Background
What does anadromous mean?
Fish that divide their lives between fresh and salt water habitats.
Which type of predator eats salmon while they are living in the ocean?
Orcas and seals
When coming back to their natal streams to reproduce, what are some problems that salmon might run into?
dams, fishermen, water that’s too warm, not enough water in the stream, pollution
What happens to salmon when creek water gets too warm?
The salmon are more likely to get diseases or parasites when creek water is too warm.
What watershed do we live in?
Coyote Creek or Guadalupe River watersheds
What is a watershed?
An area of land that drains off into a body of water such as a lake or the ocean.
Do anadromous fish live in fresh, salt water, or both?
Both.
What is a dam?
Dams restrict water flow.
What is the difference between climate change and weather?
Climate change: Long periods of change in average weather patterns over large regions
Weather: Short period of change in local atmospheric conditions over minutes, hours, or days
Name a way that restoration is done on Coyote Creek.
remove invasive plants, plant native plants, clean up trash, reduce pollution
An ecosystem is a community of plants, animals, other living organisms, and non-living things that work together.
What does it mean when an anadromous fish goes through smolitfication?
A complex series of physical changes that happen to young salmon that helps it adapt to living in fresh water to sea water.
How do dams harm anadromous fish?
block passage/movement, trapping branches and rocks that salmon use to make nests or hide it, changing water temperature or chemistry
What is conservation?
Act of protecting habitats.
Name a way that conservation is done on Coyote Creek.
Valley Water builds fish ladders and releases water from dams to keep creek water cool enough.
What is a keystone species?
A keystone species is an organism that holds an ecosystem in balance.
What type of land predator do salmon face when they swim back up their natural stream?
Bears.
What are some threats to anadromous fish?
Dams, climate change, habitat loss, pollution
What is restoration?
Ecological restoration is the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed.
Where does Coyote Creek flow out to?
San Francisco Bay
Why is a keystone species important?
Keystone species play an important role in their ecosystems that keeps the habitat and other species healthy.
Why are estuaries important?
Estuaries form where a river meets the ocean. In an estuary, there is a mixture of fresh and salt water allowing the anadromous fish to slowly adjust to salt water before entering the ocean.
