I know that I can keep goldfish in soft neutral salt-free
water with little concern, but is this changing with the breeding
techniques being followed (of using hot saline conditions to breed &
raise them).

I'm curious about the above breeding techniques; what temp is hot and
what
concentration is saline?

I work with a network of wholesalers, distributors and transhippers, so
you would think that this information would be readily available, but
it's not. Breeding and grow-out conditions are proprietary secrets.
Once, when I asked about temperature, I was told it varies, however when
I was combating a disease, one importer told me to put the Goldfish at
85F. When I questioned this, I was told that it would be no problem as
they are raised in that temperature (they grow faster and there are less
diseases). Another time, when I asked about salt, I was vaguely told
that whatever quantity I used would be fine (I got the feeling that
whatever concentration I used would not be as high as what that
particular buyer's breeder was already using). This is why I'm
researching to see what conditions are most beneficial to the fish
species (as opposed to the fish farmers).

The situation with livebearers, particularly Guppies has already gone too
far (imo). Many go sickly after a few weeks of being put into
freshwater. I only have one importer who occasionally has 'freshwater'
Guppies for sale. There should really be some type of a governing body
representing the industry (and hobbyists), to promote standards which
prevent the use of conditions which are short sighted. Local breeders
will need to pick up Guppy production, as is already done for Angelfish
and to an extent, Discus, but we cannot be expected to 'rescue' every
species the mass-producers mess up.

I'd better stop before I'm on a soapbox, and go back to gathering factual
data, ie:

http://www.fishbase.org/Summary/Spec...atus%20auratus
demersal; freshwater; pH range: 6.0 - 8.0; dH range: 5.0 - 19.0 ; depth
range - 10 m
climate: subtropical; 0 - 41°C (32-105°F); 53°N - 22°N
Inhabit rivers, lakes, ponds and ditches with stagnant or slow-flowing
water.... They live better in cold water.... Maximum recorded salinity is
17 ppt, but unable to withstand prolonged exposure above 15 ppt.

So how many ml per litre is 15 ppt (or US teaspoons per US gallon)?
