A fundamental assessment in working with aquatic species is examination and evaluation of the life support system sustaining the animals. This is a critical step in the clinical examination of any aquatic species, not just fish. The emphasis of this chapter is on aquarium and aquaculture systems, but the principles may be applied to life-support designs for all aquatic organisms.
Water quality management is a basic component of successful maintenance of aquatic organisms. Information is presented on normal parameters, as well as on environmental diseases of fish.
