The table shows several interesting facts. The amounts taken from areas 5, 6, 
and 7 (fig. 8) have decreased, and those from area 3 have increased. The amount 
taken from area 4 by the Red Bluff Bay plant was slight, but those plants located in 
area 3 obtained a large percentage of their 1925 catch from area 4. One of the most 
interesting and significant developments is the exploitation of distant areas, such as 
Noyes Island, Warren Island, Sitka Sound, Icy Strait, and Lynn Canal, in 1927 and ■ 
1928. This may indicate that a greater decrease in abundance has occurred than is 
shown by the catch analysis (to be discussed later, see fig. 47), the catch being main- 
tained by shifting of the fishing grounds. 
The central Alaska fishery is more recent. The western side of Prince William 
Sound has been subjected to intensive fishing since 1918. (Fig. 9.) In Cook Inlet 
gill-net fishing was commenced at Halibut Cove, Kachemak Bay, in 1914, and has 
continued up to the present, purse seining in Cook Inlet not commencing until 1923. 
On Kodiak Island fishing in a small way was being carried on in the vicinity of 
Kodiak by 1916, and Shearwater Bay has been exploited since 1921. On Afognak
