A 6-month study to determine some of the 

 effects of a large weir (submerged structure 

 in marsh tidal channels to stabilize water 

 levels) on fishery resources. Quantitative 

 sampling indicated that the weir did not 

 serve as a barrier to blue crab movement. 

 Because adults were more numerous above 

 the weir, whereas abundance of young was 

 nearly equal on both sides, the weir must 

 have improved the habitat above it for 

 crabs.

 habitats. Comparative Biochemistry and

Evaporative water loss in the blue crab and 

 10 other brachyuran crabs was related to 

 habitat. Evaporative loss was a function of 

 body weight in all species, and loss 

 increased at higher temperature. Most 

 water loss appears to be through the 

 integument exclusive of the gill chamber.

 adaption to land. Comparative Biochemistry 

 and Physiology, vol. 29, No. 1, p. 423-429. 

 Experiments on blue crabs and seven other 

 species chosen to represent different habi- 

 tats. Most evaporative loss occurred 

 through the shell; loses from dead and 

 living crabs were about the same. Ter- 

 restrial forms were least permeable to water 

 and aquatic species were most permeable.

References to the blue crab include the 

 number and size of eggs, detail of tegu- 

 mental glands of the endopodites, and 

 fixation of eggs to the pleopods (each hair 

 carries about 200 eggs; each egg is glued by 

 a stalk to the hair). Description of zoea. 

 Megalops of Callinectes were observed to 

 pick up grains of sand and place them in 

 their ear sacs (statocysts).

It was estimated that the production of 

 crabs from the South Atlantic and Gulf of 

 Mexico (1938 production, 26 million 

 pounds) had a sustained (ultimate) poten- 

 tial of 50 million pounds if methods of 

 conservation and management were 

 employed.

Blue crabs (p. 273-274) were absent in 

 some areas but were taken (May-July) from 

 the beach to a depth of 18 fathoms. About 

 one-half of the crabs captured in July were 

 ovigerous. High salinity was thought to 

 explain the sparsity of blue crabs in the 

 shallow water off Sabine, Tex. No males 

 were captured in offshore waters.

 Carolina, South Carolina, and Georgia. 

 Examines the importance of commercial 

 fishing in the economy, access to seafood 

 markets, and the supply constraint in the 

 region under current and expected condi- 

 tions.
