Abstract

The aim of this experiment was to determine if Carcinus Maenas (European Green Crab) hhas a habitat preference in Seadrift Lagoon located in Stinson Beach, California. This experiment was accomplished by placing crab traps on the two types of substrate in Seadrift (sand and algae). The traps were pulled up every 24 hours and the size and sex of crabs was recorded. The data was analyzed to see if there was a difference in habitat preference based upon size, sex, and number of crabs. Using a Poisson Regression model, the size and sex of crabs were not significantly different between treatments. Using General Linear Hypothesis Tests the number of crabs in algae were significantly different from the number of crabs in sand, control, and cage control traps.
