Use netting to exclude fish-eating birds
A controlled, replicated experiment in 1995-6 at 18 ponds in seven aquaculture facilities in Florida, USA (Avery et al. 1999), found that fish losses from ponds covered in netting were significantly lower (11%) than for uncovered ponds (38%). Main species predating fish were snowy egret Egretta thula, green-backed heron Butorides striatus, tricolored heron E. tricolor and little blue heron E. caerulea.
