WG-FSA-SAM-03/04 Mostrar menos información	WG-FSA Subgroup on Assessment Methods: Summary of current CCAMLR Assessments to end of 2002 Constable, A.J. Resumen: Each year, WG-FSA and WG-EMM undertake assessments of stocks and other parameters. The WG-FSA Subgroup on Assessment Methods (WG-FSA-SAM) is to consider the assessment methods to be used by WG-FSA in 2003. This paper aims to summarise the existing assessment process for each species considered by WG-FSA. It concludes with a suggested format for these summaries in the future.

WG-FSA-SAM-03/05 Mostrar menos información	Verification of the CMIX procedure on species with known age-length keys Gasiukov, P.S. Resumen: Calculation of age composition of density-at-length data produced during inventory surveys using the method of W.K. de la Mare (1994) is a conventional procedure in the WG-EMM and WG-FSA practice. Verification of the method was made on the materials on the Baltic cod collected in the ICES Subarea 26. Age-length keys for 1995-2001 and length frequency data obtained during the surveys Read More Presentado por: Admin Admin (Secretaría de la CCRVMA) Aprobado por: Admin Admin (Secretaría de la CCRVMA) Solicitar acceso a documento de reunión

WG-FSA-SAM-03/07 Mostrar menos información	Growth of mackerel icefish (Champsocephalus gunnari) and age-size composition of population in subarea of the South Georgia Shust, K.V. and E.N. Kuznetsova Resumen: Age, growth rate and age composition of icefish catches in subareas 48.3, 48.2, 48.1 were studied for different periods. The analysis of age composition of icefish in subarea 48.3 showed that the catches consisted mainly of individuals of 2-4 age groups, where more than 60% were represented by fish of two contiguous age groups. It was shown that in the 1980s during a number of years the Read More Presentado por: Admin Admin (Secretaría de la CCRVMA) Aprobado por: Admin Admin (Secretaría de la CCRVMA) Solicitar acceso a documento de reunión
WG-FSA-SAM-03/08 Mostrar menos información	Review of management boundaries (SSRUs) used for the assessment of D. mawsoni in Subarea 88.1 Horn, P.L. and S.M. Hanchet Resumen: This paper provides a review of the boundaries of the small scale research units used to manage the exploratory fishery for D. mawsoni in Subarea 88.1. In determining appropriate SSRU boundaries we considered the physical and geographical features of the Subarea including the impact of sea ice on fishing practices, as well as the distribution and abundance of the target and bycatch species ( Read More Presentado por: Admin Admin (Secretaría de la CCRVMA) Aprobado por: Admin Admin (Secretaría de la CCRVMA) Solicitar acceso a documento de reunión
WG-FSA-SAM-03/09 Mostrar menos información	Descriptive analysis of acoustic data collected during the 2003 exploratory fishery for toothfish in the Ross Sea O’Driscoll, R.L. and G.J. Macaulay Resumen: This report presents results from a pilot study to determine the feasibility of conducting acoustic surveys for toothfish and rattails in the Ross Sea. Acoustic data were collected using a Simrad ES60 38 kHz echosounder on the New Zealand commercial longliner FV Janas during the 2002–03 exploratory fishery. Data were recorded continuously from 28 December to 2 February 2003, then during line Read More Presentado por: Admin Admin (Secretaría de la CCRVMA) Aprobado por: Admin Admin (Secretaría de la CCRVMA) Solicitar acceso a documento de reunión
WG-FSA-SAM-03/10 Mostrar menos información	A feasibility study for stock assessment of D. mawsoni in the Ross Sea (Subares 88.1 and 88.2) using a tag and recapture experiment Sullivan, K.J., N.W.McL. Smith, J. McKenzie and S.M. Hanchet Resumen: This paper reports on a feasibility study into a tag and recapture experiment for the purpose of stock assessment of the Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea. An exploratory fishery for D. mawsoni has been operating since 1997-98. Catches have increased from ~40 t in 1997-98 to nearly 1800 t in 2002-03. Although some Patagonian toothfish (D. eleginoides) are taken in the Read More Presentado por: Admin Admin (Secretaría de la CCRVMA) Aprobado por: Admin Admin (Secretaría de la CCRVMA) Solicitar acceso a documento de reunión

WG-FSA-SAM-03/14 Mostrar menos información	The Generalised Yield Model version 5: structure, specifications and examples for validation Constable, A.J. Resumen: The Generalised Yield Model (GYM) was first developed in 1995 as a generalised form of the Krill Yield Model, which was based on the method for evaluating yield developed by Beddington & Cooke (1983). The first version incorporated options for assessing long-term annual yield according to catches set by a proportion of an estimate of pre-exploitation biomass (as in krill), a specified Read More Presentado por: Admin Admin (Secretaría de la CCRVMA) Aprobado por: Admin Admin (Secretaría de la CCRVMA) Solicitar acceso a documento de reunión

Resumen: This note describes the most recent additions to Fish Heaven and provides illustrative examples of its application as a tool for evaluating fisheries management systems. As in previous years there have been numerous small changes and additions to the functionality of the program. This note describes the large structural additions which have been made to Fish Heaven and which now allow a very Read More Presentado por: Admin Admin (Secretaría de la CCRVMA) Aprobado por: Admin Admin (Secretaría de la CCRVMA) Solicitar acceso a documento de reunión

Resumen: As part of a wider research project aimed at developing management strategies based on the current toothfish assessment methodology using the Generalised Yield Model (GYM), a Java version of the GYM has been developed. The new version has been developed directly from the specifications kindly provided by Dr Andrew Constable. Some routines have been translated from the GYM FORTRAN code into Read More Presentado por: Admin Admin (Secretaría de la CCRVMA) Aprobado por: Admin Admin (Secretaría de la CCRVMA) Solicitar acceso a documento de reunión
