It was hoped that much more detailed information as to the mi- 
gration up the Fraser River might be presented, and to that end the 
river and the waters of the Strait of Georgia around the mouth of 
the river had been divided into 20 regions, each comprising about 5 
miles of the river or offshore about the mouths. The returns from 
Canada were at first studied on this basis, but it finally became clear 
that the subdivisions were much too small to give results of any 
significance. These 20 regions were then combined into 7, as follows: 
Region 10. Banks off the mouth of the south arm and Canoe Pass. 
Region 11. South arm and Canoe Pass up as far as Deas Island. 
Region 12. South arm from Deas Island to New Westminster. 
Region 13. Banks off the mouth of the north arm. 
Region 14. North arm. 
Region 15. Fraser River from New Westminster to the mouth of Pitt River. 
Region 16, Fraser River from the mouth of Pitt River to Mission Bridge.
