In case anyone is curious about cell cultured seafood as well, here's a paste from a reply I made elsewhere:
I like to look at GFI's yearly state of alternative seafood reports [1] to get a sense of the landscape. New harvest has a good list of research they have funded which gets into the weeds a bit [2], check this one for example [3]. We wrote some pros and cons in my recent article that may be interesting [4].
This is a list of some players: Finless Foods, BlueNalu, Wildtype, Shiok Meats, Bluu Seafood. Most are at the pilot plant stage and have announced reaching market this or next year. Note that the investment landscape have changed dramatically last year, so timelines will likely change.
Finally: I think its going to be exciting to see alternatives coming out soon. For me the pros are definitely welfare and biodiversity related, while the cons are feed and co2 related.
Only high value species are interesting for the cultivated meat indsutry. The overwhelming majority of salmon is farmed, especially atlantic salmon [1, page 17]. Yellowtail tuna is increasinly farmed as well, but sure wild stocks of tuna are still getting depleted.
Eating chicken or some other meat is not better than eating fish.
Farmers ensure they have cattle for next year. The fishing industry doesn't take that care over next years stock.
Stop eating fish. Please. Just move to chicken or some other meat.
