What do yo do to keep your trout tank water cool?

Started by Tom OBrien. Last reply by Lisa O'Toole Jan 4, 2015. 23 Replies

Do you try to cool your fish tank water? Or do you just monitor the water and maybe feed less when the temperature goes up? I've got the fish tanks in the basement so they aren't seeing the 90 degree…Continue

My system has 5 FT ibcs. Two are 330g and three 275g. I divide my trout about 25 ea into the two 330s.

I see no need to crowd them (also for the size reasons posted below). Right now I have moved the remaining trout (about 20) into the 330 with my recycling biofilter which makes a big difference to their water quality (need to make 2 more, one for the other trout tank and one for our soon to be completed 4ft x14ft float bed). The 2nd 330 is ready to take 50 more fingerlings which will be divided again once the original 40 are harvested. (what we started with our first time around last Fall) Keep in mind the delicate nature of trout in terms of handling them. I lost 2 when I moved them all to the one 330. Floating but still very fresh the next morning. Once again they were not the bigger fish. They seem to not only be faster growers but also healthier than the slower growers. Things you only notice with experience. The 3 new Manx kittens enjoyed those 2 so no great loss.

Might be a good way to separate the faster growing fish from the small ones as they grow. I saw a lot of aggressive behavior in my little 150 gallon tank as the fish grew. I found a trout behavior study that linked slower fish growth and losses to populations of mixed size. The larger fish got most of the food, but grew more slowly because they expended energy attacking the small fish.

I'm considering adding a 150 stock tank in my system. It will help me a catch drain and would dump into my 300 stock. How do I maximize the use of this tank beyond a drain? Could I use it for the smaller trout and then swap populations every 3-6 months? Thoughts appreciated. Thanks.

Jim,

6 out of what # total population? I have a 300 gallon tank and I was thinking of starting with 50 or so (factoring in attrition).

You won't be disappointed. We had our 3rd harvest of 6 just the other day. Very tasty indeed. My water temps have hovered between 68 and 73F all Summer and they seem very happy. Well, up to harvest time anyway

Ok, it's official...rainbow trout! Got my "stocking permit" from State fisheries today. The State hatcheries do not sell to the public, but there are 2 private hatcheries in the State selling Rainbow, brook, and brown trout.

Here in the NE TN mtns. they seem to be rainbow and brookies. Some are very pale on top and others very dark. We take whatever he nets out of the runs at the trout farm near here and they all taste delicious and take about 6 to 9 mos to mature. Some just seem to grow much faster than others and are healthier in general. Seldom loose a big one. Generally one of the slow growers and rare at that. I transferred all to one tank a week ago and found 2 floaters the next day. The kittens had fish for dinner. I believe it is more a bully thing and typical leadership roles more than anything that determines which get bigger faster. Both colors seem to have fast growers and slow growers.

They seem to be the same types we caught on Moosehead Lake in N ME from whence we moved 3 yrs ago. You should have no problem raising trout up there as our weather and ground water temps here are pretty much the same and trout have been our most successful species over cats and BGs. This summer I have simply used the artesian well water to cool things down the few times we went to say 73F max water temp. Here we are in Aug. and our night time temps have been in the 50's. Never got a hot spell so far and today we will be setting up the woodstove in the new house as mornings are damn cold lately. So much for global warming around here. I fear a very harsh winter is around the corner.

I think they are the most commonly farmed trout. They grow fast and they're delicious. I might still be growing them if I could keep them alive.

Are Rainbow Trout the most popular trout in AP?
Comment by Blue Hiller on August 15, 2013 at 2:51pm
Spoke to Maine Fisheries Haatchery Director today. Apparently he has inspected 4 AP systems (all tilapia) in the last 2 weeks. They seem concerned about non-native fish, thus conducting onsite inspections. He said I could get a permit ($5 for 5 years!) for a stocking permit for either trout or YP.
