英文摘要	Basic life history information can be useful for informing the management of protected species such as the Pahrump Poolfish Empetrichthys latos, a goodeid (Cyprinodontiformes) that is endemic to the Mojave Desert in southern Nevada, USA, and the last surviving remnant of Empetrichthys. Critically endangered and extirpated from its native range, Pahrump Poolfish has been managed among constructed refuge habitats since 1971. To better understand sex-specific age demographics, we used thin-sectioned otoliths to age 121 Pahrump Poolfish from one population, collected in June 2017. These samples suggested a maximum age of 10 years for females and 7 years for males, with a substantial portion of all fish greater than 4 years old. This is more than twice the previously reported maximum age for this species. We report on the inadequacy of reading whole otoliths, opercula, and scales for age analysis of this species. Based on thin-sectioned otoliths, we also model growth in length as a function of age among individuals. We found significant sexual dimorphism across this fish's ontogeny, which has implications for selecting an appropriate sex ratio for founding populations.
