BULLETIN OF THE BUREAU OF FISHERIES 
The experiment at Uganik Bay was made by the senior author and that at Nicholaski 
Spit by L. G. Wingard, assistant agent, Alaska Fisheries Service. 
SOUTHEASTERN ALASKA, 1927 
These experiments were designed primarily to supplement the data secured in 
1924, 1925, and 1926. While, in general, the results have merely confirmed those of 
previous experiments, it has seemed best to publish the data in full on account of the 
importance of corroborating our findings. It may be pointed out here that when the 
results of two or more entirely independent experiments run parallel the probability 
that they are valid is greater than in the case of a single experiment involving an 
equal number of individuals. Whenever the new data agree closely with those 
secured previously, the reader will merely be referred to the earlier reports, which 
contain adequate discussions that need not be repeated here. 
Owing to the exceptionally light run and the late appearance of the fish in all 
districts, only 4,668 salmon were tagged during the entire season. Commencing in 
the Chatham Strait and Icy Strait districts, operations were moved gradually south- 
ward with the appearance of the fish. The salmon run in the southern district, 
however, proved to be exceptionally light, and only a few hundred fish were tagged 
in the vicinity of Gravina Island in Clarence Strait. In all districts the experiments 
showed the fishing gear to be working very efficiently, and in some instances more 
than 50 per cent of the fish tagged were recaptured. It was the policy of the bureau 
to tag the salmon when conditions were most favorable and, whenever possible, just 
prior to a weekly closed period, thereby giving the fish every opportunity to make 
headway on their course. A close watch was kept of the fish tagged, and at no time 
did they appear sluggish or linger around the scene of operations after they were 
liberated. 
The two previous reports (Rich, 1926, and Rich and Suomela, 1927) contain maps 
showing the distribution of the tagged fish, and it has not seemed necessary to 
republish these maps here. Those reports also contain lists of minor localities not 
shown on the maps.
