Objective this week: To understand major morphological differences between individual fish classes through lecture, quizzes, and lab work.
Monday
Bony fish overview and review major anatomical features of fish.
Watch these two videos:
Next, answer these questions over the hatchery documentary. These questions are due by WEDNESDAY at 4pm either through E Mail or on paper:
1. What are three factors that make it difficult for fish to live/spawn in streams? (+3)
