1. Fatty acid analysis to infer diet of Antarctic toothfish caught in February 2012 in the southern Ross Sea

   south of SSRUs 881.J and 881.L in the southern Ross Sea, their lipid composition was determined and ... compared tolipid profiles of fish and invertebrate species taken as bycatch in the fishery or collected ... from stomachs of toothfish. Stable carbon and nitrogen isotope ratios were also determined to further ... identify feeding relationships between these species. The aim of this study was to establish the ...

2. Fish Heaven: a Monte Carlo, spatially explicit single species fishery model for the testing of parameter estimation methods

   basic features of standard fish modeling with a number of optional extras. It was designed within an ... object oriented framework to allow for the possible extension in a number of directions. In particular it ... was designed with the view of testing the efficacy of different statistical sampling regimes given ... various plausible spatial structures of fish stock. The model has a simple age and space structured ...

3. A risk management framework for avoiding significant adverse impacts of bottom fishing gear on Vulnerable Marine Ecosystems

   adverse impacts of bottom fishing gear on Vulnerable Marine Ecosystems (VMEs) are avoided. Due to the high ... levels of uncertainty surrounding both the evidence of VME presence and the consequences of interaction ... with different types of gear, a risk management framework is proposed, similar to that which has been ... used successfully by IMAF to minimise the effects of longline fishing mortality on seabirds. The aim of ...

4. On acceptable scattering of longlines geo-referencing in the toothfish fishery in the CAMLR Convention Area

   Abstract:  The issues of longlines geo-referencing during the exploratory fisheries of the ... toothfish in the Convention Area are discussed. Cases of differences in the coordinates of settings and ... haulings are considered. The estimation of the maximum possible variation of the coordinates in the depths ... range of 550-3000 m was performed. It is shown that the differences of coordinates of settings and ...

5. An alternative method for estimating the level of illegal fishing using simulated scaling methods on detected effort

   this new method are similar to those of the Agnew and Kirkwood (2005) method, and this suggests that ... the current method is adequate under circumstances of low evasion and when good knowledge exists that ... zero observations reflect zero illegal fishing. The new method performs better in the case of zero ... detections and can potentially better handle the evasion of detection by illegal activity. Both the new and ...

The new method performs better in the case of zero detections and ... can potentially better handle the evasion of detection by illegal activity. Both the new and the ... current method suffer from the type of observations method used, which directly affects the system. This ...

   Abstract:  The horizontal and vertical distributions of larvae and reproductive timing of ... . Occurrences of larvae of Euphausia frigida and E. triacantha were confined to the northern oceanic area where ... distribution further southward to the area where cooler Lower Circumpolar Deep Water prevailed. Larvae of ... juvenile or adult stages. Eggs and larvae of E. superba occurred with gravid females along the slope, but ...

9. 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 ...

10. An attempt to derive a composite index of abundance from acoustic surveys and fishery data

    Abstract:  Maps of krill (Euphausia superba) density derived from acoustic survey data and the ... distribution of fishing effort in the Chilean krill fishery indicate an area of high krill density wrapping ... around the northwestern end of Elephant Island during the austral summer of 1992. In this area, the ... distribution of catch-per-fishing-time and krill density (measured acoustically) show similar forms. Search ...
