The Caribbean spiny lobster, Panulirus argus (Latreille, 1804) is a highly commercial species and comprises the largest spiny lobster fishery in the world. Although populations have declined throughout its range, there is little known regarding its diseases and pathogens. The objectives of this study were to provide illustrated and standardized methods for postmortem examination, and to describe baseline gross and microscopic pathology for P. argus. From July 2017-March 2019, a postmortem examination including comprehensive histological assessment was performed on 313 fishery-caught lobsters. Epibionts and lesions observed include branchial cirriped infestation (69%), branchial encysted nemertean worm larvae (23%), tail fan necrosis (11%), skeletal muscle necrosis (7%), antennal gland calculi (6%), branchial infarction (2%), and microsporidiosis (0.6%). This report confirms the rare prevalence of microsporidiosis in P. argus and describes nemertean worm larvae in the gill. This study also reports a condition resembling excretory calcinosis in spiny lobster. The methods and data produced by this study facilitate disease diagnosis and sustainable stock management of P. argus.
加勒比刺龙虾，Panulirus argus（拉特雷尔，1804年）是一种极具商业价值的物种，也是世界上最大的刺龙虾渔业资源。尽管其分布范围内的种群数量有所下降，但关于其疾病和病原体的了解却很少。本研究的目的是提供死后检查的图示和标准化方法，并描述P. argus的基线大体和微观病理学特征。从2017年7月至2019年3月，对313只渔业捕获的龙虾进行了包括全面组织学评估的死后检查。观察到的体表附着生物和病变包括鳃蔓足类寄生虫感染（69%）、鳃部包囊内的纽形动物幼虫（23%）、尾扇坏死（11%）、骨骼肌坏死（7%）、触角腺结石（6%）、鳃梗死（2%）和微孢子虫病（0.6%）。本报告证实了微孢子虫病在P. argus中罕见的流行情况，并描述了鳃部的纽形动物幼虫。本研究还报告了一种在刺龙虾中类似排泄性钙化的病症。本研究产生的方法和数据有助于P. argus的疾病诊断和可持续种群管理。
