There is nothing brought out by Tables IL and III. that seems to call 
for special remark, unless it be the occurrence of a considerable number 
of the rather uncommon Bivalve Mollusc Pecten semis in some of the 
stomachs sent from Lybster. This species of Pecten, which is a very 
small one, though not very commonly met with, is gregarious in its 
habits and therefore likely to occur in considerable numbers in places 
frequented by it. Echinoderms, especially the Ophiuroids, are shown 
here, as in previous statistics, to form the largest part of the haddock’s 
food. Crustacea and Mollusca rank next in importance. Among the 
Annelids, the ‘Sea Mouse’ seems to be specially relished by the haddock. 
It will also be observed that all the Molluscs were either young or, if 
adult, were small species. 
In previous Reports there are several extensive accounts given of the 
nature of the food of fishes, which was a subject that early called for 
attention. In the Fourth Annual Report! there is a special paper on the 
food of the haddock, to which this may be regarded in some respects as 
supplementary. ‘The tables given in the paper referred to are extensive 
but the results of these later investigations are in general accord with the 
conclusions given.
