have a higher caloric density than fish meal. Cur- 

 rently the most important nutrient in condensed 

 fish solubles is the unidentified growth factor be- 

 cause significant growth responses can be dem- 

 onstrated with poultry and other species of live- 

 stock under field conditions as well as in the lab- 

 oratory.
