Fish Overview

This series of five lessons introduces students to the number and variety of Great Lakes fish. Students use a simple key, based on distinguishing characteristics, to identify several common fish families. Lessons then explain the importance of healthy fish habitat, illustrate the significant stages in a fish’s life cycle, and describe techniques for tracking and monitoring Great Lakes fish populations. The final lesson highlights a variety of people who have chosen scientific careers studying or teaching about the oceans and Great Lakes.

Lesson 1: Fins, Tails and Scales: Identifying Great Lakes Fishes
Introduces students to distinguishing characteristics of Great Lakes fish. Part II: Leads students through the process of using a dichotomous key to organize and identify 10 common fish families.
