That's not how fishing works. After some threshold growing fish in aquaculture becomes cheaper than fishing, and things get back in balance. Otherwise, salmon would've been extinct by now.
Tuna and herring are not grown en masse in aquaculture... yet. That will change.
- namtab00 3y agoI've always heard predatory species like tuna cannot be farmed, but my knowledge may be outdated
- metal_am 3y agoTuna can’t pump water over their gills. They can never stop swimming
- ravenstine 3y agoSeems like an opportunity for CRISPR to make tunas that are farmable.

- anovikov 3y agoMost prized variety - the bluefin tuna - is now widely farmed already (although farmed one still makes a very small proportion of tuna consumed). But it's possible and is already viable commercially.

- sgift 3y agoI thought the same, but it looks like there was a breakthrough relatively recently making it possible now: https://www.theguardian.com/environment/2023/sep/04/breeding-breakthrough-paves-way-for-intensive-tuna-farming-on-land https://www.theguardian.com/environment/2023/sep/04/breeding...

- alecthomas 3y agoSadly that is how fishing works. Wild Salmon is endangered in many locations including the US [1] and UK [2], for example. It does also occur that popluations become so low that they can't recover. Atlantic Northwest Cod are the most obvious example, still not having recovered from overfishing in the latter half of last century [3].

- Tiktaalik 3y agoSalmon are similarly on the road to extinction due to habitat loss, climate change and over fishing, along with the Resident Orcas that exclusively eat them.
