99 days and counting for 18!

18 has now been in Shu Swamp for an astounding 99 days without losing battery power. This is a 18 locationsmap showing the locations of 18 following release. You can see there are three clusters of locations. After release on 10/23/13, 18 moved about 470 meters downstream to a location in the middle cluster on 10/25. It then moved another 50 meters downstream to the top cluster by 10/28 where it remained until sometime between 12/22 and 12/26. On 12/26 it was located at the middle cluster again. It remained there until mid January and now seems to have shifted another 30 meters upstream (bottom cluster).

The first photo below shows the  area where the second (middle) cluster of locations were. Again lots of overhanging vegetation.

12-23to1-20And this is the current area (bottom) we are locating 18. On Sunday, 18 was right under the center of the small log going over the stream (the y-in the red branch is aligned with it). Today it was close to the nearer bank and under the overhanging vegetation at the bottom right hand corner of the photo.IMG_20130130_113902_335 copy

96 days for 18!

Beaver Lake January 27, 2013Beaver Brook Lake is completely frozen over. There were ice hockey games on the lake today. #18 had moved upstream about 10 meters to a bend in the brook. We actually saw it in midstream under a small fallen tree. 18 has really grown and looks about 8″ in length. S/he was only 6″ 3 months ago when released. But s/he wasn’t alone. There was a smaller trout AND a turtle a few feet upstream resting on the bottom. Just sitting there soaking up the rays. Water temperature was 7 C. I’ll try to add pictures later if I can get the files off my stupid camera phone.

Alewives and Beaver Brook

Some members of the Diadromous Fish Working Group visited Shu Swamp to check out the area. Here we are shivering at the Cleft Road Bridge:

And here’s the spillway with antenna on this icy day:

Beaver Lake Dam Antenna with Ice

This spring mature alewives were observed trying to make it over the dam. This fall we observed young-of-year alewives shoaling in the pond just south of LIRR. There is a lot of interest in opening up more spawning areas to alewives so this looks promising. Of course the dam may be acting as a significant barrier (although apparently some are getting through). We want to see just how many are so we are going to PIT-tag arriving alewives this spring and see whether they make it into the lake.

North of Mill Creek you can see a bunch of Canada Geese resting on the ice. Four of these geese have orange collar tags around their necks. They are from Canada! Imagine that, real Canadian Canada Geese!

Trout 18 over 90 days activity!

We released #18 on October 23. We now have three months of activity. It hasn’t moved much the past week. He was underneath this overhanging vegetation this past Sunday:Trout 18 1_20_2013

Today it moved about 2 meters back under a larger bunch of overhanging vegetation where it has been located for several previous weeks. Water temperature was 4 C. Given how cold it is today I don’t think it gets any lower than this.

86 days for #18

Tag #18 continues to set records, now 85 days of activity and counting. Yesterday I tracked it to an spot of a dense overhanging vegetation about 20 meters downstream from its location last Sunday. This is an area it has been hanging out in for the past few weeks.

I also changed the batteries on the antenna at Beaver Lake Dam. No hits since September 29, 3 days after the last release. I also uploaded data from the temperature data logger. This image shows dramatically how saltwater from the creek is a regular visitor to the lake (HINT: it’s right above the “CE”).

Temperatures at the dam have been pretty cold for the last month hovering between 0° and 5° C  except for a brief 4 day spell in the second week of January when temperature surged to 7° C.

Adopt-A-Trout Goes Live!

The Adopt-A-Trout web page is not quite done but it’s close enough to publish. I will post on the blog with upcoming research and education activities. You will get blow-by-blow accounts of field activities by the day.

To orient yourself start with the welcome page. The FAQ page and the radio-tracking data page are still under development but should be ready to go soon.

Right now the Beaver Lake Dam antenna is still active and should remain so through the winter. I shut down LIRR antenna for the winter because I didn’t want to lug the batteries back and forth. We released our last group of radio-tagged fish October 28. All but one, #18, has gone silent. #18 has been going strong for 83 days now, which is quite amazing since the tag life is supposed to be 40 days! You can see animations of the more interesting tags one the site. We should have an interactive map of the radio-tagged data shortly.

Let me know what you think!
