The construction of the Melbourne Seafood Centre was one of the first project developments for Xerri Pty Ltd.

It's 4am, there isn't even a hint of dawn in the dark sky, and there are already dozens of small trucks lined up on Kensington Road waiting for the Melbourne Seafood Centre to open up.

An unlikely alliance has formed between the Victorian Greens and Melbourne's commercial fishers in opposition to a ban on net fishing in Port Phillip Bay.

"The unintended consequence of this ban is that we're going to see a doubling in the price of local seafood and pressure being put on other Victorian fisheries, such as Corner Inlet [near Wilson's Promontory],"  says Andrew McLaughlin from the Melbourne Seafood Centre.

FISH sellers claim the price of traditional fish and chips will rise after commercial netting licences are phased out in Victoria.
