Note that we have provided a budget for the destructive sampling of periodic and equilibrium species in years one and five based on the expected level of effort required to obtain the required sample sizes and size range of species required to generate age-growth curves. This sampling will occur in addition to annual community sampling and at other locations within zone 2 (Darlington point to Carrathool) to avoid influencing annual survey results.
