Professor Fuiman's research has spanned a variety of topics within marine biology, all relating to the behavioral and physiological ecology of marine vertebrate animals. As Director of the University of Texas Marine Science Institute’s Fisheries and Mariculture Laboratory, he is actively engaged in aquaculture projects. These include (1) development of culture methods for southern flounder to facilitate stock enhancement programs of the Texas Parks and Wildlife Department; and (2) development of more efficient and environmentally sustainable protocols for managing broodstock fish. Other projects are at the interface of basic fish biology, fish physiology, and ecology. These include (3) dynamics of transfer of fatty acids from adult diet to eggs; (4) relationship between egg composition and larval performance in fishes; and (5) interpreting food-web dynamics from biochemical tracers in eggs.
