Email: [email protected] Abstract. Eight elasmobranch species were reported for the Lagoon of Bizerte, north-eastern Tunisia, central Mediterranean. These species were: Torpedo marmorata, Torpedo torpedo, Dasyatis chrysonota, Dasyatis pastinaca, Dasyatis tortonesei, Gymnura altavela, Myliobatis aquila and Pteromylaeus bovinus. General and local distribution of these eight species are discussed and commented while morphological and biological data are provided. Of the eight species reported, only one could represent a locally established population, the common torpedo Torpedo torpedo, as it was constant inhabitant of this brackish, even acomplishing developement and reporducing there. Two of the three dasyatid species occurring in the Lagoon of Bizerte, could be considered as relatively abundant, Dasyatis chrysonota and D. pastinaca, the third D. tortonesei being rare. Their occurrence could be related with the mussels abundance in the Lagoon of Bizerte, as well as oysters and several gastropod species which constitute their main food. Similar observations could also explain the presence of Gymnura altavela, Myliobatis aquila and Pteromylaeus bovinus in the area in question, which were, by contrast, rather rare. Key words.

  • 1 Morphology and Dynamics of Testicular Gametogenesis in Sympterygia Bonapartii
    Morphology and dynamics of testicular gametogenesis in Sympterygia bonapartii (Chondrichthyes, Rajidae). Ana C. Moya; María C. Díaz Andrade & Elena J. Galíndez Lab. de Citología, Histología y Embriología Animal DBByF, UNS, San Juan 670, 8000, Bahía Blanca, Argentina - INBIOSUR-CONICET. E-mail: [email protected] ABSTRACT. Chondrichthyans constitute a successful group with a long and intricate evolutionary history that makes them highly vulnerable. The smallnose fanskate, Sympterygia bonapartii (MÜLLER & HENLE, 1841) is one of the most disembarked items in commercial harbors in Argentina. In this work, the microscopic architecture of mature male gonads and the dynamics of cysts development are analyzed as an interesting tool for understanding the reproductive biology of this specie. Some biological data related to reproduction are given as well. Two seasons were sampled (fall and spring) and length classes’ frequency distribution and maturity stages frequency distribution are given. LT 50 for males was estimated as 58.01 cm of total length. Testes are symmetric, peer, lobated, with several germinal zones. Inside the gonads, there are many spermatocysts, which contain reproductive cells at the same developmental stage. On the basis of their cytological and microanatomical features, seven maturative degrees of the spermatogenic series were differentiated. Few Leydig cells were recognized at the interstitial tissue between cysts. The microscopic quantitative analysis performed in this work provides a promising tool that may contribute to a better knowledge of the reproductive cycles of this economically and ecologically important species. 1 KEY WORDS: Histology, testis, smallnose fanskate, spermatogenesis. RESUMEN. Morfología y dinámica de la gametogénesis testicular en Sympterygia bonapartii (Chondrichthyes, Rajidae).

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences.

  • Identification Guide to the Deep-Sea Cartilaginous Fishes Of
    Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean FAO. 2015. Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean. FishFinder Programme, by Ebert, D.A. and Mostarda, E., Rome, Italy. Supervision: Merete Tandstad, Jessica Sanders (FAO, Rome) Technical editor: Edoardo Mostarda (FAO, Rome) Colour illustrations, cover and graphic design: Emanuela D’Antoni (FAO, Rome) This guide was prepared under the “FAO Deep–sea Fisheries Programme” thanks to a generous funding from the Government of Norway (Support to the implementation of the International Guidelines on the Management of Deep-Sea Fisheries in the High Seas project) for the purpose of assisting states, institutions, the fishing industry and RFMO/As in the implementation of FAO International Guidelines for the Management of Deep-sea Fisheries in the High Seas. It was developed in close collaboration with the FishFinder Programme of the Marine and Inland Fisheries Branch, Fisheries Department, Food and Agriculture Organization of the United Nations (FAO). The present guide covers the deep–sea Southeastern Atlantic Ocean and that portion of Southwestern Indian Ocean from 18°42’E to 30°00’E (FAO Fishing Area 47). It includes a selection of cartilaginous fish species of major, moderate and minor importance to fisheries as well as those of doubtful or potential use to fisheries. It also covers those little known species that may be of research, educational, and ecological importance. In this region, the deep–sea chondrichthyan fauna is currently represented by 50 shark, 20 batoid and 8 chimaera species. This guide includes full species accounts for 37 shark, 9 batoid and 4 chimaera species selected as being the more difficult to identify and/or commonly caught.

Like these, the review now presented is mainly based on the extensive material assembled during the period 1963 to 1967 by the zoologists carrying out the Biological Brokopondo Research Project, sponsored by the Netherlands Foundation for the Advancement of Research in Surinam and the Nether- lands Antilles (WOSUNA), the Netherlands Foundation for the Advan- cement of Tropical Research (WOTRO), the Rijksmuseum van Natuur- lijke Historie at Leiden, and the Zoölogisch Museum at Amsterdam.
