Re: growth rate of fry and water changes

["ALEX PASTOR" <alexp@idirect.com>]

Thank you for your $0.02.  The only reason the subject came up in the first
place is that some members of the list were trying to ensure that accurate
information was being provided for those people who may not have much or any
significant experience in raising fry.

According to the literature, and the experiences and opinions of most of the
contributors to the discussion, large, frequent water changes appear to be
the accepted norm.  However, there are a very few people who insist that
small, less frequent water changes suffice, despite the fact that their fry
seem to take a lot longer to mature.

I don't actually believe in all seriousness that the experiment requires to
be carried out.  But it is interesting to note, the majority of the
respondents who have written to express their view, believe that large water
changes are definitely the best way to go.  (Obtaining input from various
sources in this manner, is not unlike flushing grouse out of the
undergrowth.)

I would be quite happy to end the subject on this note.  Should someone feel
the need to carry out any comparison study then it is not too difficult.
Given the fact that one person is carrying out the various procedures
involved in caring for the fish, the variables and parameters of their work
should be a reasonable constant.  Obviously, most people on this mailing
list are not breeding their fish in laboratories.  Yet, if the results are
skewed dramatically in the direction of having much larger fry in a given
length of the time, then the experiment would not be totally meaningless.
At least the list archives would have the information should a newbie want
to know the best method by which fry can be raised.

Be happy and spawn!
