| That really sucks, hopefully the fishery can recover quickly. |
|
| |
|
Location: Grand Rapids, MI | This directly impacts the Great Lakes Muskie restoration in Michigan and Wisconsin. This VHSv outbreak has shut down the egg take here in Michigan for this year which means we will not be sending any fish to Wisconsin. |

| Anymore details, will lakes be stocked this year? |
|
| |
|
Location: Grand Rapids, MI | As noted above, the egg take is off for this year and no GLMUS eggs = no GLMUS stocking. Through our cooperative agreement with Wisconsin there may be some WI strain stocking in the fall.

| So they took roughly a 1/3 of or so of the population out of Thornapple to make room for a strain known to carry VHS. Doesn't make much sense to me. I'm just trying to understand, why the attraction to the Great Lakes strain. |

Location: Grand Rapids, MI | They didn't take 1/3 of the population out of Thornapple, maybe 1/3 of the N. Strain (NMUS) but a good number of those fish were at the very end of their lifespan. The Great Lakes Strain (GLMUS) aren't known to carry VHS specifically, any strain of muskies will carry/contract VHS. An inland event in Budd Lake confirmed that the NMUS are vulnerable, so it's the species not the strain. VHS is simply more widespread in the Great Lakes, fortunately there have only been a few inland events.
The reason the change to the GLMUS was 20 years in the making is because it's the right strain for Michigan, it's the native strain in all but a handful of waters located in the Western UP. The changeover to GLMUS has allowed native species restoration all over Michigan that couldn't be done with NMUS. It's also eliminated some problems with mixing strains in many locations that could cause problems with genetics.
This will be a bump in the road, albeit very frustrating, just as the 2006 event on St Clair was a bump in the road to the GLMUS program. |

| As someone who volunteers for the "clean water/clean boats" program and checks boats at the landing on the chain where I live, I am going to print that news release and have it with me. For the most part boaters are aware of the issue with invasives, but not so much with VHS and that it can hit muskies hard. We give folks literature about keeping the boat and live wells clean and while most understand milfoil and zebra mussels, the VHS issue doesn't have the same level of understanding. |

Location: Apparently where the Muskie aren't | I don't want to high jack the thread but is there any other diseases or viruses that effect fish that look like VHS? I'm asking this because about 2 years ago I caught a northern that looked like it had the same redness that was in the pic of the shad in the link. It looked more like it was bitten or attacked by something but it was a 28" pike and there isn't anything (that I know of) in this body of water that would try to eat a fish that big. And I know it wasn't spawning wounds because it was September when I caught it. Could it be a isolated disease/virus, just to that fish?(I hope so). But I have caught a bunch of other pike after that that looked fine. I have pic somewhere. I'll post it if I can find it. |

Location: Grand Rapids, MI | There are a few pathogens that pike could have that can cause varying stages of skin problems or tumors, Lymphosarcoma is most likely. With VHSv the skin is usually the last sign of the disease, imagine them hemorrhaging from the inside out and generally once the skin shows signs the fish is nearly dead. |

Thanks, it sounds like its probaly not VHS because other than the skin rash it looked very healthy and was very lively. I did find the photo if you have any guesses of what it is. |

| I graduated college in the field of aquaculture, and I can tell you that a lot of fish diseases have very similar outward appearance. Most have to be put under a microscope to be sure. |

| Listening to the am radio right now in the shop. The biologist from the Mich DNR said they've found very few musky with it this spring and it's mostly been Gizzard Shad. Said it will subside by the time the water hits the low 60's. |

I think that means they've found fewer muskies than the 2006 event but all tested have been VHSv positive.

It was great meeting you at the coffee with the DNR event last month. Your informative posts are much appreciated.
Cheers

| Ive heard a few reports from walleye fisherman on the Detroit river reporting several dead muskies. One guy said they encountered about 20 floaters one day. This is complete internet hearsay from another website so take it for what its worth. I fished the D for walleyes 4 times this spring and encountered 2 dead musky, 1 which happened to be a complete BEAST. I did see a few pictures of canals absolutely loaded with dead shad, which might be more concerning. |

| Ive been on the river a few times this spring and have seen a few but not nearly the amount that others have reported. You see a lot of dead muskies all the time on LSC though so its hard to know. Mid/Late summer and early fall is when I think I usually see the most, not usually early in the spring, so it does seem like an increase. |

I see floaters on the river a lot but this year I've seen a whole lot more & many at the ramps, which I usually don't see. Last time I seen 3 to 5 dead muskies at the ramp every trip out was back in 2006, which was the last time VHS hit.

| I've seen maybe 2 dead musky floaters all spring. Lots of reasons fish die... |

Location: Grand Rapids, MI | twelts - 5/28/2017 5:34 PM Any more info on VHS on LSC The disease is only active in cold water, so the event is over. The damage is done and it will be interesting to hear what anglers see the first few weeks of season. If there were hundreds being reported, that would reasonably translate into thousands dead, how many thousands would be a complete guess by anyone. As the season progresses the extent of the damage should be evident, even a loss of .1 fish per acre would be a loss of 20,000 muskellunge.

Location: Grand Rapids, MI | It should go without saying that anyone fishing the St Clair system must clean their boat thoroughly if you're going to be fishing other waters.

| This def not good great point by Will clean everything good guys dont need anything spreading even though water temp should have this about over but dont take any chances we put way to much into trying to create great fisheries |
