Abstract
study was conducted to explore the possibility of using a few locally available
anaesthetics, thiopentone sodium, xylodac, lignocaine and sodium chloride for fish seed
transportation. Application was made by inhalation of anaesthesia where by the drugs, in
aqueous solution, entered the arterial blood during ventilation of the gills. The study revealed
that the mixed seeds of major carp (Labeo rohita, Cirrihinus mrigala and Catla catla) of average
length 2.8 cm could be transported safely in a solution containing thiopentone sodium @15
mg/L of water for more than 30 min without oxygen. In the case of lignocaine, lOml/L gave
the best result with a recovery time of 14 min; whereas, 4ml/L of xylodac was found to be
effective for fish fry with a mean survivability of 90%. The anaesthetics were found to reduce
the activity of the fish fry in the aqueous solutions of the sedative agents. The study indicates
the possibility of utilizing these compounds for short duration fish seed transportation
