Here is a Potomac blue catfish caught over the weekend, across from Georgetown on the VA side. We didn't have a scale with us but I estimate in the 60s, my friend was having a hard time holding it up for a picture. Go to bait is chicken hearts from the H-mart, we were using slip weights and metal leaders with big circle hooks fished about 10-15 yards out. I have been going to the same spot for years and it's really hit or miss, it seems that when you aren't getting any bites at all there is usually a big boy swimming around scaring off all the small fish and when you are getting a bunch of bites there are a bunch of small fish swimming around nibbling at the bait. A friend of mine recently bought a jon boat and we have gone to the Fort Washington area to fish for cats many times but have not had any luck with the really big fish - the old shore spot is tried and true. We generally catch the biggest fish when it gets cold and after a bunch of rain - usually when there is no moon out, but again - it's really hit or miss. Against the wishes of MD DNR (http://dnr2.maryland.gov/fisheries/Pages/catfish.aspx) we let him go, even if we killed him what would we do with him? Eating that sucker is a sure way to get some type of illness, be it PCBs or mercury or whatever, and killing a fish without eating is just doesn't seem right, so he swam away to continue his invasion of the Potomac.
