Respiratory Movements

1. An analysis has been made of the pattern of activity of the muscles of the head of the carp, in relation to respiratory movements and pressures generated in the buccal and opercular cavity, during normal respiration and during coughing. 2. From comparison with the results of analyses carried out on other species of fish it is suggested that the respiratory movements of free-swimming teleosts in general conform to the following principles: the lateral expansions and contractions of the buccal and opercular cavities are always synchronous, but the lowering of the floor of the mouth may be synchronous with, or may precede, the lateral expansion. 3. In the carp the levator operculi muscle, although it inserts on the opercular bone, does not participate in the opercular pump but is the abductor of the lower jaw.

By monitoring nitrogen (ammonia and urea) excretion and oxygen consumption in a continuous manner during early development (from 18 to 350 degree days) of common carp, Cyprinus carpio, we noted high rates of ammonia-N excretion (> 100 and > 50 μgN∙h−1∙103 eggs−1) and of oxygen consumption (> 1 and > 2.5 mg∙h−1∙103 eggs−1) at hatching and at the onset of free-swimming stages, respectively. There was a diurnal rhythm in metabolic activity. The relative proportions of urea-N and ammonia-N varied during early development; the mean urea-N excretion rate amounted to 21.9 ± 8.7% of total nitrogen, and there was no significant difference between embryonic and postembryonic stages. Fasted free-swimming larvae exhibited increased metabolic activity just before the onset of massive mortality (> 75 μg N∙h−1∙103 eggs−1 and > 2 mg O2∙h−1∙103 eggs−1 of nitrogen excretion and oxygen consumption, respectively). Ammonia excretion rates increased with temperature, the Q10's being 2.36, 2.33, and 3.53 during embryonic, hatching, and free-swimming stages, respectively.Key words: carp, ontogenesis, nitrogen excretion, ammonia, urea, oxygen consumption, temperature, diurnal rhythm

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.
