Besides traditional methods based on morphological characters, electrophoretic such as SDS-PAGE are preferred by taxonomists to make the right decision in species identification process. In addition, effect of environmental factors, pH, salinity, heat, and temperature protein profiles essential various studies. this study, we aimed determine degree relationship some fish species, Squalius lepid...

The nematode Anguillicola crassus appeared in Europe about 15 yr ago, and has subsequently become recognised as a cause of major pathological lesions in the swimbladder of the European eel Anguilla anguilla. The radiographic method reported in this paper showed be a useful complement to diagnostic methods that have so far been based exclusively on fish dissection. Using this method, the infecti...

The effect of Anguillicola crassus, Pseudodactylogyrus bini and Pseudodactylogyrus anguillae infection on the behaviour of downstream migrating adult European eels Anguilla anguilla as they encountered accelerating water velocity, common at engineered structures where flow is constricted (e.g. weirs and bypass systems), was evaluated in an experimental flume. The probability of reacting to, and...

The aim of this study was to examine the effects of salinity on the survival and growth of a freshwater mussel Unio crassus, from a Mediterranean stream (Sarıçay Stream) in south-west Anatolia, Turkey, which has highly variable environmental conditions and a salinity gradient. A total of 250 similarly-sized U. crassus were collected from a stream in the species’ native range and transferred in ...

Bu çalışmada, Konya Kapalı Havzası'nın en büyük sulak alanlarından birisi olan Akgöl-Ereğli Sazlıkları’nda ilk bilimsel kayıtların verildiği l925’ten günümüze kadar balık faunasındaki değişim irdelenmiştir. 1980’1i yılların başında yaklaşık 10 m derinlikte Akgöl, 1984’de İvriz Barajı'nın yapımından sonraki 5-6 yıl içinde hızla sığlaşmış; günümüzde tamamen kurumasının önüne geçmek için yapay bir...
