These fish are listed as Near Threatened due to their endemic status and habitat loss. As you can see the fish are adapted to decent flows and need clear good quality water for their food to develop.

The Kraai River in the Eastern Cape of South Africa forms part of the upper Orange River system. The watercourse is a fast flowing mountain watercourse with steep gradients, cobbled ...substrates and rapids.
In December when the water heats up, the runs of the Kraai River are habitat for thousands of juvenile Labeo capensis and Labeobarbus aeneus. I hope to return to this river to find some of the adult Labeobarbus.
The sheer abundance of juvenile fish observed in this habitat provides some indication of the importance of the watercourse for downstream fisheries.

The Wit River (Witrivier) is a headwater tributary of the Grootrivier in the Gamtoos River system. The river supports an important agricultural region in the Eastern Cape, South Africa.
The river ...is situated within the Cape Fold Freshwater Ecoregion with typical cape flora and fauna associated with it. Pseudobarbus swartzi a Vulnerable listed species (IUCN, 2022) was well distributed in the river during December 2020 and 2021. The fish appeared to be breeding throughout the river becoming concentrated in deep pools below waterfalls high up in the catchment. Sandelia cf. capensis, another typical cape species was also observed. Enteromius pallidus (Smith, 1841) which occur between the Krom and Great Fish River systems were found in breeding condition in December 2021.
The Cape Fold endemic Chlorolestes umbratus (White Malachite) and Pseudagrion furcigerum (Palmiet Sprite) were found amongst other more widespread Odonate species. The rivers were lined with dense stands of marginal vegetation such as Gunnera perpensa, Blechnum spp. and stands of the endemic Aponogeton distachyos in the pools. The woody riparian vegetation consists of tall Outeniqua Yellowwood's which provided habitat to the elusive Narina Trogon. We left camera traps in the riparian habitats and a found Genet cat, which are commonly found in riparian habitat.
It is always difficult to present all the findings, but hopefully I will put the detailed findings on the website soon.Show More

Bonjour à toutes et à tous,
cette fois, je vous propose de découvrir le Biotope d'une espèce de poisson un peu originale en aquariophilie : le poisson Arc-en-ciel de Madagascar - Bedotia madagascariensis
Dans cette vidéo, on va notamment partir observer l'habitat dans lequel ils vivent à l’état sauvage, pour mieux comprendre les conditions qu'il va falloir recréer pour l'élever en aquarium.
J’espère que vous allez passer un bon moment.
A bientôt.

This is a video to show the various habitats and some basic results of the fish community assessment, as well as a behind the scenes type video showing what type of work goes into the survey although only short clips are shown. There is no sound in this video, hopefully we will get the background (environmental) sounds in the next survey!
An overall low abundance (biomass) of fish species during the survey. However, plenty of rheophilic species (flowing water) were observed such as Amphilius natalensis and Chiloglanis anoterus and the listed Chiloglanis emarginatus.
In small pools and floodplains we did find Clarias gariepinus, Tilapia sparrmanii and Coptodon rendalli. Unfortunately we also found plenty Micropterus salmoides too.
Overall, a diverse and sensitive group of aquatic biota were observed in the river system.

Glowing redfins swarming among the cobbles, a speckled galaxias suspended weightless in the bubble line and a pack mottled kurpers lurking silently in the shadows. Wiley eels grin in their ...cavernous lairs as night sets in and their hunt begins. Large cyprinids like the Clanwilliam sandfish migrate great distances upstream to their rocky spawning grounds as the winter floods subside. A hundred years ago our fynbos rivers pulsed with fish life, but sadly those days are now long gone.
Low-lying reaches have been degraded by human activities like agriculture, and fish populations decimated by predatory alien fish. Today, our fynbos rivers are largely devoid of native fish species - a depressing realization given that the majority of these species occur nowhere else on the planet. Our sensitive fynbos fishes are backed into a corner like a wounded boxer losing a fight. They have retracted deep into isolated mountain tributaries which are now their last outposts within vast networks of uninhabitable riverscapes. Nearly all of these species have made their way into the pages of the IUCN’s red data list http://www.iucnredlist.org/, and some are now so rare and isolated that they are literally swimming on the edge of extinction. Again, a depressing prospect, but there may yet be light at the end of this dark tunnel.
In 2012/13, an ambitious conservation project conducted in the Rondegat River in the Cedarberg demonstrated, under the disapproving eyes of its many sceptics, that sections of river can be rehabilitated and cleansed of alien fish. The project was spearheaded by the local conservation authority CapeNature, and monitoring by the South African Institute for Aquatic Biodiversity (SAIAB) revealed rapid recolonization by native fishes and aquatic invertebrates from upstream following alien fish eradication. The project showed that a chemical called rotenone can completely eliminate alien fish, without detrimental long-term effects on the rest of the river ecosystem, and thereby give our native species back some room to survive – an aquatic miracle if ever there was one!
Unfortunately though, miracles don’t come cheap. The 2012/13 project which successfully eradicated alien bass from 4 km of stream and rehabilitated riparian habitat cost in excess of R4 million. While several species are desperately in need of this type of intervention, future projects will rest on our ability to acquire the necessary funds – a tough challenge when working to save small, shy aquatic creatures that fall outside of the conservation spotlight. With Fins in the Fynbos I hope to raise the profile of these unique but globally threatened fishes, highlight their struggles and offer a way to invest in their future by supporting badly-needed conservation interventions.

Since I bought my first second-hand aquarium when I was twelve, I have always had one or more aquariums. I even converted a garage into a breeding room where I had 50 aquariums containing around 10,000 liters of water. At the moment, I have two aquariums: a 1,250-liter Tanganyika aquarium and a 250-liter community aquarium with plants. For the past 10 years, I have been working on this website as a writer and photographer.
