Stimulation of antioxidant enzymes levels in carp (Cyprinus carpio L.) infected by Ptychobothrium sp. (Cestoda)

1. The anatomy of the upper and lower jaws of the carp, together with the associated maxillaris and mandibularis muscles of the adductor mandibulae complex, is described. 2. From the electromyograms of the adductor mandibulae muscles, recorded simultaneously with a 16 mm film of the mouth movements in a free-swimming carp, the muscle coordination of the diverse mouth movements during feeding has been studied. 3. The interpretation of the results has been verified by electrical stimulation of the muscles, in different combinations, in a fish in which spontaneous movements were abolished by heavy anaesthesia.

Stimulation Of

Electrical stimulation of an epibranchial vagal ganglion, which innervates the gill region, had a marked influence on the respiratory rhythm of the carp Cyprinus carpio. Vagal input could initiate ventilation in fish displaying intermittent respiration. In fish breathing steadily, vagal stimuli could reset the respiratory rhythm by modifying the existing breathing cycle. An increase of stimulus intensity evoked a cough-like movement, thus delaying the onset of following cycles. Rhythmic stimulation, at intervals not more than 10° longer or shorter than the breathing cycle period, could entrain the respiratory rhythm in a one-toone ratio. Larger differences between the stimulation interval and the period of the breathing cycle resulted in either a cyclic modification of the respiratory cycle period or entrainment patterns with coupling ratios of 2:1 or 2:3. Coughing decreased in frequency or even stopped during rhythmic vagal stimulation.
