Notes on Hybridization 



C. E. Crompton, of Duckabush, 

 Wash., has reported interesting observa- 

 tions regarding the results of crossing 

 the female chum salmon Oncorhynchus- 

 keta with the male humpback 0. gor- 

 buscha. 



The development was normal with 

 small percentage of loss, and the fry 

 were very vigorous, smaller than chums, 

 yet larger than humpbacks of the same 

 age. In early development certain color 

 changes were noted and the parr marks 

 were retarded as compared with chum 

 fry. An interesting fact was that two 

 distinct color types became apparent at 

 an age of about 25 days. About one- 

 third of the number strongly resembled 

 the humpbacks in their beautiful green 

 coloring and absence of Parr marks, 

 while the remainder developed irregular 

 markings on the hack and parr marks 

 on the sides, the general color deepening 

 with age to a dusky green similar to that 

 of the chums. Serious abnormalities 

 occurred in later stages and many fish 

 died, but the majority survived in good 

 condition. A few hundred are retained 

 for further observation. — Fisheries
