Description

This dataset includes data from blue mussels (Mytilus edulis) density surveys. Large mussel beds in coastal eastern Maine were sampled from 2014 to 2017.

Methods & Sampling

Sampling and Analytical Methodology:
Density of blue mussels (Mytilus edulis) was randomly sampled at each of the major mussel beds (stations) along the eastern Maine coast from Frenchman Bay to the Canadian border. Sampling followed a nested design of 4 plots (30 cm x 30 cm) randomly distributed along a 6 meter transect, and three transects randomly spaced in a random subarea within the greater mussel bed. This process was repeated for at least three subareas per year per mussel bed. Where densities of mussels were too great, plots were subset into a 5 x 5 grid, and the average density of 3 randomly chosen grid sections measured, and the mean extrapolated to the entire area of the plot.
