Trophic Relationships of Coastal and Estuarine Ecosystems
Other Publication ResearchOnline@JCUAbstract
[Extract] Food has been one of the major drivers of human interaction with coastal and estuarine ecosystems, and this has impelled much of the study of these systems. In its initial phase, greater understanding would have brought direct payoffs in the form of greater catches and, now, greater understanding is necessary to not just to counter past mistakes (such as overexploitation, habitat loss, and pollution) but also future pressures (such as climate change). The key change has been in the recognition that the oceans were not an infinite resource, and that sustainability of the resources was the key not only regarding commercial returns, but also in terms of socioeconomic stability of the human populations. As a result, scientific investigations in the cause of exploitation of the fisheries' resources, for example, has progressed from a simple goal of maximizing the catches through one where long-term yields (e.g., MSY or maximum sustainable yield) of single species were the required model outputs to the present situation in which the sustainability of the ecosystem itself is the overriding goal.
