Some 290 species of squids comprise the order Teuthida that belongs to molluscan Class Cephalopoda. Of these, about 30–40 squid have substantial commercial importance around world. Squid fisheries make a rather small contribution world landings from capture relative fish, but proportion has increased steadily over last decade, with some signs recent leveling off. The present overview describes all globe. main ecological and biological features exploited stocks, key aspects management are...
Recent studies have shown that coastal and shelf cephalopod populations increased globally over the last six decades. Although landings are dominated by squid fishery, which represents nearly 80% of worldwide catches, octopuses cuttlefishes represent ∼10% each. Total reported global production past three decades indicates a relatively steady increase in catch, almost doubling from 179,042 t 1980 to 355,239 2014. Octopus fisheries likely continue grow importance magnitude as many finfish...
Abstract Shifts in the distribution of groundfish species as oceans warm can complicate management efforts if distributions expand beyond extent existing scientific surveys, changing proportion available to any one survey each year. We developed first-ever model-based biomass estimates for three Bering Sea groundfishes (walleye pollock (Gadus chalcogrammus), Pacific cod macrocephalus), and Alaska plaice (Pleuronectes quadrituberculatus)) by combining fishery-independent bottom trawl data...
Abstract Many mobile marine taxa are changing their distributions in response to climate change. Such movements pose a challenge fisheries monitoring and management, particularly systems where climate‐adaptive ecosystem‐based management objectives emphasized. While shifts species can be discerned from long‐term fisheries‐independent data, distilling coherent patterns across space time such datasets challenging, for transboundary stocks. One approach identifying dominant of spatiotemporal...
Abstract Taxa can expand beyond historical scientific survey footprints and into new areas with different protocols as they move to track their preferred climate. In global groundfish fisheries, for example, scientists estimate population dynamics within the spatial extent of a fishery‐independent using an index known design‐based estimator. Observed changes in species distribution recent years suggest that some are moving single surveys. We must intercalibrate disparate data cover larger...
Several regression models for predicting returns of pink salmon in the Kamchatka region are presented. The data 1990–2023 were analyzed. Among available climatic and oceanological indices, most suitable using as predictors forecasting Pacific Decadal Oscillation (PDO) index, Western Cyclonic Index (WP), Arctic (AO) sea surface temperature anomaly North Pacific. Multi-dimensional «stock–recruitment» type built on identified statistical patterns, which allowed to estimate potential abundance...
Dynamics of the greenland halibut biomass in fishery districts Okhotsk Sea (or subzones) is considered. The variation East-Sakhalin subzone has a significant (p < 0.05) negative correlation with number 3+ fish other subzones, time lag 3 years (r = –0.53) and 4 –0.49), that interpreted as alternative distribution recruitment from common spawning area either to this district or ones. From hand, recruits abundance significantly positively associated 0.52, p index zonal atmosphere transfer...
Estimated length–weight relationships are presented for 11 marine fish species representing six families, found above the continental shelf and in pelagial of Okhotsk Sea. A total 13,841 specimens were caught by trawls that equipped with a 1.0 1.2 cm mesh webbing inset. The period between 1974 2015 comprised mostly spring autumn months. All highly significant (r2 ≥ .95) on log scale. None had previous estimates, two no length–length estimates FishBase.
State of the greenland halibut stock in Sea Okhotsk fishing zone is evaluated as overfished with a high probability 97.5 % by index fishable biomass, and overfishing continued 2021. This conclusion based on results double filtering posterior parameter estimates state-space generalized surplus production model JABBA (Just Another Bayesian Biomass Assessment), additional tuning new taking into account these results.

The biomass of pacific cod (Gadus macrocephalus) in the North Kuril fishing zone is estimated using a multifactorial approach, with evaluation uncertainty. For this purpose, density fish over entire restored data on obtained 2022 compared previous surveys and fishery 2021 earlier, converted to same scale, application machine learning method, as random forest multiple imputation by chained equations procedure (MICE). coefficient determination out-of-bag (test set) was > 0.8 scientific...
Statistical estimates for the exploitable stock of giant grenadier are determined, by fishing zones in Russian Far East, and interannual dynamics species biomass is considered using historical data on catches abundance. The assessments relationship with reference points dynamic models examined first time. With Bayesian approach, a priori assumptions about virgin biomass, which were made earlier results scientific surveys extrapolated to unsurveyed areas, accounted JABBA model; some errors...
Pacific saury Cololabis saira is widely distributed in the North Pacific, with commercial harvesting area between 140–172о E. Relationship of its catches distribution environmental factors investigated using daily SST data, data set multivariate ocean variational estimation system (MOVE) produced by Meteorological Research Institute (Japan) for 140–159о E (about 95 % all and 100 Russian were landed this 1994–2017), position 1 km resolution collected vessel monitoring system. Spatial sets...
Abstract Marine biota is redistributing at a rapid pace in response to climate change and shifting seascapes. While changes fish populations community structure threaten the sustainability of fisheries, our capacity adapt by tracking projecting marine species remains challenge due data discontinuities biological observations, lack availability, mismatch between real distributions. To assess extent this challenge, we review global status accessibility ongoing scientific bottom trawl surveys....
