Loxothylacus texanus infestation of blue 

 crabs in the Gulf of Mexico. An increase in 

 quantities of the parasite could result in a 

 serious and long lasting condition. Method 

 and effects of infestation described.

Review of blue crab fishery of the United 

 States by region; gross composition, 

 protein and mineral content of blue-crab- 

 meat, and marketing and quality of meat 

 (Vol. 1, Chapter 14, Fish, shellfish and 

 Crustacea, by M. E. Stansby). Various 

 methods of preservation of crab meat are 

 presented (Vol. 2, Chapters 10 and 13).

A short section on the blue crab gives the 

 size of the pack (never more than 

 2,000-3,000 cases) and lists obstacles to the 

 development of an Atlantic crab-canning 

 industry.

Blue crabs account for 90 percent of the 

 production of crab meat in the United 

 States. Obstacles to a larger industry are 

 small size of the crab, the closeness of the 

 fisheries to centers of consumption, and, 

 most important, that the meat is subject to 

 discoloration. A method of overcoming 

 discoloration is reviewed.

 crab population (Callinectes sapidus). Chesa- 

 peake Science, vol. 7, No. 3, p. 164-170. 



Abundance of the blue crab in Rhode 

 Island has decreased during the last 30 

 years. Composition of the plasma and 

 muscle was studied to see if abnormalities 

 could be recognized. Groups of correlated 

 tests, such as the inverse relation of the 

 concentration of nonprotein nitrogen and 

 phosphate to chlorinity, were reported to 

 have predictive value and might be applied 

 to the management of the fishery.

Osmoregulatory adaptations in larvae of C. 

 sapidus are discussed. Newly hatched blue 

 crab zoeae lose their ability to hyper- 

 regulate and respond as osmoconformers 

 during the middle of their development but 

 recover hyperregulation within 48 hours 

 and retain it to adulthood.

 Tank experiments were conducted with

 echinoderms, and crustaceans (including 

 those of the genus Callinectes).
