Standard weight equations of two sub-/tropic nonnative freshwater fish, Clarias gariepinus and Oreochromis niloticus, in the Sakarya River Basin (NW Turkey)
(Tubitak Scientific & Technical Research Council Turkey, 2018)
Clarias gariepinus and Oreochrornis niloticus are two hot-water fish species of African origin that have been recently reported to occur unnaturally in hot-water resources and springs in the Sakarya River Basin (northwestern ...
Trophic Interactions of Two Ponto-Caspian Gobies in the Turkish Part of Their Native Range
(Central Fisheries Research Inst, 2018)
Several Ponto-Caspian gobiids have expanded from their native distribution ranges to Europe and North America. As knowledge on their bio-ecological features in their native range is still limited, the trophic ecology of ...
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 ...
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 ...
Parasites of the common carp Cyprinus carpio L., 1758 (Teleostei: Cyprinidae) from water bodies of Turkey: updated checklist and review for the 1964-2014 period
(Tubitak Scientific & Technical Research Council Turkey, 2015)
A synopsis is provided of the parasites of common carp Cyprinus carpio L. from water bodies of Turkey based on literature data from 1964 to 2014. In total, 45 studies were included in the review and these provided data ...
