In fact, thinking more about their presence here...

Isn't a net expansion of weed growth one of the main factors that's preventing successful spawning of lake trout on many bodies of water? The weeds are growing progressively thicker and progressively deeper, chocking out the areas required by the trout to spawn. Maybe a few grassers swimming around (and not being able to reproduce) in some of the 'trout' lakes wouldn't be such a bad thing, as they'd eat the weeds thereby opening up spawning beds.
