Even more have shown up, 42 degree water but a lot of bright sunshine in the past several days. Upper teens at night. Counted 32 ribbons in a variety of places.

Have see no ribbons yet in central Indiana, but we are getting the worst snowstorm of the Winter starting now. Spring peeper were singing yesterday. Temperatures predicted in the 50's by Tuesday. Guess that is just March in the Midwest.

RAH, I have been seeing Perch ribbons for better than a week here in east central Indiana.

Gary - Maybe mine are putting the ribbons where I cannot see them, or maybe there are no breeders left (doubtful)? Not sure what effect the GSH are having in my mix of fish either? The SMB should be well fed either way. Enjoy the snow!

We just lost our ice here in Ontario. It was -9 Saturday night here.
Having a warm rain event right now so I should get our branches placed in the pond.
Cheers Don.

First perch ribbon, yee haa! Two days ago, in the exact same corner of the pond as last year and almost the same date (last year it was 2 days later). It was wedged under a pack of oak leaves as if the perch backed in under the pile and then swam out. It was in 6" of water. THe egg ribbon was starting to get leaves on it so I gently fluffed and swished it in the water and laid it in a little deeper water. Will be watching for more soon but we have a nasty cold rainy snowy front coming through today so I doubt we'll see more ribbons this weekend.

Hello.
A little glimpse over the year, I don't find notes for the last years.
Perch spawn, the beginning.
2005= 20 April, water 48F 2006= 10 ... , ... 47F 2007= 20 ... 2008= 20 ... , ... 50F 2009= 14 ... 2010= 2 ... , ... 52F 2011= 16 ..., ... 43F 2012= 1 ... 2013= 6 ..., ... 48F 2014= 12 ..., ... 50F 2015= 5 ... , ... 49F

Good water temperature data for seeing yellow perch egg ribbons in Quebec. Thanks. My first YP egg ribbons are seen at the very same range of water temperatures.

first year for the YP to lay ribbons in my newer pond. Seen 4 ribbons this morning. 3 on the south end on a shallow flat and one towards the NE corner. All were on Christmas trees. My cheap thermometer said 40 degree water temps on top.
.75 acre pond dug in September 2016. YP, HBG, HSB, SMB, and RES.

Back at our pond today. We had a 3.5” rain that must have come down in a very short time. My water level has come up almost 3’. Still 18” to full, but it looks better. Unfortunately the water temp has dropped with the additional water, and lower temps. Now is 42 degrees. No ribbons can be found. Not sure how many ribbons I ended up with, and they are all 3’ deep now. Anyone know if YP will lay any additional ribbons after they’ve started and stopped? I’m guessing they are done. Thx.
9 yr old pond, 1 ac, 15' deep. RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these. I think that's about all I should put in my little pond. Otter attack in 2023

Spawning of YP should continue with an increase of water level. They will seek places to drop the eggs. It is hard to hold back Mother Nature.

Hwllo. Well if winter is prolonged, it means bigger eggs, here they are going to be big, we are 9 April and there is still lots of ice, it is still very cold. http://www.cbc.ca/news/canada/windsor/cl...breed-1.3178898A+

That article also said the YP spawn at the same time of year, without respect to temperatures......seemed to me the thust of that CBC article was pushing climate change more than it was about hard facts and dissertation observations that seem to defy many other(less biased?)scientific observations...

From the original sources
"Although climate warming is expected to benefit temperate ectotherms by lengthening the summer growing season, declines in reproductive success following short, warm winters may counter such positive effects. Here we present long-term (1973–2010) field patterns for Lake Erie yellow perch, Perca flavescens, which show that failed annual recruitment events followed short, warm winters. Subsequent laboratory experimentation and field investigations revealed how reduced reproductive success following short, warm winters underlie these observed field patterns. Following short winters, females spawn at warmer temperatures and produce smaller eggs that both hatch at lower rates and produce smaller larvae than females exposed to long winters. Our research suggests that continued climate warming can lead to unanticipated, negative effects on temperate fish populations."

Well, if short warm winters are a detriment to perch spawning, this year should be spectacularly productive! Snowed three days in a row now, in early April! We had ice on the pond yesterday morning with a low of 18 degrees. Please make it stop.
The ribbons are still there, but I worry that they will fail as they are getting coated with sediment. Too cold to progress.
This weekend it is supposed to warm up a lot, but it is on a razor's edge as the warm front will be draped overhead. The north side gets the 40's, the south the 70's. It wont be the first time our house sits in warmth where only 1/4 mile away is stuck in the cold on the north side. Based on our depressing weather trend, I have little hope we will exceed 50 degrees this weekend. The forecast keeps flip-flopping between pure trash and beautiful.

For me the key is what level of population variation exists to adapt to changing climate. Clearly YP populations exist in very different climates so the species as a whole is adaptable. If winters become routinely warmer, will those individuals that do well under such conditions fuel a population recovery?

Climate change is inevitable and has been doing so since the earth formed. This is a basic fact and is well represented in the fossil record and in the evolution of species. Adapt or go in the waste bin ash heap of history. Change is dynamic with many uncertainties especially as it relates the interaction of species. Change is multifaceted and not linier. The ability to adapt to local circumstances is called phenotypic plasticity and is discussed here http://forums.pondboss.com/ubbthreads.ph...true#Post450474 . Phenotypic plasticity refers to some of the changes in an organism's behavior, morphology and physiology in response to a unique environment.[1] Fundamental to the way in which organisms cope with environmental variation, phenotypic plasticity encompasses all types of environmentally induced changes (e.g. morphological, physiological, behavioral, phonological) that may or may not be permanent throughout an individual's lifespan.

Both heritable adaptation (evolution) and the ability of individuals to physiologically adapt to environmental conditions (phenotypic plasticity) certainly come into play. And then there are heritable temporal changes in gene expression in response to environmental factors (epigenetics). Biology sure is interesting!

The real question is how fast can adaptations be made. Majority of dinosaurs couldn't do it, leaving only birds since they could quickly move to more hospitable climates.
The claim right now is the climate is changing too fast for the ecosystem and adaptations to play catch-up, resulting in some serious problems for wildlife. Yes, the only outcome will be those that can adapt or move to where survival is possible. Personally I don't know what will happen, and I don't want to get into R&P land, I just don't like what I am experiencing. Warm air pumps all the way to the poles, displacing this cold crap, making me miserable.
It snowed again, hard, this afternoon and it wasn't supposed to.

Hello.
I don't know if Yellow perch in florida are spawning at the same temperature as here around 48-50F.

I am not aware of YP in Fla. A recent issue of PB mag has an article on YP spawning and early growth.
We are finding that adaptation in fish can occur very rapidly in some situations. Much faster than I used to believe possible.

I would venture a guess that a body of water containing high genetic diversity would be much better able to adapt than say a pond with a single genetic source for stocking. Chances of having a genetic trait that makes an organism better able to tolerate extreme conditions would seemingly be better.
Intentionally stocking a bow with fish from various regions and sources may give the best results, but also add considerable risk to introducing disease.
