  1. Apparition, I think the differences in the maps may be because GillTs map is based on satellite observations and the map you were showing is the results of the FVCOM model, for surface temperature. The Finite Volume Coastal Ocean Model uses bathymetry, wind, and air temperature observations data and a bunch of

    equations to make predictions, whereas I think satellites are using direct infrared observations, which have trouble with clouds and are only surface temps. I’m out. Of my depths on this stuff but the NOAA sites and google have much better explanations. The FVCOM approach is  state of the art and it’s super cool that GLERL has it up and running. For my research we use it a lot in the spring to figure out when and where we might dodge the ice to start sampling as early as possible in Chaumont Bay.

  2. Dances, yes.
     

    Like the pen stocked trout and salmon we are testing if we can improve survival when they have a few days to become ‘conditioned’ to the water where they are stocked. This is our first time trying anything like this so quite a few obstacles to overcome.
     

    I’m aware of Cisco eating alewife in Lk Michigan and probably annywhere there are big Cisco and small alewife , but I haven’t heard or seen evidence of Bloater eating Alewife. Cisco tend to live shallower and closer to shore, whereas Bloater are smaller, live deeper, and focus on eating Mysis shrimp.

  3. The pen is north west of the lighthouse, is marked with 4 high flying float flags surrounding it, and 2 yellow surface floats.

     

    The net will be in that location till Monday and then there may be another one set for a few days deeper. These are experiments testing ways to increase survival of stocked Bloater.

     

    Best to give the marker buoys a wide berth to avoid snagging and losing gear. Happy to address questions or concerns. Thank you!

  4. Oldest I see in our records is Age-7.  Not many in that age (0.06%) and length on the age-7 ranged from 6 to 8 inches. Largest I see that we interpreted an age is almost 9 inches and that one was interpreted as age-4.  You might have seen in my talks how Alewife growth (size at age) changes when fish hook and spiny water flea populations are really abundant.  Interestingly those changes didn't seem to change RS growth.

     

  5. IMO From a fish habitat perspective those 6 dams on the Oswego  River have some of the , if not the largest negative impact on LO fish populations AND local resource based economies. The canal creates completely nonnative impounded aquatic habitat in place of what would be 25+ miles of high gradient warm-cool water river habitat that would produce or support walleye, SMBs, sturgeon, American Eel, and likely many of other native fishes, in addition to the lake-run fisheries for salmonids. The Dams Also limit what I surmise would be impressive  rafting - kayaking opportunities. The Dams limit the natural recruitment and pulse of wood into the lake which I suspect doesn’t help the ever dwindling native lake population of Slimy Sculpin which use wood to spawn (adhesive eggs).

     

    In the place of these resources there is some modest electricity produced , that from my understanding does not lower local energy costs , And of course the ever important a handful of boats get to traverse to Lake Ontario from the canal. Would live to see the math on what that contributes locally.
     

    From a decision making standpoint it seems very odd to me why those dams are still in operation. If I owned land in that area I’d be asking my representatives daily why support habitat destruction and impede resource based economies. Maybe this will be windmill I tilt at in my retirement. 
     

    soap box over, happy to hear and consider alternative viewpoints
