Chignik Lagoon and Chignik Bay, length of fishing 

 seasons, and fishing regulations have varied consider- 

 ably during 1895-1966 (Table 2; Fig. 2). 



Because of the unique time of entry of the Black Lake 

 and Chignik Lake stocks into Chignik Lagoon, to be 

 shown later, the distribution of open and closed fishing 

 periods within each season indicates to some extent 

 which stock was exploited (Fig. 3). In 1954, for example, 

 there was only one short open period which resulted in a 

 fourfold difference in rates of exploitation between 

 stocks. The lengthy season and the large number of traps 

 concentrated in this small area (Chignik Lagoon is about 

 12 km long) indicate an intense fishery from 1900 to 1914. 

 Moser (1902) visited Chignik in 1898 and again in 1900 

 and stated, "the lagoon and approaches and the river ap-
