................... There
was a thread several weeks ago about incorporating location codes into
Apisto naming convention.  Here's another reason to implement such a
standard.  Known locations of a species may be genetically different
enough to warrant separation and to preserve the gene pool.




Sorry, Quite late on a lot of reply's here....schedule has been horrific =
and haven't gotten to check email, so I have resorted to lurking and =
just=20
reading the list replys.  There were a few threads I thought I might=20
add...

...on the locale issue it may become more critical for breeding some of=20
the more difficult apistos.  I believe it is mendezi that they now =
believe=20
there are subpopulations that won't interbreed based upon the river=20
system.  With closer analysis I think this is based on the horizontal
and/or vertical stripe pattern on their tail....which varies based upon=20
collection locale (river system).

On other notes...there is a scientist (?Dr Chao) that has started a whole =
collecting and education system with the native people.  The goal is=20
actually to help the natives make money utilizing their natural habitat...i=
e collecting fish rather than destroying it by logging or burning for=20
farmland.  Also, one of the goals of the program was teaching proper fish =
collecting and storage techniques so less of the collected fish die.  Some =
of the natives were also taught to record local collecting conditions.  =
Quite impressive goals and from the latest news I heard it was working.  =
The natives even had a holiday celebrating fish where the local kids even =
had a parade with fish costumes/posters/etc.

...on the sex ratio's.  Uwe is quite good about quoting how many species =
and the total fish raised.  From what I recall it was over 150,000 apisto
fry (I could easily be wrong though I am recalling this from an old=20
conversation).  Now how many were from which species, I cannot recall. =
There were also a few that were reversed, in terms of the number of males =
and females.  So don't assume that at low pH and you will always get ___ =
sex.  It depends on the fish.  I wish I had my copy of his article here =
with me, but afraid it is at home and I won't see that for another 48 =
hours.  Hopefully somewhere in the article it will say how many of what =
species, if not I will ask Uwe next time I talk to him...but that may be =
awhile.  Perhaps Julio will have some of that info.

Off for another sleepless night,  but apisto dreams
