The collections were made by using two otter-trawls deployed from a shrimp-fishing vessel and occurred monthly during one year. The Fortaleza Bay was sampled in 7 radials of I Ian each. Each environmental factor (temperature, salinity and dissolved oxygen of the bottom water, depth, granulometric composition and organic matter of the sediment), sampled in the middle point of each transect, was correlated with the abundance of 5 groups (adult males, ovigerous females, non-ovigerous adult females, juveniles, and total number of specimens), by Pear son's linear and canonical correlation analyses. The total amount of specimens revealed a positive linear correlation with temperature and very fine sand fraction, and a negative linear correlation with organic material contents. Different association patterns appeared in relation to the abundance of the groups mentioned above, such as depth and granulometry. Ovigerous females were the only group which was associated with the whole set of granulometric frac tions of the sediment. -
Stock Status Report 2016
SKATES – Familia Rajidae About twenty species of the Family Rajidae (Class Chondrichthyes) are distributed in the Treaty area. Commonly known as skates, these species constitute, together with the narrownose smoothhoundand the angular angel shark, the most exploited chondrichthyans of the region. Considering their geographical distribution and the fisheries to which they are subject, two groups can be established: coastal skates and deepwater skates. The coastal skates inhabit the coastal strip of the Treaty area, between 34° and 39° S and from the coast to 50 m depth. It is composed of at least 9 species (Sympterygia bonapartii, S. acuta, Atlantoraja castelnaui, A. cyclophora, Psammobatis bergi, P. extenta, P. rutrum, Rioraja agassizi and Zearaja flavirostris (= Z. chilensis, = Dipturus chilensis). It should be mentioned that the species S. bonapartii and Z. flavirostris have a wide geographic distribution in the maritime areas south of 34° S, including both the coastal region and the deeper one. However, the highest abundances of S. bonapartii occur at depths less than 50 m, while Z. flavirostris, the most important of all the skate from the commercial point of view, is concentrated especially at depths greater than 50 m. A third species, Psammobatis lentiginosa, inhabit in an intermediate region between the two previous or ecotone, close to the 50 m isobath, between 34° and 42° S. In the Treaty area the coastal skates are captured by the fleet Argentine coast that operates on the multispecific fishery called "variado costero" and by the Uruguayan fleet Category B. The others species of the Family Rajidae, which inhabit in the average and external continental shelf of the ZCP, are included in the group deepwater skates. -
Molecular Phylogeny of the Western Atlantic Species of the Genus Portunus (Crustacea, Brachyura, Portunidae)

FELDER2 1Laboratory of Bioecology and Crustacean Systematics, Department of Biology, FFCLRP, University of São Paulo (USP), Ave. Bandeirantes, 3900, CEP 14040-901, Ribeirão Preto, SP (Brazil) 2Department of Biology, Laboratory for Crustacean Research, University of Louisiana at Lafayette, Lafayette, LA 70504-2451, USA Received March 2004; accepted for publication November 2006 The genus Portunus encompasses a comparatively large number of species distributed worldwide in temperate to tropical waters. Although much has been reported about the biology of selected species, taxonomic identification of several species is problematic on the basis of strictly adult morphology. Relationships among species of the genus are also poorly understood, and systematic review of the group is long overdue. Prior to the present study, there had been no comprehensive attempt to resolve taxonomic questions or determine evolutionary relationships within this genus on the basis of molecular genetics. Phylogenetic relationships among 14 putative species of Portunus from the Gulf of Mexico and other waters of the western Atlantic were examined using 16S sequences of the rRNA gene. The result- ant molecularly based phylogeny disagrees in several respects with current morphologically based classification of Portunus from this geographical region. Of the 14 species generally recognized, only 12 appear to be valid. -

Larval Development of the Speckled Swimming Crab, <I>Arenaeus Cribrarius</I> (Decapoda: Brachyura: Portunidae) Reare
BULLETIN OF MARINE SCIENCE, 42(1): 101-132, 1988 LARVAL DEVELOPMENT OF THE SPECKLED SWIMMING CRAB, ARENAEUS CRIBRARIUS (DECAPODA: BRACHYURA: PORTUNIDAE) REARED IN THE LABORATORY Kenneth C. Stuck and Frank M. Truesdale ABSTRACT Eight zoeal stages and a megalopa of the speckled swimming crab, Arenaeus cribrarius, are described and figured from larvae of an ovigerous specimen collected at Hom Island, Mis- sissippi (Gulf of Mexico). Crab stages 1-3 are also briefly described. Larvae were reared at 25°C and 300/00salinity; some individuals completed zoeal development in 30 days,and reached crab I, 13 days later. Zoea I characters of A. cribrarius are compared with those of seven other species of shallow water Gulf Portuninae, from larvae reared by the authors, and from the literature. Antennal and telson features are important in distinguishing among zoeae I ofGulfPortuninae. Characters ofzoeae II-VIII and the megalopa of A. cribrarius and those of corresponding stages of Callinecles sapidus, C. similis. and PorlUnus spinicarpus from the literature are compared. In zoeae III and VI, setation of maxillar basal and coxal endites is a distinguishing feature among A. cribrarius, C. sapidus, C. similis, and P. spinicarpus, and in zoea V, maxillular basal and coxal endite setation distinguish each. Antennular aesthetasc formula distinguishes each species having a zoea VIII, and in all zoeal stages this feature distinguishes A. cribrarius from the others. Zoeae IV and VII of C. sapidus, C. similis and P. spinicarpus can be separated by setation of maxillular basal and coxal endites, and in zoea II this same feature distinguishes P. spinicarpus from C. -
Revisión Del Estatus Taxonómico De Los Batomorphii Fósiles De La Cuenca Limón Sur, Costa Rica Y Descripción De Una Nueva Especie De Dasyatidae
Revista Geológica de América Central, 65, 1-27, 2021 doi: 10.15517/rgac.v0i65.46685 ISSN: 0256-7024 Revisión del estatus taxonómico de los Batomorphii fósiles de la cuenca Limón Sur, Costa Rica y descripción de una nueva especie de Dasyatidae Review of the taxonomic status of fossil Batomorphii from Southern Limon Basin, Costa Rica and description of a new species of Dasyatidae César A. Laurito1* y Ana L. Valerio2 1Instituto Nacional de Aprendizaje (INA), San José, Costa Rica 2Museo Nacional de Costa Rica, Departamento de Historia Natural, San José, Costa Rica *Autor para contacto: [email protected] (Recibido: 16/12/2020; aceptado 27/01/2021) ABSTRACT: A taxonomic review of the rays [Batoidea] faunal assemblage from the Locality of Alto Guayacán, initially described by Laurito (1999), was made, same that was recovered from sediments of the Uscari Formation. The reason for making such revision is the remarkable advance in the knowledge of the dentition and the phylogenetic relationships of the recent and fossil rays. This is complemented by the multiple investigations on fossil Chondrichthyes from southern Central America and the Caribbean that have undoubtedly revolutionized the fossil record of the region. Many of the new species, then described for the Southern Limón Basin, have been validated and recognized by the scientific community and registered in other locations. However, it was necessary to review some of the previous determinations, in order to have an updated taxonomic record. Keywords: Batomorphii; Rajiformes; Myliobatiformes; Uscari Formation; Alto Guayacán. RESUMEN: Se procedió a hacer una revisión taxonómica de la fauna de rayas [Batoidea], descritas inicialmente por Laurito (1999) para la Localidad de Alto Guayacán, misma que fue recuperada de sedimentos de la Formación Uscari. -

In this study, we estimated the size at onset of maturity (carapace width, CW50) and analyzed the relative growth of some body parts and the heterochely of the mud crab Hexapanopeus paulensis. A total of 800 crabs were collected, from January 1998 to December 1999, on the southeastern coast of Brazil. Each specimen was sexed and measured. CW50 was estimated to be 6.7 mm in males and 6.3 mm in females. Carapace length growth was negatively allometric in both sexes. Cheliped length and height was positively allometric for both males and females. Gonopod growth was isometric (b = 1) and negatively allometric (b < 1) in both juvenile and adult males, respectively. Abdomen relative growth was positively allometric (b > 1) for both juvenile and adult females. -
