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