The effects of pollution on haematological parameters of black goby (Gobius niger L.,1758) in Foça and Aliağa bays

Bu çalışmada, .petrol rafinerisinin bulunduğu Aliağa Körfezi'nin ve Foça'nın çeşitli yerlerinden seçilmiş istasyonlardan toplanan kömürcü kaya balıklarından (G. niger} alınan kan örneklerinin, kan parametreleri, kırmızı kan hücreleri (eritrosit), hemoglobin, hematokrit ve ortalama hücresel hacim, ortalama hücresel hemoglobin miktarı ortalama hücresel hemoglobin konsantrasyonu ve trombosit ölçülmüştür. Yapılan mikroskobik çalışmalar sonucu histolojik değişiklikler ortaya çıkarılmıştır. Normal olarak oval ve yassı şekilli nukleuslar değişikliğe uğrayarak fusiform ve küresel şekil almıştır ve hücre zarı dikensi karakter şekline bozulmuştur. Araştırma sırasında suyun kimyasal özelliklerini tespit etmek için su örnekleri de Foça ve Aliağa Körfezleri'nden alınmış ve çözünmüş oksijen, pH, sıcaklık, tuzluluk, ve turbidite gibi fiziko kimyasal parametreler ölçülmüştür. Bu çalışma sonucunda deniz balıklarının kan parametrelerinin çok çeşitli çevresel kirleticiye karşı fizyolojik bir yanıt olarak kullanılabileceği ortaya koyulmaktadır.

Foça ve Aliağa Körfezi'ndeki kirliliğin kömürcü kaya balığı (Gobius niger L.,1758)' nin hematolojik parametreleri üzerine etkileri

In this study, the haematological parameters (Red blood cells, haemoglobin, mean celllular haemoglobin content, mean cellular volume, mean cellular haemoglobin concentration, platelet) of Gobius niger collected from several selected stations in Foça and Aliağa Bays, where a petroleum refinery is located, have been measured. The statistically important differences were found between the measured red blood cells haemoglobin, haematocrit, mean cell volume, mean cell haemoglobin, and mean cellular haemoglobin concentrations obtained from different stations. In the microscopic studies, some histological changes were determined due to environmental pollution. Ovoid shape of the nuclei seen in normal red blood cells hasbeen changed to fusiform and spherical shape and the cell membrane became echinoid..Physico-chemical parameters such as dissolved oxygen, pH, temperature, salinity and turbidity of the water samples taken from Foça and Aliağa Bays were determined. Considering the results obtained in this study of this study, it can be concluded that the changes in the blood parameters of marine fish may be used as a physiological answer to environmental pollution.
