 cance of jellyfishes in Mississippi Sound with 

 quantitative data on the associative behavior 

 of small fishes with medusae. Transactions of 

 the American Fisheries Society, vol. 98, No. 

 4, p. 703-712. 



During August, mature blue crabs com- 

 monly were observed perched on the exura- 

 brellae of swimming sea nettles. They did 

 not feed on the medusae but may scavenge 

 on fish the jellyfish stun or kill. Stomach 

 analyses of sea wasps revealed many crab 

 zoea and megalops larvae.

Reported 17 blue crabs caught between 

 November 1902 and May 1903 near 

 Halifax. The recorded northern limit of this 

 species; considered a natural rather than an 

 introduced population.

1955. Variation in morphometry of the adult 

 female blue crab, Callinectes sapidus 

 Rathbun. M.S. thesis, University of Delaware, 

 Newark, 69 p. 



Morphometric variations (length, depth, 

 eye-spine, spine, and width measurements) 

 of adult females were studied within an 

 estuary, between yearclasses, and between 

 populations of different bays. It was postu- 

 lated that low salinity waters permit crabs 

 to attain a larger mature size than do 

 waters of higher salinities.

 vol. 2, No. 2, p. 3-5. 



Distribution, fishery, and food. Life history 

 similar to that in Chesapeake Bay. Size 

 variation between crabs may be due to 



salinity differences in their environment. 

 Tagging data from the Chesapeake, Chinco- 

 teague, and Delaware Bays indicate little 

 mixing between populations in these 

 waters.

1954. Histology of the neurosecretory system 

 of the blue crab Callinectes sapidus. Anatom- 

 ical Record, vol. 120, No. 3, p. 716. 



Six types of neurosecretory fiber termina- 

 tions in the sinus gland of the blue crab 

 were differentiated by staining techniques. 

 They appear to be grouped separately in 

 the sinus gland.

Most observations were made on Callin- 

 ectes ornatus, C. sapidus, and Carcinides 

 maenas. Deals with six types of neuro- 

 secretory cells in the nervous system, the 

 distribution and structure of these cells in 

 living and fixed tissues, the control of 

 electrical and secretory activity of the cells, 

 and the chemical nature of their hor- 

 mones.

 p. 23-25. 



Crab meat packed in fiber and tin cans and 



placed in crushed ice, remained fresh 



equally long in the two types of containers. 



The importance to meat quality of proper 



icing is shown and suggestions for icing are 



given.
