Abstract In this study, we develop a dynamic Inverse Almost Ideal Demand System model to derive own- and cross-price flexibilities for wild-caught fish, Australian farmed salmon and imports of fresh and frozen fish. We find that the growth of fresh fish imports and Australian farmed salmon production have both individually had a significant negative impact on the prices received for Australian wild-caught species, particularly the lower valued species. Continued growth in imports and the farmed salmon sector may negatively impact prices and hence profitability in wild-caught fisheries in Australia in the future.

进口和养殖鲑鱼的变化对澳大利亚野生鱼类价格的影响

摘要 在这项研究中，我们开发了一个动态逆几乎理想需求系统模型，以得出野生捕捞鱼、澳大利亚养殖鲑鱼以及新鲜和冷冻鱼进口的自有价格和交叉价格灵活性。我们发现鲜鱼进口和澳大利亚养殖鲑鱼产量的增长都对澳大利亚野生捕捞物种的价格产生了显着的负面影响，尤其是价值较低的物种。进口和养殖鲑鱼部门的持续增长可能会对价格产生负面影响，从而影响未来澳大利亚野生捕捞渔业的盈利能力。
