Anesthetics are often used to immobilise fishes in research. Many chemicals have been tested in anesthetisation of fishes and each chemical has its own merits and demerits. In the present study, four anesthetics namely, 2-phenoxyethanol, quinaldine, MS-222, and benzocaine were selected to test the efficiency in anesthetisation of common carp Cyprinus carpio. Results indicated that the induction time of the fish exposed in four anesthetic solutions significantly (P < 0.05) decreased with increasing concentration but recovery time was independent to concentration. The effective concentration which produced anesthesia within 3 minutes and allowed recovery within 5 minutes in common carp were 600 mm3/dm3 (2-phenoxyethanol), 6 mg/ dm3 (quinaldine), 50 mg/ dm3 (MS-222), and 50 mg/ dm3 (benzocaine). A brief comparison about the advantages and drawbacks of the four anesthetics are given in Tab. 4.

Anestetyki są często stosowane do unieruchamiania ryb dla przeprowadzenia badań naukowych. Wiele związków chemicznych testowano pod kątem ich przydatności jako anestetyków. Każdy z nich ma jednak swoje strony pozytywne jak i negatywne. W niniejszych badaniach wybrano cztery anestetyki (2-fenoksyetanol, ąuinaldinę, MS-222 i benzokainę) w celu zbadania ich efektywności w anestezji karpia (Cyprinus carpio). Otrzymane wyniki wskazują, że czas indukcji u ryb poddanych działaniu roztworów anestetyków w sposób istotny (P < 0, 05) malał wraz ze wzrostem stężenia, zaś czas „dobudzania" był niezależny od stężenia. Skuteczne stężenia, które pozwalały osiągnąć „efekt usypiający" po 3 minutach i „dobudzenie" po 5 minutach wynosiło u karpia 600 mm3/dm3 w przypadku 2-fenoksyetanolu, 6 mg/dm3 dla quinaldiny, 60 mg/dm3 dla MS-222 oraz 50 mg/dm3 w przypadku benzokainy. Zwięzłe porównanie zalet i wad czterech badanych anestetyków podano w tabeli 4.
