Hous everybodys trout holding out with these high temps my tanks got to 24.4 then i put a sprinkler over the whole system for 1 hr dident drop the temp but it dident climb eather now ambient has dropped from 36 to 29 in the last 1/2 hr now a few cooler days then hot again next weekend

Only got one small trout in the sump of my bigger system. It survived the water getting to 27C the other day, dunno how. He shot out to grab some food this morning when I fed the yabbies. Got a 50L/min air pump in this system with 4 X 100mm air stones in the fish tank and one in the sump

Still have about 20 good size trout left in my system. System temp is still rising, currently 22.3, as it normally peaks early evening. Ambient temp is down to 27 and falling so hopefully all should be OK with a cooler night to drop temperature

56 still going strong. Water temp has reached 25C at times and they stop eating at about 22C. Current water temp 20 and they've just had a good dinner.

Got about 30 in 3000L ATM, fine and dandy, but it's been down right cold here.

Going to be hard to keep them going with some high minimums coming as well here in Perth.

So does anyone in Perth still have trout? Would be pretty amazing if you still do after this weather... Not so much the high day time temps, but the high minimums are a killer, doesn't allow anything to cool down...

Sunday Very hot. Partly cloudy. Min 25 Max 38
Monday Partly cloudy. Min 26 Max 35
Tuesday Sunny. Min 24 Max 37
Wednesday Very hot. Sunny. Min 24 Max 38
Thursday Sunny. Min 24 Max 37
Friday Partly cloudy. Min 25 Max 37

bugger me . . and i dont have aircon

all the more incentive to stay at work i guess. . .

I've still got some!!!
Though I'm not in Perth the temps have still been high and have experienced 2 degree rises in most tanks over the last week.

TM are you planning on doing a run up here with trout and SP this year? i am interested in getting my hands on some fish from you if you are also when does everyone think they will be putting trout back in? Aprilish?

Fb, hope to start bringing trout up from early April if the weather has cooled down enough. The only SP I have are still tiny so I intend to grow them on in heated tanks over winter before making them available for sale.

thankis TM, i will PM/ contact you before then

My FT temperature reached 29 yesterday and this morning, I have fished out 7 dead Rainbow Trout. I can't see any others surviving after this.
This is despite having a fountain running continuously in the FT whenever FT ambient temp is above 24°C.

As Joel said, the high overnight minimums have prevented the FT cooling down and the High RH prevents the fountain from having much effect on temperature.

Same scenario got me on the Holmes-A-Court site... bugger was the day after... the tank dropped back to about 22... about 20 the day after, and since.... below 20.....

Yep , I lost 1 of my troopers today , just to high temps for to long .

Rest are coming out today , no point wasting them I spose .
