The oceanic fisheries require forecast provisions expressed mainly in terms of distribution, movements, quantities and size composition. In its turn, such forecasting requires sampling, collecting and analyzing of certain data. As usual, the more data collected, the more precise the forecast should be. There are situations, however, when traditional informative provisions predict development of the fishery more or less close to average ones, and reality turns to be hard: Norwegian spring-spawning herring in the 1960-s, north-west-African sardine in 1997, etc. Relatively simple way to avoid those difficulties one may found in the existed links of biomasses or recruitments among the different stocks. Some of them are good, some are insufficiently monitored. That mutual relations might be based on the scrutinized assessments in one of the stocks while in other one the catches only are available and other attitude is required. The 2009 yielded several evens of extreme magnitude in series of important World Fisheries: zero recruitment of blue whiting, zero presence of Antarctic krill in subarea 48.3, extremely low biomass of Chilean Jack Mackerel in the eastern part of its range (Penney, 2010), very high biomass of pink salmon in North Pacific. It is clear, that global events represent just points of the global net, the whole interrelation of which are not conceived yet. This is an attempt to trace possible synchronous changes in different stocks with the task of future predictions
