experience some killifish are more succepatable to inbreeding deformaties than
others. In Notho's I have raised several generations from one
pair. When I track back the line it woud appear that the N. GUN I have
been inbreeding for the past six or so generations have been inbread by the
someone else for many years before I got them. They remail
beautiful and overall unchanged.
recommend against culling minor deviants. Often genes are linked.
Such as sex and intellegence in humans. ; ) - ( Just kidding) By
eliminating one very minor defect you may also be eliminating a necessary and adaptive characteristic which
may not be aparent at first.
believe that fish which have long been isolated in ditches, pans or puddles,
such as Notho's are resistant to inbreeding. Fish which live in
larger ecosystems such as in contiguous drainage systems have the benefit of a
large genepool in nature. I believe that they suffer more when isolated.
It has been noted that when sequential collections were made at one site over
several years it appears that the Aphyosemions Geryi at that site show marked
changes over time. N. Biera's all pretty much look alike from
the photos I have seen from collections made from before WWII through
If two sibling killies were mated to
produce more off spring and those offspring were bred again. I think its
fair to expect some deformities. If the 3rd or 4th and subsequent
generations were culled to remove even the smallest deformities, after 10 or
more generations, will we have genetically prefect killies? Or will they
all be freaks?
