Aquaculture is an activity aimed at producing and fattening organisms under controlled
conditions of species developed in the aquatic environment, with biofloc technology being
a viable alternative, taking advantage of organic and inorganic waste through heterotrophic
microorganisms present in the water and making better use of water resources. The
objective of this study was to evaluate the production of red tilapia (Oreochromis sp)
reared in a biofloc technology (TBF) system, using a descriptive non-experimental design
employing a total of 5000 fingerlings with an average initial size of 1.5 cm and weight of
0.6 g, constantly monitoring physicochemical parameters (pH, ammonium, nitrite, nitrate,
sedimentation, dissolved oxygen, and temperature). Aspects such as weight gain (WG),
Total feed intake (TF), Daily intake (DA), Feed conversion factor (FCR) were measured. The
results showed that the physicochemical parameters of the water in this system are within
the recommended ranges for tilapia culture. It was observed that in some weeks during
the growth of the fish there was a low feed conversion ratio with values of 0.33, 0.35, 0.53,
0.67, 0.79, 0.91, 0.99, thus influencing the reduction of production costs, taking into account
that the closer the FCA is to zero the greater the efficiency of feed use, so in this case the
implementation of the system was not optimal (by volume of production) because there was
not a low index throughout the growing season, generating profitability problems.
