Abstract

Marking with the use of biological stain, Trypan blue, as an aid in determining the
mark retention period, mark recapture technique and the behaviour of the prawns in
general, has been conducted on the freshwater prawn Macrobrachium malcolmsonii of
River Godavari.
The period February—March has been found to be the most suitable period for
marking prawns in the river. The chief observations from the study are: (1) occurrence
of recaptures close to the release spot and recoveries from cast net indicating shoreward
movement to shallow waters, (2) recovery of predominant numbers within a week after
marking and (3) absence of any homogenous trend in the pattern of migration among
the prawns marked
