All fish stocks are subject to some level of environmentally driven change in productivity, primarily recruitment, but also growth. Current harvest strategies assume either a long-term equilibrium or some average, associated target and limit reference points to determine population size and catch limits. In a number of fisheries these approaches are justifiable, but in others the use of equilibrium-based reference points and harvest strategies do not correctly reflect the natural dynamics of stocks where environmentally driven productivity changes occur. This can lead to sub-optimal management, either over-utilising a reduced productivity stock or under-utilising an increased productivity stock. There have been a number of ad hoc efforts to conduct population projections using recent recruitment, rather than average (stock-recruit relationship) for the purposes of recommending multi-year TACs. In this project, these initiatives will be formalised and explored to provide a rigorous basis for determining future recruitment scenarios for use in population projections for a range of fisheries that are subject to changes in productivity from environmental variables.
