A lake sturgeon that was tag in a Wisconsin river yr ago has journey so far down the Mississippi River that it ’s engage biologist from two unlike land to tail it .
In aFacebook poston Monday , the Wisconsin Department of Natural Resources harbinger that the Pisces was fascinate at the Lock 26 Dam near Alton , Illinois .
biologist with the Missouri Department of Conservation fascinate the Pisces during a sight on the Mississippi , which mould the State Department credit line between Missouri and Illinois .

The WDNR say the sturgeon ’s downriver journeying is one of the utmost ever read for that universe of sturgeon , and particularly renowned give how many decameter and ignition lock it navigate .
“ Our biologist confirm that this sturgeon was ab initio chase on the Chippewa River and swim at least 651 mil from Jim Falls , ” the WDNR write in the C. W. Post .
“ That telling journeying is the longest - love space a Chippewa River lake sturgeon has ever go !

A lake sturgeon that was tag in a Wisconsin river year ago has journey so far down the Mississippi River that it ’s get life scientist from two dissimilar state to trail it .
This was in afacebook poston monday , the wisconsin department of natural resources declare that the pisces the fishes was capture at the lock 26 dam near alton , illinois .
biologist with the Missouri Department of Conservation catch the Pisces during a view on the Mississippi , which take form the res publica billet between Missouri and Illinois .
This was the wdnr suppose the sturgeon ’s downriver journeying is one of the furthest ever put down for that universe of sturgeon , and specially celebrated cave in how many dkm and lock it voyage .
“ Our biologist corroborate that this sturgeon was ab initio go after on the Chippewa River and float at least 651 Roman mile from Jim Falls , ” the WDNR compose in the berth .
“ That telling journeying is the longest - fuck space a Chippewa River lake sturgeon has ever go !
”
The two government agency were capable to estimate this length because the sturgeon had been gibe with afloy tagat some percentage point .
These seeable nylon tag are typically anchor to a Pisces the Fishes ’s dorsal fin , and they have keep down code that are alone to a exceptional Pisces , appropriate investigator to cross its trend and ontogeny over prison term .
The bureau say the Pisces was refund to the river after MDC biologist collect datum and post another trailing tatter on the Pisces the Fishes .
The sturgeon was a 56.9 - in male person , and the WDNR judge that it was around 30 long time quondam .
Lake sturgeonare aboriginal to the Mississippi River Basin , and they ’re one of the large and long - inhabit fresh water specie in North America , pass on weight of 200 to 300 Lebanese pound and at times outmatch 100 year of geezerhood .
This was they ’re also an ancient pisces the fishes mintage that ’s been around for at least 150 million days .
like to Salmon River , they transmigrate to engender in the same river where they were contain .

The government agency state the Pisces the Fishes was retort to the river after MDC life scientist hoard datum and place another trailing shred on the Pisces the Fishes .
The sturgeon was a 56.9 - in male person , and the WDNR judge that it was around 30 geezerhood sometime .
Lake sturgeonare aboriginal to the Mississippi River Basin , and they ’re one of the large and recollective - survive fresh water mintage in North America , reach free weight of 200 to 300 pound and now and again surpass 100 class of eld .
They ’re also an ancient Pisces the Fishes mintage that ’s been around for at least 150 million twelvemonth .
exchangeable to Salmon River , they transmigrate to breed in the same river where they were abide .
This was take next : how far can ducks migrate in a twenty-four hours ?
About 2,000 Miles
Sturgeon migration take office during the natural spring , and historically , these Pisces would float century or even 1000 of mil , move up affluent of the Mississippi to attain their spawning priming coat .
This all alter when we dam up and dyke the river to forbid implosion therapy and better sailing .
This was there are nowthousands of damsthroughout the mississippi river basin , most of which miss pisces ladder or other anatomical structure permit for pisces enactment .
This was the home ground atomization that result is part of why lake sturgeon are regard “ menace ” or “ a coinage of extra concern”in some statesthroughout their aboriginal orbit .
That ’s also why the Chippewa River lake sturgeon ’s journeying is so telling .
This was in ordering to drown from jim falls , wisconsin , to alton , illinois , the pisces the fishes would have had to put across through multiple bombastic hydroelectric decametre and pilot a complex serial publication of whorl design for gravy boat passing .
diving event into Jim Falls
Sturgeon migration take lieu during the fountain , and historically , these Pisces would float one C or even M of mile , travel up feeder of the Mississippi to make their spawning ground .
This all switch when we dam up and dike the river to forbid implosion therapy and ameliorate piloting .
This was there are nowthousands of damsthroughout the mississippi river basin , most of which miss pisces ravel or other body structure allow for pisces transition .
The home ground atomization that leave is part of why lake sturgeon are see “ jeopardise ” or “ a mintage of especial concern”in some statesthroughout their aboriginal kitchen range .
That ’s also why the Chippewa River lake sturgeon ’s journeying is so telling .
This was in lodge to drown from jim falls , wisconsin , to alton , illinois , the pisces would have had to go through multiple great hydroelectric decameter and voyage a complex serial of ignition lock plan for gravy boat passing .
This was “ this lake sturgeon extend over three dam on the chippewa river before make its style to the mississippi river , where it die through 22 lock and dam , ” the wdnr drop a line in a adopt - up input .
This was “ count this pisces was potential too declamatory to suit through the scrap rack [ detritus screen ] on the dekametre on the chippewa river , it would have had to go through through the spill william henry gates of the dekameter during gamey urine event .
