That could be true, but the reality is that historically, fisherman have aided in the introduction of numerous species, where prior to that were never seen.
Invasive specie a threat to salmon.

Highly agree with that… states natural resource departments are often the worst for spreading non natives… this case seems cut and dry tho. Pike leaves a river, enters the ocean and moves to the next. Alaska looks pretty close to sweden specifically where the same type of thing happens. Oceans/estuary/rivers/swamps/ where fresh meets salt that all flood. Endless opportunity for a fish that enjoys salt content. Anything is fair game.
For sure… def. not trying to discredit a local with 40yrs life experience there. Im just surprised i guess there was any strong hold of pike free waters being surrounded by them. This map looks like a straight invasion with many routes in from all directions.
No we won't!
Okay...in the article that @RD. linked, they state:
"Invasive species are plants or animals that do not naturally occur in an area and can negatively affect the environment, the economy, and/or recreational activities."
The article in the original post of this thread talks about an illegal introduction of pike into a lake, from which they spread through flooding into nearby fresh waters. That would appear to align with the above definition of "invasive".
But the same article mentions testing that proves that one of the matriarchs of that "invasive" population had indeed spent time in salt water before re-entering and subsequently contaminating another freshwater system. If that fish moved on its own, and was not towed there behind a fishing boat or in the mouth of an Orca...then by definition that means that it got there naturally...so can it be invasive?
Or...did that fish and its buddies enter the ocean from a system that they were introduced into illegally? That would seem to qualify their presence as unnatural an invasive, but...it doesn't actually state that....so...?
Beats me; perhaps I am too skeptical of anything the gummint tells me...

The kenai peninsula is for sure a special little slice of heaven that city folk and lower 48 yahoos have done their best to muck up
not suprising, i lived by tahoe for a bit and found out people would bring live muskies and other pikes to release into the lakes around here so they didnt have to travel to fish for them, wouldnt be suprised if that was the case in alaska
The original pioneer invaders were put in lake bulchitna by a douche bag in the 50s and steadily spread out from there
This is a pretty good article about it
