For almost every biological system studied to date, basic physiological principles differ fundamentally across the life stages of fishes. Form and function of embryonic (unhatched) and larval (post-hatch) fish place numerous constraints on physiological systems, such that basic principles derived from studies on adults cannot be easily applied to understand early life physiology. For example, among many other physiological features that differ from adult stages, early life stages of fish lack a functional gill and utilize cutaneous surfaces for physiological exchanges, do not require an oxygen carrying molecule to meet metabolic demands, and obtain nutrients endogenously from yolk stores. Therefore, there is an important need to understand how these physiological systems of embryonic and larval fishes respond to changes in the environment and whether environmental changes influence the developmental trajectory of these systems (plasticity).
Our symposium includes speakers working in several different areas focusing specifically on early life and development. We feel that this symposium will provide an opportunity to discover potential parallels in the development of physiological systems in fishes and to synthesize the challenges that lie ahead for fish developing in rapidly changing environments.
