I cut my teeth on the upper reaches of the bristol channel, 30 years ago was codling aplenty. Mostly fish in the 1lb8oz to 3lb class, but with at least 1 fish landed 6 to 8lb per tide along a particular stretch. 10 codling in a 3 hour session wasn't unusual. Not easy to get an insize codling up there now. Chesil was a totally different beast to what it is now, dogfish were very uncommon! Spurs on the other hand were plentiful and a good size too. I found
cod harder to come by, definitely seems like more
cod about in recent times but the average size was much bigger, normally 5 to 9lb class fish. I'm not sure if it's down to improvement in rods, reels etc or maybe I can cast further nowadays. Plaice were definitely bigger, and the whiting were huge! Averaging nearly 2lb on occasions (probably why the spurs were there!). Going back to the bristol channel, many more school bass about nowadays, there was probably the same numbers around 10 years ago but they were bigger, mostly 4-5lb fish very few schoolie back then. Then whiting have all but vanished, the congers are much smaller and only just seem to be coming back (plenty 20lbers about 20 years ago). What I have noticed in recent times are the decline in numbers of small fish, slips, pins etc.. Thornback Ray numbers no where near what they were and much much smaller average size. The club I used to fish in had a minimum size of 6lb for matches but have had to drop this due to the shrinking size of fish landed.
