Estuary Survival The Rules of Life
Dungeness crab – Cancer magister 5mm across carapace – megalops 12mm across carapace – 1 st instar 20mm across carapace - juvenile
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 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 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)
Your scorecard Investigator’s name Common name of the animal Genus and species Size and life stage Three questions Scoring box for each round
sample scoring for 3 rounds PositionHabitatFate C7Eelgrass My crab survived an oil spill because he was in the mid- estuary. C7Eelgrass My crab survived because the eelgrass provided cover from cormorants. C7Eelgrass My crab grew one size class because the high tide brought food from the ocean.
