REPOKT OF COMMISSIONER OF FISH AND FISHERIES. XXXIX 



taken to resume the work. Provision was made in 1887 for salmon 

 natching on the Columbia River, and Mr. Stone was directed to establish 

 a station somewhere on this river or its tributaries. A site was chosen 

 on the Clackamas, and arrangements made for beginning work the 

 ensuing season. Applications have been received up to the present 

 time for several million salmon eggs, from parties on the small coast 

 rivers, who offered to receive and hatch the eggs and distribute the 

 young fish at their own expense. 



The Atlantic Salmon (Salmo salar). 



Eggs of this species are collected and hatched at the Bucksport Sta- 

 tion. From there consignments are forwarded to various State com- 

 missions who have contributed to the expense of handling them. At 

 this station the plan of rearing salmon until they have reached a length 

 of several inches before turning them out was begun in 1888. See under 

 the Maine Stations for fuller details. 



At Craig's Brook there was a great loss of salmon during the sum- 

 mer, probably on account of the low stage "of the water. The temper- 

 ature of the water became high, and on the morning of July 5 an ex- 

 treme of 72° F. was recorded. 



The spawning season began October 25 and ended November 5; 

 1,184,000 eggs were taken. The average number of eggs per female 

 was 8,691. 



The loss up to the final shipment was 7.1 per cent. The average tem- 

 perature in November, 1887, was 42.3° ; in December, 34.8°. In Jan- 

 uary, 1888, 33.5° ; February, 34.5°. 



500,000 eggs of this species were received at the Cold Spring Harbor 

 Station, from Bucksport, Maine, and nearly all of them were planted as 

 fry in the Hudson River and Long Island waters. During the months 

 of May and June, of 1888, salmon were caught in the Hudson by shad 

 fishermen. Commissioners Blackford and Burden estimated that over 

 300 adult salmon were taken from the river between Gravesend Bay 

 and the dam at Troy. 



The Landlocked Salmon (Salmo salar var. sebago). 



An account of the number of eggs of this species taken, and their 

 distribution, will be found under the heading of the Maine Stations. 



The salmon made their appearance at Grand Lake Stream early in 

 September, 1887. A trap inclosing several acres of water, of a max- 

 imum depth of 20 feet, was made to retain salmon. October 25, the 

 inclosed fish were found to have begun to form ridds. The first eggs 

 were taken October 26. The inclosure was cut several times by musk- 

 rats. The total catch of salmon was 154 in excess of that of 1886. The 

 heaviest fish taken was a female weighing 5 pounds 7 ounces ; this was 

 caught November 13. In 1887 only one marked fish was seen, and that 

 appeared to have been marked in 1885 ; none of the fish marked in 1886 

 were observed.
