Where do science, industry, and reef aquariums meet?

The reef aquarium hobby, on the surface, covers a discipline mainly focused around the biology of creatures found in the vicinity of tropical coral reefs. It involves establishing model ecosystems in closed recirculating aquariums, so it offers insights into ecological processes too. The hobby also involves a fair amount of chemistry, and the maintenance of theses systems can provide endless fodder for marine chemists wishing to study chemical processes. Students of engineering may find a reef aquarium niche in the study of water flow regimes, pumping systems, filtration methods, control devices, lighting, temperature control, automation, aquarium suitable materials, architectural design, among other options. While we aquarium hobbyists know and appreciate these things, there are still many unexplored areas that are ripe for research involving our aquarium systems or the living things housed within them. This lecture is an overview of some fascinating mysteries that can be studied using reef aquariums in the academic setting. The benefits of these studies are far-reaching, not just for the aquarium hobby.

Giant Clams: Their Identification and Evolution, and husbandry of Giant Clams in aquariums

Giant clams are popular reef aquarium inhabitants with beautiful mantles that harbor photosynthetic symbiotic zooxanthellae. Their identification is not always easy as the relatively low number of species are closely related and may have overlapping features, aside from the existence of hybrids. Some new species have been described recently, and there is more to discover about them and the evolution of this group. Recent fossil discoveries shed new light on their evolution as well. Giant clam husbandry involves some key points with respect to lighting, water quality, feeding, predators, parasites, disease, and potential growth versus aquarium size..
