Abstract

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.
