UTILIZATION OF THE FISH WASTE OF THE PACIFIC OCEAN. 



71 



Since the whaling industry has undergone a large decline through 

 the depletion of the number of whales, there is little probability that 

 the future will see any marked increase in the production of fer- 

 tilizer from whale carcasses. 



In the following table are reported results of analysis of material 

 prepared from the waste from the sardine, tuna, and whale industries 

 and from dog fish:
