TIMS OF SPAWNING MIGRATION 



Under this heading are grouped two categories of data, the time a 

 particular species returns from the ocean to the river mouth, and the time 

 the species migrates upstream. 



If a paper contains a statement that would restrict the time of 

 return of the mature fish to their appearance offshore in the vicinity of 

 the stream mouths, the reference is included in the first category. Should 

 data be recorded on the time a mature fish are observed migrating upstream 

 at any point in its course, the paper is cited in the second category. To 

 facilitate compilation and comparison of data, the references are arranged 

 geographically.
