Contexte
The Dades trout Salmo multipunctatus Doadrio, Perea, and Yahyaoui, 2015, is a salmonid fish, which is endemic to Morocco. It lives only in the headwaters of the Dades and M’Goun rivers (<22 km stream length), on the southern slope of the High Atlas Mountains. The two remnant populations are distant (218 km) and genetically differentiated (Clavero, pers. Com). Clavero et al. (2017) evaluated the species global conservation status using the IUCN Red List Categories and Criteria, Version 3.1 (IUCN, 2012)

Présentation
The goal of this proposal is to initiate a recovery plan for the Dades trout. To achieve this goal, we identified the following objectives : i) Monitoring : a) the current species distribution using electrofishing and snorkeling along with capture-recapture, and b) the historical distribution through surveys of the popular knowledge of people about the trout, including a compilation of the personal life-long perceptions on changes in trout distribution and abundances c) the temporal patterns of trout occurrence within suitable habitat patches using GIS modeling. ii) Evaluating the seasonal fish body condition and reproductive status, the age/stage population structure, and monitoring the trout population abundance using the removal method along with snorkeling surveys. iii) monitoring stream-riparian habitat quality and quantity (temperature mapping, state of riparian vegetation), and assessing the impacts of adverse factors related to land resource use and changes in water management on the habitat quality and trout abundance using small-scale fenced vs. unfenced stream-riparian habitats experiments. iv) Restocking/reintroducing wild-caught trouts to suitable habitats with low abundance/absence of trouts, within each of the two distinct genetic stocks of M’Goun and Dades areas. v) Raising community awareness and educating schoolchildren about the importance of preserving wetland biodiversity using the Dades trout as flagship species.
