A Simulation Model of Recirculating Aquaculture SystemGrowing Ornamental Fish

摘要

Reasons for research. Ornamental fish production in recirculating aquaculture systems (RASs) is an important sector of Israeli aquaculture. Ornamental fish exports from Israel doubled between 1999 and 2004 (FAO, 2005). Worldwide, ornamental fish exports are worth US$ 278 million annually, and the wholesale trade is worth around US$ 1 billion per year (FAO, 2005). However, although RASs offer a high degree of fish environmental control and allow year-round production, their operation requires intensive management of the many unit processes involved (Summerfelt, 1996; Libey and Timmons, 1998).
