Última Características de algunas rayas de la región sudpatagónica OceanDocs Sánchez, M.F.; Mabragaña, E.. Data considered in this paper were obtained during a research cruise carried out on board of RV Dr. E.L. Holmberg from INIDEP (Instituto Nacional de Investigacion y Desarrollo Pesquero) during March-April 2000 in the area between 48°S and 55°S (S Patagonian) region, SW Atlantic. From 61 bottom trawls a total of 355 specimen belonging to 11 skate species were collected. This represents, in number, 1.8 of the total species biomass. All skate species were identified and some biological characteristics for each species analyzed. Abundance was estimated in tons and the distribution area of each species was determined. Total weight and morphometric data by sex were measured total length, disc width and clasper length. Stomach content and macroscopical...

Ano: 2002 URL: http://hdl.handle.net/1834/2426 Clave de identificación de cápsulas de huevos de condrictios del Mar Argentino OceanDocs Mabragaña, E.; Figueroa, D.E.; Scenna, L.B.; Díaz de Astarloa, J.M.; Colonello, J.H.; Massa, A.M.. Twenty eight species of oviparous chondrichthyans were reported on the Argentine Continental Shelf (SW Atlantic). The egg cases laid on the sea bed provide useful information to identify species, eggs laying areas and seasons. Based on the analysis of 155 egg cases corresponding to 21 chondrichthyan species, an illustrated field guide for a correct identification is presented.

Ano: 2009 URL: http://hdl.handle.net/1834/3459 Las rayas del género Psammobatis de la plataforma Argentina: biología y ecología OceanDocs Mabragaña, E.. Las rayas (Rajidae)conforman un grupo de peces cartilaginosos de hábitos bentónicos, presentes en casi todos los mares del mundo. En la plataforma continental argentina (PCA)han sido reconocidas 23 especies de rayas pertenecientes a 7 géneros (Atlántico SO). El género Psammobatis Günther, objeto del presente estudio, es endémico de Sudamérica y está compuesto de 8 especies. Dentro de las rayas de la PCA es el que mayores problemas taxonómicos ha tenido debido a su morfología y diversidad. Las características de historia de vida hacen que este grupo sea muy vulnerable a la explotación pesquera. Hasta cerca de una década atrás, en nuestro país las rayas eran capturadas incidentalmente, siendo descartadas o destinadas a la harina de pescado, pero en los...
