First, look at how the algae is structured in the water. Most common types fall into these three categories:
Color provides a major clue about the pigments the algae uses for photosynthesis: Easy identification of freshwater algae
: Likely Blue-Green Algae ( Cyanobacteria ). They contain phycocyanin. Note: Some like Nostoc form firm, jelly-like "freshwater grapes" attached to rocks. First, look at how the algae is structured in the water
: Fresh blooms often smell like freshly mowed grass; older, decaying blooms may smell like rotting garbage. Note: Some like Nostoc form firm, jelly-like "freshwater
Identifying freshwater algae is easiest when you focus on three main factors: (growth habit), coloration , and notable textures or smells . 1. Identify the Growth Habit
If you are observing algae in person, these simple characteristics can narrow it down:
: If you can pick up the algae with a stick and it hangs like hair, it is likely a filamentous green alga. If it is slimy and slips off immediately, it may be cyanobacteria .
