It was a long time since I've fished the Serpentine so I thought I'd give it a try for a couple of hours last night. Since I last visited, both of my regular spots have disappeared - a couple of fences have gone up and what spots you can access, are very overgrown.
I had heard there was carp in the river, and have caught the odd cutthroat there in the past (personally I've never caught or seen a carp in there). So I decided to float a worm under a bobber in the hopes of catching either. The river certainly looks like carp water; very still, slow moving and quite 'mucky'.
After a few small nibbles and 20 minutes of waiting, I had a fish on that threw the hook pretty quickly. Didn't know what it was. Then proceeeded to lose my next two hooks due to snags. Finally after about an hour I hooked up and landed my first ever catfish

I thought it was a carp the way the float bobbed up and down and then started a lateral descent into the water.

Still, I'm pretty happy having only seen catfish in pictures until now.
Fished for about another hour, landed one more catfish and had two other hookups that I didn't get to the bank. Generally it was fairly quiet with nothing jumping or splashing.
On the carp front, I did see two biggish (5 or 6 lbs) carp cruising and rolling in the mid river so I know for sure they are there and close to the spot I'm fishing. Next time, I'll probably target them with dough or sweetcorn and see what I can do.
