Abstract
ICAR-Central Institute of Fisheries Technology has
developed a hand operated descaling machine of 3
kg capacity for easy and fast removal of scales in
different fishes. This study was to optimize the
loading capacity and duration of operation of hand
operated descaling machine for various fishes. Effect
of loading capacity and duration of operation on
descaling efficiency was analysed using response
surface methodology. Maximum descaling efficiency
of 92.45, 77.24 and 85.78% in sardine,
threadfin bream and tilapia, respectively were
obtained at 2 kg loading and 9 min duration of
operation. Also the highest descaling efficiency of
81.39% was observed at 1 kg loading and 9 min
operation for pearl spot. The obtained optimum
process variables will be helpful for the small scale
fish vendors to use hand operated low cost, efficient
descaling machine for quick and hygienic descaling
process.
