Areas Closed to Shell Fishing (The user selects whether
to include this parameter.)
Having a non-zero value for the attribute "shell" means this site
is a higher priority – depending on the cause and length of the closure.
Areas not represented at all should also receive a priority value of 1 because
they are not closed, and thereby assumed to be suitable for shell fishing if
shellfish exist at that location. Zeros in the data represent land areas and
are treated as those not represented, and receive a priority value of 1.
