24 REPORT OF THE COMMISSIONER OF FISHERIES. 
the total output of the former species being 384,000, while 2,130,000 
grayling were distributed in local waters, as compared with an out- 
put of 400,000 in 1914. 
A large run of rainbow trout occurred in Cottonwood Creek, a 
tributary of the Klamath River, in California, much earlier in the 
season than usual, and while the egg collections did not come up to 
the anticipations based on the numbers of fish in the creek, 2,674,900 
were secured, constituting the largest take ever made at this point. 
The work of the 26 stations where pond fishes are propagated was 
conducted along the same general lines as in the past, but on account 
of the generally favorable climatic conditions prevailing during the 
spawning season of the various species, the results were unusually 
gratifying, material increases being made in the output of large- 
mouth and smallmouth black basses, crappies, sunfishes, and cat- 
fishes. The distributions of the largemouth and smallmouth black 
basses were especially satisfactory, that of the former species amount- 
ing to 2,190,000, as compared with 822,000 in 1914, while the distri- 
butions of smallmouth black bass in public and private waters 
aggregated 734,000, as opposed to an output of 187,000 the previous 
year. 
The output of the following stations is deemed especially note- 
worthy:

The success of the operations was due largely to a more compre- 
hensive knowledge of the requirements governing pond-fish culture. 
the adoption of more modern methods, and the promptness in making 
distributions. 
PROPAGATION OF MARINE FISHES. 
Notwithstanding the incessant storms that hampered the cod opera- 
tions off the Massachusetts coast and the shortage in the take of brood 
fish of several of the species propagated, the work of the New England 
stations devoted to the cultivation of the marine fishes was in general 
satisfactory. 
At the Boothbay Harbor, Me., station 16,482 brood lobsters were 
placed in the Pemaquid pound in the fall of 1914 and closely cared for 
throughout the winter, quantities of small pollock and herring being 
given them as food. When they were taken from the inclosure in 
April for the stripping of their eggs, it was ascertained that a larger 
percentage had survived confinement than in any preceding year in 
the history of the station, the number removed being 18,917. ‘The 
lobsters were not particularly well seeded, however, as the yield of 
eggs averaged less than 12,000, but the total number—164,450,000— 
was in excess of any former year’s production from impounded stock. 
After their eggs were removed the lobsters were turned over at the 
prevailing market price of 14 cents a pound to the Maine fisheries 
authorities, who returned them to the open waters of the ocean off 
the Maine coast, and later delivered to the Bureau in exchange egg- 
bearing lobsters of an equal value.
