Review of the use of survey data and length-at-age models in the assessment of Dissostichus eleginoides in the vicinity of Heard Island and McDonald Islands (Division 58.5.2)
Abstract: This paper reviews the allocation of historical survey data to the new strata and the ... implications of this review to estimating the abundance of juvenile fish using CMIX. In addition, the paper ... could affect the estimates of juvenile abundance. Model estimates were best incorporating the ... reassignment of hauls and the latest estimates of length at age, but quality of model fit and estimates of ...
