This book is about freshwater fish in streams, lakes, reservoirs, and special habitats around the world. It addresses approximately twenty major topics in freshwater fish ecology in a format suitable for use in graduate-level courses. The book focuses on basic ecology and contains much data from fisheries ecology. Dr. Matthews explains the way in which empirical studies, theoretical concepts, and experimental evaluations blend into the current state-of-the-art with respect to each major topic, and provides original data and interpretations on some points as well as new syntheses. Each chapter contains empirical information, a synthesis, and a summary

Turkey shows a notable diversity of habitats, with significant variations in altitude, rainfall, temperature, topography and geological history, which is reflected in its richness of biodiversity. Although there are quite a number of publications on the freshwater fish taxonomy, the data set for endemic freshwater fish as assemblages are poor. According to recent findings, a total of 194 endemic freshwater fish species are now recognised within the political boundaries of Turkey. Endemic fish consist of 47.4% of the Turkish freshwater ichthyofauna (409 species). At the family level, the Cyprinidae comprises the greatest number of endemic species (110 species; 56.7% of the endemic species), followed by the Nemacheilidae (31 species; 16.0%), Cyprinodontidae (18 species; 9.3%), Cobitidae (14 species; 7.2%), Salmonidae (12 species; 6.2%), Gobiidae (7 species; 3.6%), Petromyzontidae (1 species; 0.5%) and Clupeidae (1 species; 0.5%). A total of 143 species (73.71%) are found within a single basin. Considering species diversity, the Konya endorheic basin (64.10%) is the richest in endemics, followed by Burdur (52.38%), Büyük Menderes (40.28%), Van Gölü (38.46%) and Antalya (34.00%). IUCN Red List criteria of 194 endemic species that were evaluated, 18 species (9.3%) are CR, 38 species (19.6%) EN, 17 species (8.8%) VU, 12 species (6.2%) NT, 35 species (18.0%) LC, 11 species (5.7%) DD and 59 species (30.4%) NE. In total, 4 (2.1%) of the species which are endemic to Turkey are already extinct. In this study, the endemic freshwater fish fauna is analysed in terms of their systematic, ecology and distribution pattern for inland basins of Turkey.

The North American freshwater fish fauna is the most diverse and thoroughly researched temperate fish fauna in the world. Ecology of North American Freshwater Fishes is the only textbook to provide advanced undergraduate and graduate students and researchers with an up-to-date and integrated view of the ecological and evolutionary concepts, principles, and processes involved in the formation and maintenance of this fauna. Ecology of North American Freshwater Fishes provides readers with a broad understanding of why specific species and assemblages occur in particular places. Addi.

This publication stands out from many others on fish conservation in that it deals exclusively with freshwater fish of European waters. 34 contributions offer up-to-date reviews on the conservation status of freshwater fish in 10 European countries and research results in genetics, systematics and ecology of more that 20 endangered European fish taxa. Selected examples show the changes in the fish communities of whole catchment areas under human influence in the past decades.Not only scientists in fish biology, but also fishery managers and hydraulic engineers will find new insights into the biology of endangered fish species and basic data in order to elaborate specific conservation measures for the local survival of these taxa

Open workshop at the 18th EAFP Conference, Belfast, UK, 4th September 2017 ; International audience ; Worldwide, viral diseases pose a serious challenge to the fish farming industry and wild fish stocks. In order to prevent the spread of serious fish diseases and to contain and control fish disease outbreaks at a global scale, the World Organisation for Animal Health (OIE) has published relevant data on these fish diseases, both in the Aquatic Animal Health Code (OIE, 2017a), including the OIE listed fish diseases, and in the Manual of Diagnostic Tests for Aquatic Animals (OIE, 2017b), including recommended diagnostic methods. The list of viral OIE notifiable fish diseases currently includes: Epizootic haematopoietic necrosis disease (EHN), Infection with HPR-deleted or HPR0 infectious salmon anaemia virus (ISA), Infection with salmonid alphavirus, causing Pancreas disease (PD) and Sleeping disease (SD), Infectious haematopoietic necrosis (IHN), Koi herpesvirus disease (KHVD), Red sea bream iridoviral disease (RSIVD), Spring viraemia of carp (SVC), and Viral haemorrhagic septicaemia (VHS). At European Union level, Commission Decision 2006/88/EC and Council Implementing Decision 2015/1554/EC provide specific regulation for surveillance and control of listed infectious aquatic diseases in Europe which include the fish viral diseases VHS, IHN, EHN, ISA, and KHVD (European Commission 2006, 2015). Due to the frequent emergence of new serious fish viral diseases, the OIE list of fish viral diseases is regularly being extended. However, apart from these well studied viral diseases, other non-notifiable serious fish viral diseases occur in freshwater fish farming. To focus on these new viral threats for freshwater fish farming, an open workshop was organized at the EAFP Conference at Belfast, 4th September 2017. The workshop consisted of five short lectures and a discussion, involving an audience of 69 international experts, originating from 25 countries, of which 6 outside Europe. The main topics presented included ...
