保育: Pseudotropheus lucerna 由国际自然保护联盟（IUCN）在濒危物种红色名录中为自然保育而进行了评估 evaluated (LC) 无危（Least Concern） (2018). The shallow intermediate habitat is very common along the lake's shores and P. lucerna is probably present in large numbers. The rocks of the habitat prevent it from being captured by beach seines and the species is thus not vulnerable to over-fishing. Even with a possible deterioration of shallow habitats by increased agricultural runoffs P. lucerna is accustomed to living in sediment-rich environments and will probably also cope with such types of threats.
