Part III. — Tenth Annual Report 
Arthropods were found in 560 stomachs (87 per cent.). The forms found 
were Portunus in 141 ; Crangon in 117 ; Nephrops in 110 ; Eupagurus 
in 92 ; Pandalas in 80 ; Hyas in 20 ; Galathea in 12 ; Porcellana in 7 ; 
Balanus and Pinnotheres, each in 2 ; Pagurus and Nunida, each in 1 ; 
hermit-crabs, unidentified, in 48 ; unidentified crabs in 18 ; spider crabs 
in 7 ; schizopods in 1 ; unidentified Crustacea in 17. 
Molluscs were found in 76 stomachs (11 per cent). The forms found 
were Buccinum in 30 ; Pecten in 13 ; Solen in 12 ; Turritella in 3 ; 
Fusus in 2 ; Rossia and Scrobicularia, each in 1 ; unidentified lamelli- 
branchs in 12 ; unidentified cephalopods in 2. 
Fish were found in 325 stomachs (50 per cent.). The forms found 
were whitings in 46 ; sand-eels in 22 ; long rough dabs in 19 ; herrings 
in 17 ; Lumpenus in 11 ; pogge in 10; sprats in 7 ; haddocks in 9 ; 
codlings in 5 ; common dabs and cod, each in 4 ; gobies in 3 ; Motella 
in 1 ; gurnards in 1 • unidentified fish in 165. A ctenophore was found 
in 1 ; and medusids in 1. 
It will be seen that arthropods (particularly Crangon, Portunus, 
Nephrops and Pandalus) and fish formed the chief food of cod in the 
Firth of Forth. Molluscs are but slightly represented. Echinoderms and 
annelids are relatively unimportant. 
Haddocks. 
In all 874 were examined, of which 128 were empty: 703 contained 
food that could be identified. 
Echinoderms were found in 208 stomachs (29 per cent). The forms 
found were Amphiara in 71 ; Ophiura in 51 ; Ophioglypha in 26 ; 
Ophiocoma 17 ; Echinocyamus in 15 ; Ophiothrix in 14 ; Asterias in 2 ; 
Holothuria in 1 ; unidentified sand-stars in 11. 
Annelids were found in 166 stomachs (23 per cent). The forms found 
were Aphrodite in 38 ; Priapulus in 11 ; Arenicola and Sabella, each in 
2 ; Nereis, Pectenaria, Sipuncuhis, Polynoe, Echiurus and a planarian, 
each in 1 ; unidentified annelids in 117. 
Arthropods were found in 422 stomachs (60 per cent.). The forms 
found were Crangon in 105 • Ampetisca in 65 ; Eupagurus in 42 ; 
Portunus in 38 ; Diastylus in 18 ; Pandalus and Nephrops, each in 8 ; 
Leucon in 7 ; Atylv.s in 5 ; Hyas and My sis, each in 2 ; Porcellana, 
Galathea, Corystes, and Uiothoe, each in 1 ; amphipods in 31 ; hermit- 
crabs in 30 ; cumaceae in 19 ; crabs in 3 ; unidentified crustacse in 35. 
Molluscs were found in 283 stomachs (40 per cent). The forms found 
were Scrobicularia in 163 ; Solen in 41 ; Phillne in 28 ; Cylichna in 7 ; 
Pecten in 4 : Buccinum in 3 ) Maetra and Montacuta, each in 2 ; Rossia, 
Octopus, Nucula, Actceon, Leda, Corbula, Natica and Psammobia, each in 
1 ; unidentified cephalopods in 2; unidentified lamellibranchs in 22. 
Fish were found in 40 stomachs (5 per cent). They consisted of 
long rough dabs in 2 ; gobies, sand-eels, herrings and pogge, each in 1 ; 
fish ova in 2 ; unidentified fish in 32. 
Ascidians were found in 1. Pleurobrachia was found in 1; Actinoloba 
in 1 ; and medusids were found in 3. 
The haddock would appear to be one of the most, if not the most, indiscri- 
minate feederof all the fish examined,its dietary embracing about 70 different 
species of animals in the Firth of Forth alone. It would appear to eat any- 
, thing that came its way, and to show no very particular preference for any 
"one kind of food with the exception of Scrobicularia, Crangon and some 
annelids.
