Of these 175 young Dabs, 29 had Mollusca, 



12 had Crustacea, 

 4 had Annelida. 

 The great majority, 129, had their stomachs empty, but 

 they were from a neighbourhood (Kibble, Gut Channel) 

 where we usually find that the adult fish have little or 

 nothing in their stomachs. 



Examination of Food in Stomachs. 



During the past twelve months 4326 stomachs of marine 

 animals have been examined m order to determine the 

 food contents. Of these 4078 will be accounted for in the 

 lists which follow, the remainder are of various species 

 none of which are numerous enough to make them worth 

 recording. Of the 4078 recorded, 3656 are fish proper, 

 while of the remainder 154 are shrimps and 85 shanks 

 (Pandalus annulicornis) . 



In addition to the fish of various sizes recorded in the 

 following table, over 1000 young plaice and dabs have 

 been examined, and these are reported upon separately. 

 The plaice, of which we have a considerable number 

 recorded, nearly 900, show clearly that at sizes of about 

 an inch in length they live mainly on Copepoda, small 

 Cumacea and some Crustacean larval forms, while after- 

 wards they take to a more mixed diet consisting largely of 

 Mollusca and worms. The change of diet, as far as can
