The larger fish tended to be stunned for slightly longer because of their larger surface area but I don't imagine this relationship would be maintained for very large animals. Could you electrofish for a blue whale? At what voltage would you have have to set the e-fisher?" Second time with less than two weeks between release in 2017. The answer focuses more on the bad side effects of electrofising, both long term effect on fish and also mentions killing of Dolphins. So it seems more of an protect the animal article than an answer. But the fact is that larger animals (and especially mammals) is likely to die rather than just get stunned. But it is also harder to get any effect in saltwater, which explains why electrofishing is mainly done in rivers and lakes. The higher conductivity of saltwater makes to current prefer to avoid the less salt whale rather than go through it. This is less of an issue in fresh water. So basically it just won't work on blue whales.
