A Stage-Structured Fishery Model for African Catfish and Nile Tilapia Feeding on Two Food Resources with Harvesting

Table 6

Simulation results using optimal harvest rates found in MATLAB, using patternSearch. The columns present the maximum sustainable biomass yield (grams per litre and day) and maximum sustainable financial profit (USD per litre and day). The rows indicate the fish stock scenarios.

	Maximum biomass yield	Maximum financial profit
Only Nile tilapia	0.0024	0.0074
Only African catfish	0.0014	0.0057
Both species	0.0027	0.0081
