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...
متن کاملFeeding behavior and brain acetylcholinesterase activity in bream (Abramis brama L.) as affected by DDVP, an organophosphorus insecticide.
1. Bream (Abramis brama) were exposed to sublethal concentration of organophosphorus insecticide DDVP and the amount of food consumed and brain acetylcholinesterase (AChE) examined in exposed fish. 2. Exposure to DDVP resulted in decreased amount of food consumed and inhibited brain AChE activity. 3. Intraperitoneal injection of the fish with cholinergic drugs, atropine and TMB-4 recovered the ...
