1969. The problem of automating crab pick- 

 ing continues to defy solution. National 

 Fisherman Yearbook Issue, 1969, vol. 49, No. 

 13, p. 111-112. 



A report (FMC Corporation, Santa Clara) 

 on the progress and effectiveness of crab 

 picking machines developed by the Bureau 

 of Commercial Fisheries and by private 

 industry. Concluded that several private 

 machines could be available for the 1968 

 season, but that none would pick meat 

 equal to the quality of lump meat picked 

 manually. Comments on the report by 

 various crab packers are included. Outline 

 of a four phase Bureau of Commercial 

 Fisheries program for further development 

 of automated picking.

1965. The blue crab in Florida. Florida Board 

 of Conservation Marine Laboratory, Salt 

 Water Fisheries Leaflet No. 1, 17 p. 



Description of the blue crab and how it 

 differs from similar species in Florida. The 

 author provides data on distribution, life 

 history, growth, food of zoeae, parasites, 

 fishing gear, fishing methods, and produc- 

 tion of soft shelled crabs. He also discusses 

 the requirements and the feasibility of 

 raising blue crabs in ponds.

 virgin ica Gmelin. U.S. Fish and Wildlife 

 Service, Fishery Bulletin, vol. 64, 480 p. 



There is no evidence that blue crabs are 

 attracted specifically by oysters, but it is 

 apparent that they destroy small oysters in 

 clusters by cracking their shells.

1965. The occurrence of the American blue 

 crab, Callinectes sapidus Rathbun, in the 

 coastal waters of Lebanon. Doriana, vol. 4, 

 No. 160, p. 1-3. 



The range of the blue crab in the Mediter- 

 ranean was extended to the coast of 

 Lebanon on the basis of 13 specimens from 

 St. George Bay, Beirut. Ovigerous females 

 occurred in February and March. The 

 barnacle, Chelonibia patula was attached to 

 some specimens.

 of strobane, DDT, and BHC to tidal marshes 

 in Delaware. Journal of Wildlife Management, 

 vol. 21, No. 1, p. 42-53. 



Mortalities of caged crabs and fish, placed 

 in streams and ponds sprayed with insecti- 

 cide, were noted for 7 days after applica- 

 tion. Deaths of adult blue crabs in treated 

 plots were not significantly greater than in 

 untreated plots nor were there differences 

 among any of three treatments. A decline 

 in crab-pot catches indicated an avoidance 

 of sprayed areas.
