Salmon Food. 



The stomachs of 727 fish were opened at the Company's Fish House. 

 Of this number only 45 contained food recognisable as such. The food 

 was preserved and was handed to Mr H. C. Williamson, M.A., B.Sc, at 

 the Marine Laboratory, St Andrews, for examination. The stomachs of 

 74 salmon examined at Kelso during the rod season contained no food, 

 but all had a quantity of yellow mucus in which was usually a number 

 of tapeworms. 



Mr Williamson's determination of the food is as follows : — 



Fishes. 



Herring, tail gone, inches long ; the muscles for about 1 inch in 

 front of the tail are digested off. The skin alone of the remainder of the 

 fish has disappeared. 



Herring, head gone, 6|- inches long ; the muscles of the anterior fifth of 

 the trunk have been completely digested, the remainder partially digested. 



Herring, tail gone, 7f inches long ; the muscles of the posterior half of 

 the body have been digested ; the muscles of the anterior half of the body 

 and the head are half digested. 



Herring, portion of head and portion of tail gone, 7f inches long ; the 

 muscles of the posterior half of the body have been digested ; the muscles 

 of the anterior half of the body are partially digested.
