One alternative to harvesting spat from 90 Mile Beach is to dangle hairy rope – called Christmas tree rope – in the water near mussel farms.


They’re called Christmas tree ropes because they look a bit like Christmas tree tinsel. They have a central thread with lots of hairy fibres hanging off them, and the mussel seed which is floating in the water finds it and thinks it’s a piece of hairy seaweed and settles in it and attaches to it and sets up home there. That Christmas tree rope is then harvested and hung out on a mussel farm, and the mussels then grow up from there.
