Fig. 5. Primary trophic connections of macroplankton and nekton in the 

 tropic oceanic pelagic zone, on the example of the diet of the bluefin (1) 

 and yellowfin (2) tunas: 1-3, food connections of the tunas: 1, most 

 important {>10% of arbitrary re-established weight of diet); 2, less 

 important (5-10%); 3, still less important (<5%); 4, food connections with 

 other nektonic and macroplanktonic organisms (according to Borodulina, 

 1974).
