On the catchability of bottom trawl in relation to icefish (C. gunnari)
Abstract: Analysis of Russia HAK-4M trawl catchabilities has been made in the paper. This trawl have been used when icefish bottom surveying. An analysis of total catchability and a differential one (that is catchability in relation to fish of different length) has been realized by models of

Variants of the ASPM assessment of the toothfish (Dissostichus eleginoides) resource in the Prince Edward Islands vicinity which attempt to reconcile CPUE and catch-at-length data
Abstract: Two variants of the ASPM assessment of the Prince Edward Islands toothfish resource are examined. One allows for the possibility of changes in somatic growth rate in response to increased food availability as resource abundance drops. The other permits annual fluctuations about a

Estimating toothfish biomass in Subarea 48.3 using local depletions
Abstract: We investigated local depletions of toothfish under concentrated fishing effort as a means of estimating toothfish density at South Georgia. Over the four years 2000-2003, we found 25 areas of 12’ by 12’ where there had been forty or more hauls in any particular year. There were 62

Considerations on the design and evaluation of surveys for estimating recruitment of Patagonian toothfish (Dissostichus eleginoides) with preliminary outcomes for the Heard Island plateau region (Division 58.5.2)
Abstract: Assessments of long-term sustainable yield using the Generalised Yield Model and the setting of total allowable catches (TAC) for Patagonian Toothfish, Dissostichus eleginoides, for the Heard Island Plateau region (Division 58.5.2) are based on data obtained from annual random stratified

Approaches to monitoring and assessing toothfish in new and exploratory fisheries, with particular reference to Subarea 88.1
Abstract: This report presents results from a desktop study to consider approaches to monitoring and assessing toothfish in New and Exploratory fisheries. We review standardised CPUE analysis, quantitative research longline surveys, experimental manipulation of fishing effort, tagging programmes,

Application of the bootstrap-method in assessment of target strength regression parameters on the basis of in situ measurements
Abstract: Target strength (TS) as a function of fish length (L) must be known to estimate fish density in acoustic survey. This TS-length function may be estimated by comparing in situ acoustic measurements with the fish size composition from trawl catches and should be accompanied with accuracy
