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 ...
Stock Characteristics and Management Insights for Common Carp (Cyprinus carpio) in Anatolia: A Review of Weight-Length Relationships and Condition Factors
(Central Fisheries Research Inst, 2013)
The common carp (Cyprinus carpio) is a species of primary importance for commercial inland fisheries of Anatolia, where it is native to some areas but has become almost ubiquitous due to historical translocations. Yet, ...
Long-term growth patterns in a pond-dwelling population of crucian carp, Carassius carassius: environmental and density-related factors
(Wiley, 2011)
Scale samples from crucian carp, Carassius carassius (L.), collected over a 10-year period from a population in an ornamental pond were used to examine patterns in growth as a function of environmental factors, including ...
DNA barcoding common non-native freshwater fish species in Turkey: Low genetic diversity but high population structuring
(Taylor & Francis Ltd, 2013)
Negative impacts of introduced non-native freshwater species on native species have been increasingly recognized in the world as well as in Turkey. However, there has been relatively little attention on genetic characterization ...
THE BITTERLING-MUSSEL COEVOLUTIONARY RELATIONSHIP IN AREAS OF RECENT AND ANCIENT SYMPATRY
(Wiley-Blackwell, 2010)
Host-parasite relationships are often characterized by the rapid evolution of parasite adaptations to exploit their host, and counteradaptations in the host to avoid the costs imposed by parasitism. Hence, the current ...
Diurnal vertical distribution of zooplankton in a newly formed reservoir (Tahtali Reservoir, Kocaeli): the role of abiotic factors and chlorophyll a
(Tubitak Scientific & Technical Research Council Turkey, 2013)
Although water level fluctuations and related environmental variations occurring within reservoirs have a considerable effect on the zooplankton community, studies on zooplankton dynamics of reservoirs are very limited. ...
Growth of common carp Cyprinus carpio in Anatolia (Turkey), with a comparison to native and invasive areas worldwide
(Wiley, 2015)
Common carp Cyprinus carpio occurs in several non-native areas worldwide, where it is generally regarded as either naturalised or invasive. Anatolia (Turkey) represents a unique region for evaluating common carp growth, ...
The Effects of Salinity, Temperature and Feed Ratio on Growth Performance of European Sea Bass (Dicentrarchus labrax L., 1758) in the Water Obtained Through Reverse Osmosis System and a Natural River
(Zoological Soc Pakistan, 2015)
In the present study, the effects of effluent water with varying salinity levels coming from the river and reverse osmosis device, temperature and different feeding ratios on the growth performance of European sea bass ...
Length-weight and length-length relationships for three endemic cyprinid species of the Aegean region (Turkey) with proposed standard weight equations
(Tubitak Scientific & Technical Research Council Turkey, 2015)
Empirical standard weight equations and length-weight and length-length relationships were estimated for Barbus pergamonensis, Capoeta bergamae, and Ladigesocypris irideus, three endemic cyprinid species of Turkey that are ...
