Research Interests

Parasitology and Diseases

My research areas involving parasites and diseases are numerous and constitute my primary field of responsibility. They include taxonomy, systematics, development and life histories, diagnoses and management of diseases, ecology, pathogenesis and host-parasite relationships, and public health. I am involved with a wide array of agents including viruses, bacteria, fungi, and numerous protozoan and metazoan groups. My present taxonomic and systematic studies emphasize digeneans, nematodes, myxosporans, coccidians, microsporans, and haplosporans. For other types of studies, I am involved with all parasitic groups; most of my academic and service obligations also involve all the above general areas of interest.

Aquaculture and Fisheries Science

Aquaculture and fisheries science involvement includes both applied and basic areas. My interests in aquaculture concern viral and other diseases of penaeid shrimps; other crustaceans such as crayfishes and blue crabs; and finfishes, including local and other species such as the red snapper, mullets, and small fish models. Whereas most of my research involves parasites and diseases, my interests also include biology of the animals and culture techniques. Directly or indirectly, I utilize that information or various contacts for service and educational obligations. My interests in other areas of fisheries include the biology of fishes (both finfishes and shellfishes), with an emphasis on local species collected on a routine basis. Most of my research has involved migration, health, reproduction, rearing, diets, and associations and interactions with other fishes, crustaceans, molluscs, and sometimes their symbionts.

Environmental Biology and Neoplasms

My interests in environmental biology and neoplasms involve both field and laboratory studies. Initially those studies not involving a parasite were restricted to descriptive aspects of affected animals in the local environment. Whereas much of my work has involved infectious agents, some has involved the influence of natural or manmade conditions or agents on aquatic animals. Since 1975, I have been conducting experimental studies to determine the effect of carcinogens or other toxicants on fishes and shrimps. My involvement has included rearing and maintaining healthy animals as well as designing experiments and assessing the effects of toxicants or perturbations. For my toxicology input, mostly I am involved with better defining small fish models. For my parasitological input, I am establishing various host-parasite associations in "model" fishes as indicators of environmental health. This aspect of my work also involves field and laboratory studies and treats the effects of both biotic and abiotic factors on the parasite associations.
