aquarium fish The vast majority of ornamental fishes in the aquarium trade is of freshwater origin and farm-raised. In the United States ornamental fishes are farmed principally in Florida. Other countries traditionally specializing in breeding and propagation of freshwater ornamental fishes are Thailand, Indonesia, Singapore, China (including Hong Kong), Malaysia, and Japan. More recently the culture of ornamen- tal fish has shifted to regions near consumer centers. For example for the European market, many aquarium fish are now cultivated in countries such as the Czech Republic, Spain, Israel, Belgium, and Holland. Producing fish close to consumer centers is becoming more profitable because transport costs are greatly reduced.
Facilities for the production of aquarium fish are often small compared to major food-fish production operations (Chapman 2000). Fishes are typically raised in small vats and outdoor-ponds, usually in conjunction with indoor facilities that house many small tanks and aquaria. There is a growing interest in the cultivation of ornamental fish in indoor facilities using water-recirculation systems. Cultiva- tion practiced in indoor facilities takes advantage of current developments in husbandry methods and water filtration technologies. Farming ornamental fish in indoor facilities using water-recirculating systems can further minimize any potential impact to the environment by minimizing the escape of farmed fish and reducing water use. The small- scale nature of an ornamental fish farming system, both outdoors or indoors, minimizes any adverse impact to the environment, and seeks to optimize the use of land, labor, capital, and operational costs.
In the wild, most freshwater aquarium fish are caught primarily in rivers and streams using artisanal fishing
