Appendix IV 



Cbustaceans of Economic Valtte in the Chesapeake Bay and the Adjacent 

 Continental Shelf Watees 



I. Species actively exploited 



1. Blue crab, CalUnectes sapidus. In all saline and bracliisli waters of Mary- 

 land, Virginia, and in inshore waters of the shelf ; exploited as hard crabs, soft 

 •crabs and peelers (for bait), and crab meal from the picking residues. 



II. Species giving substantial financial return, but fishing is incidental to other 

 fishing operations. 



1. Northern lobster, Homarus americanus. On the continental shelf. 



III. Species w^hich do not contribute significantly to the economy, because catch is 

 small, local and seasonal. These species are economically valuable in other 

 areas of the U.S. 



1. Edible shrimp (3 species), Penaeus setiferus, P. duorarum, P. aztecus. 

 Caught in fish pound nets, by hand dipnet, and small seine, at mouths of Virginia 

 rivers. 



2. Rock crab, Cancer irroratus. Caught incidentally in deep waters of the Bay 

 and on the continental shelf. Cooked for crab meat extraction. 



IV. Species which are abundant and are exploited, but do not contribute signifi- 

 cantly to the economy here or elsewhere. 



1. Grass (glass) shrimp, Palaem,onetes sp (3 species) . Found in the Chesapeake 

 area ; used as chum (bait) in fishing. 



V. Species which are relatively abundant, and not presently exploited in the Bay 

 area. Other, similar species are exploited in other areas of the U.S. 



1. Sand shrimp (Crangon septemspinosa. Small-sized shrimp, 1-2 inches, most 

 numerous near mouths of Virginia rivers, in fall, winter and spring. 



Used in other areas of U.S. as bait and for shrimp meal (seasoning) . 



2. Fiddler crabs, Uca sp. There are three species abundant in marshes through- 

 out the Bay area. Used in other areas as bait for tautog.
