If there is any confusion, promote native fish species and get rid of the others to the extent possible.
I believe in Mid-Atlantic states the muskie that are stocked are what they call tiger muskie, a hybrid between northern pike and muskellunge. Because they are a hybrid, they are unable to reproduce, and thus they do not establish themselves in the same way the northern pike are doing in Maine...For some unknown reason, the PA Fish Commission seems to love stocking toothy species in the lakes here. As far as I'm concerned Muskie, Northern Pike & Chain Pickerel should all be thrown into the weeds to feed coons & bears. (Carp too while we're at it although they are fun to shoot with a bow)
Agreed. Hate the universal DH.It's really not hard to catch pike as they are voracious eaters and, yes, they can do a lot of damage to trout, bass and other game fish populations. They're basically just slimy eating machines that will strike hard at any flashy (especially white) object that one drags through the water. Yes, like Muskie, they get quite large but I know very few people who care to eat them so they almost all get released so they can eat more, get even larger and, someday, make some dolt feel he did something special by catching a swimming trash can.
IMO these are probably the same people who, with their 10 second attention spans & need for constant action would rather watch some washed-up corner outfielder who can no longer field his position bat for the pitcher and have now made MLB a little less worth watching.

Glenn, you're presenting a very anthropocentric position.

And therein lies the catch. If you believe that the world is here to solely benefit man, then I guess you feel we can do what we want as long as mankind benefits. If you believe that the non-human world has intrinsic value independent of their direct value to man, then there is a lot we can do to support this intrinsic value, sometimes conceding that there may be a human cost. I, and probably most scientists, fall in that category. These are contrasting ontological positions based on culture, religion, etc.Yes, because I think most natural systems should be attuned to the betterment of the species homo sapiens rather than some other species. Should homo sapiens take a salmoncentric or pikecentric or wolfcentric position instead?
So are you speaking for all of us? That we all want introduced game fish in our streams and lakes?Yes, because I think most natural systems should be attuned to the betterment of the species homo sapiens...
And back in New England western rainbow trout (along with Eurasian brown trout) are stocked in native brook trout streams. We just can't leave well enough alone. ;-)We have plenty of Brook trout, Kokanee salmon, Brown trout, Lake trout and other species in the West in places where they were never native.
So are you speaking for all of us?
That's the problem, Glenn. Not everyone wants walleye and northern pike introduced for sport fishing; so are we supposed to just go along with it because other people do? There's probably a compromise that could work for both opinions but if the pro-game fish crowd takes things into their own hands the results are most often irreversible.I only ever speak for myself...
...to maximize any necessary tinkering for human welfare.
Does not take a genius to look up all the bad things that have happened when mankind introduced invasive species to the natural environment.
soo, you've never heard of the feral hogs that are decimating half of the continent, tearing up plants, watersheds, and forests, and killing small birds, animals, and insects???Many introduced species are very beneficial or neutral. Just focusing on North America, chickens, goats, cattle, horses, pigs, honey bees and thousands of other animal and plant species have been beneficial or neutral though non-native and introduced by colonists.
"Invasive" is a loaded term that cannot necessarily be determined a priori. A non-native species, sometimes introduced because it was thought to be beneficial by naturalists or scientists du jour, often turn out to be deleteriously "invasive" only (long) after the fact.
As to game fish, which this thread was started about, the concept of "invasiveness" seems to be mostly a function of their desirability as sport fish or eating fish in different areas of the continent. Manipulative stocking of native and/or non-native species for these purely anthropocentric reasons seems to be ubiquitous.
It is. The questions are: (1) should we continue to do it in the areas where non-native fish have not yet been introduced and (2) can it be reversed where it has already happened? Here in the DC/MD/VA area someone released snakeheads into some ponds in the early 2000s. Snakeheads are considered a delicacy in certain Asian cuisines but are also a voracious predator. It can also "walk" considerable distances on land to get from waterbody to waterbody. They made efforts to eradicate it with poisons and electricity and instituted "catch and kill" fishing regs, but to no avail. Now this fish is well established in the Potomac and threatens the native sport fishery. But fisherman also think they are good sport fish.Manipulative stocking of native and/or non-native species for these purely anthropocentric reasons seems to be ubiquitous.
Many introduced species are very beneficial or neutral.
It's human nature to want to "improve" things for ourselves and for future generations and the degree to which our actions improve anything is usually very subjective. In their haste to implement improvements, people who are confident in their own superior cognitive abilities often overlook (or simply ignore) the deleterious effects of their actions and those unintended consequences become their legacy.soo, you've never heard of the feral hogs...
