of New England haddock was demonstrated by the analysis of the 

 data accumulated in previous years (Schuck, 1949). Other in- 

 vestigations were concerned with the flounder fishery, census 

 of all fish populations over the entire New England banks area, 

 and hydrography of fishing areas. 



Shellfish investigations were conducted by Galtsoff only 

 during the summer. These studies pertained to the physiology 

 of feeding of the oyster and with the fertilization and cleavage 

 of oyster eggs. All cytological work was performed by Eugenia 

 Galtsoff. The Laboratory was also used for the study of the 

 material collected by Galtsoff during his expedition to the Gulf 

 of Panama and Gulf of Chiriqui to determine the cause of the 

 precipitous decline in the pearl fishery. Tissues of the pearl 

 oyster, preserved during the expedition, were microscopically 

 examined, and the mollusks and other invertebrates found in 

 association with the pearl oyster were identified. Only four 

 independent investigators used the facilities of the laboratory. 



Pending the proposed transfer to Boothbay Harbor, the 

 administrative headquarters of the Clam Investigations were 

 located at the Woods Hole Station. Observations on the feed- 

 ing of the soft- shell clam were made jointly by John Barlow 

 and personnel at WHOI. 



The headquarters of the shellfishery investigation at 

 College Park, Md., were closed in 1950 and Galtsoff, former 

 chief of the section, was permanently assigned to the Woods 

 Hole Laboratory to conduct research necessary for the pre- 

 paration of a comprehensive treatise on oyster biology. The 

 Woods Hole Laboratory was also used in the preparation of a 

 comprehensive book about the origin, waters and marine life 

 of the Gulf of Mexico. In connection with this undertaking, a 

 large bibliography comprising several thousand cards was pre- 

 pared and is now kept in the library of the Fisheries Biological 

 Laboratory and in the library of the MBL at Woods Hole. Addi- 

 tional copies were distributed among the participating institu- 

 tions of the Gulf area.
