 losis and ulcer disease. The nunnber of survivors in each group are compared

2. Study of the Relationship Between Trout Hybrids and Parental Strains Using 

 Serological Methods

 hybrid trout crosses and parental strains developed through the breeding pro- 

 gram at the Benner Spring Research Station. Studies are made of serological 

 cross-reactions that may occur between such strains and crosses.
