A preliminary fish survey of the estuaries on the southeast coast of South Africa, Kayser's Beach - Kei Mouth: A comparative study

摘要: A basic ichthyofaunal and physico-chemical survey of estuaries on the southeast coast South Africa from Kayser’s Beach to Kei Mouth was undertaken during September October 1996. Twenty-eight (28) have been identified along this stretch coastline, these were grouped into three types: small ( 10 ha) predominantly closed estuaries, open estuaries. Multivariate analyses revealed significant differences between estuarine types both in terms their characteristics fish communities. These features consistent with those reported other parts south coast. Overall, had a lower species diversity than smaller systems moderate large systems. Although observed types, most provided important habitat for number estuarine-dependent marine as well resident species, which often recorded high numbers. Many also endemic, further emphasises importance maintaining region. This represents one few surveys little-studied section coastline. Keywords: ichthyofauna, survey, habitat,
