Russian Pacific Salmon: What Catches May We Expect?
Abstract
Some parameters of abundance dynamics for the Pacific salmon species breeding in Russian waters are clarified and their possible catch on a medium-term scale estimated. The average annual catch for the 1907–2022 period was approximately 250 000 t. A complete cycle from the minimum values on the curves of one low-abundance period to the respective parameters of another period took approximately 72 years; from the relative maxima of one high-abundance period to another took 75 years. The duration of the high-abundance period was almost 35 years; the low-abundance period was almost 40 years. Taking various uncertainties into account, the periods of high and low abundance were approximately equivalent and remained within a relatively stable range from 35 to 40 years. Most of the high-catch seasons occurred in the odd-numbered years. Dominants usually changed during the periods of increase in Pacific salmon abundance. The average annual catches are expected to be higher than 250 000 t in the second half of the 2020s and the first half of the 2030s. Catch sizes are unlikely to be lower than 200 000 t even in the least productive years. In the final part of the high-abundance period, the raw material base of the Russian salmon fishery does not provide conditions for profitable operations at most of the fishing sites allotted for commercial harvesting.
期刊介绍:
The Russian Journal of Marine Biology was founded in 1975 by Alexey V. Zhirmunsky, member of the Russian Academy of Sciences. The Russian Journal of Marine Biology covers a wide range of research and some applied aspects of marine biology as a synthetic science related to various fields of study on marine biota and environment. It presents fundamental research on biological processes at molecular, cellular, organismal, and populational levels in marine organisms. Consideration is given to marine objects as models in life sciences. The journal also publishes papers dedicated to events in Russian and international marine biological science and the history of biology.
