Thank you,
Some very interesting reading there. I note that whilst there is some evidence to suggest that Intergrades are affected - the main evidence around it was blurred slightly by the use of synthetic pyrethrins which Jamie pointed out *may* be accountable for the symptoms seen and not be DPS. Not saying it does not affect Intergrades, only that in the stated case it was possible it may not have been DPS. The main points I got out of it were:
* There is some evidence to suggest that it may be in the best interests to treat Intergrades as though they are Diamonds
* Removing night heat for Diamonds is strongly recommended (even for hatchies/juvies)
* Max temps when heat is applied should not exceed 30c and only be for a few hours a day (mostly mornings seem best)
* A Diamond will not necessarily act in its own best interest and seek a cooler hiding location if a warmer one is available (hence keeping max temps lower)
* Always have an area of the enclosure at ambient temps
* Given that I live in Intergrade heartland - ambient temps most of the time with a couple of hours warmth (not exceeding 30c) should be all my Intergrade should need.
Thanks Skeptic - some great info here.
As a sidenote I recall reading an article (I think it was Doc Rock but cannot recall - it was a larger scale breeder) who recommended a similar regime for getting the best out of Murray Darlings. It was along the lines of around 30c for a few hours a day and minimal to no heating otherwise. As I recall there was no mention of DPS, but I think they were better breeders and generally overall healthier when kept like this. A similar statement was also made about Bredli.
Maybe we are becoming too accustomed to all the tropical northern species and morphs etc and forgetting about the husbandry of the inland and cooler climate species?
Certainly has given me some food for thought....has been a productive exercise.
