As it turns out, after a little bit of googling, that this vegetarian fish idea is not as far out there as most of the members here seem to think. Lot of "animal abusers" out there these days i guess...

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.
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...
Sustainable Aquafeed
The global aquafeed production is expected to grow by 33% to 101.3 million tonnes by 2025 from the current (2015) estimate of 73 million tonnes, closely aligning with the targeted world aquaculture production of 101.8 million tonnes. Aquafeed industry mostly depends...

The Key to Sustainable Fish Farming? Vegetarian Fish | KQED
World demand for seafood is rising, but many of the world’s oceans are already overfished. Now scientists are creating vegetarian diets for species like trout, which may lessen the strain on over-fished oceans.
Evaluation of microalgae as vegetarian source of dietary polyunsaturated fatty acids under autotrophic growth conditions - Journal of Food Science and Technology
Twelve indigenous microalgae, comprising of three fresh water and nine marine strains, were evaluated for their potential as source of dietary polyunsaturated fatty acids (PUFAs) under autotrophic growth conditions. The microalgal lipids showed higher content of omega-3 PUFAs as reflected in...

McFarland Springs Trout
The Most Healthy and Sustainable Fish in the World. Not all farmed fish are alike and none meet the high standards we set for McFarland Springs Trout. Our trout are the only fish in the world commercially raised on a 100% vegetarian non-GMO diet. The result is superior nutrition, flavor and...

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 lifetime of even a single tropical species, let alone the hundreds of different species hobbyists keep. All I have to do is look in my tanks to make my determination.
Yes, and have been for decades - due to the rising cost of raw ingredients from animal sources. It’s a cost saving adventure that has nothing to do with the betterment of fish keeping.
Hmmm. I wasnt aware we were making a distinction between aquaculture and fishkeeping for this debate.
Vegan body builders were a poor example.
Pandas were a poor example.
And now apparently, other fish are a poor example.
@RD with respect, what credible research is not funded by commercial operations these days? Please dont tell me public universities or the government or even non profits who by and large are just as corrupt and commercialized as any corporation. If anything i am encouraged that this research is suggesting profitability--how else will it ever get implemented?
I know your contributions and wisdom on the topic here, but how long have you been out of the biz, man? Is it possible youre set in your ways? Cant see anything new as viable?

Yes, decades...i guess you answered your own query about the studies lasting the lifetime of a tropical fish...
But it seems to me theyre finally making progress, finding some viability, and if it does indeed save money than it will inevitably spread to ornamental fishkeeping no matter how loud we scream "abuse!"
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.

Obviously, one has to. Or are we going to compare a fish that will grow and seemingly thrive on a diet of rice hulls and corn such as the Nile Tilapia (in one of your links above) to a Moorish Idol, kept in captivity? Large scale commercial farms live and die by their feed conversion ratios, everything else is secondary. Hobbyists don’t typically have the same restrictions, as we aren’t producing fish destined for a customers barbecue. We control feed costs as we please, some spare no costs when it comes to feeding pets. A commercial operation doesn’t have that luxury. Hopefully most/many hobbyists view their animals in longevity years, not maximum growth in minimal time, as a farmer would.
Im not trying to make any points about the ol tapioca wafers...
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.
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.
