Modelling Movement of Antarctic Krill (MMAK): the importance of retention, dispersal and behaviour for krill distribution
Abstract: Effective management of the Antarctic krill (Euphausia superba, hereafter krill ... ) fishery requires an understanding of the controls on the distribution and abundance of krill ... . Particularly important are the pathways and timescales of movement and retention affecting krill distribution ... at scales relevant to the fishery and predators. This paper reports the initiation of a project that ...

Comparison of estimators of effective sample size for catch-at-age and catch-at-length data using simulated data from the Dirichlet-multinomial Distribution
Abstract: The incorporation of “effective sample size” (ESS) in integrated assessments is an ... approximate but simple way of modelling the distribution of catch-at-age or catch-at-length frequencies using ... frequencies. The ESS applied within the definition of the negative log-likelihood contribution to the ... objective function in CASAL determines the implicit weight given to the commercial catch-at-age or catch-at ...
