The fishery of the area has been variable over the years. Bulman attempts to capture the trophic flows and biomasses during the late 1980s. At this time, the foreign fishery had reduced considerably following closures and the domestic fisheries were expanding. Fifteen years of catch and effort data were used to tune the model, i.e., annual fishing effort data were input in order to try to recreate the actual changes in the system caused by fishing. {"type": "Polygon", "coordinates": [[[20.0, -70.0], [127.0, -70.0], [127.0, 28.0], [20.0, 28.0], [20.0, -70.0]]]} 20.0 127.0 -70.0 28.0
