yes but somewhere some time someone makes these laws up and a whole group of them go "yay thats a good idea"

and then theres the whole pile of people that deal with the law everyday and DONT say"hrmmm thats a bit screwy, lets fix that"

plus in NZ , even if theres a major problem and he people get up in arms about something, Very rarely does anything happen about it even with media coverage. Democracy doesn't seem to work here

There are usually lots of people who do, but few that have the authority to actually do anything.

NZ isn't a true democracy, never has been. It's at best a representative democracy. People don't vote on most issues, you just vote on who you want to have all the power and once they're in you have little say.

What people don't seem to understand is that the politicians make the laws--full stop. The beaurocrats are told to inforce it with nothing added to the budget and no extra staff. If they think the law is stupid they cannot change it and if they don't inforce it they are legally liable. A good example is the fencing of swimming pools act where you have to fence a cheap pool from the wharehouse and the fence costs 10 to 20 times what the pool costs and you live next to a river which is unfenced, or you live in the country and your kids walk a mile or so home and play in the water race all the way. Anyone want to explain that to the pool owner? Also you bought the pool because both the river and the water race are not fit to swim in because of runoff from farms.

I heard you can stimulate the morphing by feeding live tadpoles which have high concentrations of the hormones required, any truth in this???

Hi Fishguy, September 2012 I moved to the South Island, Central Otago. For 11 months now I am feeding two of my Axolotl with lots of tadpoles found everywhere down here. There is no sign at all that they even think to morph. They are well nourished and they lay eggs every three months. I've read that 'rumor' in the German Axolotl forum that they will immediately morph if fed with tadpoles. maybe it's more the law in Europe as you are not allowed to take tadpoles home as all these animals are protected under very strict laws.

They come from Mexico where there are low levals of iodine in the environment (like NZ). Iodine is required to produce thyroxin which is the hormone required to stimulate metamorphosis. Feeding iodine or sheep thyroid gland is the usual way to get them to morph. They have evolved to reproduce in the juvenile state and have no need to morph and usually die an early and nasty death if artifically encouraged to---so not advised for that reason. Upsetting MPI can end up with you getting free board and lodgings at her majesty's pleasure and massive fines. Not to mention the entertainment you may provide for other inmates.

Feeding them iodine should be pretty trivial.

Came in many years ago when the awareness of the fragility of our native species wasnt in the minds of the powers that be

At points in the past not only did the powers of be not have an awareness of the fragility of native species they thought it was a GOOD idea to introduce as many exotic species as possible. Didn't think europeans could survive without lots of familiar animals...

I have kept axolotls for over 2 decades and have accumulated much information about them.Axolotls in captivity have only distant genetic similarities to wild idividuals.Individuals imported to france in 1864 where distributed along with their offspring throughout france and then europe and subsequently the world. mutations such as we see today are unknown in wild populations .luecistic was the first mutation recorded early in France. Albino is a result of a tiger salamander cross. an albino tiger salamander was found and introduced into the gene pool.Therefore the nz population has an american connection, perhaps via Britain. Thus the nz axolotl population isn't really the same as the almost extinct population found in lake xochimilco. Additionally metamorphosis in wild individuals is almost unheard of, being much more talked about in captive populations. There are numerous reasons for this not just to do with those out lined above and not just to do with iodine.

All albino axolotls are a result of tiger salamander crosses,( an albino tiger salamander). Very early reports of albino axolotls refer to luecistic individuals. Which are the first mutation recorded from the original specmens taken from mexico to France in 1864. Albino doesn't occur in axolotl wild populations at all.

wild populations aside.

is it not possible for non tiger salamander axolotls to sporadically produce an albino ...

If they have albino in their genetic line they can(which off course stems from the distant cross).albino axolotls are white , golden or can be a very rare copper colour.There are also many other genetic variants that appear to be albino but are not true albino.For example a albino/xanthic cross!Also axo's can change colour with different light conditions and an increase of riboflavin in their diet and gut loading their food before it is consumed.

and here is me who has learned that an 'albino' is a genetic defect and has nothing to do with the genetic line.

a albino axolotl will have red or pink eyes and no other coloration on the body, no gold, no black or copper. white axolotl with black eyes and gold, black or any other color are not albinos they are leucistics.

Albino is a recessive gene for lack of melanin and melanin comes from the greek word for black. With two genes it can be gold (still lack of black) and a red eye because of lack of melanin in the eye. Leucistic is for lack of colour and can be complete or partial. You can have a black bird with some white feathers or all white feathers and you can have a white/gold frog with some green patches but they will have a black eye.

It can be very complicated as those trying to breed albino frogs have discovered

I have bred albino/albino kribensis and always had a few normals in the fry which you would not expect.
