[cool][#0000ff]When I was learning to fish for trout, as a kid in Idaho, my dad and uncles taught me to let the fish tell me what they were eating. The ritual on many fishing trips was to open up the first few fish and examine the stomach contents (in the days before the fancy suction pumps for checking stomach contents without harming the fish). If two or more fish had been feeding on the same things, then we did what we could to "match the hatch". Of course, in those days, that usually meant using "garden hackle"...worms and grubs...and occasionally minnows.[/#0000ff]

[#0000ff]Over the years I have maintained a gross curiosity about checking the digestive systems of the fish I take home to the fillet board. After slicing off the first fillet (and exposing the internal organs), I usually do at least a quick look at the stomach. If there is a visible lump in the gut, I feel it and/or slice it free of the rest of the innards and check out what the contents might be. Obviously, this has led to some most unpleasant sights and smells, but it has also contributed to my education on what fish really eat, and how different items come into the food chain throughout the year.[/#0000ff]

[#0000ff]I am sure we could have a long thread here, if we simply asked "What is the most unusual thing you have ever found in a fish's (any species) stomach?" I can say that I have been surprised by many of the things I have found, in almost every species. For the most part, fish are opportunists and will chomp on almost anything. I know, I know, there are a lot of fishless fishing trips where the results don't match up with that statement.[/#0000ff]

[#0000ff]I started this post to simply make some observations on some of the things I have observed about Utah catfish in particular...channel cats specifically. First, most of the channel cats I have "CSI'ed" have had mostly the remains of some kind of fish or aquatic invertebrate in them...like crawdads, large larvae, leeches, etc. The larger the cat, the more likely the "leftovers" will be the remains of whole fish, of several inches or more. Channel cats are efficient foragers and often catch and eat live food. Of course, they don't turn down the dead stuff either.[/#0000ff]

[#0000ff]Part of what prompted this post was filleting the 8 cats my wife and I secured for a family fish fry, this past Friday at Lindon Boat Harbor. They had all been dining well, but almost all had something different in their stomachs. I found chunks of cut bait (probably discarded by anglers), whole shiner minnows (also probably former bait bits), remnants of crawdads, some large helgramite larvae (up to 3"), a mostly dissolved white bass (6" -7"), etc. [/#0000ff]

[#0000ff]Probably one of the more interesting items, found in several of the cats, were CARP SCALES. I have seen the same thing many times in the past. Cats pick them up and ingest them, both when the carp lose them during aggressive spawning rituals, and when they find a dead carp on the bottom. They do not have sharp enough teeth to bite into the carcass, but they can strip off and eat some scales. The scales can be digested by the powerful juices in the catfish's system, and are almost pure protein.[/#0000ff]

[#0000ff]One of the cats I took from the "bubbleup" area recently, had a freshly ingested thigh bone of a piece of chicken. My guess is that one of the anglers in the daily bubbleup armada had tossed a KFC bone over the side, after snacking on the flesh. Hey, kitties do like chicken parts (parts is parts). I once witnessed the post mortem on a 15 pound channel from the lower Provo River that had a whole small chicken in it's stomach. Now, THAT was disgusting. The smell was almost enough to make me swear off both chicken and catfish forever. Well...almost.[/#0000ff]

[#0000ff]No matter what you find in a catfish's innards, the fact remains that you will do consistently better when you bait them with something natural to their environment and something as fresh as possible. There ain't much that they will not eat, if they are hungry, but when they are picky they will eat the prime (fresh) stuff first. [/#0000ff]

[#0000ff]A good example is Utah Lake. The channel cats in Utah Lake seem to love a nice bloody chunk of fresh carp meat or sucker meat. They also readily accept white bass parts with gusto. On occasion, a whole minnow works better than anything else. Of course, a plain old crawler is always a good bait, if you can keep it away from the pesky mudders. My point? You can sometimes entice cats with the smelly dough baits favored in the slow murky waters of other parts of the country, but you will consistently do better with the natural foods. In many channel cat waters around the country, where carp are either not present or not prolific, the channels will often not get excited about carp meat when you use it for bait. I think they are genetically patterned in Utah Lake to dine on carpkind...of all sizes, any time of the year.[/#0000ff]
