Gelatinous plankton present a challenge to marine fish aquaculture that remains to be addressed. Shifting plankton distributions, suggested by some to be a result of factors such as climate change and overfishing, appear to be exacerbated by anthropogenic factors linked directly to aquaculture. Fish health can be negatively influenced by exposure to the cnidarian hydrozoan and scyphozoan life stages commonly referred to as “jellyfish”. Impact is particularly pronounced in gill tissue, where three key outcomes of exposure are described; direct traumatic damage, impaired function, and initiation of secondary disease. Cnidarian jellyfish demonstrated to negatively impact fish include Cyanea capillata, Aurelia aurita, and Pelagia noctiluca. Further coelenterates have also been associated with harm to fish, including sessile polyps of species such as Ectopleura larynx. An accurate picture of inshore planktic exposure densities within the coastal environments of aquaculture would aid in understanding cnidarian species of concern, and their impact upon fish health, particularly in gill disease. This information is however presently lacking. This review summarises the available literature regarding the impact of gelatinous plankton on finfish aquaculture, with a focus on cnidarian impact on fish health. Present strategies in monitoring and mitigation are presented, alongside identified critical knowledge gaps.

水母对海水网箱养殖的影响：现有知识概述和有鳍鱼健康面临的挑战

凝胶状浮游生物对海水鱼类养殖提出了有待解决的挑战。一些人认为是气候变化和过度捕捞等因素造成的浮游生物分布变化，似乎因与水产养殖直接相关的人为因素而加剧。接触通常被称为“水母”的刺胞水螅和蛔虫生命阶段会对鱼类健康产生负面影响。影响在鳃组织中尤其明显，其中描述了暴露的三个关键结果；直接的创伤性损伤、功能受损和继发性疾病的发生。被证明会对鱼类产生负面影响的刺胞水母包括 Cyanea capillata、Aurelia aurita 和 Pelagia noctiluca。更多的腔肠动物也与对鱼类的伤害有关，包括无柄息肉，如 Ectopleura larynx。准确了解沿海水产养殖环境中近海浮游生物的暴露密度将有助于了解受关注的刺胞动物及其对鱼类健康的影响，尤其是对鳃病的影响。然而，目前缺乏此信息。本综述总结了有关凝胶状浮游生物对鱼类养殖的影响的现有文献，重点关注刺胞动物对鱼类健康的影响。介绍了当前的监测和缓解策略，以及确定的关键知识差距。然而，目前缺乏此信息。本综述总结了有关凝胶状浮游生物对鱼类养殖的影响的现有文献，重点关注刺胞动物对鱼类健康的影响。介绍了当前的监测和缓解策略，以及确定的关键知识差距。然而，目前缺乏此信息。本综述总结了有关凝胶状浮游生物对鱼类养殖的影响的现有文献，重点关注刺胞动物对鱼类健康的影响。介绍了当前的监测和缓解策略，以及确定的关键知识差距。
