I came across this while googling for crab fishing info. This is an interesting report produced for the State of Maryland by the Cap Log Group in May 2011. It provides a financial and catch overview of the Maryland Blue Crab industry including crab prices (by month, year, type, etc.), overall revenue, license holders/types, gear, harvest, waterman characteristics (age, etc.), landings in different zones, and other information. Very interesting reading even for recreational crabbers - all in 28 pages.
