Are these fish that use magnetism to navigate? Like sharks do?
There's a solar storm this week. Seems unlikely. Measuring LF EMF
would be a good start. Maybe a HV cable?
If it's not a neurotoxin it might be a parasite like
Diplostomum pseudospathaceum that is inter-species and
causes the fish to get eaten more easily [0].
