Modelling environmental changes and effects on wild-caught species in Queensland
A better understanding of the impacts of environmental drivers on the population dynamics and abundance of key fishery species can inform flexible management decisions that pre-empt both risks of overfishing under adverse environmental conditions and opportunities for increased harvest under favourable conditions.
This investment will identify environmental variables influencing the abundance of three priority fishery species, quantify those relationships to enhance their stock assessment models, and develop a forward projection tool to inform adaptive management of each fishery. The priority fisheries being targeted are Spanner Crabs, Snapper and Pearl Perch.
This project has three key objectives:
- Find indices of association between measures of abundance and key environmental drivers;
- Use these indices to enhance the existing stock assessment model for each species; and
- Enable forecasting of environmentally driven fluctuations in targeted species’ abundance, including enhancing Management Strategy Evaluations (MSEs).
