Marine fish are a nutritious and high-value food commodity, but many wild-capture fisheries are in decline. Thus, marine fish culture is expected to expand greatly in coming years. Management of disease is a major problem in this industry, and metazoan parasites are among the most significant disease agents in terms of economic loss and animal welfare. Current methods for controlling metazoan parasites are mostly reactionary and rely on chemical treatment. Such methods are ultimately unsustainable. Here, we summarise the life cycles of marine metazoan parasites and how this knowledge can be used for nonchemical management and control. To aid the sustainable growth of marine fish culture, we advocate for a renewed research focus on the basic life history characteristics of parasites.

海水鱼类是一种营养丰富且高价值的食品，但许多野生捕捞渔业正在减少。因此，预计未来几年海水鱼类养殖将大大扩展。疾病的管理是该行业的主要问题，就经济损失和动物福利而言，后生寄生虫是最重要的疾病媒介之一。当前控制后生动物寄生虫的方法主要是反应性的，并且依赖于化学处理。这样的方法最终是不可持续的。在这里，我们总结了海洋后生动物寄生虫的生命周期以及如何将这些知识用于非化学管理和控制。为了帮助海水鱼类养殖的可持续发展，我们提倡对寄生虫的基本生活史特征进行新的研究。
