Droughts are likely to increase in frequency and severity with climate change, modifying the economic viability of inshore fisheries in regions of hydrological extreme. Variation in the revenue and profit associated with different mixtures of fishing methods between non-drought and drought conditions was examined for commercial fishing businesses in three estuarine and coastal systems in eastern Australia...
Commercial catch-per-unit-effort (CPUE) data from nine estuaries were related to hydrological variation in eastern Australia. Relationships between drought declaration, rainfall, freshwater flow and fisheries catch rates were assessed from 1997 to 2007. Estuaries varied from 0.5 to 2.0×10 6 ML of mean freshwater inflow per annum. Monthly CPUE data from gillnetting were used to infer the abundance...
