The ornamental fish trade is a nascent fisheries-oriented trade sector in Bangladesh. The country’s ornamental fish trade’s centrum is the Katabon Market in Dhaka, Bangladesh’s capital. This study portrays the overview of the ornamental fish trade, the constraints associated, and the likelihoods of this trade in Katabon. The study discovered 33 aquarium shops, and the average business experience of traders was around ten years. A total of 41 varieties of fish had been identified as available for selling, and most of them (53.66%) belong to the fish order Perciformes. Osteoglossum bicirrhosum (Silver arowana; 68000±27838.82 BDT/Pair) was tracked down as the most expensive fish, followed by Cyprinus carpio (assorted koi carp; 8200±2939.19 BDT/Pair). A general marketing channel was identified, initiated with the importers and local hatchery owners, and ended up with the end-users, aquarium keepers. The most sold species was Carassius auratus. The research analysis had identified a lack of suitable policy for the expansion of the trade, adequate knowledge on diagnosis and treatment of diseased fish, research on feeding and breeding technology, integration with other trade, skilled staffing’s involvement, and accurate quarantine procedure as the key constraints impeding the accrual of the trade.
