The aim of this chapter is to address these two problems. (a) To develop fish-farm simulation optimization equations and an application method, (b) to demonstrate the application of these equations in real life situations: 2,500 ton/year marine netcages and 1,000 ton/year recirculating aquaculture systems.

The results. The model optimizes: (1) facility allocation, i.e., number and volume of netcages in each growing phase; (2) fish-batch arrival frequency; (3) number of fingerlings in a batch; (4) number of days in each culture netcage, and (5) grading criteria along the production lines. Compared with today existing management the optimized layout was superior, giving 1,687 vs. 981 ton/year).

It is recommended that every aquaculture enterprise apply this concept in its design stage.
