Spawning Frequency of Trachurus Mediterraneus (Carangidae) in the Sea of Marmara
www.trjfas.org ISSN 1303-2712 Turkish Journal of Fisheries and Aquatic Sciences 13: 441-446 (2013) DOI: 10.4194/1303-2712-v13_3_06 Spawning Frequency of Trachurus mediterraneus (Carangidae) in the Sea of Marmara Nazlı Demirel1,*, Ahsen Yüksek1 1 Istanbul University, Institute of Marine Science and Management, 34116, Vefa, Istanbul, Turkey. * Corresponding Author: Tel.: +90.212 4400000; Fax: +90.212 5268433; Received 10.April.2013 E-mail: [email protected] Accepted 28.June.2013 Abstract In this study the spawning frequency of Trachurus mediterraneus was estimated for the first time in the Mediterranean basin. The presence of the late-migratory nucleus stage oocytes and post ovulatory follicles (POFs) in the same ovaries were observed continuously during the sampling period. The daily percentage of spawning females with ovaries containing: late migratory nucleus (MN) stage, POFs (present up to 12-24h from the spawning event) was calculated as 11.7% and 18.6% respectively. The average percentage of females presenting one of the two different states was 15.3% which indicated that Mediterranean horse mackerel had high spawning rates in the Sea of Marmara. Our results indicated that T. mediterraneus is a multiple spawner and females spawn approximately every 6.6 days, therefore 20 times in the spawning period May-August 2009. Keywords: Spawning frequency, post ovulatory follicles, Mediterranean horse mackerel Marmara Denizi’nde Bulunan Trachurus mediterraneus (Carangidae) Türünün Üreme Sıklığı Özet Bu çalışmayla Akdeniz havzasında ilk defa T. mediterraneus türünün üreme sıklığına ilişkin değerlendirme ortaya konmuştur. Örnekleme dönemi boyunca aynı ovaryumda ileri çekirdek göçü evresindeki (ileri ÇG) oositlerle birlikte yumurtlama sonrası foliküllerin (YSF) bir arada bulunduğu gözlenmiştir. -

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. -

Marine Fishes of the Azores: an Annotated Checklist and Bibliography
MARINE FISHES OF THE AZORES: AN ANNOTATED CHECKLIST AND BIBLIOGRAPHY. RICARDO SERRÃO SANTOS, FILIPE MORA PORTEIRO & JOÃO PEDRO BARREIROS SANTOS, RICARDO SERRÃO, FILIPE MORA PORTEIRO & JOÃO PEDRO BARREIROS 1997. Marine fishes of the Azores: An annotated checklist and bibliography. Arquipélago. Life and Marine Sciences Supplement 1: xxiii + 242pp. Ponta Delgada. ISSN 0873-4704. ISBN 972-9340-92-7. A list of the marine fishes of the Azores is presented. The list is based on a review of the literature combined with an examination of selected specimens available from collections of Azorean fishes deposited in museums, including the collection of fish at the Department of Oceanography and Fisheries of the University of the Azores (Horta). Personal information collected over several years is also incorporated. The geographic area considered is the Economic Exclusive Zone of the Azores. The list is organised in Classes, Orders and Families according to Nelson (1994). The scientific names are, for the most part, those used in Fishes of the North-eastern Atlantic and the Mediterranean (FNAM) (Whitehead et al. 1989), and they are organised in alphabetical order within the families. Clofnam numbers (see Hureau & Monod 1979) are included for reference. Information is given if the species is not cited for the Azores in FNAM. Whenever available, vernacular names are presented, both in Portuguese (Azorean names) and in English. Synonyms, misspellings and misidentifications found in the literature in reference to the occurrence of species in the Azores are also quoted. The 460 species listed, belong to 142 families; 12 species are cited for the first time for the Azores. -

Vigo 19 (Pontevedra), Spain. 20 21 Abstract 22 23 An annotated checklist of the marine fishes from Galician waters is presented. The list 24 is based on historical literature records and new revisions. The ichthyofauna list is 25 composed by 397 species very diversified in 2 superclass, 3 class, 35 orders, 139 1 1 families and 288 genus. The order Perciformes is the most diverse one with 37 families, 2 91 genus and 135 species. Gobiidae (19 species) and Sparidae (19 species) are the 3 richest families. Biogeographically, the Lusitanian group includes 203 species (51.1%), 4 followed by 149 species of the Atlantic (37.5%), then 28 of the Boreal (7.1%), and 17 5 of the African (4.3%) groups. We have recognized 41 new records, and 3 other records 6 have been identified as doubtful.
