Feeder frogs?

Nothing is parasite free, whether WC or CB, an "ecologist" should be aware of that. Do you feed crickets? Guess what, they typically carry pinworms. Parasites cannot be eliminated, only managed.

Almost every vertebrate ends up with pinworms. You have pinworms, I have pinworms.. I guarantee that you have transmitted pinworms to your frogs by just picking them up.

Risk is not a dichotomy. Risk is on a sliding scale. It can be reduced and balanced against benefits, never eliminated. The question here is whether or not feeding wild caught frogs to your pets is worth the benefit. On the other hand, nutritionally superb. On the other hand, there are huge parasite concerns no matter what you do, because wild caught frogs carry many different parasites, from pinworms to cestodes, flukes, trematodes, and nematodes nastier than their pinworm cousins. To say nothing of microparasites like protists. Most of which are specialized in parasitizing frogs, and most of which your captive budgetts/pacmans/african bullfrogs have no evolutionary experience with. And no amount of quarantine can fix this, you have to pump them full of anti-parasitic drugs, and that gets expensive very fast when you consider some of them are controlled substances, and you risk ODing your pets, or inducing drug resistance in the parasites that survive to enter your pet.

Juxtaposed against this tradeoff, we have others. Like using lab bred frogs, large insects (hornworms, cockroaches), supplementing with the occasional frozen/thawed quail dangled from forceps, or small captive fish like guppies for aquatic species. Fewer parasite concerns than frogs, and the nutrition is just as good.

So, which is the better choice, and thus the one we are obligated to take when we have a duty of care to an animal we hold captive? Obviously the second.

Lead the charge, let's see how long you can afford to dump money into the pit of breeding $5 frogs. You may or may not be an ecologist, but you sure as hell didn't study economics if you think you can pull that off.

Oh, I did study economics to a far lesser extent, obviously more than you did. If you create a market for captive bred frogs through demand, refusing to pay the lower prices for wild caught animals, breeders will get the message, on a small scale at first. Then growing as retailers get the same message, particularly after a nice little PR campaign. There are a great many species that used to simply be imported, which are now captive bred (and not just frogs). They are more expensive now, but the market persists, because most hobbyists, unless they want a very particular species uncommon in the trade, insist on captive bred specimens. There is definitely a place in the market for healthier, human-acclimated frogs, that do not contribute to the decline of wild populations. Captive breeding is viable for the same reason why there is a market for fair trade coffee/sugar, clothes not made in sweatshops using child labor. People look at something other than the price when making economic choices. Quality and ethical priorities are major priorities for people.

Of course, there are always non-market solutions as well, such as lobbying governments to tighten restrictions on commercial collection of their native wildlife.

Translation: I'm not an ecologist, I'm a college student, but I like to exaggerate my qualifications to appear more credible.

Some species are dietary specialists, and cramming unsuitable food items down their throats for our convenience does not provide the proper nutrition. Keeping a dietary specialist requires a lot of effort and dedication, and the animals deserve nothing less. Dedicated and successful king cobra keepers feed them snakes, not rats. The best savannah monitor owners feed them large numbers of arthropods, not dog food and mice. And I would be willing to bet that froggers who put in the effort to feed dietary specialists like C. cornuta would see greatly increased success compared to those who try to treat them like C. cranwelli and force them to eat unnatural foods. The body composition of a typical mammal, insect, and amphibian are wildly different and it is absurd to say that one can be substituted for the other with no consequences to an animal that has evolved to prey almost solely on one of those choices.

As for green tree frogs, again I say lead the charge. Start breeding them en masse and make the market pay your price. I will eagerly await your results.

Tony,
This guy is an idiot and clearly talking outta his ***. I've fed xenopus to my giant african bullfrog and to my axolotls for years with no issue. He's not an amphibian ecologist anymore than I'm the pope. Once again I'd like to ask users on this forum to personally document a case where THEY have transmitted parasites to their frog by feeding them wild-collected species that mirror their natural diets. Not some so-in-so told me b.s.

I'm not talking someone going out and collecting from an urban lawn, or city dump, but an experienced keeper that is familiar with local amphibians and the conditions they live in.

[jelkins]

And btw. Neither my African Bullfrog nor axolotls has ever become paralyzed from feeding them xenopus that I've raised from eggs purchased from Carolina Biological. I've had my axolotls for over 8 years feeding them a variety of store bought and wild-caught food with no issues. I've had my African Bullfrog for less than a year, but I'm also feeding it a variety of wild-caught and store bought food...No issues.

Yea i fed my frog 4 wild collected toads this toads werent from the city they were caught out in the country where we dont spray pesticides or nothing like that and once i got them home they were feed treated and then two months later at different times they were fed to my frog people should try a varied of food for thee budgetts pac man pixie so your frog can reach itd maxium growth

[jelkins]

Exactly. If you're confident in your source and aren't collecting species that are endangered then you're doing as much as any avid herp keeper can expect.

I collect american toads i tthinking about breeding them where my grandma same place where collect toads from it is a leopard frog there that i wont to feed my frog do those guys have in toxins
