HPLC-determination of apomorphine in a mormyrid fish, gnathonemus petersii.
Uptake of apomorphine and elimination kinetics in brain and muscle tissue of the weakly electric fish Gnathonemus petersii (Mormyridae) was determined by HPLC. 20 min exposure of the fish to apomorphine in the aquarium water (0.4 mg/l) resulted in a concentration factor of 1.09 for brain and 0.55 for muscle tissue. Elimination from brain tissue can be described with first order kinetics (t1/2 = 2.4 h).
