Ichthyology
Each NRTG course includes free, lifetime admission. Enrol once – come back anytime.
Description
The two-day, fully online Ichthyology course provides a comprehensive overview of marine and freshwater fish phylogeny, ecology, and physiology. Participants will develop the foundation for studying and managing fisheries and evaluating biological requirements for fish habitat restoration projects.
Taught by one of Canada’s foremost Ecologists and researchers, this ‘hands on’ online ecology course training includes presentation, lecture, and case study reviews.

This course is approved for 10 Continuing Education Credits (CECs) under the Society for Ecological Restoration’s (SER) Certified Ecological Restoration Practitioner (CERP) Program. Participants are responsible for uploading their certificates at ser.submittable.com to receive CECs.
Program Outcomes
Upon successful completion of this program, you will be able to:
- Identify, compare, and contrast major taxonomic groups of marine and freshwater fish using standard phylogenetic classifications.
- Identify key internal and external anatomical features of fish and explain their primary functions.
- Describe core physiological processes in fish, including respiration, circulation, digestion, and reproduction.
- Describe major ecological behaviours and guilds of fish, including feeding strategies, habitat use, and life history patterns.
- Apply principles of fish ecology and physiology to interpret case studies related to fish habitat restoration, fisheries research, or fisheries management.
Certification
To successfully complete the Ichthyology course, participants must attend at least 50% of the scheduled time and actively participate in class discussions.
Prerequisites
There are no prerequisites for this course, although a background in biology would be beneficial.

Instructor Profile
Jeff Sereda, PhD.
Manager, Ecological and Habitat Assessment, Owner Sereda Environmental

Jeff holds a PhD. in Limnology and an Aquaculture Technician Diploma. He served as manager of a commercial salmonid hatchery for 4 years, lectured at the University of Saskatchewan on topics of fish physiology, taxonomy, ecology, conservation, and aquaculture. Currently, Jeff is a Manager of Ecological and Habitat Assessment, and formally an Adjunct Professor at the University of Saskatchewan.
Jeff’s research has encompassed topics such as assessing the risk of aquatic ecosystems to anthropogenic eutrophication, macrophyte management, fish habitat restoration, and the impacts of water management on species as risk (Bigmouth Buffalo, Chestnut Lamprey, Plains Sucker, and Lake Sturgeon). Jeff’s research has been presented at over 60 national and international conferences and resulted in 20 peer reviewed publications.
