چکیده
background: diazinon is an organophosphate pesticide which is widely used in paddy fields located in northern parts of iran, though it is prohibited to be used in many countries. objectives: the purpose of the present study was to investigate sublethal effects of diazinon on blood parameters of common bream abramis brama. methods: in sublethal toxicity test, fish were exposed to diazinon concentrations of 0.04, 0.36, 0.73 and 1.46 mg/l for 14 days and their hematological parameters including wbcs, white cell differential count, rbcs, hct, hb, mcv, mch and mchc were studied. results: the results of sublethal toxicity indicated that by increase of toxicant concentration a significant decrease was appeared in wbcs, rbcs, hct, hb and mch both after 7 and 14 days (p

متن کاملAttachment ability of a clamp-bearing fish parasite, Diplozoon paradoxum (Monogenea), on gills of the common bream, Abramis brama.
Monogeneans, which are mainly fish ectoparasites, use various types of haptoral (posterior) attachment apparatus to secure their attachment onto their hosts. However, it remains unclear how strongly a monogenean can attach onto its host. In the present study, we aimed for the first time to (1) measure pull-off forces required to detach a pair of clamp-bearing monogeneans, Diplozoon paradoxum, f...
