Pan‐continental invasion of Pseudorasbora parva: towards a better understanding of freshwater fish invasions
- R. Gozlan, D. Andreou, J. Britton
- Environmental Science
- 1 December 2010
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.

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 b…

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.
Experimental Evidence from Causal Criteria Analysis for the Effects of Common Carp Cyprinus carpio on Freshwater Ecosystems: A Global Perspective
- L. Vilizzi, A. Tarkan, G. Copp

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 of…
Conversions of Total, Fork and Standard Length Measurements Based on 42 Marine and Freshwater Fish Species (from Turkish Waters)
- Ö. Gaygusuz, Çiğdem Gürsoy, H. Filiz
- Environmental Science
- 1 February 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,…
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.
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 von…
Non-native and translocated freshwater fish species in Turkey
Data is compiled on the introduction and distribution of freshwater fishes in Turkey, both nonnative and translocated, based on historical accounts and recent surveys to discuss the management options available and outline how these can be incorporated into freshwater fish conservation and non-native fish management programmes.
Evidence of threat to European economy and biodiversity following the introduction of an alien pathogen on the fungal–animal boundary
- Didem Ercan, D. Andreou, R. Gozlan
- Environmental Science, BiologyEmerging Microbes and Infections
- 1 January 2015
Evidence that this emerging parasite has now been introduced via Pseudorasbora parva to sea bass farms, an industry that represents over 400 M annually in a Mediterranean region that is already economically vulnerable is provided, and for the first time evidence linking S. destruens to disease and severe declines in international threatened European endemic freshwater fishes is provided.
