Research Interests

The focus of our research is on the physiology/endocrinology of fish larval growth, development and health, with a view to developing hatchery technology to promote larval rearing in aquaculture. In particular we are studying the physiological deficiencies in the digestive, osmoregulatory, immune and endocrine systems of marine fish larvae during the course of their early development, and how these deficiencies are compensated by inputs from the mother fish, food and the environment. The maturation of organs/systems during late larval development/metamorphosis and its control mechanisms are also of particular interest.
