A system-of-equations approach to modeling age structured fish populations: the case of Alaskan red king crab, Paralithodes camtschaticus
Abstract: This paper presents a simultaneous system-of-equations approach to modeling age ... properties of a delay-difference model. The framework shares a common spawner-recruit function across age ... variable, lessening the effect of measurement errors in estimation. The dynamic features of the underlying ... effect of measurement error and improve overall estimation efficiency. A seemingly unrelated regression ...

Review of Dissostichus spp. fishery in the adjacent seas of three Antarctic sectors in 2003–2010
of the Antarctic toothfish is commercially viable not only for countries which are close to the ... the Pacific and Indian sectors of the Antarctic. According to lack of data on the Antarctic toothfish ... estimation of toothfish stock and TAC values in all high-latitude Antarctic seas is necessary. From data ... available we suggest that factual stock values of the Antarctic toothfish are considerably underestimated in ...

Abundance, size and maturity of krill (Euphausia superba) in the krill fishing ground of Subarea 48.1 during 1990/91 austral summer
north of the South Shetland Islands from 18 January to 3 February 1991. Distinct offshore-inshore ... heterogeneities in abundance and maturity of krill were observed. The survey region was divided into four zones ... ; oceanic, slope frontal, neritic and nearshore zones. The mean density of krill was low in the oceanic zone ...
