In Michigan, the Lowramouth bass virus is confirmed in additional ponds

Lensing, Mitch. – The Montemouth bass virus has been found in two additional lagoons in Michigan's Northern Lower Peninsula, after the initial discovery in Cedar Lake (ISOCO County) in late October.

This time the LMBV fish was found in a small nest in Beaver Lake (Alpena County) during the assassination and the investigation of Avalon Lake (Montmorin County). These latest discoveries indicate that the virus is spread northward in Michigan.

Prior to this fall, the virus first affects the adult motomouth bass in the early 2000s of the South Michigan lakes. In those ponds, immune system was destroyed in the first population by 10 to 20 percent of the older adult mozemouth bass, in which the population had been recovered for a few years. The virus has been found in other species, in which part of the state includes small mountain basses, bluegraphs and black capsules. Bluegill and Black Crappie are known to be carriers but they do not die from the virus.

Gary Whale, research manager at the BNR Fisheries Division said that the Mosheimout bass virus can tame the small head bass immune system in Beaver Lake, causing secondary bacterial infections to become more deadly and a direct factor in killing fish. . "Because this latest speculation is on the northern shores of LMV, so we can see different responses than documented documents in South Michigan."

LMVV is one of the more than 100 naturally occurring viruses that affect the fish and is closely related to the virus found in frogs and other amphibians. Its roots and diffusion methods are unknown, but the Anglers are considered a possible transmission path. Moving any living, infected fish from one part of the water to another, or using viruses in contaminated or impure gear or waste water can easily spread the virus. LMV is not known to infect humans, and infected fish – if fully cooked – it is safe to eat.

LMV is usually killed in large-scale strains of fishes. Potential strains include hot weather, increasing recreational fishing, and possibly other anterior grass or other treatment done during hot weather. Anything that can be done to reduce stress on fish reduces the effects of this virus and subsequent fish death.

There are little external signs that fish have LMV. This virus has been found in the lakes where no disease or fish has been killed. Affected fish usually appears normal, although they may be sluggish, swell slowly and can respond less to their surroundings. The fish of death is often found near the surface and it is difficult to stay up. After internal inspection, infected fish are usually bloated and yellow drilling blades.

The Lauremouth bass virus can not be eradicated from the lakes and transmitted fish can not be cured. The best way to stop the virus is by using anglers and boaters to properly clean their equipment and prevent their spread. Simple steps include:

  • Clear all fishing equipment between the trip
  • Do not move fish or fish parts from one part of the fish to another.
  • If you intend to rescue them, then handle bass slowly.
  • If you plan to leave them, avoid having a bass in live longer living.
  • Reduce the target of Mozmouth Bash during the very hot weather.
  • Reporting of dead or dead adult Motmouth Bash, especially when they are 25 or older – reports can be done online in Michigan on gov / EyesInTheield.
