4th Workshop on Gonadal Histology of Fishes

 

Book of Abstracts
Final Programme

Organized by FRESH and AFS/MFS

 

16-19 June 2009

El Puerto de Santa María, Cádiz, Spain

 A workshop for researchers working on all aspects of reproduction and gonadal histology of fishes will be held June 16-19, 2009, in El Puerto de Santa María, Cádiz, Spain, at the Fisheries and Aquatic Research Center “El Toruño”. This workshop is organized by the COST Action FA0601 “Fish Reproduction and Fisheries” (FRESH) and the American Fisheries Society (AFS Marine Fisheries Section). This workshop will encompass scientists  working on all aspects of the reproduction of marine teleosts, freshwater teleosts and elasmobranchs from diverse locations, and will include presentations on gonadal histology from a broad selection of fish taxa representing diverse reproductive strategies and geographical ranges. The workshop will build on the successful “Third Workshop on Gonadal Histology of Fishes”, held July 2006 in New Orleans, USA.  The objectives of this workshop are to present a wide range of histological approaches being used to better understand the reproductive dynamics of fishes and to promote discussion of reproductive themes critical to sustainable fisheries within an histological context.  A major consideration of the workshop will be the effects of fecundity, atresia, intersex, and other histological indicators on reproductive potential, and how these histological observations can be used as ecosystem status indicators.

There will be four Symposia sessions, a session for contributed presentations and a poster session.
