Physico-chemistry characterization and zooplankton specific diversity of two fishponds in Yaoundé (Cameroon, Central Africa)

Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 2

Abstract

The specific composition and structure of zooplankton in two fish ponds (one being natural E1 and the other man-made E2) in Simbock, Yaoundé, was studied in relation to some physico-chemical variables, between April and December 2007. Physico-chemical parameters were measured according to the techniques described by APHA (1985). Biological analysis was done, using specific identification keys. Sixty nine zooplankton species, mostly coastal, periphytic and cosmopolitan, were identified, rotifers being the most abundant (71%). Eight of these species were recorded for the first time in Cameroon: the Copepod Diaptomus sp., the Rotifer Macrochaetus sp. and the Cladocerans Leydigia australia, Pleuroxus chappuini, Daphnia magna, Chydorus baroisi, Guernella monodi, Moinodaphnia macleayi. Zooplankton abundance was low (less than 400 ind. / L) throughout the study. Thus the water bodies showed limited food resources. Cladocerans density was high before the stoking (at the beginning of the study) and became very low one month after. This group is probably a preferred food for fry and juvenile fish. Index values of Shannon and Weaver together with Evenness of Pielou demonstrated that these environments are highly diverse and reveals a more or less equal distribution between species. Biocenotic and biotic parameters confirmed that these waters are oligotrophic (E1) and oligomesotrophic (E2); therefore they can’t fully meet the expectations of the farmers. It is recommended that farmers should have a basic understanding of the biology and ecology of the water bodies used for fish production.
