Neubauer, P.; Kim, K.; Langley, A. (2025). Identifying trade-offs for alternative rebuilding polices: Insights from simulations and application to tarakihi. New Zealand Fisheries Assessment Report 2025/39. 82 p.
The present study analysed different rebuilding strategies for depleted fish stocks, considering trade-offs between the recovery of fish populations and socioeconomic impacts that are particularly relevant for fishing communities. The analysis included biological and economic factors under different policies to determine minimum rebuilding times relative to generation time for fish stocks with different life histories. Simulations in this study focused on differences between management approaches and their impact on rebuilding timelines. These simulations included an analysis of risks of specific policies to lead to marked stock reductions during the rebuilding. They were also part of an idealised economic performance analysis that assessed the outcomes of different policies in relation to stock life history characteristics. The findings of this analysis were illustrated in a case study for tarakihi in the coastal waters of New Zealand’s east coast.
