| Port-Reitz Creek (04°04' S, 39° 39' E) is one of the two main tidal mangrove fringed creeks found in Mombasa Island. It experiences semi-diurnal pattern of two low and two high tides every 24 hour cycle. Six stations were strategically positioned along the length of the creek and sampled for heavy metal (cadmium, copper, iron and zinc) content during July 1998. A peak of Cu and Zn (87 and 235 µg/g dry weight respectively) was observed at Station 2, which borders a steel factory and fish-processing firm. A correlation matrix showed close distribution pattern between Zn and Cu (r = 0.67) and between Fe and Cd (r = 0.62). A peak for Cd (6 µg/g dry wt) was observed at Station 3. Fluvial input in the creek was a source of Cd, Cu, Fe and Zn. Cd and Zn were of... |

| Samples were collected monthly at four fixed stations in Mida creek from May 1996 to April 1997, in order to determine the species composition, abundance and diversity of phytoplankton and zooplankton collected with 20- and 332-mm mesh size plankton nets respectively. Sampling also included measurement of salinity and temperature. Peaks in phytoplankton abundance occurred in May and January, following the long rains in April–May and the short rains in November–December. Zooplankton densities followed the phytoplankton peaks with the main peak occurring in February after the major phytoplankton bloom. Similarly, smaller peaks occurred in May and March. Copepods dominated the zooplankton forming up to 60% of total species composition. High zooplankton... |
