ANIMAL protection activists say ducks will suffer excruciating deaths when Tasmania kicks off Australia's hunting season tomorrow. 

Against Animal Cruelty Tasmania spokesman Chris Simcox says at least 35,000 ducks will be killed during Tasmania's 33-day hunt and predicts 400,000 will be killed in Victoria when its 49-day season starts on March 21.

Mr Simcox says only a small percentage of ducks are killed outright and there's plenty of time for a great deal of suffering to occur, adding it's an excruciating death.

He says activists dressed in brightly coloured clothing and armed with whistles and horns, will scare as many ducks as possible from Tasmania's Moulting Lagoon tomorrow.

RSPCA Tasmania chief executive Greg Tredinnick says most people want duck hunting banned.
