项目摘要

The environment is changing as increasing carbon dioxide is released into the atmosphere from the burning of fossil fuels. The atmosphere is warming and the oceans are absorbing more carbon dioxide and becoming more acidic. This reduction in ocean pH is known as ocean acidification. Calcium carbonate is abundant in the oceans as organisms such as shellfish produce protective shell structures. The amount of carbonate available in the oceans under ocean acidification will be reduced, limiting the ability of organisms to produce protective shells. This project will investigate the influence of ocean acidification and warming on the ability of three shellfish species to produce protective shells. Commercially available shellfish will be cultured under future ocean acidification and warming conditions in a laboratory. Shells will be tested for physical and material properties to understand the vulnerability of shells to fracture under changing environments and predation. This project will determine how molluscs produce their calcium carbonate shells, identifying the carbon source and route for shell production under changing climates. This knowledge will enable accurate predictions of the vulnerability of aquaculture to ocean acidification and warming. Feeding experiments and harvesting protocols will be developed to alleviate potential damage to shells during aquaculture for a more resilient, sustainable and more economical shellfish culture.

由于化石燃料的燃烧释放到大气中，环境正在变化。大气正在变暖，海洋吸收了更多的二氧化碳并变得越来越酸。海洋pH的减少被称为海洋酸化。海洋中碳酸钙丰富，因为贝类等生物会产生保护性壳结构。海洋酸化下可在海洋中可用的碳酸盐量将减少，从而限制了生物产生保护性壳的能力。该项目将研究海洋酸化和变暖对三种贝类生产保护性壳的能力的影响。在实验室的未来海洋酸化和变暖条件下，将培养市售的贝类。将测试壳的物理和材料特性，以了解在不断变化的环境和捕食下壳体断裂的脆弱性。该项目将确定软体动物如何生产其碳酸钙壳，从而在变化的气候下识别碳源和壳产量的路线。这些知识将能够准确预测水产养殖对海洋酸化和变暖的脆弱性。将开发喂养实验和收获方案，以减轻水产养殖过程中对贝壳的潜在损害，从而获得更具弹性，可持续性和更经济的贝类培养物。
