Spawning Lamprey

7 posts in this topic

I took a walk down a local river today and came across these Lamprey in spawning mode. They were located directly below a bridge, so I had a great overhead shot at them. The biggest one was about 20" long and about 2 1/2" thick behind the head. Sadly, I didn't have a polarizer with me though. I might go back in the next day or two with a polarizer, and a pitchfork.

That's really neat. I had no idea they spawned up that shallow. You'd think that would be a potential way to try and control their population. They seem that they'd be very vulnerable to netting, trapping or something.

There have been successful attempts to knock down the population the way you suggest. Expensive, though.

Well, I went back today with a polarizing filter and the Lamprey weren't there. I also did some research and found out that our Dept. of Oceans and Fisheries, which is responsible for Lamprey control, will be treating this river in August. I'm not sure if that's because August is the best month for treatment, or just because that's when they'll get around to treating this river. I'm sure that they're very busy with all of the Great Lake tribs in Canada. Either way, on both sides of the border, they've been doing a great job of controlling these hideous creatures.

A shot from last summer. This guy was attached to a Lake Trout that I caught. He seems to be smiling in the photo, but I got the last laugh...

If they're not sea lampreys (which I am pretty sure they're not), they are native lamprey species. As nasty as they are, they are native, and the government is only trying to control the invasive sea lampreys.

I totally agree! They look like "chestnut lamprey" to me as well! If they are, they are an important part of the "natural" ecology!

I'm certainly not a Lamprey expert, so I did some research on the "Chestnut". Several search engines yielded results mostly from States such as Iowa, Missouri, Kansas, Texas and Alabama. Maximum size from the search results ranged from 8 to 15 inches.

    • I apologize if that came out wrong. The idea might very well be the best route to go. It's just that over the past 25 years or so I have seen many attempts to save a dollar that cost a buck and a half to do lol.    Here are my two cents. If you have a slab and you want to pour on top of it while keeping the same footprint that sounds pretty doable and could probably save some money if you don't have to change drain lines, run water, heat runs, electrical etc into the slab.   If you intend to tie into the existing slab and run zones of pex across the joint and have the new and old floors end up at the same elevation it still can be done. Some contractors will not want to mess with tying into and raising the elevation of the slabs and will prefer to start from scratch especially if you as the homeowner want them to warranty the finished product.  The critical thing would be to use enough rebar drilled into the old slab and have enough compaction and sufficient footings to make sure the slabs stay where they are without settling. That would make all kinds of problems with the pex.    Hopefully that response came across better.
    • It'll be interesting to see if the team plays a little harder in front of a different goalie. 
    • Hawg, I'm with you on this one !
    • Check and see if you have a video output on you device. You may be able to record to a digital device.
    • Just use plain old spray paint in a can. I've done it many many times and seems to stick really nice. Nothing special either I can't even tell you the brand because I have no clue. But as mentioned doing 2-3 light coats helps.
    • no expert here, but heat doesn't rise. heat radiates in the direction of least resistance (R value). warm air or water rises because it is less dense than colder air or water.  If you don't insulate you will be heating the ground under your cabin and the earth is a very large heat sink $$$. get some info from an expert in the radiant field as far as tube diameter, spacing, water temp, manifolds, length of runs, and so on. it varies on amount of windows (solar) ceiling height and room type (bed, bath, living area,  storage etc.). once you pour over the tubing you get to live with it. I did my own Home 15 years ago and got some good advise (wish I would have taken it all)
    • Sonar works from above, cameras need to be submerged. What am I missing here?
    • I've also had good luck spray painting PVC.  Biggest thing I found is to do lots of light coats, the PVC makes the paint want to run in a hurry.
    • I believe you can do this with the Lowrance HDS 9 and above.
    • I'll go with another loss in overtime.
