Pale purplish-red, quickly degenerating when removed from the water and becoming distinctly orange; fronds bushy, with a cylindrical axis to1 mm wide and 200 mm long. Both phases readily reproduce vegetatively. Photographs by M.D. Guiry
AquaModel is a sophisticated, PC-based simulation program that provides data needed to evaluate the performance and ecological effects of proposed fish aquaculture farms. It is the first truly comprehensive model for net-pen aquaculture that simultaneously accounts for both water column and benthic effects. Interlinked submodels of fish physiology, hydrodynamics, water quality, solids dispersion, and assimilation were designed and preliminarily validated using field and laboratory data.
