3. Research on nutritive value of waste as a source of food 

 for tetchery fish. 



4. Use of waste as a source of vitamin A oils. 



5. Research on processing waste to prepare an edible salmon 

 oil for human consumption. 



6. Research on development of new products from Alaska salmon 

 cannery waste. 



It«n 1 above is treated completely in Part I, while Items 3 and U 

 are discussed in a preliminary way. The latter two subjects will re- 

 ceive further treatment in Part II as will the other items after further 

 research has been completed. 



Preservation of the salmon cannery waste is a problem of such mag- 

 nitude, it was decided not to undertake any work in that field until some 

 of the other problems had been solved. It is recognized that no solution 

 to the problem of Alaska salmon cannery waste utilization can be reached 

 until adequate means of handling the huge gluts of material are devised. 

 It is believed that this problem can be better attacked after some in- 

 dication is obtained as to wtet portions of the waste are most apt to be 

 utilized. At any rate, facilities and personnel available at the early 

 stages of the project did not permit consideration of the preservation 

 problen at this time. 



POSSIBILITY OF DF;ELCPMENT OF NEW PRODUCTS FROM SALMON 

 CAN^ERY WASTE: LITERATURE SURVEY 



By G. Ivor Jones and Edward J. Carrigan 2/ 



Introduction 



One of the projects initiated during an investigation of the possi- 

 bility of a better utilization of Alaskan salmon cannery waste was the 

 development of new products. The term new products is Lised here to in- 

 clude isolated substances and special preparations not at present pre- 

 pared from salmon cannery waste and which could be used in the pharmaceuti- 

 cal and chemical industries. When it appeared that there might be an ec- 

 onomic ad\-antage in using salmon cannery waste as a raw material source, 

 other industrial applications were also considered. 



Before starting the actual chemical studies and pilot plant opera- 

 tions, it was deemed essential that a survey of the chemical literature 

 be made. A thorough review of Chemical Abstracts was made starting with 

 volume 1. Abstracts were selected on the basis of any reference to the 

 chemical composition of fish and fish organs. Also recorded were references
