Statistical evidence did not support claims 

 that hydraulic clam dredging caused a 

 decline in blue crabs or commercial fishing 

 in the Eastern Bay -Miles River, Md., area.

 and Wildlife Service, Fishery Leaflet No. 29, 3 



P- 



An experiment on a Maryland farm to 



determine the value of crab scrap as 

 poultry feed indicated that hen and egg 

 weight increased and plumage was better as 

 a result of crab scrap in the diet.

 sodium fluxes in gills of the blue crab, 

 Callinectes sapidus. Comparative Biochem- 

 istry and Physiology, vol. 20, No. 3, p. 

 743-753. 



Measured were blood sodium concentra- 

 tions at various salinities, oxygen consump- 

 tion of gill pieces, potential differences 

 between blood or isolated gills and 

 medium, and sodium fluxes across the gills.

 heterogeneity of hemocyanin and on a

 193-208. 



Sera of the blue crab, one of the three main 

 species studied, showed some qualitative 

 and considerable quantitative variation. 

 Parasitization by Loxothylacus increases 

 the amount of "fast" hemocyanin and of a 

 certain protein.

1966. Carteret County seafood processing 

 project. Part 1. U. S. Department of Com- 

 merce, Economic Development Administra- 

 tion, Technical Assistance Project No. 777. 

 Contract No. Cc6161. 94 p. 



A study on the seafood fishery of Carteret 

 County, N.C. Part 1 project was to deter- 

 mine if there are sufficient and suitable raw 

 materials for processing endeavors. Market- 

 ing and shipping of whole and processed 



blue crabs. Catch statistics. Crab meat was 

 one of the products produced by a proto- 

 type plant. The quality of plate-frozen 

 meat was good after 60 days of storage. 

 The number of shell pieces in the finished 

 product was reduced.

 project. Part 2. U. S. Department of Com- 

 merce, Economic Development Administra- 

 tion, Technical Assistance Project No. 

 03-6-09022. Contract No. C-194-66. 79 p. 

 Part 2 project was to determine how to 

 expand the variety and extent, while 

 improving the quality, of Carteret County, 

 N.C, seafood landings. Operations of crab 

 dealers, catching methods, catch by season, 

 prices, fishing grounds, and preparation for 

 shipment. Trawl fishing for crabs suggested 

 as a new local fishing method.

 programs on the blue crab.

Deals with the life history of the blue crab 

 and the appearance of egg-bearing females 

 in upper Chesapeake Bay where newly- 

 hatched crabs die because of low salinities.

News, vol. 7, No. 4, p. 5. 



Report of a large male crab caught in 

 Maryland whose back was brilliant blue, 

 the same shade usually found only on the 

 claws and legs. 



1953. Concerning loss of crabs in pots. 



Maryland Tidewater News, vol. 10, No. 1, p. 



1-2. 



An investigation indicated that blue crab 

 deaths in pots were due to low dissolved 

 oxygen resulting from organic detritus and 

 the influx of deeper waters having little 

 oxygen into areas where pots were set.
