Southern California has witnessed the decline of fisheries over several decades. This is of particular concern in the LA region's urban ocean where environmental impacts from increased runoff and pollution, as well as increased recreational fishing, negatively impact fish stocks, such as in the case of the spotted sand bass. Protecting ecosystems by designating marine protected areas through the California Marine Life Protected Act (MLPA) will abet some commercial and recreational fisheries management tools. Developing well-designed aquaculture projects will also help to mediate recreational and commercial fishing pressure on local fishery stocks.
