2.4. Growth
Growth was monitored at 15 day intervals by weighing the fish
from each tank collectively. Growth performance of fingerlings
such as weight gain (%), specific growth rate (SGR), feed conversion
ratio (FCR) and feed efficiency ratio (FER) were calculated based on
the following standard formulae:
Weight gain ð%Þ ¼ ½Final weight Initial weight=Initial weight
100
SGR ð%Þ ¼ ½ln Final weight ln Initial weight=No: of days
100
FCR ¼ Total dry feed intake ðgÞ=Wet weight gain ðgÞ
