Just out of curiosity,
Has anyone ever farmed these worms?
Would it be feasible?

The demand for these worms are ridiculous during the summer break when the whitings are on the run. I see people muscling other people out of the way just so they secure a bag for a days fishing and when the bait store runs out they put up a sign "Worms will be available after 5pm when the driver comes back from Stocktons". This from a bait store down in Windang, 15 mins from Wollongong, 3.5 hours from Newcastle. Lucky for me i don't mind using the plastics or the frozen prawns as i am only there for the fun but back when i was a kid looking for worms, all i had to do was to go over to the local beach and pull me a few, guess the local beaches have been over wormed. Same goes for the nippers and them other worms (the red ones) that you pump. The spots that i used to gather bait have been depleted except for a few secret spots, there are not many places left to go and it looks more and more likely that plastics will become the norm.
Good investment if farming is feasible.
