Faculty and Staff - Timothy Bowden

Assistant Professor of Aquaculture
Address 237 Hitchner Hall
Telephone 207/ 581 2772



Dr. Bowden is the graduate coordinator for the Marine BioResources graduate program. This program allows students to focus on areas of pure and applied research that impact aquatic species that have resource value. This includes species from both freshwater and marine environments. This program has a special focus on aquaculture species and issues.

 Courses Taught

 SMS211 – Introduction to Aquaculture.

An introduction to aquaculture is an overview of an extensive and developing area. The course looks at; what is aquaculture, why is it important, its history, the methods involved, where in the world it is carried out, the species involved, products, business issues, regulatory issues such as siting and lisensing, marketing and packaging. The course is intended to give the student a broad understand of the basic issues associated with aquaculture, preparing them for a more in depth study should they decide to continue to a concentration or minor in aquaculture that is available to any student on campus.

SMS 401 – Critical Issues in Aquaculture

This course is a tutorial course that offers a rolling program of different topics that are important within aquaculture. The course offers the chance for students to study the literature in depth, discussing particular issues associated with topics while developing their presentation skills and learning how to source information through online sources such as scientific databases. Students are actively encouraged to participate with oral and written presentations and in depth discussions. Recent subjects have included; environmental impacts on aquaculture, bacterial and viral pathogens and vaccinology

SMS422 – Biology of Fishes

Dr Bowden teaches the immunology section of this course. He covers an overview of the basic principles of vertebrate immunology with a very mammalian bias, as this is the focus of most of the information. He then matches this basic concept to our current understanding of the fish immune system, highlighting the similarities and the differences.


Dr. Bowden’s previous research areas included; vaccine development of fish using bacteria and viruses, development of challenge models in aquatic species, immunological studies of species new to aquaculture such as; halibut, cod, haddock and sharp-snout seabream, studies on alternative techniques for measuring toxicity of aquatic xenobiotics, epidemiology of viral pathogens, development of management strategies for aquaculture. He has have worked on aquaculture in the UK, Spain, Norway and USA.

Dr. Bowden’s current research interests cover a number of areas;

Future research should use the emerging technologies such as next-generation sequencing and transcriptomics to help understand how animals react or respond to changes around them, whether those are environmental or pathogen induced.

 Student Involvement

I have considerable numbers of students involved in my research both undergraduate and graduate. From basic aquarium support to complete projects based in lab and aquaria. I have volunteers, interns, independent study students and capstones. Aquarium technicians look after my research animals on a day-to-day basis, grow live feeds (algae, rotifers and artemia) for a wide range of research species, develop production systems (seahorses – yes we had babies, and razor clams), manage large research trials (I had two junior year students manage a vaccine trial in salmon smolts). If you are interested come and talk to me, meet my current students, read my web page find out what past and current students thought of working in the Bowden lab.

I have a number of outreach programs. We have developed teacher workshops on aquaponics, placed educational aquaria in schools to help raise awareness of aquaculture, we host several 4H and similar K-12 student groups on campus. I am happy to have students present/attend at local town meetings, special interest groups and conferences
