Bruce, BSF would probably work for about 4 months a year. Will RES eat them?
Just do it...

If we accept that: MBG(+)FGSF(=)HBG(F1) And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1) Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT? PB answer: It depends.

My 200 YP YOY in less than 200 gallons of water are now pushing 10 inches. Not sure one would even get that in a pond.
Higher water temps also make the fish hungrier and more apt to feed train.
Cecil post pics of those YP if possible. Each fish species has a temp range from low terminal to high terminal. Within that range feeding and growth max at different points but not anywhere near either lethal extreme. To a point within that optimum range feeding activity is usually a little higher just below the max growth rate point which is well below thermal max. So higher water temps are good but only so far. Cecil I know you know the above so it is intended for others who may not know about fish being cold blooded and how their growth , feeding and metabolism work. So your point is Bruce is trying to grow his redears in lower water temps to outlive us all? Sorry couldn't resist. My perch are grown out in 75 to 77 F. water btw.

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

Bruce, Keep tabs on what's happening between the two tanks. One being plastic and the other being galvanized. Generally, one would want to coat the inside of a galvanized tank with an epoxy, or like material, to avoid the potential for Zinc poisoning. If all you're doing is changing out a bit of water every day, with no real filtration, get a cheap TDS meter.

From what I have read galvanized may not be a problem in medium ph water that is not too acidic or alkaline but it's said not to take a chance. Come to think of it the fish do seem to have a shinny galvanized sheen to them. From my experience with galvanized tanks and epoxy though (even with acid etching etc.) the epoxy eventually deteriorates somewhere and allows water underneath it. You're better off sticking with plastic or fiberglass if you have a choice.

Do you guys really think the zinc could kill my fish? Do you think my water exchange rate affects that? How would I know if problems are developing?

I could have no effect, slowly leech and be a stressor, or kill them. Hard do to say as it depends on your water chemistry. Most aquaculture sources say to stay away from it or coat it with something. Many sources say not to even use zinc in small fittings.
What is your PH?

Crap. Well, so far, after about five weeks the fish are feeding VERY vigorously. I hope that's a good indicator.

I know next to nothing about aquaculture, but I think your stated goal of total water replacement every two weeks would surely help reduce, if not eliminate, any potential health issues due to exposure to zinc?

That's what I'm hoping, but it's sure got me on guard looking for signs of toxicity.

Don't brush that off!!! The main reason that Aquaculturalist don't use galvanized tanks, is because ya should be cleaning them from time to time to get results, and a scrubbing could easily release the oxidized material into the water that your filtration could never eliminate. You don't have a filtration system, but you would have to be on the fine micron level and hope it hasn't gone dissolved. Just don't disrupt the inside tank surface, like you would do a root scaling, or even brushing your teeth. Difficult to post stuff sometimes. I'm going to Walmart and watch the people

Phil, Ya know there is no cleaning from time to time with dual flow bottom and side drain self cleaning circular tanks. Have fun at Wally World. I stopped shopping there after my sibling started working there. The Walmart family owns 40 percent of the nation's wealth but employees can't get more than 32 hours a week and qualify for food stamps.

There is always cleaning, and that crap your talking about ain't worth 2 cent's I need to get to Walmart before all the electric rigs are taken up! My neighbor said, all ya have to do to get one of the fancy rigs is to just jump on one and take off. No need for handicapped credentials Just kidding tho. I do have to pick up something they have a good sale on.

Here's my current assessment of the palatability of various items.
On a 1 to 10 scale based on how agressively the fish eat.
Nightcrawlers: 9 Red wigglers: 9 Dried black soldier fly larvae: 2 Frozen blood worms: 10+++ Pellets: 5 (but better as the water warms) Fathead minnows: 1

[quote=JKB] The main reason that Aquaculturalist don't use galvanized tanks, is because ya should be cleaning them from time to time to get results, and a scrubbing could easily release the oxidized material into the water that your filtration could never eliminate. Phil, Ya know there is no cleaning from time to time with dual flow bottom and side drain self cleaning circular tanks. Riiiiight. Actually you do know all the surfaces in a recirc system are places for autothropic bacteria to grow on right? I saw one figure that said up to 30 percent of the surface area for it to grow on is on tank surfaces. So you don't want to clean too well. That's a common mistake for aquarium newbies. I also find messing with the tanks stresses the fish. It's amazing how clean my circular tanks are with the bottom drain and fish swimming around to move solids to the bottom drain. One pull of the slide valve on the external stand pipe and it's out of there! Just like a toilet! Of course my trout tanks will have continuous flow out of the bottom drain. My trout large trout tanks will have a bottom center drain that will flow via gravity continuously about 10 to 20 percent of the flow to a parabolic sieve filter to get the larger solids out of the system almost immediately, instead of sitting their polluting the water. The side drain will also go to the parabolic sieve filter. Then the flow will to a rotary drum filter and on to my low head rbc's. After that it's a sump tank with airlift tubes and a foam fractionator and back to the tanks via tpr's (tangential point returns). All DIY except for the rotary drum filter and sieve filter. Tanks will be low cost Intex pools.

Just got back and all the electric rigs were spoken for, crap! Neighbor was outside and said my timing was way off I did pick up some Bacon Flavored Spam that was on sale tho. The gal at the register wondered if I like that stuff? Said, don't know? We'll find out when there's no food left

Wow those bloodworms must be something else! RES absolutly love freshly thawed bloodworms! Likeabilty with fathead minnows is all about size, the smaller "pet shop" minnows are much more likeable than the slightly larger small "bait shop" minnows. My 7" aquarium RES show a very strong preference for minnows under 1-3/4" in length.

You're absolutely right about the size of the fathead minnows being the primary factor. Redears will not beat up a minnow to eat it. It has to be quick and easy. Bluegill will just pound them into submission.

Bruce, from the look of all the psychedelic lights in your fish room, I think it may be a good idea to do a random drug testing also! Please don't tell me you have continuous Hendrix and Joplin playing in the background!
Give a man a fish, and he will eat for a day. Teach a man to fish and he will sit in a boat and drink beer.
