Fish foods, big list

How do you know if it's cod then?

Location helps a bit, for example where does it come from, if it's sourced off Alaska it's probably black sable fish, which is technically a cod, sometimes you can tell it isn't cod by the shape of the fish or the flesh, for example I've seen fillets that were obviously to tall and short to be cod of any sort, other times they leave scales on that don't match cod.
Mislabeling of fish is common and doesn't seem to be illegal anywhere, fish sellers will relabel snapper as grouper to fetch higher prices, and pretty much any fish has been labeled whitefish at some point, because few people want to eat fish named (or think about ) wolfeel,goosefish, or monkfish.

Often less desirable fish are relabeled or mixed with "bigname" fish

What about the smell? I find it smells the worst out of all the fish I buy my p's LOL

The ones I get are labeled North Atlantic cod

I try not to smell fish lol, I have a sensitive sense of smell, so I can smell fish houses away

I think it's called meat fraud.

My fish always prefer their vegggies (sguash, yam, potato, kale, etc.) cooked.

I like to give my fish fresh bugs when I can. Are there any bugs to steer clear of? For the most part if it is a crazy warning color I won't try it. I saw Japanese Green Beetle on the list, I've skipped on those.

I'd think stink bugs would be a do not feed.

Hot dogs? Some guy on here fed his red tail catfish hot dogs a lot.

possible... i managed to fish for gar and redtail catfish among other fishes using hot dog in a pay pond

notice that I won't add goldfish or smelt due to them being bad for most species.

Just a couple things I wanted to add. Although certain fish (and it's a very long list of fish species) such as smelt can sometimes have excessive amounts of thiaminase, the workaround to that is simple. Supplement B1 (thiamin) a few times a week. Problem solved. Boyd Vitachem is one such supplement. If one is primarily feeding frozen food from the supermarket then vitamin supplementation should already be part of the feeding regime. This is how public aquariums, zoos, etc, keep their frozen fed fish healthy long term - vitamins & trace minerals are not just a good idea, they are mandatory to anyone feeding these kinds of foods as the main portion of a fishes diet.

My advice when dealing with fresh fish products, buy fresh, freeze for 48 hrs at 0F (-18C) to destroy any potential parasites, and use up within 30 days or so. Freezing will not destroy all micro-organisms, so there is still some risk involved in feeding frozen products, but freezing certainly minimizes those risks. Also note that frozen fish that have been unthawed under refrigeration, should be fed within 24 hrs. (or discarded)


Freezing tends to also increase the concentration of thiaminase in tissue, so the shorter the duration in the freezer, the better. Little is known as to how thiaminase affects various species, and according to various studies the amounts found (even within the same species of fish) tend to vary as well. As previously mentioned most public aquariums tend to supplement to avoid deficiencies. (especially B1, vitamin E, and vitamin C) IMO fish kept in captivity require full vitamin & trace mineral supplementation to some degree or another. This is a non-issue if one is feeding a commercial pellet as the staple, or even stuffing "some" pellets into frozen foods, or supplementing via a commercial pre-soak such as Boyd Vitachem.


I posted the following years ago in another discussion, some good info for anyone feeding insects to their fish.

Also, seeing as some are mentioning plant matter, the vast majority of fish species will do better consuming aquatic plant matter, vs terrestrial based plant matter, the latter typically containing anti-nutritional matter that at the very least should be cooked prior to feeding to at least reduce some of the antinutritional issues found in the raw form. This includes commonly fed items such as peas. Just because it's green, doesn't mean its good for a fish.

Most cod is scrod or haddock if filets are thin...Grouper is the most faked fish out there along with red Snapper which can be many things. Black Cod or Sable is five times as expensive as normal cod and much much fattier. Unlikely to be sub'd......Just my two cents.
