Assessment of Community Indigenous Knowledge on Traditional Use of Arthrospira, Spirulina Species

Arthrospira/Spirulina has a high content of proteins, pigments, essential fatty acids, vitamins and minerals. In Ethiopia Lake Aranguade (HoraHadho) and Chitu and also in Kenya Lake simbi and nakuru are dominated (almost unialgal population) by Arthrospira. This microalga is the major food source for monkeys and the vast flocks of lesser flamingo in the lakes. The objective of the present study was, therefore, to assess and document community indigenous knowledge on traditional use of Arthrospira species in Lake Arenguade Ethiopia. Data was collected using structured and semi-structured questionnaire, personal interview, focus group discussion. Questionnaires were designed to collect information across 22 group informants (111 informants) who involved in the study from Gerbichakebele. From all study participants 98 (88.3%) were female and 13(11.7%) were male. Most of the respondents reported that Spirulina (thick algal mat) covered the lake during spring season, when there is cloudy air condition. All study participants said that no needs Spirulina for food but, monkeys are the only animal that uses Spirulina for food. Cattle also use the water for drinking during shortage of greases. All of the respondents reported that Spirulina is important for traditional medicines to prevent lesion and skin scabies for animals and humans. All respondents reported that uses Spirulina for house painting and wash their cloth. As a conclusion Arthrospira have been used for manypurposes by the farmers live around the lake for many years until now. All citizens have a responsibility to participate in the restoration of the lake as well as utilization of the resource wisely.
