Pre-spawning and spawning biology of the Patagonian toothfish, Dissostichus eleginoides, around South Georgia (Subarea 48.3)
Abstract: Samples gathered from research expeditions of the longliners Medvezhy (April-June 1986 ... ) as well as Maksheevo and Mirgorod (June-July 1992) have produced new data on the biology of the ... reproductive part of the Dissostichus eleginoides population in Subarea 48.3. Analysis and synthesis of these ... data have established the bathymetric distribution patterns for different size-groups of toothfish ...

A suggested bottom trawling survey on the Ob and Lena Banks
Abstract: The paper presents calculations of water flow velocity through the codend under the ... assumption that the flow is uniform and equal on its entire surface. The calculations were made for different ... opening coefficients. The results obtained were analysed with regard to the impact of flow velocity on ... hydrodynamic forces opening the codend. These forces, different for different cod end constructions, have great ...

Development of a spatially-explicit minimum realistic model for Antarctic toothfish (Dissostichus mawsoni) and its main prey (Macrouridae and Channichthyidae) in the Ross Sea
Abstract: To explore the potential effects of the toothfish fishery on the population dynamics of ... spatially explicit model using a predator-prey suitability model for the Ross Sea Region. We model the age ... predation mortality (M2), in addition to fishing mortality (F) on all three species. The model suggests that ... the predation release caused by the fishery effect on toothfish abundance is greater than the direct ...
