The fish-cultural work of this station covers a period of eight months, 
and was conducted chiefly by the resident employés of the station. In 
the propagation ofscod the. force was increased by the assignment of 
Mr. Richard Dana, who was placed in charge, the period of active work 
being from October 14, 1889, to April 4, 1890. 
Cod.—As a source of egg supply, 3, 403 adult codtish were obtamied 
from fishermen October 22 to Noweniben 19, 1889, and placed in live- 
ears and in one of the tidal basins. Here, under as natural conditions 
as practicable, the brood fish were held to await maturity, when they 
were stripped of their eggs every two or three days until the supply 
was exhausted. Many of the adult fish died immediately after being 
placed in the inclosures, the temperature being then 55° I’., and some 
died each day until the water temperature fell to 46°. A great many 
became blind, and it was supposed to be caused by the glare of the 
sunlight, the water being shallow. 
In the two months following 91 fish yielded 8,545,700 eggs, and from 
these there were hatched and liberated in local Here when from three 
to six days old, 5,861,100 fry. At the termination of the spawning 
season there were remaining on hand 1,000 of the brood fish, which were 
retained in one of the tidal basins to determine their value as spawn- 
producers the succeeding fall. On February 11, 1890, 2,374,200 eggs 
received from Gloucester Station were put in process of hatching, with 
the result of 584,700 fry, and a second consignment, April 14, of 621,500 
eggs, from the same source, produced 416,300 fry.
