Thanks for the trout info, it will assist in my plans next year. I would like to say it was my pleasure to have met your wife @ Brian's place this past fall. She must be a keeper because you guys have been together a long time and that is good. Now for me and my experience, if you can keep a woman happy, you are a better man than me smile

Thanks Tracy. I've been reminding her for over 30 years that she's a temp, but I'm not sure she believes me. I will say this about her though, she's creeping up on the big 60, and she can still pull her end of a seine with the best of them.

The trout have been fun.

Dropping the brood pond 3' today to get ready for Sunday's seine. This last week's weather has made the draining problematic since I didn't want to drop the pond with warm water. Increased crowding, warm water, and potential decreased DO due to the RBT crowding, all made my decision easy though. I was waiting on this cold snap to lower the water temp, and it hit perfectly. Yesterday at 04:30, the outdoor air temp was 68 degrees. This morning, it bottomed out at 31 degrees. I think that's low enough to hold the colder water until Sunday, and all should go well.

I've also been taking almost daily water temps at the surface, 3', 5', and 12' down. What I found was that once I hit 3', the water temp remained the same all the way to the bottom of the pond (12'). I also found that wind affects the surface temp greatly. Basically, the stronger the wind, the quicker the air temp drops or raises the pond's surface temp. Knowing that gives me options.

Since I already have the 3" water pump set up to drain the pond, I wanted to figure out a quick and easy way to take advantage of the warmer or lower subsurface water temp depending on whether I needed a slightly longer season for cold sensitive fish like tilapia, or cold weather fish like the RBT. I think I figured out a way to do this, and aerate the pond also. It only took a few pvc elbows I didn't already have, pvc I had laying around, and some quiet time to think. Whether it has merit or not, is something I won't know until I try it. I have to admit Cray's post about his LMB dying started all this. I sure hated it happened to him, but it made me realize I had no contingency plan if this same thing happened to the RBT. I hope I have one now.

I'll post some pics once it's set up, so when I do, please kick it around all you want. Won't hurt my feelings one iota, and I built it all with male/female fittings at the end of the pvc pipes, so changes only require altering or replacing the actual end pieces.

Al, what were the water temps at the depths mentioned in the big pond and the brood pond? And are you talking air in the brood pond, I thought I remembered you not having aeriation in the big pond? With u using pvc for air in the brood pond, are u talking about a fountain made from the pvc? And are u adding the trout now to the big pond to feed the lmb? What do u expect to see when u add the rbt to the big pond? Inquiring minds want to know smile

Tracy, yesterday morning the brood pond was 59 degrees on the surface, then 54 degrees on the rest. The big pond is very different. It's probably a 1,000' or more from the dam to the top end of the pond, and those surface temps fluctuate as much as 4 degrees. When there's no wind affecting it, the shallowest water at the top of the pond is usually warmer. If you're asking for the reason I think you are, then I'm no help on the LMB spawn. The big pond has been fluctuating from between the upper 50's, to the low 60's for weeks now, and I've seen several beds that were stopped, and had neither LMB or CNBG on them. I've seen no new beds at all, but I sure wouldn't bet against that changing week after next, if it hasn't all ready.

Yes, air is for the brood pond. I see no scenario where I'll ever add it to the big pond because of $$$$. It is kind of like a fountain without the throw, but the addition of air at the pump, and the ability to pull water at any defined level gives me options. It'll make sense once you see it. I'll post my initial thoughts, whether it works or not.

The only real goal I had in 2016 and then this early spring, was to see how many months I could grow forage with no legacy fish left in the pond. The tilapia died when it got cold, and now the trout will die when the water warms up. That means no draining, seining, and killing out the pond before this year's project. Best I can tell, I'll get 9-10 months of forage growth, with no residual fish.

As far as my goals specifically with the RBT, they're purely informational and recreational. I'm by the brood pond 3-4 times a day, and I enjoy having the more immediate results that a smaller pond provides. Will these trout add weight to the LMB? Sure they will, but let me throw a few numbers out. Just for round numbers, let's assume I have 50 LMB per acre, and 25 of those are capable of eating an 8"-10" RBT. On my 11 acre pond, that means I would be feeding 300 LMB. At 10 pounds of forage for a 1 pound weight gain, I would need 3,000 pounds of RBT to make a difference. Add to that the short period that they may even live in this pond's warmer water, and I think the benefits would lessen greatly. It's like the difference in eating a huge steak, and needing to let your belt out, and eating 4,000 calories a day for extended periods. One adds long term weight, and one is temporary. I'm ok with that.

Tracy, the plan right now is to dump 5 gallon buckets of RBT for several days, and then stock the rest in one drop. When I do that, my hope is that carnage ensues. The only obvious issues that readily come to mind might be the rising water temp, which further shortens the RBT survivability, or if the female LMB are on the beds when the RBT are put in. If they're on the beds, then they'll most likely miss their trout treats.

Thank you for your answers. sorry if I asked too many questions. You have been growing fish a lot longer than I have and I thank you for passing on your experience. And yes it would be very expensive to feed steak (trout) to your lmb every day. Todd asked me if I wanted some trout this past fall and I passed. My thinking was to hold off till next year when the lmb might need the extra calories. There may come a point where forage may be reduced and the trout could help, if I could afford to add them for more than a snack. And as far as the lmb spawn, I think I may be looking at late March. Thanks again

Tracy, always ask away.

So as I'm apt to do, I overthink the simple things. I hooked all the hoses up, and it was a disaster because of the back pressure the flexible outlet hose caused. Any kink, and water went everywhere. Luckily I was alone, so no one saw it. Putting the most air possible at the pump outlet was my main goal, so I removed all the hose and and restarted this at the pump. I think that's all I'll need, and I'm not sure how I could add any more air than this to the water. I did float the inlet so it wouldn't pull silt up like it tends to do when it's laying on the bottom of the pond.

The riser is on the wye because of the small amount of back pressure in the outlet pipe. With my 3" pump, the water churned and rose 16" up the riser, so I left 10 more inches of head space, and all seems well. I hope I never need this, but if I do, it'll jut take a couple of minutes to set up.

Any thoughts? What am I missing?

Looks good to me. Might shoot the water at an angle to the bank so it causes a slight current around the pond to circulate.

My back up plan is a brush hog type mower set where the blades just slightly touch the water, running the tractor at modest speed.

I like it, I did not realize one could have an air suction vent that size in a 3" discharge. looks to be adding quite a bit of air. Would have been nice to see the water discharge with and without the air input. Could be done by placing your hand over the air intake and then without the hand. But yes I think that will get you out of a bind, if needed. Thanks for the pics

Tracy, I did hold my hand over the vent stack, and there less suction than I had hoped for. Highflyer called last night with some recommendations, so I'll change some things up and repost the changes. My head spins when he fires his big brain up, but it was something about velocity, and pipe diameter while eating pie. I might have been distracted when he said that though.

He's helping me run some carrying capacity tests later this spring, and he's bringing his DO meter with him. We should get some solid numbers then.

Strong work Al. You're on to something there.




What kind of pie? Did he mention meringue? I hate that icky, fluffy stuff.

Sorry buddy. No help on the type pie he mentioned. I remember something about it being square though. Isn't that called a cobbler?

I've started my 2018 long term CNBG project, so I wanted to finish up 2017 first. As per usual, we had major rains in late spring, and the brood pond blew out again. Since fish moved both in and out, I decided to add 30# of FHM's, and 20 LSL LMB fingerlings. I seined the pond around the end of November and gave all the BG/CNBG to a cousin with 3 small ponds. The LMB were tagged and released into my big pond.

The LMB did not get the growth that I had the last time I stocked them, but these fish were there to just clean up fry and fingerlings of mostly unknown origin. When the pond was dedicated to the LMB, and stocked accordingly with FHM and gape friendly tilapia, the growth was very impressive. The LMB in late 2015 grew to over 2# in 180 days. Few of 2017's crop were over 14oz, but I expected that. At the end, they were scavenging at best.

When all the fish were pulled in late November, it was time to drain and treat the pond with hydrated lime and get ready for 2018. Unfortunately, I fired my seining partner, so I had the pleasure of doing the seining of this pond by myself, which was a first for me. Surprisingly, there were very fish that I missed. The seining part went no differently, but the trudging up and down the silty banks to slowly pull the net only 4í per side was a PITA. I burnt a few calories that day. Oh, my seining partner didnít divorce me after I fired her.

I've had this little pond going for 7 years now, and I decided to return to it's roots, and that would be growing out new CNBG genetics to add my big pond. I'll readily admit that when this all started, I couldn't tell the difference in a 3" greenie, and a CNBG. A lot has changed since then. One of the things I've learned over the years, is that certain projects take different amounts of effort. Refreshing genetics is one of those projects. Because of that, the pond had to be void of any living thing prior to restocking.

Here's how I handle hydrated lime when things get serious.

This is the pond before and after spreading hydrated lime. The pond was drained until the pump started pulling a vacuum. Less water means less hydrated lime.



Don't forget to treat any potential areas that may hold both water and fish. The fish in this picture was 30' above the pond in a small rut. It had been 2 weeks since any rain, and the BG was still kicking when I found it.


Pipe inlets and watershed often have washouts and can hold fish, so be sure and treat those also.



Never ever forget to treat footprints. You'd surprised how many fish they can hold.

Great advice! Those pesky little bluegills can hang around in footprint rather easily. Some of us have learned that from experience!
