    Our Honest Product review 

    • Exceptional Nutritional Value: This fish stands out as a high-quality food source, providing an excellent profile of essential amino acids and Omega-3s (which may aid cardiovascular and brain health), making it a healthy option.
    • Eating Experience: Its scaleless body and low number of intramuscular bones make it much easier and more enjoyable to consume compared to many other freshwater fishes (like carps).
    • Vulnerability Concern: Although the widely distributed Sperata aor is generally listed as Least Concern, its local populations in regions like Bangladesh are classified as Vulnerable due to overfishing, demanding a preference for sustainably managed stocks.
    • Market Status: Due to its quality and ease of eating, it fetches a higher price than common carps.

    Usage

    • Culinary Staple: Highly valued food fish used in diverse South Asian cooking, including curries, frying, and grilling.
    • Nutraceutical Source: Due to its richness in fat-soluble vitamins (A, D, E, K) and quality Omega-3s, its fish oil is a valuable product used for health supplements.
    • Game Fish: Also a popular sport fish among anglers due to its large size.
    • Ornamental Export: Smaller species of long-whiskered catfish (such as Mystus gulio and Mystus tengara) are sometimes exported from India for the ornamental fish market.
