  1. A Lake Ontario specific study on this topic: Bioaccumulation of perfluoroalkyl substances in a Lake Ontario food web https://www.sciencedirect.com/science/article/abs/pii/S0380133021001799
  2. 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.
  3. Interesting, Thanks for sharing !
  4. I think it might not be done for a year or so. They have some really cool Salmon footage from L Michigan. They are amazing videographers, I am hoping to try and film deep April Alewives, out in 400ft, this Spring. Oh that’s 120m for Yankee, ha!
  5. https://mobile.twitter.com/alltooclearfilm Link to the film I was talking about last night at the LOCBA meeting. (Sorry for my audio visual issues) These film makers are great to work with, they get some truly amazing underwater footage!
  6. 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
  7. He was awesome, tons of potential, I let him walk before but once I saw the limp I didn’t want him to go to waste. I need to check but I think he was a 1.5yo, wide but thin, 8pt + a kicker. Only dressed 118#
  8. You all have perfectly described how I think, and what the data suggests, are the factors driving LO alewife year class strength. Warm early springs increase spawn timing and number of spawns which allows the most age-0 alewife to grow as big as possible by winter. Larger size going in to winter increases the probability they make it through to be counted by trawl following spring. Nutrients and larval predation help set a carrying capacity going into winter and then winter duration can have an effect, especially when populations are dense. But we don’t have those densities like we used to (late 70s- early 90s). This is why biologists and managers from that era talked so much about winter severity but you don’t hear that as often now. Now we think spring timing, nutrients, and predation have a stronger influence.
  9. If you post topics you are interested in here related to prey fish, native fish restoration, or other LO fish science I can try to address some of them that night.
  10. Nvm, I’m dumb, they are satellite from 11/20. I still put the most stock in the Monroe Co. #s, thanks BG for posting them. #letsgobuffalo
  11. The bays are waaay colder than that figure suggests. Is that the FVCOM prediction!
  12. I’m a Coastwatch fan and would have said it’s a hot fall but I rely on the #s Gambler and colleagues record and report as being the most accurate on the lake. His graph says we are cold, like 2019. I was thinking it was a ‘warm’ fall air temp wise but the south winds have been crazy strong, tamales sense that those winds ‘should’ blow the warmest water out and let the coldest water in. The south shore embayment temps have been surprisingly cold given the air temps.
