The oil sardine is a coastal, pelagic schooling fish, forming massive fisheries in India. It has high population to doubling time of less than 15 months and is probably the largest stock in the Indian Ocean ( Like many other small pelagics, the oil sardine also has shown pbpulation crashes and sudden recoveries in the past. It is a tropical fish, governed by the vagaries of ocean climatic conditions. It is known for its restricted distribution in the Malabar upwelling region along the southwest coast. It attains a maximum total length of about 22 cm and plays a crucial role in the ecosystem as a plankton feeder and as food for large predators. The annual average production is 3.8 lakh tones (15% of all India total catch) valued at about Rs 350 crores. It is a cheap source of protein and forms a staple, sustenance and nutritional food for millions of coastal people.
