A species consists of individuals that share the same gene pool.The Great Lakes region is home to an impressive variety of fish, numbering more than 160 separate species. Use a dichotomous key to identify 10 Great Lakes fish families.Organize Great Lakes fish (cards) based on similarities and differences.Describe how these characteristics help fish survive in their environment.Name several distinguishing characteristics of Great Lakes fish.Describe the physical characteristics (traits) of fish that help them survive in their environment.Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.įor alignment, see: Fish ID NGSS Summary Lesson Objectives MS-LS4.6 Biological Evolution: Unity and Diversity.Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment.

MS-LS4.4 Biological Evolution: Unity and Diversity.By observing and comparing these features, students learn that fish, like other living organisms, can be organized and classified into meaningful groups for identification and further study. These characteristics help fish survive in their environment.

Please note: A full refund is issued if a course is cancelled.Each family of fishes in the Great Lakes region has physical traits that set it apart from others, called distinguishing characteristics. Non-Refundable Fees: Some courses may have non-refundable tuition, application, and/or lab fees. RegistrationĬourse fees are refundable if you withdraw a minimum of 10 days prior to the start date of the course.Note that special refund deadlines are stated for some courses, and we are unable to issue refunds after those deadlines - information will appear in the intake's details available on the NREP schedule page.

Participants are responsible for their own classroom supplies (pen or pencil and paper), and should be dressed appropriately for a laboratory-based training session. Ideally, participants are working in or have experience in the fisheries field. No formal prerequisites exist for this course. Class vs FieldĬlass: 1.0 or 2.0 days Field: no field session(s) Prerequisites This lecture and "hands-on" course focuses on using preserved and live specimens to give participants an opportunity to practice their identification skills. Please contact us for further information. **Note: Course content will vary by province or state of delivery. Note: The one-day course contains less review of non-salmonid species. Other topics reviewed include: classification, voucher sampling, identification key design and use, threatened/endangered species, and life history and distribution information. Using identification keys, participants will complete practical identification exercises to key fish to both species and family level. This one or two-day, laboratory-based course is a very practical introduction to the identification of both salmonid and non-salmonid freshwater fish species common to a given province*.
