fat cat

[thebiggerthebetter]

@Knifegill: it is possible that they suffer no harm but I thought, just like with people, they may have fat deposited around their internal organs. IDK. I guess we are thinking aloud. The fat deposits occur for sure with fish fed non-aquatic, fatty foods. That is known. And that fat solidifies at their body temps, as opposed to the mammal/bird etc. body temp.

This made my day! That's just so awesome

Yep. Arapaimag's one was 11 years old and 33" in Sept 2010: http://www.planetcatfish.com/forum/viewtopic.php?f=7&t=30920&hilit=+granulosus

And when people eat f1sh 0il, it oxidizes in our tissues and causes premature aging. Definitely cause to keep warm-blooded animal fats in warm-blooded animals and polyunsaturated fats primarily in cold-blooded animals for the most part. At least now we know it's safe to eat as much saturated fat as is naturally found in foods like eggs and fatty steak. Food sure is complicated!

But obese cichlids always die young, same for so many other fish where fatty deposits are found on the liver and other organs. Is this found in catfish? I do not know. I DO know I've seen an awful lot of very old, very obese catfish doing fine and can't say the same for cichlids and other fish. I suspect cats store fat differently in some way that allows for them to overfeed safely to a degree. Is anything known? I'd love to learn more about this!

Interesting... and new to me. Is not fish oil essential in people's diet? http://en.wikipedia.org/wiki/Fish_oil

IDK if we can lump together cold-water cats and tropical ones, herbivores and carnivores, but I too am eager to hear from someone with knowledge.

I think even in the wild the will constantly searching for food, and perhaps over feed themselves whenever they can.

No, fish oil is definitely not essential. There are already more than enough omega-3 and omega-6 oils in land animals. Not saying NEVER to eat fish, I mean, they're a great food all around. Just like anything humans have decided to chew on, it has its benefits and potential detriments in the long haul.

These are definitely an opportunistic fish. Mine has a slightly rounded belly most of the time but never to the extent here. I think its because of the level of competition for food. Mine only swims at night but will feed during the day if food falls right in front of its mouth.

As for fatty tissue around catfish organs i can say that after dissecting hundreds of catfish from at least 60 different species that i have yet to encounter fatty tissue around the internal organs or in the organ tissue itself. Granted these were not obese fish for their particular species. Would be interesting to dissect particularly chubby fish to see if there's a difference. Fish dont seem to deposit fat stores like mammals or even some reptiles do. Even pictures of. Very massive catfish cut up in markets dont seem to have any or very little fat deposits. All this being said if you were feeding your fish non aquatic meats high in fat what would this do over time to fatty deposits in the fish body. In general fish only ocassionaly take meats of the non aquatic variety. Catfish maybe more so than many fish but this is still only a small percentage of the actual diet. As a note the stomach muscles and high on the back muscles are the only places i have really encountered any significant accumilation of fats on catfish. Even then it was only very slight. It seems they mainly put on muscle tissue versus fat deposits.

Sure. The point being food is scarce in the wild versus a fish tank. So is pigging out. Not saying anything critical, just mulling it over with everyone else.

Good to hear Necro's testimony.
