    Direct from our “inside” connection at the DNR, Mr Rod Rasell!

    Thanks Rod!

    I”m not going to place Rod’s email in quotes so it doesn’t lose it’s formatting.

    To date we have tagged 395 LKS in the Lower St. Croix River since May of 2003. We have had a total of 73 recaptures of 61 different tagged fish. Nine fish have been recaptured at least twice, with 3 of those individuals being recaptured 3 times. In the first two years of our mark/recapture project we had no recaptures. During the next two years we had a total of 22 recaptures reported (10 by us and 12 by the public). In 2007 we had another 51 recaptures reported (9 by us and 42 by the public). Two things likely account for most of the significant increase in recaptures: (1) we now have more fish tagged out there and the chances of catching a tagged fish are much higher, and (2) more awareness of the fact that some of the sturgeon are tagged and how to report them, so anglers are now watching for tags and contacting us (many thanks to the message boards, especially IDA, for talking about catching tagged sturgeon and getting the word out to watch for tags and how to contact me for reporting and getting feedback about the tagged fish!). The fastest reported recapture was 4 days after initial tagging, and the longest interval between tagging and recapture to date has been 1,469 days. Five of the reported recaptures are of fish that have emigrated from the Lower St. Croix and have been recaptured down stream from Lock & Dam #3 as far south as Lake Pepin. The location of recaptures of tagged LKS have ranged from 14.7 miles upstream to 51.8 miles down stream from the site of initial capture and tagging. None of our tagged fish have been reported harvested through the new harvest tag program.

    Following are the totals reported through the harvest tag program for the last 2 years. In 2006, 5 LKS were harvested measuring between 51 and 60 inches in length. In 2007, another 7 LKS were harvested measuring between 51 and 60 inches in length.

    Many Thanks Rod…it’s alway interesting to hear the data collected.

    Wonder if I could get St Croixer down to the St Croix with his camera??
