We tested the hypothesis that chronic exposure to total heavy metal loads in Cevizdere surface water and Ünye District tap of Ordu Province (Türkiye) may cause a genetic toxic effect erythrocyte cells carp (Cyprinus carpio) individuals. For this purpose, (loid)s contents waters were determined seasonally. It was both caused DNA damage fish, statistically significant when compared control groups (P
It is important to quantify the concentrations of metalloids and heavy metals (metal(oid)s) in drinking water sources tap due contamination by natural processes anthropogenic activities. In this study, genotoxicity (Kacalı River) (Perşembe district) was mainly investigated comet assay. The effect metal(loid)s monitored vivo using erythrocyte cells Cyprinus carpio. eight (aluminium, nickel, cadmium, lead, manganese, iron, copper, zinc) one metalloid (arsenic) were found samples total content...
Asteriscus otolith shapes as well their morphometry and shape contours were investigated in order to identify four allopatric Alburnus species: A. chalcoides (Güldenstädt, 1772) (Ordu), escherichii Steindachner, 1897 (Eskişehir), mossulensis Heckel, 1843 (Tunceli), tarichi 1814) (Van) Turkish inland waters. These compared using the indices (form factor, roundness, circularity, ellipticity, rectangularity aspect ratio), morphological characters [otolith weight (OWE), length (OL), width (OW),...
Morphological features of sagittal otoliths in Pagellus acarne, P. bogaraveo, and erythrinus samples collected from the Aegean Sea were used to assess variability both between species otolith pairs employing scanning electron microscopy (SEM) contour shape analysis. Twenty-one morphological characters compared detail using SEM Twelve these differ are suitable for distinguishing three congeneric species. Wavelet functions six groups. The wavelet obtained analysis showed high antero-dorsal,...
In this third Collective Article, with fisheries-related data from the Mediterranean Sea, we present historical length distribution of Lophius budegassa in catch commercial trawlers Greek seas; length-weight and length-length relationships five flatfish species (Lepidorhombus boscii, L. whiffiagonis, Platichthys flesus, Pegusa lascaris Solea solea) different coastal areas Turkey (Black Sea Eastern Sea); growth settled Polyprion americanus Deltentosteus quadrimaculatus, Capros aper three...
Pagellus acarne is found in coastal waters worldwide and it includes important species of commercial recreational fisheries. In this study, 16 morphometric variables the sagittal otolith, including six characters, shape indices, four ecomorphological indexes, were investigated for first time among P. stocks collected from Aegean Marmara Seas coasts Turkey. Statistically significant differences between right left otolith individuals both (p < 0.05). Similarly, observed on same side The...
The morphology, biometry and shape indices of the left right sagittal otoliths were studied for sharpsnout seabream, Diplodus puntazzo species from Aegean Sea.The shape, sulcus acusticus proximal distal surfaces, anterior posterior regions a total 52 D. analyzed.The morphometric measurements such as weight, length, width, area perimeter recorded each pair seabream.The form factor, roundness, aspect ratio, circularity, rectangularity, ellipticity calculated puntazzo.The otolith width...
This study focuses on the relationships between otolith measurements and total length; shape indices among for three Atherina boyeri populations (Lake Eğirdir, Lake Iznik, Hirfanlı Dam Lake) to determine regional variations of these in Turkey. 356 specimens with 41.0 - 103.6 mm length A. were examined their otoliths extracted measured. Otolith width is strongest indicator although length, width, weight are good indicators fish different populations. The linear relationship was determined...
Bu çalışmada, Marmara Denizi’nin Tekirdağ açıklarında yayılım gösteren P. acarne türünün boy-ağırlık ve boy-boy ilişkileri ile kondisyon faktörü değerlerinin belirlenmesi amaçlanmıştır. 2017 2018 yılları arasında yerel balıkçılarla koordineli bir çalışmanın sonucunda elde edilen toplam 294 balık bireyi incelenmiştir. Balık bireylerinin total boy(TB), çatal boy standart ölçümleri 0,1 cm hassasiyette yapılmıştır. Balıkların ağırlıkları(W) ise g hassasiyetle belirlenmiştir. Yapılan t testi dişi...
Fluctuating asymmetry can cause developmental disorders in fish, and particularly high levels of adversely affect fish life. In this study, the fluctuating otoliths four Alburnus species (A. chalcoides (Güldenstädt, 1772), A. tarichi 1814), escherichii Steindachner, 1897, mossulensis Heckel, 1843) found Turkish inland waters were investigated. A total 160 collected waters. The level was calculated for width length characters asteriscus. species, which examined present divided into classes...
The fish's inner ear consists of three interconnected semicircular canals and otolith organs located in these canals, which are responsible for balance hearing. Abnormalities can affect the vital activities fish. main purpose this study was to determine morphological morphometric characteristics abnormal normal sagittal otoliths four flatfish species (Lepidorhombus boscii, Platichthys flesus, Solea solea, Pegusa lascaris) sampled from seas (Aegean Sea, Mediterranean Black Sea). investigated...
This study was conducted to discriminate five Scorpaena species and populations of each according morphometric characters. A total 1865 fish specimens were collected from the eight locations in four Turkish seas: Antalya, Balıkesir, Çanakkale, Hatay, İzmir, Marmara Ereğlisi, Ordu Şile. In study, 26 traits measured for intra- interspecific discrimination species. The data subjected analysis variance, principal components (PCA) canonical discriminant analysis. As results PCA, 10 S. maderensis...
The purpose of this study is to estimate some population parameters such as length-length and length-weight relationships condition factor Squalius cephalus individuals living in Tabakane Stream (Ordu-Turkey). A total 326 S. were sampled from Stream, located Ünye district the Ordu province, by using an electroshocker. It was determined that mean total, fork standard lengths fish samples 7.58±0.143 cm, 7.06±0.133 6.30±0.121 respectively, their average weight 6.05±0.322 g. relationship species...
In this study, otolith morphology and contour from big-scale sand smelt, Atherina boyeri were analyzed in Lake Egirdir Iznik (natural lakes), Hirfanli Dam (artificial lake). The sixteen morphological characters such as width, depth, shape, sulcus acusticus ostium, cauda, rostrum size-shape, thickness, antirostrum anterior posterior regions, mesial lateral surfaces successfully investigated for three total length groups of A. inhabiting the lakes. Intraspecific variation size, antirostrum,...
Bu calismanin amaci Yalikoy Deresi (Ordu-Turkey)'ndeki bazi balik turlerinin boy-agirlik, boy-boy iliskileri ve kondisyon faktorlerini belirlemektir. Balik ornekleri, Haziran 2013 2014 tarihleri arasinda farkli goz acikliklarina sahip aglar, serpme olta takimi elektrosok cihazi yardimiyla yakalanmistir. calismada, 4 familyaya (Blennidae, Cyprinidae, Gobiidae, Salmonidae) ait 8 tur ( Alburnus chalcoides, Barbus tauricus, Capoeta banarescui, Neogobius fluviatilis, melanostomus, Squalius...
In this study, the length-length and length-weight relationships were investigated for Saurida undosquamis from Eastern Mediterranean Sea (Turkey). All fish sample lengths weights recorded to nearest 0.01 g cm, respectively. According t-test results, there statistically significant differences between sexes in terms of length weight (P&lt;0.05) S. undosquamis; therefore, female male samples separately evaluated current study. The relationship equations calculated as W=0.0023TL3.330;...
