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. -

Early Stages of Fishes in the Western North Atlantic Ocean Volume
ISBN 0-9689167-4-x Early Stages of Fishes in the Western North Atlantic Ocean (Davis Strait, Southern Greenland and Flemish Cap to Cape Hatteras) Volume One Acipenseriformes through Syngnathiformes Michael P. Fahay ii Early Stages of Fishes in the Western North Atlantic Ocean iii Dedication This monograph is dedicated to those highly skilled larval fish illustrators whose talents and efforts have greatly facilitated the study of fish ontogeny. The works of many of those fine illustrators grace these pages. iv Early Stages of Fishes in the Western North Atlantic Ocean v Preface The contents of this monograph are a revision and update of an earlier atlas describing the eggs and larvae of western Atlantic marine fishes occurring between the Scotian Shelf and Cape Hatteras, North Carolina (Fahay, 1983). The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described. Michael Fahay 241 Sabino Road West Bath, Maine 04530 U.S.A. vi Acknowledgements I greatly appreciate the help provided by a number of very knowledgeable friends and colleagues dur- ing the preparation of this monograph. Jon Hare undertook a painstakingly critical review of the entire monograph, corrected omissions, inconsistencies, and errors of fact, and made suggestions which markedly improved its organization and presentation. -

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. -

Artisanal fisheries in the Canary Islands (eastern-central Atlantic): description, analysis of their economic contribution, current threats, and strategic actions for sustainable development. Acta Ichthyol. Piscat. 50 (3): 269–289. Background. Fishing is a primary activity of great importance in the Canaries and has traditionally played an important role in reducing poverty, in job creation, strengthening food security and sovereignty, and increasing the value of its products. This study is needed to analyze fishing contribution in a region strongly based on tourism. Aims were: to update the inventory of fishing techniques, to detail the biodiversity involved, and for the first time to analyze the contribution of the landings. We also identify threats to the activity and draft a plan with strategic actions for its sustainability. Materials and methods. Data on the fisheries and the 2007–2018 series of landings were taken from the regional government website.
