Callinectes sapidus. Journal of Parasitology, 



vol. 33, No. 2, p. 146-150. 



Nonovigerous females which have already 

 spawned once can be distinguished from 

 nonspawning females by the examination 

 of their gills for this parasite. Large red 

 worms indicate previous spawning; no 

 worms or only small white worms indicate 

 the crab has never spawned.

The color difference of the female blue 



crab is probably due to the nature of the 



carotenoid-protein link or to the structure 



of the protein involved.

portunid crabs. Crustaceana, vol. 5, Pt. 3. p. 



238-239. 



Investigation of the carotenoid pigments 

 found in the exoskeleton of the blue crab 

 showed sexual dichromatism. Female has 

 orange fingers on the chelae as compared to 

 the male, whose fingers are white and blue. 

 Also examined, Ovalipes ocellatus and O. 

 quadulpensis.

 concentrations of adult blue crabs (Callinectes 

 sapidus Rathbun). Biological Bulletin (Woods 

 Hole), vol. 125, No. 3, p. 499-507. 



There was no correlation between size of 

 adult females, adult males, or females in 

 sponge and mean serum protein or copper 

 concentrations. Means of males were lower 

 than those for all females; sponge females 

 were higher than nonsponge females. In the 

 same width-class, males tended to be longer 

 than females.

 estuarine animals. Association of South- 

 eastern Biologists, Bulletin, vol. 10, No. 2, p. 

 30. Abstract only. 



Sediment, labeled with radioactive gold, 

 was released into Cape Fear River, N.C., to 

 determine the effect on caged blue crabs, 

 oysters, mummichogs, and Atlantic 

 croaker. Oysters accumulated the most 

 radioactivity followed by crabs and fish. 

 Concluded that the amount of radioactive 

 gold used did not harm the marine com- 

 munity.

In this review of more recent work on 

 crustacean metabolism, references to the 

 blue crab include enzymes and inhibitors of 

 the glucuronate pathway system, cause of 

 hyperglycemia in intact or eyestalkless 

 crabs, gill mitochondrial enzymes, and 

 effects of salinity on the rate of oxygen 

 consumption and enzyme activity.
