Fisheries biology and ecology has evolved over the last 50 years. It is less confident in its stock assessment models and this is reflected in attempts to include the impact of uncertainty in available data and fishery descriptions. Natural resource mangement is no longer about determining the maximum sustainable yield, but is rather about providing advice to managers that explicitly characterises the opportunities and risks of alternative management
actions. Fish stocks are not amorphous continuous units, but are rather aggregated spatially, living as semi-disconnected groups of populations across arrays of habitats. Explicit spatial management of natural resources is becoming more common and will become more important
in the future . Ecosystem- based fishery management remains an illusory aim that is being implemented as single species management with attention being paid to bycatch and impacts of fishing gear on habitats. Fisheries ecology is a field in which there is still a great deal of
research needed to enable more effective management of important natural resources.
