"Roughfish" species making the news in a very sad way...
<p>After reading the article below, it seems quite logical to deduce that more northern and upstream populations of &quot;roughfish&quot; are very important to support and replenish populations of these fish lost this summer in the heavily drought-affected areas of the Midwest.&nbsp;</p> <p>&nbsp;</p> <p><a href="http://news.yahoo.com/thousands-fish-die-midwest-streams-heat-183228110.html">http://news.yahoo.com/thousands-fish-die-midwest-streams-heat-183228110.html</a></p> <p>&nbsp;</p> <p>However, would it be too extreme to also deduce that practicing catch-and-release of these fish in heavily drought-affected areas should be temporarily banned to protect these drought-threatened populations? The article doesn&#39;t address any specific long-tern effects: how will the sudden loss of apparently large numbers of native species affect the aquatic ecosystem as a whole? Will these native populations bounce back on their own, or will they need human intervention? Will the empty niche be taken advantage of by invasives, bighead carp in particular, and make that situation even worse?&nbsp;</p> <p>&nbsp;</p> <p>Any thoughts?</p>

That's a pretty severe

That's a pretty severe situation.  It seems they at least wrote about the roughies in a positive (or at least not negative?) light.

As to how to fix it?  Well, can be fairly certain that it is not the first time in history that a massive die off has happened (whether or not due to heat) and likely won't be the last.  Perhaps they do nothing (other than cleanup the kill) and let nature take its course.  Restocking might be plausible for some species, but unlikely in the redhorse scenario.

 

 


It doesn't matter what you're fishing for, just as long as you're out there doing it.

Fish never needed human

Fish never needed human intervention millions of years before us. it may take a decade but they'll be back.

I'm sure the bass, walleye,
I'm sure the bass, walleye, trout, pike, muskies, catfish, stripers, and maybe even sturgeon will be re-stocked. That's better than nothing but like Russo said, even if it takes a decade the fish populations will eventually rebound. Down here, we had a massive fish kill in the Powell River in 1994 from runoff from about half a dozen coal mines. The river wasn't worth fishing for about 15 years, but now the gamefish, catfish, & sucker populations are strong, and the gar & drum populations are improving dramatically.
