[Killietalk] Tetani was hybrid vigour and still is

["lee Van Hyfte" <littleleeper23 at hotmail_com>]

Hi Bob et all,

 It is very interesting the reaction between HUFFA vs light induced 
"seizure".   John Hopkins university recently posted results of a research 
project where the were able to reduce the incidence of seizure activity in 
humans with diets high in fats (and presumably fatty acids).

Gee can you imagine it took us this long to figure this out considering the 
the myelin sheath is made of FAT!!!  A great insulator against electric 
current = no "short circuiting"  HmmmH!

HUFFA More-  A friend has reported much greater vigor and growth in his 
Cameronense group fry using huffa rich feed.  Far beyond BBS alone.  Results 
are showing earlier sexual maturity and fewer runts!  Which Cameronense 
group fish like to do any way.  Develop a larger dominant male that is.

HUFFA EVEN More-  Verility in some species (human) has a direct correlation 
to Fatty diets.  Males with higher fat intake were less veril while females 
with to low of fat in the diet resulted in low fertility low drive,  
excessive fat intake in either case resulted in "you know the rest"   The 
point is that I wonder if this is practical in fish nutrition a good robust 
female produces well.  Fat males like to get fatter?  Just FOOD for thought. 
 Any ideas?

Hybrid Vigour-  Now here is the real question?  Aren't we assuming a bit to 
much to imagine that we can maintain a single "localtiy/population"  
indefinately considering the number of specimens typically introduced.  
Deadly genes will weed themselves out most certainly if the animals do not 
succome to their natural genetic fate.  Population dynamics are truly beyond 
my scope.  But I do know enough to realize that inbred lines can and often 
do fail.

    How many times have their been successful transplantation or 
reimplantation of extinct or endangered killiefish.  N. rachovii Black  pups 
any others?  The fact is we alter the genetic diversity with inbreeding.  We 
charitably select the prettiest/biggest ones for brood stock.  After we get 
done with them they can no longer survive in their native habitat.  You know 
that little fry that died unexpectedly well that was maybe the one which was 
going to adapt to the new natural conditions.  Inbreeding develops a less 
adaptable gene pool like it or not.

I have heard of 30+ generations of austrol. nigripinnis from a single pair.  
Their natural habitat requires this of them same with the pups.  But what 
about the stream dwellers one flood and there is a new gene pool for good 
and for bad..

Has anyone seen the typical xiphidius Crique Boulanger floating around? Not 
nearly as nice as they used to be, now are they? Now a friend developed an 
"aquarium strain" that was 10 times as productive and prettier than either 
of its counterparts (cb x PK15)  What does this say?  both strains will be 
lost to the hobby I guarantee it.  but how about an "AS" that is easier to 
breed prettier and a lot easier to remeber the name of.  (don't think that 
is not a big part either)  If the color and fecundity have dropped so badly 
in Crique Boulanger could we not argue that it is allready an "aquarium 
Strain"!!!!!!  Grossly altered from it's orginal genetic lines, a mere 
representation of the species.

I am not saying hybrids are good by any means speciation has occured for a 
good reason.  Intraspecific outbreeding may eventually be a must.  The 
rainforests are going away like it or not.  And I really don't forsee the 
amazon river drainage becoming a nature preserve nor all of africas west 
coast.

If you have a good idea of what to do the whole world would like to hear it. 
 My sons will likely see the extinction of half the worlds killiefish let 
alone anything else that falls in man's way!!

OK MY SERMON IS OVER I am sure that i am going to get reemed.  Just food for 
thought.

God Bless,  Lee "the Rivnut" Van Hyfte <><
