Reproductive ecology of two cyprinid fishes in an oligotrophic lake near the southern limits of their distribution range
Investigation of the reproductive activities of two dominant fish species in an oligotrophic lake in the northwest of Turkey revealed that spawning of both species in this area started earlier, but spawning temperature and the duration of spawning was approximately the same. Expand
Length–weight relationship of fishes from the Marmara region (NW-Turkey)
Summary The relation between length (L) and weight (W) was estimated for 32 species representing 12 families of fishes from six water resources in the Marmara region, Turkey. The parameter bExpand
Pan‐continental invasion of Pseudorasbora parva: towards a better understanding of freshwater fish invasions
The Pseudorasbora parva invasion has provided quantitative data for the development of 1) early warning systems across different spatial scales; 2) rapid eradication programmes prior to natural spread in open systems and 3) sound risk assessments with emphasis on plasticity of life history traits.

Conversions of Total, Fork and Standard Length Measurements Based on 42 Marine and Freshwater Fish Species (from Turkish Waters)
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,Expand
Risk screening of non‐native freshwater fishes at the frontier between Asia and Europe: first application in Turkey of the fish invasiveness screening kit
The results of the present study indicate that FISK is a useful and viable tool for identifying potentially invasive non-native fishes in Turkey, a country characterized by natural biogeographical frontiers. Expand
Experimental Evidence from Causal Criteria Analysis for the Effects of Common Carp Cyprinus carpio on Freshwater Ecosystems: A Global Perspective
As the most widely distributed freshwater fish worldwide, common carp Cyprinus carpio can be either invasive or “naturalized” in most areas of introduction. This leads to different levels ofExpand
A meta-analysis of latitudinal variations in life-history traits of roach, Rutilus rutilus, over its
The negative relationships the authors have described between (i) fecundity and reproductive lifespan and (ii) fecundyity and egg mass suggest that lower fecundities is compensated for by longer lifespan, while lower FECundity is compensation for by an increased egg mass, when analysed independently of location.

Changes in the fish community of the Ömerli Reservoir (Turkey) following the introduction of non-native gibel carp Carassius gibelio (Bloch, 1782) and other human impacts.
Changes in the relative density of introduced gibel carp Carassius gibelio and native fish species were monitored over four years in the Omerli Reservoir, a temperate drinking-water reservoir in northwestern Turkey. Expand
Use of bone and otolith measures for size-estimation of fish in predator-prey studies
The results suggest that the biometric relationships between fish length and some bones (pharyngeal, opercula, cleithra) are well suited for use in prey-predator studies of all the studied species, but otoliths and the dorsal and anal spines can be used for some fish species only. Expand
Characteristics of a Eurasian cyprinid, Shemaya, Chalcalburnus chalcoides (Güldenstädt, 1772), in a mesotrophic water reservoir
Abstract Age, growth and reproduction of the Shemaya, Chalcalburnus chalcoides, was studied in the Ömerli Reservoir, a large drinking water system located in Istanbul province (Turkey). The vonExpand
