The ecology of freshwater bivalves in the Lake Sapanca basin, Turkey
(Tubitak Scientific & Technical Research Council Turkey, 2013)
Despite the ecological importance and globally threatened status of freshwater bivalves, the freshwater mussel fauna of Turkey has hitherto received little attention. The aim of this study was to describe the ecology of ...
Development of empirical standard weight equation for Pursak chub Squalius pursakensis, an endemic cyprinid species of Northwest Anatolia
(Tubitak Scientific & Technical Research Council Turkey, 2014)
Indices of condition enable the evaluation of the well-being of fish, with the assumption that heavier fish of a given length are in a better condition. Relative weight (W-r) is one of these indices; it is calculated by ...
Assessing the potential impact of nonnative fish on native fish by relative condition
(Tubitak Scientific & Technical Research Council Turkey, 2013)
Nonnative species (NNS) pose one of the most common threats to the conservation of biodiversity. Given the difficulty in measuring and documenting the specific impacts of introduced species on native species, indices of ...
Invasion of freshwater bodies in the Marmara region (northwestern Turkey) by nonnative gibel carp, Carassius gibelio (Bloch, 1782)
(Tubitak Scientific & Technical Research Council Turkey, 2011)
The aim of this study was to learn the invasion speed and sex ratio, which would be indicative of invasive character, of a nonnative fish species, gibel carp, by reporting its new localities in the Marmara region of ...
The Diel Changes in Feeding Activity, Microhabitat Preferences and Abundance of Two Freshwater Fish Species in Small Temperate Streams (Omerli, Istanbul)
(Foundation Environmental Protection & Research-Fepr, 2010)
We examined the abundance, food and microhabitat use of Proterorhinus marmoratus (Gobiidae) and Cobitis vardarensis (Cobitidae) during both day and night in two small temperate streams of the Black Sea region (North-West ...
Conversions of total, fork and standard length measurements based on 42 marine and freshwater fish species (from Turkish water)
(2006)
Relationships between total (TL), fork (FL) and standard (SL) lengths belonging 19 families from Aegean and Marmara coast of Turkey were presented for 42 fish species. The relationships between TL, FL and SL were all linear ...

This study was undertaken monthly between September 2011 and October 2012 at 10 stations in Hisarö nü , Marmaris, and Fethiye bays of Muğla Province with the aim of examining spatiotemporal patterns of distribution, ...
Improving the ecological understanding of species complexes: the case of piscivory and protracted spawning in the carp gudgeon group Hypseleotris spp. (Eleotridae, Teleostei)
(Tubitak Scientific & Technical Research Council Turkey, 2016)
Species complexes are a common occurrence in freshwater fish assemblages and may often pose a challenge to the understanding of their ecology. A typical case is the 'cryptic' carp gudgeon group Hypseleotris spp. in ...
Stocking of Common Carp (Cyprinus carpio) into Some Newly-Established Reservoirs of North-West Anatolia May Enhance the Spread of Non-Native Fish
(Central Fisheries Research Inst, 2015)
Stocking of water bodies with non-native fish species for fisheries enhancement is a common practice worldwide. However, overall limited benefits in terms of revenues for local communities have so far been reported in some ...
