No, you'd basically have to eat salmon all day long every day to have any meaningful effect. Eating fish is not a viable or realistic way of maintaining healthy vitamin D levels. You have to either get sunlight or take a supplement. (And I love fish, I eat salmon daily sometimes, but I still supplement with D3.)
I've been taking a daily vitamin D supplement since COVID-19 broke out in the USA. I believe there's a lot of evidence that many people are deficient in vitamin D. I don't know if supplements are the best way to attack that but it's one of the easiest ways. Getting daily sun exposure isn't always convenient and not really possible for a good chunk of the year since we have real winter here.
This brings up something I always wonder when these things come up. I agree with what you said, and there's a lot of evidence that this is bad. But I've seen mixed results over time as to whether or not vitamin d supplementation has a beneficial effect. I assume it's an "it depends on the effect" and sometimes yes and sometimes no

D3 (animal-based) > D2 (plant-based) > D1 (synthetic), at least in humans if you read the literature, that is. The fishy thing is how actual scientists do whole studies using only D1 and then draw conclusions.

Im not sure where this study landed in cancer communities or what subsequent studies concluded. But it's worth noting.
This century it's Vitamin D with the same level of insistence.
Don't hold your breath.

Overfishing is serious enough at this point that I'd rather take a small health risk than contribute to it.

That said, and in light of the comment from https://news.ycombinator.com/user?id=AlecSchueler, in particular - many of the most essential nutrients / 'micronutrients' that are obtained from eating fish are actually not made by fish themselves. Rather, fish 'concentrate' these substances as they go about their own business of survival. For example, vitamin D3, DHA, EPA, etc. Consequently, there are much more readily available 'vegan' sources of these substances, derived directly from the fundamental source(s) - microalgae and the like.
FYI (to all).
Overfishing IS a serious problem. Our activities, in general, are at a scale, and grounded in processes, these days, that produce significant impacts on the environment. Frankly, in the 'great scheme' of things, it doesn't matter a whit. Humans, and even this planet, are not even a droplet in the ocean of the universe, as far as we / I can even get any sort of a solid handle on that concept, now. But, that doesn't absolve us of any responsibility for trying not to absolutely annihilate OUR home.
It's disgusting to be GIVEN so much (none of us had much hand in almost anything that exists now, even what we've 'built' - we can't create atoms, we don't choose when, where, or to whom we are born, many of the opportunities we are afforded in a 'given life', etc.), and treat it as casually as so many do - to be so entitled as many seem to be.
But then, the universe (/ God / gods / whatever concept you prefer) will always have the final say. It'd just be nice to not F things up for everyone else, IMO.
EDIT: I hope the latter bits, above, don't come off as too moralizing - not my intention ... it's difficult to avoid some frustration with some of what the news inundates us with every day, I find.
More importantly - vitamin D3 is also readily produced in our own bodies with enough of the right kind of sunlight (dependent also on skin tone, age, kidney & liver function [etc.], and, ultimately, 'height of the sun in the sky' - i.e., enough ~290-300nm UV rays penetrating the atmosphere at the angle of inclination / solar zenith angle / whichever concept/quantification you prefer). And, this is actually not much at all. While skin cancer is, itself, a risk - this should, of course, be weighed against the importance of vitamin D3 itself. This comment is already REALLY long, but basically, for latitudes close enough to the 'Tropics', typically only 10 - 20 minutes of sun around noon in summer would be necessary. Winter is trickier. Here are a few links that may be useful for more info (in general, Pubmed - searching for review articles, etc. - is usually a good place to start, IMO - depending on how comfortable you are with reading these types of articles, otherwise, backtracing to those that cite them, especially, the efforts at more 'popular press' descriptions of research now produced by journals like Science etc.):

... The 'Linus Pauling Institute' also seems to have, in my past experience, quite good information on 'micronutrients', in particular (with good citations, etc.), for all of Pauling's actual more tenuous beliefs (himself, in later life) about vitamin C:

I have some hard numbers on this in my own health. I'm a pasty north European living in California and I get plenty of sunshine, as I enjoy the outdoors. As I got older, I got increasingly more viral infections and strep throat was a twice a year affair. It didn't occur to me that I could be vitamin-D deficient, but I was, severely. For some reason, 10+ hours of sunshine a week isn't enough for me to make my own. Ove…
OOC what did you use to do this?
