Good catch and thanks for the report. Your a better man than me to brave the heat and yeah there is a lot of meat left on those cats.
Check out this video by Jeff Faulkenberry of Endless Season Guide Service. He shows how to fillet a bluecat. There is a bunch of good meat on the belly that a lot of folks through away. Some say its the best meat on the fish. I don't know if the link works (I'm not sure how to do it) but you can copy and paste it or just search Jeff Faulkenberry on utube, How to clean a catfish and not waste any meat.
