Abstract
Minimal information is available with regard to impacts of wild populations of Goldfish; despite being one of the most widely introduced freshwater fishes of the world, and arguably the most popular ornamental fish species. During a control programme for a population of feral Goldfish in the Vasse River, Western Australia, aspects of population demographics and diet were examined. A relatively high growth rate was found with fish, on average, attaining ~ 180 mm TL at the end of their first year of life, a period that coincided with first maturity. Goldfish were relatively long- lived with the oldest fish recorded being in its 11th year of life. The diet was dominated by detritus that was largely comprised of blue-green algae. The potential of this species to exacerbate algal blooms within nutrient enriched environments is discussed.
