Both tanks look good and many are mating, but I see no offspring yet. I think having plants and algae established has helped.

I wouldn't add potato water, and I wouldn't be concerned about light hitting the tank, Near a window that's not in full sun most of the day would probably be okay. They don't seem to require much care. I've bailed a gal or two of water out of the 10 gal tank a couple times. It's easy to scoop up a scud or two when you do that. I have a small water celery plant in the 3 gal talk, and they like that. I would like to have several plants in the 10 gal tank too.

Thanks for the advice guys. I don't have any aquarium plants and really don't want to mess with the expensive ones, that I don't like anyway, from the local pet stores. I guess my experiment will be plantless. The 20 gallon tank is setup and ready for the new arrivals for when they come this week. I will try maple leaves as forage (presoaked to remove the tannins smile ). I also have a 5.5 I'm not using. I think I will set that up differently tomorrow as Plan B and feed with scrap vegetables from the kitchen. I will post pics of both tanks once populated.

FYI - My plants were volunteers collected from our ponds.

Well Done! Now THAT is the kind of plant I like! In the spring, I will try again to establish vegetation in my pond. Now that I have aquariums, I will be keeping a transplant or three for them! smile

The Gammarus seem to have stopped mating so maybe they are now carrying fertilized eggs?

I think I read somewhere that scuds carry their young in pouches on their sides so.....I guess you watch for scuds with saddle bags! smile

Update….

The Scuds arrived today. Must have been a couple thousand of them. They came in a breather bag which I’d heard of but never seen. No need to add O2 to the bag. Pretty cool!

I put probably 200 in the 20 G tank and another 40 or 50 in the 5.5 G tank. The rest I put in the pond where they disappeared immediately into the rip rap.



Here’s a pic of my 20 G scud tank.



Here’s a pic of my 5.5 G scud tank



And here’s a pic of a few of the scuds getting busy chowing down on leaves.

First ducks of the year showed up today. A pair of mallards. They spent about an hour with their heads under water in one of the areas of the pond where I stocked the scuds yesterday! cry

Beautiful specimens. They are bigger than I thought they would be. Which species? Can you PM me or share the source and how many you ordered?

Thanks

You can get them here (scroll down to freshwater shrimp):

http://www.habitatnow.com/store/shop/shop.php?pn_selected_category=19

They are gammarus but I'm not sure which species. As they came from Minnesota, there's a good chance they are gammarus lacustris.

I bought 1 cup with standard shipping.

Bill, thanks for the advice. I have some on order which will arrive Wednesday. I'm curious why they can only harvest Scuds and shrimp (like the PK shrimp that Carol Fattig sold in the past) through the ice. I asked Kyle at the Habitatnow store why they can't harvest other times of year:

His reply:


------------------
We can only harvest them through the ice as that is when they come up out of the vegetation and we can harvest them in large quantities. When they are down in the vegetation, they are hard to get to and cannot get large amounts. I cannot tell you exactly how we harvest them as that is years of research and development to be able to do what we do.

If you are harvesting smaller amounts, you can set traps for them (minnow like traps with smaller mesh and put something dead in it such as a fish) or you can use a net to get some out of the vegetation. You would be able to harvest shrimp that way, just not large amounts like 10s of gallons.

Kyle, PLM

-------------------

now I'm even more curious how they harvest through the ice. Maybe Carol knows? I don't want to take his livelihood away, but seems like this should not be proprietary protected knowledge but something that could help all of us as we stock our own ponds with them. I'd like to have some way of knowing if the stocking bunch survived or multiplied.

perhaps there is an attractant that brings them just under the ice? Food source? Irritant that brings them up?

It was disappointing that they didn't say anything about the size. It's sometimes surprising what reporters leave out of their stories.

Not surprising at all. Journalists aren't what they used to be. I've been disappointed numerous times when a story doesn't even say where an event happened.


If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.

Nearly all the Gammarus I had in the 10 gal tank have died. They seem to have disappeared rather quickly. I have no idea what happened to them. The ones in the 3 gal tank are doing better, but they're not multiplying. I put 3 from the 10 gal tank into another 10 gal tank. It's the one I put the Azteca in. I haven't seen any sign of them either lately.

The larger Gammarus species of scuds do not do well when the water gets warm usually above 75F. They are a cool water species.

Thanks for the input Bill. From what I've read, 75 might even be pushing it. I hope I'm far enough North for these guys (about 20 miles form Wisconsin). Maybe they can find cold enough water in the deeper parts (12 feet)of my pond to survive but, if not, at least I've learned a good bit about scuds. My plan is to hit a lake near me this spring to see if I can net some of a local species and, hopefully, a grass shrimp or three. smile

Sorry to hear that! Maybe the ones in your ponds are doing better.

FWIW Mine all still seem to be doing fine. Just for info...

1) My tank water is 68 F
2) Feeding only decaying maple leaves
3) Low air flow sponge filter in each tank

I wonder how RAH's are doing.....

My scuds in the warmer tank seem fewer, and neither tank appears to have babies.

I found this old thread this morning about scuds started by Cecil back in 08. Interesting stuff in here....

Update...

My scuds in the aquariums still seem to be happy and doing well. Spawning has pretty much stopped but still see a few. Females have disappeared under cover. I assume to hatch out the eggs and molt. Hope to see some little ones in the next couple of weeks. Pretty much from the beginning the water in both tanks has had a slight white cloudy look which I assume is a bacteria bloom from the decaying leaves. My understanding is that is a good thing as I've read scuds also eat bacteria and diatoms. I see them grazing on the sponge filters where I assume the bacteria is collecting in a heavier concentration.

Anybody else got an update? I suspect Canyoncreek has the best chance of success being further north.

If you have gravel in the tanks, you might want to look close. A few of mine have burrowed into my pea stone. The ones close to the glass that I can see appear healthy.
