Fish Diversity and Abundance of Lake Tanganyika: Comparison between Protected Area (Mahale Mountains National Park) and Unprotected Areas

Table 1

Environmental parameters mean (±SD) of the sampled sites in Lake Tanganyika during May to June 2008 survey. Sites S1, S2, S11, and S12 are within unprotected areas and sites S3–S10 are within the protected area (Mahale Mountains National Park).
