World Aquaculture - March 2012

66 March 2012 The use of growth-adjusted feeding with sinking feed for several weeks after stocking could significantly improve health and survival of fingerlings in a mixed size-class catfish population. However, it might be simpler to routinely feed a fixed percentage of the daily allotment as sinking feed for 8-12 weeks after new fingerlings have been stocked. Higher fingerling survival rates and efficient feeding would reduce costs of production and decrease the time required to grow fingerlings to market size fish.
