Floating capacity for fish
meals is determined by the chemical and physical characteristics
of the raw materials, industrial process and handling post
manufacture. With such diversity of factors, it becomes necessary
to determine at least, the physical quality of the feed,
in order to verify if the amount of feed is adequate to the
fish.s biomass requirements in each pond. Based on this, this
experiment was proposed to determine if the measuring methodology
had repeatability. Based on the results it was concluded
that the process is effective if at least two formulas are
evaluated and that it is convenient to set a five minutes observation
period to evaluate floating capacity of the pellets. It is
recommended to continue conducting studies to evaluate the
physical quality of more rations and sources and specially, try
the evaluations in different water volumes in containers of
varying diameter.
