Abstract:
Use of metabisulphite for different species of prawns to prevent them from black discolouration has shown encouraging results. 0.3% metabisulphite was sufficient to control black spot in Penaeus monodon and P. indicus during ice storage for 5 days, whereas a dip in 0.4% metabisulphite for 30 sec prevented black spot in Metapenaeus monoceros for the same period.
