 Occurrence of shells, decapods, and some 

 other marine invertebrates. Blue crab shells 

 (cast off in molting) occurred in great 

 numbers in shallow pools in the marsh 

 during April.

 fishery products. U.S. Bureau of Fisheries, 

 Investigational Reports, vol. 1, No. 25, 7 p. 

 Iodine content of crab meal was found to 

 be very high, and therefore, iodine must 

 also be concentrated largely in non-edible 

 portions of crabs.

 waters of Chesapeake Bay. Bulletin of the 

 U.S. Bureau of Fisheries for 1930, vol. 46, p. 

 277-381. 



In a series of cruises, the blue crab was 

 taken infrequently in offshore dredging and 

 trawling in Chesapeake Bay, and most were 

 juveniles. One large catch of crabs was 

 made at a depth of 28 m. at water 

 temperature of 10.1° C.

 blue crab. Ecology, vol. 30, No. 3, p. 

 390-394. 



The best technique for tagging adult crabs 

 employed special Nesbit-type tags wired 

 across the carapace. Various methods were 

 evaluated on the basis of listed assumptions 

 which must be valid before tagging can be 

 successfully used.

The upstream flow of deep water may be 

 essential to the dispersion of young blue 

 crabs in Chesapeake Bay. This flow 

 provides for the annual redistribution of 

 juveniles to all upstream areas, and is one 

 of the forces contributing to the resiliency 

 of estuaries.
