Effects of anaesthetics on the behaviour of mullet\ud fingerlings and the scope of using these in different\ud fishery procedures

By V S Durve and S K Dharmaraja

Abstract

THE use of anaesthetics in fishery work, mainly in the transport of live-fish and also\ud in handling fish for tagging, fin-clipping, weighing and stripping has been recognised\ud by fishery workers everywhere. In live-fish transport, anaesthetics are useful in\ud lowering the metabolic activity of fish, which facilitates the transport of more fish\ud in a given quantity of water for a longer time. It has also been proved that anaesthetics\ud make the otherwise time consuming work of tagging and fin-clipping much\ud easier and also lower the mortality of the fish due to handling. Considerable effort\ud has gone into a search for a proper anaesthetic and its different concentrations to\ud give varying degrees of anaesthesia useful for works from tagging to transport of\ud live-fish
