Feed has a strong positive influence on growth, but due to its high
price, a significant negative influence on profits in comparison with
other inputs. Feed conversion ratio averaged 2.1, a fairly high value that
probably indicates overfeeding in many ponds. When integrating
species of lower market value for nutrient recovery purposes, it is
especially important tofind the balance where feed inputs are reduced,
integrated species provide adequate nutrient uptake before water
release to the surrounding environment, and the system remains
competitively profitable. Therefore, determining the optimal ratio of
density of organisms or crops and the area on the farm utilized for each is
a high priority in future research of best practices (Yuan et al., 2004).
