Vegan /vegetarian fish food

[jjohnwm]

Hmmm. I wasnt aware we were making a distinction between aquaculture and fishkeeping for this debate.

This seems to me very reminiscent of a conversation I had with a local farmer who was trying to raise turkeys for a few years. His birds were "semi-free-range", which according to him meant that they could waddle around their little barnyard but were never more than a couple feet from a food dish. They were the big-ass globular white barnyard turkeys that are so beloved of Butterball cooks. All breeding was done by means of artificial insemination; he didn't breed them, just purchased day-olds and raised them up.

He said that they went from hatchlings to marketable size in 5 months. I had heard that these big fat birds often dropped dead of heart attacks upon achieving maturity, so I asked him about that.

His answer: Who gives a crap? All they need to do is grow like wildfire, and be alive at the five month age to be slaughtered.

He had no idea what might happen if one were allowed to live beyond that, and had no interest in finding out. They might as well have been artichokes or watermelons.

It sometimes seems as though a lot of people on MFK...not taking a shot at you here, Backfromthedead !...view fish the same way.

Ive come to the conclusion that we will have a much harder time getting people to feed their fish a vegetarian feed than we would actually raising the fish on it. Lol.

Never said it couldn’t be done. One could also raise their kids on a diet of hot dogs, french fries, and apple pie - and they would grow, and survive up until a certain point. I already feed veggie based foods, in fact, I had asked the manufacturer to create one for years. IMO he went above and beyond all others. NLS Algaemax. But after a lifetime of successfully feeding and raising some of the more sensitive fish in the hobby, such as Moorish Idol, Rock Beauty, etc, he understands the role that marine proteins and fat play in their survival. It was for that exact reason why he stayed away from veggie based diets for so many years. He was thinking of the fish, and their overall health and longevity, not profit. It was many years before he could source some of the marine algae that he currently uses, hence the change.

No closed mind here.

lol, those are commercial diets, with studies funded by commercial operations. I don’t even have to look at them, none of them will be long term studies. Most commercial studies last weeks, maybe months. Show me one that runs the

Scientists find key to vegetarian diet for fish raised in aquaculture

As warning bells clang about the decline of ocean fisheries and contaminant levels in fish, scientists from the University of Maryland Center for Environmental Science have found the key to raising some marine fish on a vegetarian diet. The study found that cobia—a fast-growing fish well-adapted...

Seems like the people who are serious about researching this are focused on several types of algae as a protein source. And it seems like most researchers are more confident about a "mostly" vegetarian aquafeed than a fully vegan one, but my point is that there are institutions out there who are treating this as a real option for the future of aquaculture.

They made progress with rice hulls and tapioca, , several decades ago. Not sure what your point is? Corn, soybeans, wheat, peas, etc, have all been used for many years. I believe that algae was being trialled 20 or so odd years ago? All in the never ending search for lest costly sources of protein. Less costly, not better, not even ideal. Lots of lower cost ingredients that will get the job done. No argument there. But sounds like OP wants to make his own vegan food, yet doesn’t even understand what amino acids are essential, or at what limit. I have been feeding algae to my fish for many years, but I’m not going to force feed my fish because of my own personal beliefs or ideology.

Nothing against vegans either, I love all women equally.

I dont want to make my own, if there is a commercial vegan food it will be much more ideal! Even if it wont be enough to be 100% of the diet, if theres a 100% vegan food then I'll just need to add the meaty part and can find a way to do it sustainably like from eggs that the chickens from the sancurary are laying and being thrown away or from scrapes...

I dont know if it's legal to do it

Im not trying to make any points about the ol tapioca wafers...

S Savethemall i never once ever gave thought to vegan fish food as ever being something that existed or would. But hey, thanks to you and this thread i feel much more educated on the subject. I think we will only see more and more of the industry committing to sustainable feeds in the future, and this vegan niche will certainly expand accordingly.

Thanks, nice to hear.

Idk if it's ok to do that but I want to use the high traffic of this thread and direct some of it to another in which u kind of need urgent help in,

Whoa whoa whoa if nobodys gonna take pandas seriously here than you most certainly are not getting away with talkin turkey!

But youre right, none of those studies cited whether or not the fish could swim properly or was/wasnt covered in cancerous lesions by the end of it...just growth rate and body mass, the good ol moneymakers.

I just want some of the naysayers from the beginning of this thread to acknowledge that there is at least a jumping off point for this diet, fad, niche, whatever a vegan fish pellet would end up being....i already knew the two old canadians would have plenty to say. Damn you. You all must just sit inside and read fish books all winter long cause the whole of outside is frozen stiff.

You wont catch me feeding my fish a vegan diet. Well, except for that rescue pacu im still looking for, and thats for a good cause..

This thread is like the Earth's biosphere: an intricately linked maze of interdependent elements, each affecting and affected by all the others. You can't isolate one small part and study it separately from the rest. Pull on one thread...

Really? Why is that? Seems a bit judgmental and...closed-minded, perhaps?

Let's work in unison. You get that pacu and start scraping your lawnmower off into its tank. I'm gonna grind up some pandas and try them on my Jelly Cat and my turtle. None of those generic no-name "panda burgers" for my pets either, no panda meal or panda by-products. I'm using whole fresh pandas, complete with hair, toenails, teeth, bones, radio collars...that "whole animal" complete nutrition thing. Bamboo in the stomach contents will supply the vegetable component of the mix.

It's gonna be work, and will take time...but, since it's too cold to go outside...

Not judgement, empathy. I am a ravenous omnivore myself. I think the only "animal abuse" would be denying my fish the pleasure of eating meat. Vegans are loony imo lol.

Dont settle for some cheap chinese pandas either. Only grade AAA sumatra whole panda will ensure your jelly cat is receiving its complete dietary nutritional matrix. Otherwise youre just pissing in the wind which i hear can be life threatening in canada.

Oh gotcha...wish i could help. Im typically a minimalist when it comes to medications and have never tried kanamycin. Best of luck with that.
