Food ranges of various fish of the Barents Sea (Brotzky, Briskina, Bogorov, and others). 1 Ammodytes tobianus; II Careproctus reinhardti; III Gadus poutassou; IV Liparis major; V Gymna- canthus tricuspis; VI Myoxocephalus quadricornis; VII Icelus bicornis; VIII Lycodes pallidus; IX Arted- iellus europeus; X Aspidophoroides olrickii; XI Tri- glops pingeli. Repletion indices given by numerals under circles. White sectors inside circles denote per- centages of empty stomachs. 1 Full stomachs; 2 Empty stomachs; 3 Pelagic crustaceans; 4 Bottom- living crustaceans; 5 Benthos; 6 Fish; 7 Sea-bed soil. ray {Raja radiata) consists of pelagic organisms (60 per cent) with 20 per cen- fish and 20 per cent crustaceans and, to a lesser extent, benthos. Ray does not touch infauna at all, it chooses the mobile benthos forms such as bottom crust taceans and worms. Hence ray can be compared with cod as regards its feed- ing habits. Among fish it chooses caplin, cod, haddock and long rough dab, among the pelagic crustaceans Pandalus borealis and Thysanoessa. Various non-commercial Barents Sea fish (M. Briskina, 1939) are typical benthophages (Fig. 70), which tear out the infauna from the bottom, as for example Artediellus europeus; others fatten on infauna, onfauna and on.
