Tilapia feed market of Costa Rica.
The source and the
manufacturing process of tilapia feed sold in the country and
registered in the Quality Control Program for Animal Feed of
the Ministry of Agriculture and Livestock of Costa Rica and
the prescriptions according to the physiological stage, chemical
compositions and the relations crude protein : metabolizable
energy and calcium : phosphorus, were evaluated and
compared to nutritional requirements. The physical quality
was evaluated in terms of particle size of the pellets against
the size of fish. The market study compared the selling price
per nutrient unit in each formula, with respect to its contents.
It was determined that 82.35% of the formulas were manufactured
in Costa Rica, 82.23% were extruded feed and 41%
of the formulas are recommended for all types of tilapia fish,
which resulted in inconsistencies with respect to the requirements.
However, all crude protein levels in different fingerlings
formulas complied with requirements. With respect to
physical quality the situation is more critical, since only
23.53% of the registers indicated the size of the pellet. Only
5 out of the 17 registered formulas are being marketed, reason
enough to conclude that comparing formulas on their selling
price per nutrient unit, is not a good criteria for selecting
a particular formula.
