Abstract: According to monitoring data in 2021, per capita salmon consumption per year was 2.73 kg, which is more than shower consumption of pollock, cod, mackerel. The authors analyzed the effect of water surface temperature at the test site located in the north-western part of the Pacific Ocean on the catches of Pacific salmon in 1998-2021. Quite close correlations between the catches of Pacific salmon and the water temperature on the surface were revealed (r=0.65). It was noted that the variability of water temperature has a closer relationship with salmon catches in odd years (r=0.81) compared to even years (r=0.41). In addition, it was found that during periods of maximum solar activity, salmon catches decreased, while during periods of their minimum values, on the contrary, they increased. According to the forecast, during the period of the maximum of the next solar cycle, salmon catches will decrease to the level of 200-250 thousand tons; however, their growth will be noted in the future. The influence of water surface temperature and solar activity on salmon catches is clearly traced, while the pricing factors for this type of fish are more diverse.
