Abstract: In 2013, the Scientific Committee of CCAMLR could not achieve consensus on a stock ... 88.2H. As a consequence, WG-SAM requested further runs be carried out with emigration estimated in the ... model.

Revised estimates of yield for Electrona carlsbergi based on a generalised version of the CCAMLR krill yield model
Abstract: Traditional methods for estimating yield per recruit as a function of fishing mortality ... probabilities of the stock of Electrona carlsbergi becoming depleted over a 20 year period. These projections ... have been undertaken using a generalised version of the CCAMLR Krill Yield Model. This is appropriate ... because this species has a number of similar attributes to krill, including population dynamics, behaviour ...
