Hi
I was intrigued recently to read a passing reference to the sale of fish eggs.
I think the contributor was from the USA.. Transportation costs seemed to be a major factor. Logical because I am assuming fertilized eggs are much cheaper to transport than fingerlings.
I think the species mentioned was Trout.
Interesting.
Now obviously temperature control and possibly light are vital.
Species specific conditions would be required.
Niche market for a small agile operator.
I don;t see a large market in the UK for trout ( already saturated) but other species could prove interesting.
I am thinking European Perch and Arctic Char.
Obviously lots more reading and research but is any body on the same road?
Sign posts?
Highway to hell?

It's an interesting concept..
I would be happy buying them and porting them, because I believe I know how to do it, but I would wonder how you could reliably send then by post or carrier, given the general need for air etc. and separation..

The only consideration is that if the fingerling suppliers can port fish in small plastic bags with oxygen, then perhaps eggs will need LESS O2 and the general movement will assist in maintaining viability..

It'd need to go to the right people, and the skill set to raise fry.

Something like goldfish would be easy (but they don't stay in eggs for that long). But many other fish are far pickier, and people will have a high kill rate of fry if they don't know what they are doing (I'd probably be one of them).

On the other hand i know I've seen feed marketed for tilapia fry on a bunch of different sites, and most things say that live bloodworms, and Seamonkeys/brine shrimp are good feed for most aquarium fry. Problem is finding cultures for those. Food for thought anyways.

Daphnia make good feed for small fish depending on how large the fry are. Guppy babies (fry?) are so small they can't eat the daphnia but when they get just a little bigger, they can chow on them. I would imagine tilapia fry might be larger?

Plus aren't tilapia live bearers? I feel like that means bigger fry.

As far as I know, tilapia lay eggs but are "mouth brooders", the female keeps the eggs in her mouth for protection.

Right! I've read about that, I just don't have personal experience with em. For some reason I thought all cichlids were live breeders, which makes zero sense, I can't think of a single one that is, script except maybe escaped convict cichlids.
