Top Glass Catfishes Fishing Countries

The glass catfish (Kryptopterus vitreolus), renowned for its nearly transparent body and delicate appearance, is a small freshwater species native to Southeast Asia, particularly Thailand. Unlike larger catfish species targeted for food, the glass catfish is primarily sought after for the ornamental aquarium trade due to its unique see-through appearance and peaceful nature. The top countries involved in the fishing and export of glass catfish are Thailand, Indonesia, and Malaysia, where local fishers often collect them from slow-moving rivers and streams. Thailand stands out as the leading exporter, supplying the majority of glass catfish to the global aquarium market. While wild capture remains common, there is a growing trend toward captive breeding to reduce pressure on wild populations and ensure sustainable trade. The glass catfish industry in these countries is a niche sector within the broader ornamental fish export market, contributing to local economies and supporting small-scale fishers and breeders.
