Çanakkale Boğazı'ndan Yakalanan Kolyoz’un (Scomber japonicus Houttuyn, 1782) Biyokimyasal ve Hematolojik Karakteristikleri Üzerine Anisakis pegreffii (Nematoda: Anisakidae)’nin Etkisi

Chub mackerel (Scomber japonicus Houttuyn, 1782) were obtained from the commercial fishermen in Çanakkale, Turkey, July, 2017. We examined a total of 40 fish (20 non-infested and 20 infested) assessed biometric indices, haematological parameters serum biochemical variables. The hepatosomatic index gonadosomatic infested chub lower than those fish. Blood haematocrit ratio haemoglobin concentration naturally parasite-infested significantly However, white blood cell counts higher healthy ones. Serum protein, globulin, glucose, cholesterol, triglyceride, urea, chlorine iron levels Moreover, lactate dehydrogenase, aspartate aminotransferase, alkaline phosphatase alanine aminotransferase activities Therefore, observed variations parameters, variables indices influenced by parasite, A. pegreffii, may potentially increase sensitivity mackerel, Scomber japonicus, to diseases environmental conditions.
