These freshwater species, ranging from vibrant labyrinth fishlike gourami’s to the colorful and diverse rasboras and barbs, contribute significantly to the region’s ornamental fish trade. Additionally, the state benefits from the expertise of local breeders and farmers who specialize in cultivating exotic ornamental fishes and some of these indigenous species, ensuring a sustainable and thriving sector. The ornamental fish sector is an emerging industry with a significant global economic impact. The multibillion-dollar ornamental fish trade involves participation from over 125 nations, with developing countries acting as the primary producers and contributing over 60% of the global supply. This sector is largely dependent upon freshwater fish species.
