Scientific and practical peer-reviewed journal

"Izvestiya TINRO" (“Transactions of the Pacific Research Institute of Fisheries and Oceanography”) is the oldest scientific periodical in the Far East. The first volume (entitled "Izvestiya TONS" in that time) was issued in 1928, when the fisheries science began developing in the Far East.

The structure of materials published in “Izvestiya TINRO” reflects the complexity of the fisheries science. They include articles on climatic, oceanographic, and hydrobiological problems and issues, biology and ecology of not only commercial aquatic organisms, but also rare indicator species; special attention is paid to the ecosystem study of biological resources, trophology, ecological capacity of biotopes and landscape zones, rational nature management, modeling of natural processes, and aquaculture. Publications on the technology of processing of raw materials from aquatic organisms, the techniques of their harvesting, and also the economic issues of fisheries’ functions hold a worthy place in “Izvestiya TINRO”.

"Izvestiya TINRO" is a rather voluminous periodical that allows publication of large articles based on significant factual materials. Formerly, the journal accepted works submitted mainly by specialists from fisheries institutes of the Far East (this was not a disadvantage, as the main resource base of the Russian fisheries is concentrated in the Far Eastern region); since the 2000s, specialists from academic institutes and higher education institutions, as well as experts from the western regions of the country have been regularly published, which has increased the proportion of publications on fundamental marine biology issues.

"Izvestiya TINRO" is well known to scientific institutions of the USA, Canada, Japan, the Republic of Korea, and other Pacific countries, whose activities are related to ocean science.

The journal is the original Russian edition.

Abstract

Complex nature of long-term dynamics is revealed for thermal parameters of the pacific salmon habitat that includes a trend to warming and cyclic changes. Changes in annual landing of pink, chum and sockeye salmon have generally positive relationship to variations of the temperature background. Period of a full cycle in the dynamics of pink, chum, sockeye, coho, and chinook salmon abundance is about 80 years, with the cycles for pink, chum and sockeye salmon synchronous to those of temperature, the cycles for chinook salmon counter-phase them, and the variations in coho salmon abundance ahead those for pink, chum and sockeye salmon in 20–25 years and ahead those for chinook salmon in ~15 years. 
In the current cycle, the highest catches of mass species, as pink, chum and sockeye salmon, have been supposedly passed in the early 2020s, so the total annual catch of pacific salmon in Russia is expected to decline to the minimum in 2050s that would be higher than the previous minimum and provide a level of ~250 . 103 t. The individual weight of pacific salmon has a tendency to decrease in the modern times of warming climate. The loss of weight in the last 70–100 years is estimated in 60 % for chinook salmon and 30–35 % for chum, sockeye and coho salmon. Dynamics of the average individual weight for pink salmon is not determined by changes in environments, but depends on abundance of feeding individuals, especially for super-strong year-classes.

Abstract

History of the Russian-Japanese cooperation in fisheries in the Far East dem- onstrates a dynamic interaction of economic, technological and geopolitical factors. Formerly Japan, possessing technological superiority, dominated in exploitation of pacific salmon that was noted in the St. Petersburg treaty in 1875 and Portsmouth treaty in 1905. Japan leaded in modernization of fishing gears and techniques, including introduction of fixed seines and drift nets, as well as in development of fish processing technology and biological studies of pacific salmon. In the Soviet period, the national state control over resources increased, but the concessions in 1920–1930s still were dependent on Japanese capital. Until the middle of the 20th century, the salmon of Russian origin dominated in annual catch of Japan (up to 86 %). 
The offshore drift-net fishing played a significant role before the ban in 2015. Modern stage in salmon fishery in the Far East is distinguished by reduction of Japanese input (2–3 % or less of the total annual catch after 2006) and increasing Russian sovereignty, including restriction on drift-net fishing and implementation of regulated quotas. However, Japan continues to lead in development of salmon farming. Russia joined to the artificial reproduction of pacific salmon and established a net of fish hatcheries in Sakhalin and Kuril Islands, although their effectiveness is controversial, in particular after lowering of the juveniles return to 1 % in 2020s. The study highlights contradictions between growing investments in aquaculture and more complicated dynamics of natural populations, as well as the need for a balance between economic efficiency and environmental sustainability. The historical analysis reveals a key role of international cooperation in shaping the resource policy: from technological borrowing to scientific collaboration. Prospects of salmon farming are related on development and integration of historical experience, deep knowledge on population biology, and adaptive management that ensure long-term conservation of biological resources in changing nature and political realities.

Abstract

Pink salmon is the leading object of salmon fishery in the Sakhalin-Kuril region. To forecast the status of its stocks, the number of juveniles migrated downstream was counted in the rivers Dagi, Malaya Khuzi, Pugachevka, Voznesenka, Ochepukha, Taranai, Kura and Kholodny Creek (tributary of the Poronai River) on the eastern coast of Sakhalin Island and in the Rybatskaya and Olya rivers on Iturup Island. These estimates reflected the year-class survival in the period from hatching to the juveniles release into marine waters. For each of these control rivers, the downstream migration index was calculated as the ratio of the number of spawners entered to the river to the number of their progeny migrated downstream. 
Based on the data on total number of pink salmon spawners and the downstream migration index for the control rivers, the number of wild juveniles migrated to the sea from all rivers was calculated, separately by areas of the local stocks. The total number of pink salmon fry migrated to the sea from the spawning grounds on the east coast of Sakhalin and Iturup Island was estimated in 2024 as 1044.5 ∙ 106 ind. and 16.1 ∙ 106 ind., respectively. In addition to these numbers of wild fry, 101.8 ∙ 106 ind. were released from salmon hatcheries of eastern Sakhalin and 28.1∙106 ind. from salmon hatcheries of Iturup Island.

Abstract

Spatial distribution of pacific herring in the Tatar Strait in spring (April-June) is considered on the data of bottom trawl surveys conducted in 2002–2022. Although the herring occur everywhere in this season, the main aggregations are located at the depths shallower of 100 m with water temperature at the bottom 0–2 °C. In spite of some interannual variations caused by temperature conditions, pre-spawning herring concentrate in rather stable areas. 
The herring spawned in the Chikhachov/de Castries Bay form the densest aggregations at the mainland and island coasts in the northern Tatar Strait, on the traverse of spawning grounds. 
The fish of the size 10–28 cm prevail there. The herring belonged to the Sakhalin-Hokkaido population distribute mainly over the shallows from Chekhov to Ilinsky. Their size is 16–30 cm but the portion of large-sized fish (> 25 cm) has increased in recent years. The herring abun- dance is the lowest in the southwestern Tatar Strait.

Abstract

Current state of the red king crab Paralithodes camtschaticus fishery at West Kamchatka is reviewed, with a focus on the northern part of the range — the Shelikhov Bay. 
Dense aggregations of the crabs with commercial size were found in the southeastern Shelikhov Bay by the trap surveys conducted in 2019–2022, so an area north of 57о40′ N was opened for commercial landing of this species in 2023, on the background of declining catches in the traditional areas south of 56о20′ N. Despite the exceptional importance of the southeastern Shelikhov Bay for preservation of the entire population of red king crab at West Kamchatka, the fishery efforts in 2023 and 2024 were mainly concentrated here. Maintaining the areas prohibited for crab fishery is substantiated, the need to develop additional measures of fishery regulation for sustainable exploitation of the red king crab resource is concluded.

Abstract

Development of the red king crab Paralithodes camtschaticus fishery in the waters of southern Primorye is overviewed. Methods of catching and processing the catch are described. Reasons for periodic reduction in density of the crab aggregations and total stock are analyzed. Dynamics of the crab fishery between the periods of its prohibition is traced since the early 20th century to the present days and duration of the banning is determined, with particular attention to the dramatic changes which led to the ban of fishery because of the stock decreasing.

Abstract

Helmet crab Telmessus cheiragonus is a potentially important commercial species dwelling in the Far Eastern Seas of Russia. Biology of its populations in the areas of Shantar Islands and West Kamchatka (northern Okhotsk Sea) is described for the first time, with particular attention to the larval cycle, growth, and sex and size structure. On the shelf of West Kamchatka, the densest aggregations are formed in June, for males and females respectively at the depths of 13–55 m (on average 21.3 ± 3.2 m) under temperature 2.8–6.5 ºC (4.8 ± 0.3 ºC) and at the depths of 16–19 m (17.3 ± 0.9 m) under temperature 4.3–5.2 ºC (4.7 ± 0.3 ºC). At Shantar Islands, the densest aggregations are observed in September at the depths of 13–23 m (18.0 ± 4.8 m) under temperature 8.3–15.5 ºС (11.9 ± 3.6 ºС). For the group growth of crabs at West Kamchatka, the maximum carapace width of females and males is estimated as 66.3 and 82.6 mm, respectively, that is less of this parameter for the males caught to the north and  northwest of Shantar Islands (86.7 mm). Moulting of helmet crab at West Kamchatka occurs in May-June, whereas the longer moult period is expected at Shantar Islands — from May to August. The mean size of sexual maturity is 40.6 mm for females and 40.3 mm for males in the population at West Kamchatka; the crab males at Shantal Islands develop slower and reach sexual maturity at the carapace width of 42.1 mm, on average.

Abstract

“Heat wave” in the Bering Sea in 2016–2019 and its consequences for oceano- graphic conditions and local populations of pacific cod Gadus macrocephalus are considered. The feeding stock of cod in the northwestern part of the sea (Russian EEZ) had fluctuated previously (1965–2012) from 25 ∙ 103 to 654 ∙ 103 t, but increased up to 1329.7 ∙ 103 t in 2017. Features of the size-age structure for the cod fed in this area in the years of “heat wave” showed a prevalence of migrants from the southeastern Bering Sea. Such active migrations of cod were conditioned by extreme heating of the water and destruction of the cold water pool at the shelf bottom caused by strengthening of warm currents that enforced the traditional migration from the south-east to the north-west and opened a new route — northward from the southeastern Bering Sea, across the shelf of Alaska to the coasts of Chukotka Peninsula or even to the Bering Strait and Chukchi Sea. Both routes coincided with the streams of the Bering Slope Current and Alaska Coastal Current, which encircled the cold water pool from two sides and destroyed this water mass. A hypothesis is proposed that the migrations were driven by northward transport of krill Thysanoessa inermis by these currents from the area of their reproduction at the continental slope accompanied by feeding migrations of their main grazer — walleye pollock. The study results allow to optimize the cod fishery in the Bering Sea for comprehensive utilization of this strongly fluctuating stock.

AQUACULTURE

Abstract

Data on distribution, stocks and biological parameters of commercial invertebrates and marine algae collected in the scientific diving survey in Aniva Bay in summer of 2024 are analyzed. Abundance and biomass of sea cucumber, gray sea urchin, and kelp laminaria in one of the aquaculture sites are evaluated and compared to the release of juveniles and planting material. Impact of aquaculture farming off the northern coast of the bay on natural populations of these species is discussed. Target volumes of commercial production were not achieved after 3 years of the species cultivation by pasturing method. Size and age composition of sea urchins in the aquaculture site did not match the parameters expected for the 4-year cycle of cultivation. No impact of pasture aquaculture on these commercial resources in the Aniva Bay is identified.
