First application in Turkey of the European Non-native Species in Aquaculture Risk Analysis Scheme to evaluate the farmed non-native fish, striped catfish Pangasianodon hypophthalmus
(Wiley, 2020)
The European Non-native Species in Aquaculture Risk Analysis Scheme (ENSARS) was used to assess one of the most popular aquaculture species in the world, the striped catfish Pangasianodon hypophthalmus (Sauvage, 1878), in ...
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 ...
Circumstantial evidence of gibel carp, Carassius gibelio, reproductive competition exerted on native fish species in a mesotrophic reservoir
(Wiley-Blackwell, 2012)
Gibel carp, Carassius gibelio (Bloch), impacts on native fish species have been reported but little studied despite a long history of introductions in Europe. This species is able to reproduce gynogenetically, which involves ...
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 ...
Occurrence of Non-Native Fishes in a Small Man-Made Lake (Lake Ula, Mugla): Past, Present, Future Perspectives
(Central Fisheries Research Inst, 2011)
Changes in fish fauna, fish conditions and some physico-chemical features of water of Lake Ula which was established for irrigation purposes and subjected to introduction of non-native fishes were investigated. Six different ...
Growth and Life History Traits of a Highly Exploited Population of Non-Native Gibel carp, Carassius gibelio from a Large Eutrophic Lake (Lake Uluabat, NW Turkey): is Reproduction the Key Factor for Establishment Success?
(Central Fisheries Research Inst, 2012)
To assess establishment success of a heavily exploited population of non-native gibel carp Carassius gibelio, biological traits and population structure of the species from a large eutrophic lake (Lake Uluabat, Turkey) ...
Growth and reproduction of threatened native crucian carp Carassius carassius in small ponds of Epping Forest, south-east England
(Wiley, 2009)
1. The crucian carp Carassius carassius is a species of cyprinid fish native to south-east England, but few studies exist on its growth and reproduction in England, and the species is threatened by introductions of its ...
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 ...
