Age and growth rates of the critically endangered fish Garra ghorensis can inform their conservation management

---

1. Information on the life-history traits of threatened fishes can inform their conservation as they can indicate resilience to environmental change and vulnerability to extirpation and extinction. Garra ghorensis, a small (2 years. Variability in length at age was apparent within sites, suggesting protracted spawning. Females were significantly larger than males.
4. Growth rates and lifespans of G. ghorensis were highest at the most disturbed site (habitat loss and the presence of the invasive Oreochromis aureus). This growth plasticity in response to slower flows and deeper water suggests G. ghorensis has some resilience to environmental disturbances and suggests that their conservation management might not have to return their habitats to pristine conditions to avoid impacts on their lifespan and growth parameters. It also shows that further work is needed to identify the issues that are affecting the persistence of their populations.

KEY WORDS: IUCN Red List; habitat loss; von Bertalanffy growth model; modal progression analysis; conservation
