Explanation: The National Fish of India is the Hilsa, scientifically known as Tenualosa ilisha. This fish is a significant part of the aquatic life in the Indian subcontinent, particularly in the rivers and estuaries of the eastern coast. The Hilsa is a migratory fish that moves between freshwater and saltwater environments, making it a unique and important species in the region.
The Hilsa is highly valued in Indian cuisine, especially in coastal states like West Bengal, Odisha, and Andhra Pradesh. It is known for its distinctive taste and is a key component of local festivals and celebrations. The fish is also economically important, supporting the livelihoods of many fishermen and contributing significantly to the local economy.
The Hilsa's importance in Indian culture and economy led to its designation as the National Fish of India. This recognition highlights the fish's ecological, cultural, and economic significance. It is a symbol of the rich biodiversity and natural resources of the country.
In contrast, the other options listed are also important fish species in India but are not designated as the National Fish. The Katla (Labeo calbasu) and Rohu (Labeo rohita) are both freshwater fish species that are widely cultivated and consumed in India. The Mrigal (Cirrhinus mrigala) is another freshwater fish that is important in aquaculture and fisheries. However, none of these species have been officially recognized as the National Fish of India.
Understanding the significance of the Hilsa as the National Fish of India is important for students preparing for competitive examinations such as the UPSC, SSC, and banking exams, where questions on national symbols and cultural heritage are common. It is also relevant for those interested in the ecological and economic aspects of Indian aquatic life.
