(Final report added 11 November 2009)
Supplementary report added September 2009
Summary
The period covered in this report is from 2 December 2008 when the first team arrived on Enderby Island through to the departure of the second team from the Island on 16 February 2009.
This work continues annual surveys of the Auckland Island breeding sites of the New Zealand sea lions (Phocarctos hookeri). The project’s objectives were to collect data to allow quantification and estimation of:
i) NZ sea lion pup production;
ii) survival of previously marked NZ sea lions;
iii) reproduction by known age female NZ sea lions;
iv) tag pups produced during the 2008/09 breeding season;
v) maintain and update the NZ sea lion database;
vi) to characterise at-sea distribution of poorly known age and sex classes of NZ sea lions and;
vii) Analyse at-sea distribution data in a fisheries context.
