9. Jack Mackerel First Australian study to collect samples of adult Jack Mackerel for DEPM. Samples may provide unbiased estimates of adult parameters (as they were collected during the day when fish were dispersed). Relatively few females with hydrated oocytes collected – this parameter is strongly correlated with female weight and has limited influence on estimates of spawning biomass. Large number of adult and egg samples from same location and time suggest that study may provide a robust estimate of the spawning biomass of Jack Mackerel off eastern Australia during January 2014. Proportion of the adult population that occurred outside this spawning area and was not spawning during this period is unknown.

10. Australian Sardine Locations where eggs of Australian Sardine were collected similar to Jack Mackerel, i.e. off north-eastern Tasmania and in Bass Strait. Likely that a significant proportion of the population of Australian Sardine off eastern Australia occurred outside this area during the sampling period. No adult Australian Sardine were collected during the present study. Adult parameters will be sourced from the literature and used for sensitivity analyses. Surveys conducted between Fraser Island and Jervis Bay during August/September 2014 will be more reflective of the total adult biomass off eastern Australia.
