Physiology and propagation of corals and reef fish
have recently changed the focus of my research from cardiovascular and respiratory development of fish and amphibians to coral and coral reef fish propagation and physiology. I am mostly working on aquaculture of tropical ornamentals, in part for conservation reasons and in part because tropical reef fish breed multiple times in a year, and are much smaller than such marine aquaculture subjects as cod, haddock, or flounder, thus are much easier to experiment with.
Coral reefs, and the fish and invertebrates cohabiting them, are under increasing pressure from human exploitation and environmental damage worldwide. One pressure is collection of corals and fish for marine aquaria. Almost all marine aquarium organisms are currently wild-caught; only about 5% are tank raised. Many highly desirable species, for example dwarf angel fish, have not yet been raised in captivity. Many corals, although possible to raise in tanks, still come from the wild because coral farming is very expensive. I am testing new ways to grow corals in aquaria to make coral farming more economically viable, and I am trying to develop ways to spawn and raise larval dwarf angel (Centryopyge) species and scarlet cleaner shrimp (Lysmata amboinensis) among others.My long term research ambitions for coral physiology are to investigate the impacts of anthropogenic disturbances - increased CO2, increased nutrients, increased temperature, increased UV light exposure, and decreased calcium carbonate saturation, for example - on growth and health of corals.
