That is a GREAT question! It isn't even learning once. If it was you would think something born in captivity and then released into the wild would then have that one time shot. I have no clue. Maybe there is a point of no return with what they learn over time. I'm no behavioral scientist, but I sure know when my darters take food off the surface that isn't normal behavior and something I would want to persist in the wild. Though you could start a dry fly fishing market for logperch.

Fish brought into captivity often show a change in behavior within a short period of time that can make them unacceptable to wild release. Stock raised in a tank is no different, and learned behaviour and traits that could cause problems in the wild stock.

This isn't a rhetorical question. Why is it that fish taken into
captivity learn to act differently quickly, but cannot do the same when
placed back in the wild? Can they only learn once?
