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.
