No abstracts are to be cited without prior reference to the author.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 ...
