hi bert
only ever had a few conger off the boat, however we did have a lad called billy Knowles, from backworth [billy the bouncer] had a one at 44lbs a good 15plus years ago.
we were targeting ling; and it was slack water and one of them rare days were we sat on the wreck for a good 15minutes
it was the slightest of knocks as well.
weve had about 10-12 strap conger from the yellow can at anchor [ around 10lbs]
but that's in 40 years fishing from the boat,
also again 20years ago we anchor for 6hrs on a wreck targeting conger, took loads of ling and cod. but we did mange a couple of conger in the 20lbs region and a 3-4 monkfish [anglerfish 30lbs]
we had 3-4 go's but never bothered to target them anymore after that
a few used to turn up in the prawn trawl around February,
I think they used to move about a little then to do with spawning.
as I think there is definitely a few conger on every wreck but they are timid and probably nocturnal feeders
cheers allan
