The Imraguen are former tributaries (Mauritanians say "slaves") of the Mauritanian desert families who owned camel herds. They are sent to hunt in Banc d'Arguin. Until the beginning of the 20th century, they were mainly nomads and moved along the beach in camps. They left it for several months, and when there were no more mules, they returned with the fish the women had dried. There they became shepherds. Over the course of a year, they combined two completely separate activities. Under the social division of labor, men engage in fishing and women, who account for about half, are devoted exclusively to processing activities. Many people in Banc d'Arguin, especially therapist women, suffer from a lack of resources available to them for their activities. They also claim there is no oversight. The industrial fishing along the Mauritanian coast threatens this way of life and many Imraguayans live in poverty.

The current population of Emraguen includes about one thousand three hundred (1,300) people distributed over five villages (Agadir, Iwik, Noamghar, Raqiba, Tikot) established by different tribes. Each existing tribe sought in this space to acquire its own plot of land to later declare itself as the master of the place. This has contributed to the official establishment of the Banc d'Arguin National Park (PNBA). The fish products mainly come from yellow mullet. For Imraguen processors, now they can process the products, and sell them in urban centers. Therefore, the situation has improved. In Imraguen, fish processing takes many forms and can be classified into four categories: Tischtar, Likhlie, Fish Oil and Bottarga. Seasonal activity runs from November to February and thus corresponds to the period of mullet abundance in the coastal zone of the PNBA.

The GOWAMER project (related to the West African Marine Ecoregion) with the cooperation of the Banc d'Arguin National Park (PNBA) aims to reduce poverty and enhance food security for coastal communities in Mauritania, the Imraguen, through the study of population perception, in order to better understand expectations and analyze the interactions between local people and development practices through the implementation of development projects under the motto of "Participatory Approach". By analyzing the current status of this activity in the PNBA (the villages located inside and outside the park), and knowing the social and anthropological situation of the people of Banc d'Arguin National Park (PNBA), the GOWAMER project aims to find appropriate solutions that will last even after the completion of the project.

The GOWAMER project has trained the Imraguens in good handling practices. In general, these interventions and accumulated technical knowledge forced Imragen hunters and processors out of their technical, economic and social isolation. Today the activities of production and marketing of Imraguen fishing products are for profit and represent a weight in the local economy. There has also been a significant evolution with the improvement of transport services to market fish to the big cities (Nouadhibou, Nouakchott). For example, one kg of bottarga varies in the park between 800 and 1200 MRU. It is sold in Nouakchott at 2000 MRU minimum. The selling price of fresh mullet eggs in the Park is estimated at 330,000 MRU (i.e. €8,500). The income of Imraguen women processors is estimated between 3,000 and 5,000 MRU per fishing season.
