I do like a bit of Mullet fishing when I get the chance, I could imagine that working well. One to store in the memory banks for when the opportunity arises !
Brilliant fighters Mullet & a great cross over fish for Coarse anglers to have a dabble for.
My mate used to swear by digging marsh worms for this method, they are stubby little worms about two inches long and a off-yellowish color. He would dig them in the mud by the bank-side before he started. However, I think he said red maggots worked as well. I imagine something like brandlings or small harbour rag-worm might work but he always swore by those marsh worms. he was known as the Mullet Man so he was probably right.
I think this was in the tidal part of the Cuckmere river where he used to go but I don't see why it wouldn't work elsewhere. Give it a go one day, be nice to know if it helped.
