a bit of a tangent, but i've always wondered why "wild-caught" is such a marketing thing. to me, if it's wild-caught, chances are high that it was not done sustainably, which is opposite of how farmed variants are procured.

AFAIK farmed variants aren't exactly sustainable either. They require enormous amount of smaller fish to feed the bigger fish they're farming, and those smaller fish are still wild caught. In addition, fish farms pollute the areas around them, in the form of disease/parasites or waste.
Yes - vitamin B12 isn’t found in plants. Other minerals are also harder to come by, like Zinc and Iron. The bio-available form of Omega-3 Fatty acids, EPA, DHA, and DPA are also only in animal products. Long-term veganism without health consequences isn’t possible without careful supplementation. If you eat fish and eggs, you are mostly covered, although I recall studies showing vegetarians had lower levels of B12 and other vitamins/minerals vs their omnivorous counterparts.
You can get all vitamins/minerals needed by just eating animal products, if you so desire. Plants don’t contain anything essential for human health, so far as we can tell today.
Worth noting that there are a wide variety of B12-fortified plant-based foods available (non-dairy milks, cereals, etc.). One can also find algae-based EPA + DHA supplements.
