Balıklarda Toksikopatolojik Lezyonlar I

Öz

Balıklarda kirleticilerin etkilerinin belirlenmesinde canlı ağırlık artışı, hepatosomatik indeks, yaşama gücü, yüzme performansı, hematolojik ve kan biyokimyası gibi parametrelerden yararlanılır. Bu parametrelerde ortaya çıkan normalden sapmalar, denenen kimyasalın olumsuz etkisi olarak değerlendirilir. Son yıllarda yapılan çalışmalarda, bu parametrelere ilaveten makroskobik ve mikroskobik patolojik bulgularda eklenmiştir. Hücre, doku ve organın normal yapısından sergilediği farklılıklar uygun metotlar ile belirlenerek kirleticilerin etkileri rapor edilmektedir. Bu derlemede çok sayıda araştırıcının farklı balık türlerinde farklı kimyasalları deneyerek ortaya koydukları lezyonlar farklı organlara göre irdelenmeye çalışılmıştır. İlk bölümde karaciğer, dalak, böbrek ve sindirim sistemindeki toksikopatolojik lezyonlar konu edilmiştir.
