Invasive bass removed from South African river to aid endangered fish

Conservation groups have removed invasive spotted bass from 8 kilometers of the upper Breekkrans River in South Africa, according to Mongabay. The work, run by Cape Nature, the Freshwater Research Centre and the Fynbos Fish Trust, extends the habitat of the critically endangered doring fiery redfin. Before the project, the fish lived in only a 2-kilometer stretch of the river free of bass. Mongabay reports that a downstream barrier has been built to stop the bass from returning to the treated section.
