The study aimed to determine the distribution and relative abundance of freshwater fish in the Wilderness National Park. Fish assemblages in the Touw and Duiwe rivers were sampled in 1997 and 1998, with a total of 327 fish from nine species recorded. Indigenous species included two freshwater species (Pseudobarbus afer, Sandelia capensis), two catadromous species (Anguilla mossambicus, Myxus capensis), and two estuarine species (Monodactylusfalciformis, Caffrogobius multifasciatus). Three of the nine recorded species were alien (Micropterus dolomieu, Micropterus salmoides, Gambusia affinis), with the Micropterus spp., in particular, likely to have a substantial negative influence on indigenous species. A further one indigenous species, two translocated indigenous species, and five estuarine species could potentially be recorded in these rivers. River catchment management actions to restore perennial flow to the Duiwe River, to prevent the attenuation of floods, and to prevent further establishment and spread of alien and translocated biota are required to conserve indigenous fish assemblages.

Feasibility of monitoring of the littoral fish assemblages at the reserved water areas (Karadag Nature Reserve, Crimea) by methods of visual estimation and video recording involving data of fish catch statistics of fishing companies and recreational fishermen providing fishing in the waters adjacent to the reserved aquatory is discussed. At the water area of the reserve 18 species (35%) were identified exclusively by visual recording and video recording methods, 13 more species were identified by the mentioned contactless methods and simultaneously as a result of the analysis of information from recreational fishermen and fish catch statistics. As a result, 31 species of fish (or 61 % of the identified species) were identified visually or by video recording. The contactless methods were detected mostly sedentary (15) and nomad (11) species. Migratory species in the majority (9 species vs. 6) were identified only as a result of the analysis of information from recreational fishermen and fish catch statistics.

Abstract A continuous gradient of physical and biological processes exists within a river system from headwaters to mouth, according to the River Continuum Concept. In this study, the River Continuum Concept was used to compare patterns in fish assemblages and diversity trends to Remane predictions. The findings show that species diversity is low near the estuary's mouth and increases upstream. While the presence of several marine and estuarine species increased species diversity upstream in the river due to the dominance of freshwater fishes, it decreased downstream due to the presence of several marine and estuarine species. These patterns are consistent with the biogeographical trend of decreasing species richness along the South African coast from east to west. Based on the findings of this study, the River Continuum Concept ignores plasticity, which is evident in species that use transitional waters. As a result, the concept is insufficiently valid for the Orange River Estuarine Continuum, and a new concept known as the “River-Estuarine Continuum” has been proposed.
