Wow, I was going to ask the same question tonight and someone beet me to it.
I went to Hartlepool today for my Bass trip and the skipper did not turn up (dont know why and his phone is off so he may have lost it.) So i fished Hartlepool docks. First fish a strap conger!! in fact the only fish
This set me thinking about a conversation with Sam Harris a year or more ago about targeting wrecks in southern fashion for conger. It seems from the posts that they are around and I would disagree that ling tactics will catch them on the drift.
The ones I have caught have all been at anchor while skate fishing so it may not be the best comparison. But they take slowly and gently and this is something that is unlikely to happen on the drift except on rare occasions which judging by the numbers quoted is probably the case.
Cheers
Dave
