 crabs are discussed.

A peripheral infection which does not 

 retard development of crab eggs in the 

 interior of the sponge. Not over 25 percent 

 of the eggs are infected and only about 25 

 percent of the sponges in samples from the 

 lower Bay were heavily infected. Fungus 

 developed rapidly in salinities from 5 to 30 

 p.p.t. Forms of Carchesium, Ephelota, 

 Chlamydobacterium, and Carcinonemertes 

 also were found living on the sponge.

 Copper content was estimated in each of 

 35 marine animals, prepared by grinding 

 the entire specimen. The amount of copper 

 in crabs and shrimps was between that of 

 oysters and fishes.

A previously undescribed shell disease of 

 unknown cause was investigated morpho- 



logically, histologically, and bacteriologic- 

 ally. The disease appears as a superficial 

 necrosis of the exoskeleton that progresses 

 from a few spots into widely necrotized 

 areas. Skeletal tissue is digested and 

 broken.

The channel, by raising salinities, should 

 not greatly affect the fishes of the area but 

 should have an adverse effect on abundance 

 of the blue crab. Younger stages of crab 

 were most abundant in the least-saline 

 waters, decreasing significantly as salinity 

 increased. The project would also result in 

 losses of nursery habitat. Presents estimate 

 of seasonal abundance of blue crab by size 

 and by area.

Blue crabs were fairly evenly distributed in 

 estuaries of Everglades National Park, Fla. 

 Ovigerous females were found throughout 

 the year. Crabs ranged in size from 30 to 

 209 mm. and occurred at salinities from 

 to 55 p.p.t. and at temperatures from 16 to 

 31° C.

Foods tested were inadequate for rearing

 occurred between zoeae from different 

 parents reared under identical conditions.
