Abstract

The article discusses the issue of the relationship between climate change and the productivity of oceanic ecosystems. The data on the course of the number of commercial populations in the productive zone of the ocean are analyzed. Comparison of data on climate fluctuations and populations of commercial fish over a period of 16 years, which will reveal the conjugation of climate fluctuations and fish productivity. On the basis of the results obtained, a model is proposed for predicting the abundance of a commercial species for several years, depending on the climate. The results obtained provide an answer to the question of whether long-term fluctuations in the abundance of commercial species are influenced by the climate or large-scale fishing.
