There is a lot of potential in fish welfare/stunning. In addition to what others have mentioned, IIRC from some reading a few years ago:
The greatest bottleneck in humane slaughter is research, e.g. determining parameters/designing machines for stunning each major species, as they differ so much. There just aren’t many experts in this field, and the leading researchers are mostly very busy (and pretty old), but perhaps financial incentives would persuade some people with the right sort of background to go into this area.
As well as electrical and percussive stunning, anaesthetising with clove oil/eugenol seems a promising and under-researched method of reducing the pain of slaughter. Because it may just involve adding a liquid/powder to a tank containing the fish, it may also require less tailoring to each species than than other methods (though it can affect the flavour if “too much” is used). I have some notes on this if anyone is interested.
Crustastun could be mass-produced and supplied cheaply/freely to places that would otherwise boil crustaceans alive. I seem to recall a French lawyer had invented another machine that was even better (or cheaper) but was too busy to promote it; maybe EAs could buy the patent or something?
