    Notizen: Synopsis The littoral environment and fish fauna of Swartvlei, an estuarine lake, was monitored for four years during which major habitat changes occurred. Initially (1979) the zone was dominated by the submerged macrophytes Potamogeton pectinatus, Chara globularis and Lamprothamnium papulosum. This plant community was replaced by filamentous algal mats during 1980 and with the disappearance of these mats in 1981 the littoral zone was transformed into a sandy habitat. There was a highly significant decline in the numbers of fishes in the littoral zone between the macrophyte and sand phases but no significant decrease in fish biomass between the two phases. Analysis of gill net catches revealed an increase in the CPUE of the family Mugilidae between the macrophyte and sand phases but a decline in the CPUE of vegetation associated species such as Monodactylus falciformis and Rhabdosargus holubi over the same period. The increase in mullet stocks during the sand phase was attributed to epipsammic micro-algal production and the input of allochthonous detritus during the 1981 floods. The three fish species diversity indices used in this study showed minor fluctuations between the habitat phases and these variations were related to changes in the equitability of distribution between the individual species within each habitat type. The numbers of fish species recorded during the macrophyte, algal mat and sand phases varied by less than 20%. The resilience of estuarine fishes to major alterations in their environment was illustrated by the fact that all fish species recorded at the beginning of 1979 were present at the end of 1982, despite major habitat and food resource changes.

    Notizen: Synopsis The ichthyofauna of southern African estuaries consists primarily of juvenile marine species that use these habitats as nursery areas. The abundance and biomass of fishes in estuarine systems are typically high but species diversity is generally low, with only a few taxa dominating the community. This relatively low species diversity is attributed to the fact that estuaries in the region are unpredictable environments which lack any degree of permanence and are dominated by mobile marine eurytopes. Although stenotopes, represented mainly by small resident species from the families Gobiidae, Clinidae and Syngnathidae, are present in southern African estuaries, little speciation appears to have occurred. A possible reason for this lack of speciation, apart from the seasonal and annual variability of the abiotic environment, is that the lifetime of individual systems is usually limited to a few thousand years. In addition, fishes utilising southern African estuaries need to remain flexible (eurytopic) in their responses to an external environment which is unlikely to become more stable in the future. Thus the lack of permanence and fluctuating nature of southern African estuaries on both a spatial and temporal scale, together with the dominance of eurytopes in these systems, does not favour the evolution of new species. A preliminary examination of the available literature indicates that a detailed review of estuarine ichthyofaunal communities on a global basis will probably mirror the trends outlined above, and reveal a domination of these dynamic ecosystems by eurytopic taxa with low speciation potential.

    Notizen: Abstract The structure and functioning of salt marsh fish communities in the overall ecology of southern African estuaries is poorly understood. This study compares the ichthyofauna associated with a salt marsh creek and eelgrass bed in an attempt to evaluate the relative importance of these habitats to fishes. Taylor's salt marsh creek and adjacent eelgrass bed in the Kariega Estuary were sampled twice per season between the winter of 1992 and the autumn of 1994. The average density and standing stock of fishes were found to be considerably higher in the eelgrass bed than in the intertidal creek. Both habitats had similar fish diversities but were dominated by different taxa, the most notable of which was the dominance of mugilids in the creek and their scarcity in the eelgrass. Taylor's intertidal creek and adjacent eelgrass beds were dominated by juvenile fish, with both habitats functioning as nursery areas for juvenile fish, albeit for totally different ichthyofaunal communities. The similar fish diversities but lower abundances in the intertidal creek compared to the eelgrass beds are in contrast to similar North American studies, and refute the hypothesis that intertidal salt marsh creeks have higher fish densities but lower diversities than eelgrass beds.
