Anti-duck shooting protesters have dumped 800 dead waterbirds outside of the Victorian Premier's office in Melbourne, carrying on a 31-year tradition.

The Coalition Against Duck Shooting (CADS) placed the bird carcasses on Treasury Place outside of Daniel Andrews' office as a stand against the 'massacre' hunting season.

Birds including rare freckled ducks and blue bills were recovered from hunting grounds and the grisly haul was laid on the ground as a silent protest against the sport.

According to CADS, Monday's annual duck haul was the largest display the group has presented in its 31 years.

'This weekend truly was a massacre. And with the amount of protected species left for dead, Victorian Labor must denounce this cruel so-called sport,' CADS posted to Facebook.

Veteran activist Laurie Levy from the Coalition Against Duck Shooting says he was ordered off wetlands in Kerang on Saturday morning, the opening of the annual duck season.

'For rescuing a wounded bird I had to go into the shallows and I was fined a total of $930 and ordered off the wetland for the whole of the season,' he told AAP.

Among the dead birds were the rare freckled duck and blue bills which were shot dead during the sport

'It was a massacre out there, shooters started shooting 20 minutes before the opening and you had high ranking game management authority there, you had top police people there, and they were all powerless to stop the early morning shoot.'

Mr Levy says the freckled duck and the blue bill had been among the birds slaughtered at the early-morning start to the season.

'It was a bloody disgrace,' he said.

Mr Levy says rescuers, many of whom were 'traumatised' following the shoot, had collected hundreds of carcasses and would use them to stage a protest.

He called on agriculture minister Jaala Pulford to close the wetlands and stop the 'uncontrolled slaughter of native water birds'.

The coalition has posted footage on social media of ducks dropping from the sky at the scene, followed by an emotive plea to the premier to 'end the violence'.

Animal liberation supporters supported Mr Levy on social media, while the Sporting Shooters Association of Australia (Victoria) described him on Twitter as a 'serial pest' who should 'learn to respect the law'.
