Alterations in the hematological and biochemical parameters and plasma ıon concentrations of common carp, (cyprinus carpio l., 1758) after short term exposure to sub-lethal concentrations of lead

Bu çalışmada kurşunun (Pb) sazan balıkları (Cyprinus carpio L., 1758) için için 96 saatlik LC50 değeri belirlenmiş ve balıklar 96 saat süreyle kurşunun sub-lethal konsantrasyonuna maruz bırakılmıştır. Çalışmada balıkların alyuvar sayısı, hemoglobin ve hematokrit seviyesi, akyuvar sayısı ve lökokrit gibi hematolojik parametrelerinin yanısıra plazma glukoz, laktat ve total protein seviyesi gibi biyokimyasal parametreleri ile birlikte plazma iyon konsantrasyonları da incelenmiş ve kontrol grubu balıklar ile karşılaştırılmıştır. Kurşunun alyuvar sayısı, hemoglobin seviyesi, plazma glukoz ve laktat seviyesi ve plazma iyonları üzerinde önemli bir etkisi olduğu, akyuvar sayısı, lökokrit ve plazma total protein seviyesinin ise değişmediği bulunmuştur.

Kurşunun sub-lethal dozlarına maruz bırakılan sazan balıklarında (cyprinus carpio l., 1758) hematolojik ve biyokimyasal parametreler ve plazma iyon konsantrasyonlarındaki değişimler

In this study the 96 h acute toxicity (LC50) of lead (Pb) for common carp (Cyprinus carpio L., 1758) was investigated and the fish was exposed to sub-lethal concentration of lead for 96 h. The hematological and biochemical parameters (red blood cell count, hemoglobin, hematocrit, white blood cell count and leucocrit) and plasma glucose, lactate and total protein levels and plasma ion concentrations of fish were investigated and compared to control fish. It was found that lead had significant effects on red blood cell count, hemoglobin levels, plasma glucose and lactate levels and plasma ions, while hematocrit, white blood cell count, leuocrit and plasma total protein levels remained unchanged.
