ABSTRACT

This study investigated
the efficacy of eight chemicals administered via bath and cooling to immobilize
the Chinese mitten crab. Isobutyl alcohol, isoflurane, 2-phenoxyethanol, Propiscin,
at the concentration of 20 mLL^-1and MS-222 at the concentration of
1000 mgL^-1had no anaesthetic effect on crabs for 30 min of exposure.
Clove oil was only partially effective at the concentration of 20 mLL^-1.The
best results were obtained when chloroform (1.5 mLL^-1) and diethyl
ether (10 mLL^-1) were used, causing anaesthesia of all crabs within
30 min. The shortest induction time (about 5 min) and rapid recovery (about 1
min) was obtained by cooling. From the tested methods the usage of chloroform
anaesthesia and cooling seem to be most suitable in the Chinese mitten crab.

Key words: anaesthesia, Eriocheir sinensis, immobilizati, mitten crab.
