I remember living in Temuka as a young fella and they used to dredge Halls Creek out every so many years.
(This was back in the 80’s, in case you were wondering).
But, as soon as the excavator turned up, there were boys from all over town, down there chasing eels all over the banks of the creek, some fell over in the mud and went home in some shocking states.
Some had bags of eels (even school bags had eels in them), I can imagine the reception they got home “Hey Mum, I’ve got some fish for tea!” all covered in mud and stuff.
But, if you can keep eels alive for a few weeks with fresh, running water, they lose their muddy flavour.
Not my favourite food though.
