great as 11-13 million tons, i.e., up to 7,200 kg/km^. This level of 

 fish productivity is the highest in the World Ocean. In addition to the 

 anchovies, the pelagic zone is inhabited by tuna, marl in, sauries and 

 squid. Within the limits of the narrow continental shelf are many hake, 

 horse mackerel and mackerel, fishing for which could yield over 1 

 million tons. 



The Southwest Pacific is somewhat different, being populated by 

 such species as sardines, Beryci formes, poutassou, plaice, etc., which 

 make up over half of the still small catch of the region (0.4«10° t). 

 The production here is as yet the least of all regions of the Pacific 

 ocean--only 12 kg/km . Doubtless, the development of fishing in this 

 region, the resources of which are still negligibly used, will allow an 

 increase in the total catch to at least 2 million tons, increasing the 

 useful fish productivity by many times. 



The southernmost regions of the Pacific are in the Antarctic. 

 Here, great resources of Antarctic krill, Serebryanka, etc. wait to be 

 used. 



Indian Ocean. Here, only 2. 7-3. 0*10" t of seafood is caught, 35-40 

 kg/km'^ for the entire ocean. This is significantly less than the other 

 ocean basins. Doubtless, one reason is the insufficiently developed 

 fishing industry, particularly of pelagic fish, but it is thought by 

 most researchers that even significant intensification of fishing, bring 

 the catch up to the maximum possible level of 5-6 million tons, would 

 not increase the fish productivity of the shelf to over 350 kg/km^, of 

 the coastal pelagic zone to over 250 kg/km^. The most productive 

 regions are the coastal zones of the northwestern portion of the ocean, 

 particularly the Gulf of Aden and Bay of Bengal, the waters of the east 

 African coast, the regions of Madagascar and the Seychelles Islands, as 

 well as the open regions of the ocean in the areas where masses of water 

 of different origins come into mingle. 



Species fished for here include sardines, large and small tuna, 

 mackerel, sharks, as well as Sciaenidae, Lucyanidae and other benthic 

 fish. There are many squids and lobsters (off the coast of Africa), 

 shrimp and other commercial invertebrates. In the regions around the 

 subantarctic, there are several species of fish (nototheniids, etc.) 

 which may be of limited significance. Further development of fishing 

 should primarily follow the path of utilization of the fish resources of 

 the pelagic zone, particularly the sardines, mackerel, small tuna, 

 squid, etc., and also organization of fishing for bottom-dwelling fish 

 off the west coast of Australia and the east coast of Africa. 



To complete our review of the distribution of oceanic commercial 

 biologic resources, we should emphasize once more that fishing industry 

 studies of the World Ocean indicate that there is a genuine possibility 

 of significantly increasing the current catch of ocean fish and large 

 invertebrates. Catches can be increased to the greatest extent in the 

 Atlantic (by 10-12 million tons) and Pacific (by 12-14 million tons) 

 basins. The greatest portion of the probable increase (21 million 

 tons--87%) will be accounted for by inhabitants of the pelagic zone.
