investigations made in the fisheries laboratory. The 
exhibits in the case are :—

more important food matters of each, according

2. A series of useful and useless fishes which compete 
with one another by eating the same food. Three 
pairs of such fish have been chosen for exhibition, 
and in each case the food has been placed between 
the useful and useless (or rather, unmarketable) 
fishes that eat it. The pairs are the Whiting 
and the Angler fish, which both feed on smaller 
fishes; the Cod and the Pogge, which both feed 
on Crustacea; and the Sole and the Solenette, 
which both feed on Annelids.
