The importance of reducing predators is supported by a matrix model
developed by Barbeau and Caswell (1999), which was used to look at the shortterm
dynamics of seeded sea scallops under various scenarios. The scenarios
include increasing size of seeded scallops, changing the initial density of seeded
scallops, increasing the dimensions of the site and changing the season of
seeding. However, the number one scenario found to increase final scallop
densities was to reduce predator densities, in particular rock crabs and sea stars
which have been identified as the major predators (Barbeau and Caswell, 1999).
