Semi-intensive culture of tilapia in Peru

Credit: Carlos Calderón Deza via: Wilder Rodriguez Arteaga (Peru)

In this production system, ponds of acreages from 0.5 to 3 acres are used with water exchange that ranges from 15 to 30% per day of the entire volume of the pond. In this system, aerators are used with aeration intensity that depends on the intensification level (ranges from 2-12 horse power/hectar).

The stocking densities used are highly variable and are in the range of 4 to 15 fish/m2 achieving fish production in the range of 20 to 50 tons/ ha/ year.

In this system is very important to monitor the levels of ammonia, pH, temperature and dissolved oxygen. In regard to fish feed, the extruded or pelleted feed is used with protein levels from 45 declining to 30% as fish grows.
