Dr. Bayer has been involved in lobster research for nearly 30 years and since 1995 has been Executive Director of the Lobster Institute, located on the campus of the University of Maine. His primary interests are in the areas of lobster nutrition, management and pathology.
In addition to his work with the Lobster Institute, Dr. Bayer is a Professor of Animal & Veterinary Sciences at the University of Maine. He also serves as an adjunct professor in Food Sciences and in 1979 was a visiting scientist at the Institute of Marine Biochemistry in Aberdeen, Scotland. He has taught a variety of courses, such as: Endocrinology, Nutrition, Anatomy and Physiology, Marine Resources, and Aquaculture.
Dr. Bayer has written or collaborated on dozens of articles for a variety of professional journals, and is the co-author of several books and industry manuals.
He is also the co-holder of two U.S. patents – one for the gaffkemia vaccine and the other for a method and solution for improving frozen seafood quality. He is also known for his work with shell disease research, testing of artificial diets and baits for lobsters, developing tests for determining illegal removal of lobster eggs with chlorine bleach, and a variety of other research related to lobsters and the lobster industry.

Dr Bayer has worked with many graduate and senior students on various projects, here is a sampling of studies with University of Maine students which were conducted as part of my MAFES project’s look at lobster health:
- The Masters thesis of former Animal & Veterinary Sciences (AVS) graduate student Julie Kaye, funded as part of this project, and presented at the 8th International conference and workshop on lobster biology and management, looked at the incidence of shell disease in Maine and a possible association with copper and/or mercury.
- Working with the sensor lab in the Department of Electrical Engineering, jointly with Food Science & Human Nutrition graduate student (now doctoral candidate) Jason Bolton, a sensor is being developed to determine lobster quality and vigor based on a serum protein measurement. This project was funded by SBIR.
- Work we conducted prior to this project indicated that the bacteria Photobacterium indicum could be associated with mortalities in lobster pounds . P. indicum is an opportunist that seems to have developed into a pathogen. Marine Bio-Resources graduate student David Basti, DVM based his thesis work on looking at patterns of mortality in lobster pounds. A stocking experiment was designed to monitor mortality in lobsters during a normal impoundment cycle. 483 lobsters were sampled for bacteremia.
- In a concurrent study, lobsters were treated with a minimal dose of 2 mg of oxytetracycline by gavage or feed in an attempt to decrease mortality in pounded lobsters This study was done by AVS student Sarah Spurr along with lobstermen Herb Hodgkins of Hancock, Maine and Jason Joyce of Swans Island, Maine. Lobsters were donated by Trenton Bridge Lobster Company in Trenton, Maine. A follow up study was conducted by feeding lobsters as they were being placed for tidal pound storage.
- A study of the affects of ocean acidification on juvenile lobsters with graduate student in Animal and Veterinary Sciences, Joshua Hall.
- Current-day use of high speed pot haulers had been suggested by some lobstermen as a stress producer that may allow movement of P. indicum bacteria, normally found in the gut of the lobster, to the hemolymph. I worked at that time with now post-doc David Basti, DVM. As part of a capstone project, AVS undergraduate Matt Louis, made video observation of the stress on lobsters hauled at high speeds.
- Many more senior capstone projects were also undertaken.
