Re: factors relating to growth

[Allen Wood <wood@uscolo.edu>]

Doubling length, doubling width and doubling depth of the body increases
body volume (and body mass) by a factor of eight (2x2x2=8) with a tremendous
increase in food requirement.   Also, the growth curve would probably be
steeper for a 1/2" fry compared to a 1/4" fry. This means that the 'natural'
growth rate would be higher for 1/2" fry with a resulting increase in
nutritional needs.  I certainly have underestimated the food requirements of
many species as the fry grow.
