Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Yellow Perch Spawn 2023!!

It is that time of year again! To me YP are the most versatile, reliable, and hardy fish out there. They are also very good tasting, help clean up crayfish, snails, leeches, slugs etc, and very rapidly pellet train. It is also one of the only fish I know of that you can control population fairly easily by removing a portion or all of their eggs. But I digress,

I wanted to start the spawn tracker thread for 2023!

Please note your location, date, water temp or air temp if possible, and details about what side of the pond or how much sun exposure/shade in the area of the first eggs. Some idea on depth and what the momma used to lay the eggs on or around is also helpful. There are web pages that will tell you how many hours of daylight (photoperiod) you have in your area which is also an interesting possible trigger for laying eggs.



In 2020 it was a mild winter with early ice off. Snipe had the first eggs on March 7th quite early! Central Indiana it was March 13th

2020 YP Spawn site

In 2021 it was member bcraley in Ohio and the date was around March 12 or 13, Fayetville, OH had them on the 16th of March. Ohio led the way in 2021. My pond around March 16 or 17. Dr. Luke in Iowa, March 20.

2021 YP Spawn site

In 2022 I had several inches of ice yet on March 22, but Bill Cody had YP ribbons on March 17! JIMS SVT in Southern OH also had ribbons on the 17th. I finally spotted mine on March 24 in cold blustery conditions right after ice out.

Here's hoping many find YP egg strands soon, keep us posted!

Hello.

Every year I take the date the temperature, but this year I will take the % of eggs fertilized in my 2 Yellow-perch pond.
A+

No one has perch eggs yet??? Snipe had them March 7 in the year 2020. In 2021 the southern Ohio ponds all had YP eggs by now and central indiana had them on the 13th (yesterday)

I'm surprised with all the global warming that we haven't seen perch eggs yet this season. We had mostly no ice all year, an early ice out a few weeks ago then are in a cold snap with temps dropping into the teens tonight again so maybe that will slow things down again.

Keep us posted!

"I'm surprised with all the global warming that we haven't seen perch eggs yet this season."


Interesting!!! One could read that to mean it's because there really is no global warming, that's why yellow perch don't spawn earlier, sarcastically anyway!

That wasn't meant to be political, just that we have had very strange winters lately with long stretches of open water, unusual warm and cold cycles, more rain than snow, no ice skating opportunities, greenish grass most of the winter with little dormancy and soil that barely froze in the top inch.

What that lack of typical frost and ice does to insects, or fungus, or crabgrass in my yard, or pests in my garden soil etc remains to be seen.

I read an interesting article that the maple sap run is WAY off this year due to 'global warming' and that soon maple syrup production will all have to shift north. The geographic areas that enjoy maple syrup production even extended down into Virginia traditionally but now the epicenter will probably move up north of the border into northern Canada. Even the epic production centers on the east coast may see their seasons drop off. Producers are having to jump in and tap trees a few weeks early to catch the early run.

We did catch the early run here and had a good run for a few weeks, then had cold, wind, ice storms, rain, then two weeks of bluster and occasional night time snow. We haven't warmed up enough in the day to start collecting again although today the buckets had a little in it. I figure we will probably boil this weekend and wrap it up after a strange year.

How did others do on their maple syrup season?

Climate Changing Maple Syrup Industry

It is odd if the season is warmer and spring comes EARLIER that no one has had eggs yet...

The Amish around here said they have had a great Maple Syrup season.

cc, no worries. I didn't take anything literal from your post. It just struck me as some text with various meanings, to various readers.

Historical Maple Syrup Production in the U.S.

The last 25 years of "global warming" have resulted in a 400% increase in maple syrup production.

It was my father in-laws birthday yesterday. He was telling me that the one birthday that he will always remember in Ontario Canada here was his 14th birthday.
It would have been 1959 March 14th and he said it was 14*C here. Last night it was -7*C

Cheers,

It was 17°F here last night and the local ponds froze back over.

You guys just keep that crap up there where it belongs.

"When the data doesn't match the model - the model is wrong."

Nobel Laureate Richard Feynman remarked something very similar.

When my dad began investing, he assiduously scanned the papers for the experts opinions, and followed their advice. After getting bloodied time & again, he questioned not only them, but all the conventional financial wisdom of the time. Often, diligent research into actual historical observations yielded quite different conclusions.

47.8°F surface temp, 43.4°F at 10' depth.

Won't be long now if they haven't already.

Cecil said he's seen some skeins in his big pond.
Cody Note: I also talked to Cecil today. He had a thin skim of ice on the pond yesterday and saw YP eggs today Mar 16. Being at the same latitude I did not look for any eggs today. I will look Friday at my YP spawning branches.

2 things (that I understand) that must be present. #1-Water temp, #2-length of Day. If time of sun is right but water is too cool, it's delayed. If Temp is right but days are short-neeah--still seems to be a delay.
#3-fish know something we don't and it changes every year-fish behavior seems to change as fish grow and like us, not all think alike.
I know I said 2 things, but there's probably 50 things we may never fully have the answer to..
I think you guys know were I'm at.. haven't had time to go look yet, and 77 degs yesterday went to snow and 25 today. Probably single digits tonight but I will look tomorrow at the tumbleweeds.

Hello.

There is still a lot of ice here, but it is getting warmer.

Since I take the spawning date, since 2005, The fastest spawning was April1-46F-2012.
A+

At least 3 YP ribbons Friday morning Mar 17. Water temp was 45F. Cloudy and windy Friday air temp after dark was 36F. Ribbons could could have been there Thursday to match the spawn at Cecil's.

Cecil was catching gravid females yesterday and today. Males that were caught were spewing milt on the pier when taken out of the water.

Wow, Malinta OH, and wherever Cecil lives gets the price this year! I'm surprised that the south Indiana ponds, and the Kansas ponds aren't having ribbon action yet!
We have blowing snow, wind and cold here. Probably another week yet I'm guessing.

17F right now in west central Indiana.

Cecil is in NE Indiana. 17°F here @ 10:30 am CST, "feels like" 3°F.

"When the data doesn't match the model - the model is wrong."

OR.....the data is incomplete. How many new maple operations have come into existence during the previous 25 years? How about farming innovations that resulting in improvements in efficiency, and yield?? I didn't see that info on the graph? And where was the breakdown that illustrated yield/ per geographic locations within the maple belt??

No?

Well then, since the data posted is incomplete, then any conclusions drawn from it are highly suspect, to say the least. You want to know if the climate is changing? Really want to know? Then stop listening to the politicians who tell you one thing, and avoid the scientists who are claiming the opposite.... run down to the southern reaches of the maple belt, and check in with some farm families who've been sugaring for multiple generations. Ask 'em to show you "the wall"... the spot where their fathers and grandfathers have been writing the dates of "first run" and "all done" for decades. Take some graph paper with you and chart it out. You'll have your answer.

Whether one chooses to bring that graph paper back with them to show others, or quietly wads it up and chucks it into the firebox of the evaporator, will have absolutely no effect on what it plainly illustrates.

When I looked at the wall in the sugar shack of the Amish family that I get my syrup from, it showed the first run/last run dates had no correlation to the "climate change" theorists. And the writing on the wall went on for more than 25 years.

Yep. That's why you need to travel south. My friend, I've been to your home, just like you've been to mine. I saw in an earlier post today where you stated it was 17 degrees. It was 34 degrees down here at the same time. Anyone up there pull some BG through the ice this winter? We maxxed out at 1.5"... never wet a line. Did you know that for purposes of tracking maple syrup production, the IDNR divides the state into North and South at highway 40? The latest data I can access right now comes from 2020, when their production figures show 24,139 gallons made. Of that total, only 1706 gallons came from south of US40.
Southern Indiana is a world apart from Northern Indiana, as I'm sure you recognize. Now, I'm not suggesting that the end of Hoosier maple syrup is imminent. Far from it. There will be warm years, and there will be cold years... that's part of sugarmaking. But the evidence is clear to those of us in the southernmost reaches of the maple belt. Our maple seasons are trending earlier, and shorter. I tend to believe we are the canaries in the maple mines.

By the way, do you know what we southern sugarmakers call your region?........

Michigan! Lol! Hope you are well, Scott!
