new fish pond temp?

[slick]

At what temperature should the pond water be before new fish can be introduced? im talking about new young koi of around 5 inch new stock? many thanks for reading all info is taken on board

When I picked up some fish one year, the dealer said wait until the water was consistently over 60F. Not sure with koi, that was shubunkins.

I think it depends on the temperature you have him in right now. I once introduced new goldfish to a 48 F from 72 F last year, he lives. But I cut corners and that's not the way I would suggest you do it.

Here's my topic about it. Look for Dave's and Shakaho's replies and follow their advice. https://www.gardenpondforum.com/threads/when-to-move-indoor-goldfish-outside.13714/#post-209209

Good luck.

Thanks for that I work in degrees c but I can convert it via the net but all info is good info

Stress will be minimized at 20C.

Sorry Meyer but we are talking the UK here my friend not Florida your looking more to a temperature of 15c rather than 20c we are luchy if we see 16c tops in some ponds during the summer months mine in a bit of a sun trap at a push can hit that of 22c at a push 24c and I mean at a push

Really?? 20C is the lower temperature of the range for homeostasis in Carp (Cyprinus carpio).

This is the accepted temperature for heat ramping koi to bring out the CyHV3 virus in koi note they go in at the temperature of 15c and are artificially raised to past your temperature range then down again to 15c etc.:-

http://www.koipolloi.co.uk/about.php

Koipolloi are signed up to the fight against CyHV3 entering the UK but honestly we are lucky to see 16c in our ponds normally during the summer months .
Even at our clubs show in Mid to late July the water temperature of the show Vats are only normally 16c , we pay particular attention to matching these temperatures and allow 30 mins for the temperatures of the water in the bags to match that of the show vats
Just so we dont loose slick in this Meyer homeostasis is the ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes.
Meyer if you recall weve talked before about Carp and regional variations in temperature and how they adapt to them and why they have taken over much of he globes bodies of water and succeeed when introduced ?

Talking of enviroment Meyer I take it your native to Florida my friend yes ?
I remember as a young sailor enjoying an afternoons surf canoeing off of the beach at the Naval Air station Mayport Florida where the temperature was that of winter.
A Floridian thinking we were totally crazy doing came across to talk , in his veiw it was winter , the temperature was in the mid 60's F when we told him back then that the mid 60's f upwards was a British summer back then (before global warming started to ratchet up temperatures) he walked away saying you guys shaking his head laughing still convinced we Limey's were crazy..
A few weeks later and it was in the 80's f

In Yorkshire it never gets higher than 22*c ! No I mean it! When it gets to 22*c old people pass out and die, and people panic buy fans and bottled water!

Let me be more specific. 20C is the lower temperature of the thermoneutral range for homeostasis in Carp (Cyprinus carpio).
In other words, it has been shown that minimal energy is required to maintain homeostasis is Carp within the temperature range of 20C/68F and 34C/93F. Homeostasis can be maintained outside of this range but at ever increasing energy costs as the temperature differential increases.

http://www.biolbull.org/content/112/1/97.abstract

If one looks through scientific literature devoted to research of Carp, they will find that the water temperature maintained in during research is 25C to minimize any effect that temperature may have on the research results.

Humans have a thermoneutral zone. Well, actually two (2) if you happen to be a Naturist.
"The thermoneutral zone of a naked human is 28‐30°C while the thermoneutral zone of a clothed human drops to 22‐25°C which represents conventional “room temperature” "(Lodhi and Semenkovich,2009). Outside of this range a human reacts either by increasingly shivering or sweating as the temperature gap widens, both are external signs of the human body striving to maintain homeostasis.

Well I didn't know that, im a bit relieved about what you're saying, as I have a indoor aquarium housing this years pond stock, I bought the fry at a knock down price at the end of September, and raised them in doors throught the winter, best of both worlds cheap koi and I can sit on my sofa watching kok, any way even with no tank heater the water is at 22*c this is why im asking about pond temp, as when will it be safe to take them out of the aquarium (at 22*c) and safely let them play and grow in the biggish pond?

Considering your geographical location and the seasonal ambient temperatures that you experience I would wait until late Spring/early Summer when the pond temperature will start to noticeably rise. At the same time, if possible, begin lowering the temperature in the aquarium with the goal of an eventual 3 degree Celsius difference (no more than 5 degrees). The larger the temperature differential between aquarium and pond, the higher the stress level the fish will experience. Too large of a differential may result in mortality.

Slick our koi lived indoors for 22 years of the 28 weve been keeping them slick the temperature of the 6 x 2 x 2.5 Aquarium was 22c constant even the water was pre mixed to that temperature .
In the summer we used a 300 watt Aqua One chiller on the tank to gradually reduce the temperature of the tank to that of the outside temperature of 15-16c, this was for show purposes .
After he show we then gradually raised again to 22c. Doing this this took weeks both ways .
If you want to put them outdoors go ahead and do it but bring the temperature down gradually its not going to hurt them then release when the temperatures are matched.
Six years on I'm glad to report all but one of those koi are still alive and thriving, sadly one of our two oldest koi Tiny passed away last year aged 27 our health officer who was formerly head of the BKKS HSC put this down to old age.
Meyer you have to understand we do not get temperatures in our ponds above 17c well in our pond we did see the 20-22c after we lost out parasol shading over the pond in a gale but that purely down to the fact that our back garden gets direct sunlight and last year was one of the hottest on record in the South West of the UK Slick lives up in the North East of the Country where the water temperature is probably cooler
We keep a very close eye on our water temperature and employ a remote pond thermometer to watch our water temperatures the air temperatures we follow with our weather station , watching temperature and barametric presures etc is hard wired into me it was part of our remit in the military aboard ship to do so , reporting the results to the MOD met guys and keeping records in the ships weather log .

Slick for greater accuracy in matching water temperatures its a god idea to invest in a hand held Infrared thermometer:-

http://www.digital-meters.com/tempe...mometers-c17?gclid=COKEi6Pi7sMCFQTJtAodnDgA-g

The model most of us Southwest koi keepers have is the TN1 Infrared thermometer and it is very accurate indeed , they cost £25.00 from the Tamar Veiw Aquatic Centre Carkeel nr Saltash Cornwall (we hold all our koi shows there) :-

http://www.tamaraquatics.co.uk/about-us.asp

If you want to match temperatures exactly why not buy a chiller unit as we did , they are a bit expensive though ours cost £300.00
You rig that to your filter running the return pipe through going back into tank but we never had any problems with our koi at shows through using one , its last ever job was to match the tank to the pond for the transfer when we shut down the 6 x 2 x 2.5 tank prior to selling it on .
Our angling mad friend Little Alex now has this chiller and uses it with an ehiem 2217 external filter to keep his bait fish alive which it does extremely well in his garage .

I don't own a cooler and because the aquarium temp is 22*c I have two small albino tropical cat fish in there keeping the bottom clean, so you can now see my situation, ps I only own one aquarium
