Singhi fish seeds refer to the young fry or fingerlings of Singhi (Heteropneustes fossilis), a freshwater catfish species found in India. The seeds are typically dark brown or black and are known for their rapid growth and resilience in low-oxygen environments, thriving even in muddy or stagnant waters. Singhi is a highly nutritious fish, prized for its high protein content and medicinal value. It is widely used in aquaculture due to its hardy nature and market demand.
