摘要

The present paper is the continuation of the work by the author published earlier (Durve and Dharma Raja, 1966). Here, seven more anaesthetics in different concentrations have been tried in order to study their effectsudon the behaviour of fingerlings of the mullet Liza fade. This has enabled the author to select suitable anaesthetics—out of thirteen so far experimentedudwith—for fishery work such as transport of live fish, tagging, fin-clipping, weighing, stripping and operating. Earlier work on the subject has been discussed by Durve and Dharma Raja (op.cit.). At the end of the presentudpaper, a general review of all the thirteen anaesthetics is given. Material and methods are the same as mentioned in the earlier paper (Durve and Dharma Raja op. cit.). All experiments were carried out in freshwater and at temperatures ranging from 27 to 28° C.
