Did Somone Say Salmon?

For several weeks between mid-August and late-September, this was a very common sight at the Goodyear Dam on Bowmanville Creek, just a short walk from Frank's place.

salmon fins
Dozens of Chinook salmon (intermingled with a few trout) wait near the base at the fish ladder as they regain some strength and determination to make their way upstream to spawn. I recently posted about the ladder here, and at that time, indicated that I would tell you about the salmon transfer that took place at the dam, this year.

Human intervention was required as so many of the Chinooks have outgrown the fish ladder which was originally constructed for significantly smaller trout. The hope was to transfer as many salmon as possible before the end of September (their final number of transferred fish totaled 5,540 which exceeded their goal of 5,000) and then start construction on the new, improved and larger ladders.

Funds and time have posed a problem, and now the new ladders will not be in place before next summer. That's okay as far as the spring trout run goes as they're still able to use the old ladders. Hopefully the new ones will be in place for next autumn's salmon.

You're probably wondering how it is that people go about sending 20 to 30 pound (9 - 14kg) salmon up a dam. I had no idea, myself and so I headed over to the creek to watch the volunteers at work. Lucky for you, I brought my camera with me. Did you honestly expect otherwise?

Along the way, I noticed that these men were transferring the salmon in a different way - home to the dinner table.




fishing woes
Others were not going to be allowed to transfer them anywhere. They were caught fishing without a proper license and their vehicles and fishing equipment might well have been confiscated because of it.

But back to the transfer.

Dozens of volunteers came out on various days to help with the process. Before school began in September, many of those helpers were kids. They worked tirelessly to net, hold and carry fish that probably weighed about twenty to thirty percent of their own body weight. This photo was snapped in late August when the air and water were considerable warmer.




fish transfer19
It was a much easier catch for this guy than for the young girls. He seemed to be having a pretty good time.




fish transfer28
Another one nabbed.




fish transfer25
Volunteers worked together to transfer the fish from the net into a sack.




fish transfer33
Frank guesstimates this one to be at least 25 pounds (11kg)




fish transfer36
Once the salmon is bagged, it's hooked onto a pulley to make its way to the top of the dam. Now you know what the bird seed sack was all about in the previous post.




fish transfer13
Volunteers at the top of the dam are there to receive the fish, record the numbers and to weigh the ones they feel are particularly large.




fish transfer23
The salmon is carefully removed from the bag, placed into a basket and passed over to waiting hands in the water at the top of the dam. The fish is held in the water for a while as it regains its equilibrium - necessary after being suspended upside down for the trip up the pulley system.

One after the other, fish are handled in this fashion and then released. I witnessed many of them eventually slide right back down the dam. Perhaps some of those had already completed the business of spawning. Perhaps they were just too exhausted to make it. I hope that most of them did though.

Sadly, these numbers only represent a fraction of the fish which were trying to make it over the dam, this year. There are simply far too many salmon - more every year. They are probably putting a dent in the trout population, which is disappointing to many - especially the trout.


salmon roe2
And speaking of trout, the amber globes seen in the previous post was a close up of salmon eggs. The roe is often collected and kept as bait for trout fishing. When anglers are walking back to their cars with the salmon in tow, the roe will often spill out along the path behind them.

This less than two minute video shows the transfer process for one salmon from start to finish. Please keep in mind that I had a large, heavy lens on the camera, and when switched to video mode, it does not allow me to hold the camera close to observe through the viewfinder (my preferred means of snapping shots). I had to extend the camera and lens out in front of me to look through the live capture window instead. Therefore, there are a few portions which are quite blurry while I struggled to maintain focus and avoid the shakes. I apologize for that and hope you enjoy the video anyway.



More photos coming up in a few days.

Spawn-taneous Salmon

Frank lives across the road from a swift-running creek that pours into Lake Ontario. Every year, around this time, Chinook salmon make their way from the lake, up the creek and over the dam's fish ladder to spawn. The ladder was built for trout which travel the same route each year - many of those in spring. Salmon are considerably larger than trout and these guys, some weighing close to 30 pounds, are simply becoming too big to make it up the existing ladder.

The community raised funds to build a bypass channel. and work was to get underway earlier this summer. As with many well-intentioned plans, the work was delayed for one reason or another and before they had a chance to begin, the salmon began making their way to the ladders to jump. This was in late July - much earlier than their usual run.

Since so many of the salmon are unable to make their way through the ladder, plans were made to net the larger fish, and lift them over the dam, into the channel above. The hope is to transport up to 5,000 fish in this manner over the next few weeks.

Of course, many of them are small enough to keep on trying their way through the ladder. I snapped these photos when the crew was still setting up their station, but not yet actively transporting salmon.


upstream
In the days preceding their approach at the dam, dozens of salmon were working their way upstream. Those tails can really propel them against the current.

Fins and tail are all over the creek - almost giving them the appearance of sharks.




jump17
Every now and then you can see one of them flip up in the air. Frank took a look at this photo and pointed out that there's a lamprey eel also seen in the above photo. And here, I thought it was a piece of pipe sticking out of the cement wall.



The next few photos will illustrate how difficult it is currently for these fish to find their way up to and through either of the two ladders.


jump9
This one made it up onto the concrete dam in between ladders.




jump14
Most of them will eventually right themselves and work their way back into the water. Others will perish on this platform.




jump13
This one overestimated his jump and landed above the ladder with a sickening thud. He was back in the water in just a few seconds to rest and then try again.




jump3
There are occasional mid-air collisions.





Some of the time they get it right. Here's a very short (12 seconds) video of some jumps.




jump
This one made it.




jump8
As did this one.




jump7
And this one.


Of course not everyone is there to watch and photograph the salmon. Some are there to catch them. Many of those will also release their catch.


catch release2
I watched as this young boy caught and released this Chinook.




catch release4
He carefully removed the hook and lifted the salmon over deeper water.




catch release6
He held onto it for a few moments to allow it to regain its strength and equilibrium, and then released it back to its freedom.


Now the downside of all of this, is that not every fisherman is as caring and conscientious as this boy. Some leave the carcass on the shore after removing her eggs (to be used for trout fishing). And many salmon simply do not make it to their desired destination. The result is a very smelly walk alongside the creek. And as much as I don't care for the scent of decomposing fish, Benny kind of feels the opposite way about it.

While I was busy photographing some of the above images, Benny was busy getting up close and personal with a dear, departed fish. And by that, I mean that he took great delight and pride in rolling in it.


rinse
It's a good thing Benny likes to be in the creek. He needed to rinse off some of the excess Eau de Poisson.

And when he got home, a much needed shower was in order.


I hope you enjoyed watching the salmon with us. Before too long, I'll have some photos of the salmon transfer for you.
