The endemic green-lipped mussel (GLM) Perna canaliculus is a key cultural and economic species for New Zealand. Unlike other cultured shellfish species, GLMs have experienced relatively few disease issues. The apparent absence of diseases in both wild and farmed GLM populations does not preclude risks from environmental changes or from the introduction of overseas mussel pathogens and parasites. Potential for disease exchange between the GLM and other mytilid species present in New Zealand has yet to be elucidated. After reviewing and discussing relevant scientific literature, we present an initial assessment of GLM vulnerability to disease threats and the potential risk pathways for mussel pathogens and parasites into New Zealand and highlight a number of challenges. These include knowledge gaps relevant to GLM susceptibility to exotic pathogens and parasites, risk pathways into New Zealand and biosecurity risk associated with domestic pathways. Considerations and findings could potentially apply to other farmed aquatic species with limited distribution range and/or low disease exposure.

新西兰养殖绿唇贻贝 Perna canaliculus 的疾病威胁：风险评估和途径分析挑战回顾

地方性绿唇贻贝 (GLM) Perna canaliculus 是新西兰重要的文化和经济物种。与其他养殖贝类物种不同，GLM 经历的疾病问题相对较少。野生和养殖的 GLM 种群明显没有疾病并不排除环境变化或海外贻贝病原体和寄生虫的引入带来的风险。GLM 与新西兰存在的其他mytilid 物种之间疾病交流的潜力尚未阐明。在审查和讨论相关科学文献后，我们对 GLM 对疾病威胁的脆弱性以及贻贝病原体和寄生虫进入新西兰的潜在风险途径进行了初步评估，并强调了一些挑战。其中包括与 GLM 对外来病原体和寄生虫的易感性相关的知识差距、进入新西兰的风险途径以及与国内途径相关的生物安全风险。考虑和发现可能适用于分布范围有限和/或疾病接触率低的其他养殖水生物种。
