caribbean Sea and along the western Atlantic from the Gulf of Maine to Brazil and from the shore to 200 meter depths. Adults are known to spawn in areas of low turbidity, with salinity and temperatures of approximately 30 ppt and 27°C, respectively. There are major spawning areas off Louisiana and Texas in the Gulf (McEachran and Finucane 1979); and off the Carolinas, Cape Canaveral, and Miami in the western Atlantic (Wollam 1970; Schekter 1971; Mayo 1973).
