Optimal number of sites in multi-site fisheries with fish stock dependent migrations.

open access: yesMathematical Biosciences and Engineering, 2011
We present a stock-effort dynamical model of a fishery subdivided into fishing zones. The stock corresponds to a fish population moving between these zones, on which they are harvested by fishing fleets.

Population variability under stressors is dependent on body mass growth and asymptotic body size [PDF]

open access: yesRoyal Society Open Science, 2020
The recruitment and biomass of a fish stock are influenced by their environmental conditions and anthropogenic pressures such as fishing. The variability in the environment often translates into fluctuations in recruitment, which then propagate ...

Modern state of stocks for demersal and pelagic fishes on the shelf of Olyutorsky-Navarin area

open access: yesИзвестия ТИНРО, 2021
Stocks of demersal and pelagic fish species are assessed for the bottom layer over the outer shelf and upper continental slope between Cape Olyutorsky and Cape Navarin (northwestern Bering Sea) on the data of bottom trawl survey conducted aboard RV ...

Modern specialized fishery of sea fish in the western Bering Sea

open access: yesИзвестия ТИНРО, 2021
The shelf and continental slope of the western Bering Sea, being among the most productive areas of the Far-Eastern Seas of Russia, became exploited by commercial fishery half a century ago, after introduction of 200-mile exclusive economic zones in 1977

An approach to assess exploited fish stocks compliant to the requirements of the Marine Strategy Framework Directive (MSFD) including criterion D3C3

open access: yesEcological Indicators, 2023
The Marine Strategy Framework Directive (MSFD) complements European fish stock assessments under the Common Fisheries Policy (CFP). CFP assessments separately assess fishing mortality (F) and spawning stock biomass (SSB).

Fish harvesting strategies with allee effect [PDF]

open access: yesITM Web of Conferences, 2020
Fish harvesting is important for nutritious food availability in human diet. In this manuscript, a simple fish harvesting model is developed using logistic growth along with allee effect.

Analytical materials on commercial use of some rivers in the Shelikhov Bay in modern conditions

open access: yesИзвестия ТИНРО, 2023
Commercial capability of the certain rivers in Shelikhov Bay (Okhotsk Sea) is analyzed for modern conditions. The fishery load on stocks of pacific salmon and char in these rivers is estimated.

Bathymetric groupings of demersal fishes on the slope and outer shelf at the oceanic side of southern Kuril Islands in spring season

open access: yesИзвестия ТИНРО, 2014
Abundance and species composition are investigated for demersal fish at the oceanic side of southern Kuril Islands on the data of the bottom trawl survey in the depth range 100-1400 m conducted in the spring of 2009 (for the first time at the continental
