00:00.000 --> 00:06.380
Joe, you like, I guess I don't know if you want me to like tell you in advance what I'm going to do or

00:06.380 --> 00:08.060
and then take a picture.

00:08.060 --> 00:13.640
So I'll just kind of follow me back on that and then I might just have you, when we get the phone up to the

00:13.640 --> 00:17.240
lines, I might just try and then frame the get a shot up through that your phone.

00:17.240 --> 00:23.000
Okay, thank you, thank you so much for being here in this building, I'm so glad to see you.

00:23.000 --> 00:26.520
Um, cool, so like, well, do you want me to like talk while I'm doing it?

00:26.520 --> 00:29.720
You know, narrate what you're doing as you're doing it and what you're looking for if you can.

00:29.720 --> 00:36.280
Okay, um, yeah, so these are walleye eggs we collected this morning when we were fight netting.

00:36.280 --> 00:43.920
Um, and I'm just taking them out of the vial and putting them on the scope so that I can photograph them.

00:43.920 --> 00:50.520
And you're too small, so like, I'm just throwing them out a little bit.

00:50.520 --> 00:57.240
And I, I can like make this process shorter.

00:57.240 --> 01:00.920
Normally it takes like each sample takes a little bit to like sprout them out good.

01:00.920 --> 01:03.120
So I can just take a picture if that's easier.

01:03.120 --> 01:06.520
No, whatever you, whatever you usually do, that's, that's fine with me.

01:06.520 --> 01:07.520
I got nothing but time.

01:07.520 --> 01:08.520
Okay.

01:08.520 --> 01:09.520
Um.

01:09.520 --> 01:15.520
So what's the process for someone to go for it?

01:15.520 --> 01:16.520
Super simple.

01:17.520 --> 01:23.520
So basically like anybody that would like to fish here, you know, they have to pop into the station here.

01:23.520 --> 01:26.520
I think it's literally just this right here.

01:26.520 --> 01:29.520
And so we just do them a little pencil.

01:29.520 --> 01:32.520
Uh, we did, you know, their address and a couple of things.

01:32.520 --> 01:35.520
A little bit of demographic data.

01:35.520 --> 01:38.520
And then that's really it.

01:38.520 --> 01:40.520
At that point.

01:41.520 --> 01:50.520
And then you can just line it up through the scope.

01:50.520 --> 01:52.520
I'm actually going to get found on a fine plate.

01:52.520 --> 01:54.520
Like, don't report out when they get done.

01:54.520 --> 01:55.520
You know, we've got a letter.

01:55.520 --> 01:58.520
We try to call them, send them that stuff.

01:58.520 --> 02:03.520
Um, so then after they go out fishing, um, we would mark down, you know, the date and stuff like that.

02:03.520 --> 02:05.520
What time they started fishing.

02:05.520 --> 02:07.520
Um, they didn't have the analogy here.

02:08.520 --> 02:14.520
And then later I just put these photos into image processing software.

02:14.520 --> 02:25.520
And what we're doing is looking at the diameter of the eggs and the yolk basically to look at how walleye eggs.

02:25.520 --> 02:31.520
You know, how like different, let me think of the right thing to say.

02:31.520 --> 02:35.520
Basically like, how do walleye eggs influence recruitment?

02:35.520 --> 02:41.520
How are walleye eggs part of the, how does that like set up?

02:41.520 --> 02:45.520
I mean, I'm sorry.

02:45.520 --> 02:49.520
I'm thinking basically like while I recruitment is declining.

02:49.520 --> 02:54.520
And one of the things that kind of came out was maybe that that maternal effects could be important.

02:54.520 --> 03:00.520
So well, how, how might the female walleye influence recruitment?

03:00.520 --> 03:03.520
Well, maybe it's something to do with the eggs.

03:03.520 --> 03:09.520
So, and there's studies that have shown that if eggs are bigger, that the larvae will be bigger.

03:09.520 --> 03:11.520
So maybe they'll have some sort of advantage.

03:11.520 --> 03:17.520
And then how, you know, that yolk and that nutritional investment in the egg could influence that as well.

03:18.520 --> 03:21.520
So like, and we looked at all these different.

03:21.520 --> 03:28.520
So we did a study recently that was published and we looked at female size, female age.

03:28.520 --> 03:37.520
We looked at environmental factors, like variability, looked at like different kind of population level factors,

03:37.520 --> 03:43.520
like yellow perch and just looked at, you know, how was egg size being influenced by all these things.

03:43.520 --> 03:56.520
And it did seem like the main focus seemed to be that environmental variability can influence eggs.

03:56.520 --> 04:02.520
So if in years where forage isn't as abundant, it seems like maybe the eggs are less provisioned.

04:02.520 --> 04:04.520
They're not as nutritionally dense.

04:04.520 --> 04:12.520
And it seemed like some of these factors, the most important factor ultimately seemed to be like maybe a genetic factor.

04:12.520 --> 04:18.520
So maybe some walleye are just generally better at producing eggs and have generally better,

04:18.520 --> 04:20.520
and which might influence their recruitment.

04:20.520 --> 04:24.520
Yeah, so that's why we're keeping the study going, even though we already published on it,

04:24.520 --> 04:26.520
because we're trying to build up that long-term data set.

04:26.520 --> 04:33.520
So in that paper, because all of our female walleye are tagged in the spring,

04:33.520 --> 04:37.520
and so we catch the same fish year after year after year.

04:37.520 --> 04:41.520
So every, in multiple years, you could get egg samples from the same fish,

04:41.520 --> 04:45.520
so you can look at how different factors have influenced those eggs,

04:45.520 --> 04:47.520
and then we can look at recruitment later.

04:47.520 --> 04:57.520
So we're kind of looking at that long-term kind of egg quality and maybe recruitment potential.

04:57.520 --> 04:59.520
How's the egg quality looking so far?

04:59.520 --> 05:05.520
Well, I haven't measured them yet, so I have to like take the photo and put it into the software,

05:05.520 --> 05:09.520
and then I do little measurements on 10 of the eggs,

05:09.520 --> 05:15.520
and then we can kind of look and see if per female, okay, how big were her eggs on average,

05:15.520 --> 05:19.520
how big were the yolks on average, how variable were they,

05:19.520 --> 05:25.520
and then we can kind of like, we can relate those back to, well, this year,

05:25.520 --> 05:30.520
what was the ice like this year, what was the ice like last year, what was the perch like last year,

05:30.520 --> 05:35.520
how are these things influencing eggs and potentially recruitment?

05:35.520 --> 05:36.520
Potentially.

05:36.520 --> 05:38.520
Yeah, so that's what I'm doing.

05:38.520 --> 05:39.520
All right.

05:39.520 --> 05:40.520
Yeah, I don't know.

05:40.520 --> 05:45.520
For about two years, you know, there are a few people in there that have seen 120 perch,

05:45.520 --> 05:47.520
you know, in and outing.

05:47.520 --> 05:49.520
There's still people, see them up.

05:49.520 --> 05:53.520
I actually haven't demonstrated to probably pick all the snacks,

05:53.520 --> 05:56.520
and then I'll be there after, and so,

05:56.520 --> 05:58.520
I'm going to move up to Samford.

05:58.520 --> 05:59.520
Yep.

05:59.520 --> 06:03.520
And like I said, everything should be there, both should be ready to go and guess stuff,

06:03.520 --> 06:09.520
and the hooks, you know, to tie off the boat is in the deep seat of the truck there.

06:09.520 --> 06:10.520
Okay.

06:10.520 --> 06:13.520
So, should we all have been going to go home for you in that quarter?

06:13.520 --> 06:14.520
Sounds good.

06:14.520 --> 06:18.520
Yeah, so I'm not going to get your leg.

06:18.520 --> 06:19.520
It doesn't take long.

06:19.520 --> 06:22.520
It's when something like that happens, and people are harvesting at that level.

06:22.520 --> 06:24.520
But it's going to be even...

06:24.520 --> 06:30.520
Well, the first thing I need this, you know, I've gone for a while.

06:30.520 --> 06:34.520
But it's one of the purposes of why I originally regulations were set up,

06:34.520 --> 06:39.520
so when I did open up the fishing, I think, you know, the natural mindset would be like,

06:39.520 --> 06:42.520
one, they're going to be absolutely loaded with fishing,

06:42.520 --> 06:43.520
and they're all going to be huge.

06:43.520 --> 06:45.520
It works the opposite way with fish.

06:45.520 --> 06:48.520
And so you have too many miles to feed, and so they were all almost done.

06:48.520 --> 06:49.520
Small with something.

06:49.520 --> 06:54.520
And so the no-close season, no bag of them, no size of them was originally put on

06:54.520 --> 06:59.520
to basically how much harvest does it take to kind of put that reflection on balance.

06:59.520 --> 07:03.520
Like Mack was talking about, he loves the fish some mama on that mallet.

07:03.520 --> 07:08.520
And his little dog, his little white dog, is dyed now, and he had those hard issues.

07:08.520 --> 07:14.520
But he'd be in here every two days, you know, older gentlemen dragging his canoeing in there

07:14.520 --> 07:16.520
and all his glory was a little dog.

07:16.520 --> 07:18.520
So you get a lot of that stuff, which is kind of cool.

07:18.520 --> 07:19.520
Yeah.

07:19.520 --> 07:22.520
You get to know people.

07:22.520 --> 07:23.520
Wernher.

07:23.520 --> 07:24.520
Wernher.

07:24.520 --> 07:27.520
Yeah, we get dirty old men in here.

07:27.520 --> 07:29.520
Big gals and stuff.

07:29.520 --> 07:30.520
You can imagine.

07:30.520 --> 07:31.520
Wernher.

07:31.520 --> 07:35.520
Here's another one he and his brother's brother's passing them up to,

07:35.520 --> 07:40.520
but they need to exclusively push it out.

07:40.520 --> 07:41.520
Yeah.

07:41.520 --> 07:45.520
So, I mean, this is the main building that was remodeled in 2008.

07:46.520 --> 07:48.520
It's all solar and generator-owned.

07:48.520 --> 07:51.520
We're completely not figuring it out.

07:51.520 --> 07:53.520
So, the big muskies, I guess.

07:53.520 --> 07:57.520
You know, all kinds of different species of animal work.

07:57.520 --> 07:58.520
Yeah.

07:58.520 --> 08:01.520
So, five history.

08:01.520 --> 08:02.520
Definitely.

08:02.520 --> 08:04.520
Yeah, most pretty much it.

08:04.520 --> 08:05.520
No, I guess.

08:05.520 --> 08:08.520
Oh, I have a section on YouTube.

08:16.520 --> 08:17.520
Yeah.

08:17.520 --> 08:18.520
Yeah.

08:18.520 --> 08:19.520
Yeah.

08:19.520 --> 08:20.520
Yeah.

08:20.520 --> 08:21.520
Yeah.

08:36.520 --> 08:37.520
Yeah.

08:37.520 --> 08:38.520
Yeah.

08:38.520 --> 08:39.520
Yeah.

08:39.520 --> 08:40.520
Yeah.

08:41.520 --> 08:42.520
Yeah.

08:42.520 --> 08:43.520
Yeah.

08:43.520 --> 08:44.520
Yeah.

08:44.520 --> 08:45.520

Yeah.

08:55.520 --> 08:56.520
Yeah.

08:56.520 --> 08:57.520
Yeah.

08:57.520 --> 08:58.520
Yeah.

08:58.520 --> 08:59.520
Yeah.

08:59.520 --> 09:00.520
Yeah.
