Re: Relative weight charts in Excel ? Calculations?
esshup
2 hours ago
But, look at the charts that are in the archives. Take LMB for example. A 22" LMB should be 5.9#, a 23" 6.8#. If a 22.5" LMB is much either side of 6.3#, how critical is that to figuring out the RW? You are looking for trends in the pond, not absolute numbers down to the 3rd decimal.
Say you have 2 different 22.5" LMB One weighs 6.3#, the other weighs 6.5# because it just recently ate a 7" BG. Will that 0.2# be enough of a weight difference to make a decision to change how the LMB are managed in the pond?
What I'm trying to say is that once you start managing ponds in the real world, it's not critical that the numbers are spot on because of all the variables that are in the pond. You are looking for trends, and the 1" weight change is fine enough of a measurement to see trends.
Please do the power function calculation on a LMB that is 22.25", 22.5" and 22.75" and list what the weights are. How much do they differentiate from the weights calculated from a linear function?

Re: pond experience needed

Jeez, I'm sorry to hear about your ordeal.
O.K.If the clay can be moistened and rolled into a pencil shape between your palms, it's good enough to seal the pond. If not, see if you can find better clay there. Stockpile the good stuff. You will need enough to cover the whole pond bottom and sides 18"-24" thick.
Cut the sides back 3:1 or 4:1. You were absolutely correct about the slope. You should cut the bottom/slope/sides 18"/24" deeper than the finished dimension. Beg, borrow or rent a sheepsfoot roller (not a smooth barrel roller).
If you have good clay in the bottom of the pond (see above) then run the sheepsfoot roller over it and let it "walk up" off the material, then take some of the good clay that you stockpiled, spread it out 6"-8" thick all over the pond bottom/sides. Run the sheepsfoot roller over it again until it compacts it and starts to walk up out of the clay. Repeat that 3-4 times so you have an 18"-24" thick layer of clay all over the pond bottom and sides that have been sheepsfoot rolled.
If you find areas of soil that are sandy or permeable (iffy for sealing) dig them out at least 24" deep and sideways back into good material, take the stockpiled good clay and pack it into the iffy area that you dug out.
Yes, it's a lot of work, but it will be even more work if the pond isn't sealed. You will have to play with water content of the clay to get the "pencil" and then you will have to try to duplicate that moisture content when you start sheepsfoot rolling the clay.
A smooth barrel roller won't work because the layers need to be "knitted" together to hold water and stop it from traveling between the layers.
Dig it wider I think that will be easier than trying to put the dirt back and trying to compact that dirt on the steep slope. You can't put a few feet down and compact it, the lower layers won't be compacted.

Re: New pond middle TN: establishing food chain?

BJ for your current planned fishery stocking, when using the correct numbers of fish stocked, you should not encounter forage fish shortages in your 1/4 ac pond. When a pond gets out of balance of fish numbers is when growth rates of fish are slow. Your current plan without feeding pellets is for a "good" fishing pond (not focused on developing lunkers), AND a fun swimming hole that visiting family/kids will enjoy. Good swimming pond means doing your best for introducing fewest nutrients as possible for the natural soils where the pond is built. All nutrients that get into the pond usually results in increased algae and plant growth. BJ Look at this UT website about the nine soil fertility regions of Tennessee. Try and figure out in which region your pond is located. This information will help determine the natural carrying capacity of fish and numbers to stock for your pond. https://utcrops.com/soil/soil-fertility/soil-ph-and-liming/

Thanks, you guys! I've waited 68 years to be 69! HB Bob. So 69 was the target? Mine was 65 so I could get the $2 senior discount at the local all you can eat catfish restaurant.

Re: Working on a .5acre disaster, I mean pond.
PRCS
Yesterday at 11:39 PM
This land no matter what will need a liner whether it is clay or Poly. There has been further development of the garden that has taken up the place now where the pond was supposed to go.
My thought is I need to lay in something beneath the liner. But concerned about just using Sand.
Also on top of it all there wasn’t anything ever installed for overflow prevention.
The company has purchased water tankers to help fill the pond for an event.
With enough “water redirection” I can send the water to the pond. My obstacle is right now prep for liner the overflow isn’t anything big for me to think about.

Re: Fungus infection on fish

I had a rash of fungus infected fish a couple years ago. Seemed to be caused when I over fertilized the pond but there wasn't enough alkalinity for a bloom.

Re: 1 year after stocking question
esshup
Yesterday at 09:48 PM
How many more bluegill and forage fish would I need to support the predator fish? See my post above your question. That is where my answer is. Look at the ratio I put there. The bigger number is the number of bluegill you should have stocked for every LMB. Here's some math for you. A single LMB needs to eat 10# of forage fish to gain 1# in weight. That's when they are young and small. As they grow in age and weight they need to eat more and more fish per year just to survive, and way more fish to put on 1 pound in weight. Think of a human. How many calories do you need to eat per day to stay the same, vs how many calories a baby needs to eat to stay the same weight? Fish are no different. A LMB needs fish to eat that are roughly 1/4 to 1/3 it's body length or it's wasting too many calories chasing down smaller fish to eat. A LMB does NOT catch a fish every time it tries to, so that is more wasted calories. You stocked 75 2"-4" LMB. At that size, they need fish in the 5/8"- 1.3" range to eat. As they grow the fish they need to eat have to be proportionately larger. Bluegill that are 1"-2.5" in length weigh 3-9 pounds per thousand fish. Bluegill that are 2.5"-2.75" weigh 10-14 pounds per thousand. Bluegill that are 2.75"-3.5" weigh 15-24 pounds per thousand. So, with that information you should be able to do the math and figure out how many fish you need to add, and what size they need to be..

Herons will destroy a pond and eat your fish, I have had them kill bass and not even eat them just kill them. Destructive birds and they sure are not endangered like vultures they are way to many of them. .17 hmr works nice and quite

Re: Brooder Shiners and Fry, What to do??
Freg
Yesterday at 02:42 PM
Per the recommendations of others in this thread, I think my game plan is that once I get a hatch I will transfer at least 100 out of the 130 brooders to my main pond as well as most of the fry. If I never get shiners established in my main pond that's okay, I just wanted to have a way of breeding the shiners to at least supplementally stock into the pond as an additional food source.

Re: Reducing fish biomass
FishinRod
Yesterday at 01:18 PM
One of my buddies in med school did a research project where he had to pith the fish and then take the samples immediately after the fish died. It was the same method.
He was a VERY precise guy, and is now an eye surgeon, so I suspect he got it exactly right every time.
I suspect I might miss every now and then, but I believe it is considered one on the most humane methods to euthanize research animals. Like our "taste" experiment, you typically don't want stress chemicals in your research animal tissues.

Last year just feed a low quality food periodically 4-5 times a week, Plan on High Quality feed with Automatic feeder this Spring. Just a "Broke Teacher" here, Thanks guys, I try to keep my eye on it closely. There have been some Hiccups, but things are headed in the right direction.
