  • 20mm across carapace - juvenile
coho salmon oncorhynchus kisutch
Coho salmon – Oncorhynchus kisutch
  • 35mm fork length – parr
  • 50mm fork length – smolt

predator prey cards
Predator/prey cards
  • The Striped Bass represents a non-native fish.
  • These fish appear on the predator/prey cards.
  • Predator/prey cards describe a situation with consequences for crabs and salmon in the estuary depending on factors such as your size and location.
estuary condition cards
Estuary condition cards
  • Estuary condition cards describe the tides and different factors that will impact life in the estuary.
  • The habitats below the low tide line include only the open water channel and the eelgrass meadows.
  • If you’re crab or salmon occupies a square that has any of a particular kind of habitat in it, you may claim that habitat. For example, if you have any bright green eelgrass in your square, you are protected by the eelgrass.
habitat and tide zones
Habitat and tide zones
  • The estuary playing board is divided into three areas – low, mid, and upper estuary which are divided by lines across the board.
  • The low tide line is marked in black.
  • The habitat zones cross over these areas.
  • To claim a habitat, at least 50% of your square must be covered by this habitat.
  • Four habitat zones exist
    • Eelgrass (bright green)
    • Open water (blue)
    • Mudflats (brown)
    • Salt marsh (dark green)
