| Abstract |
In contemporary times, numerous initiatives are actively underway to advocate for the distribution of cephalopod products as a viable and sustainable alternative in the food industry. Cephalopods play a crucial role in both commercial and ecological aspects; however, their comprehensive understanding remains limited, particularly in Indian waters. This review specifically examines the present circumstances of cephalopods in Indian waters and provides a comprehensive overview of the diverse range of species found in this region, their ecological roles, including habitat preferences and feeding behaviours, the exploitation rate, and the significance of cephalopod fisheries in export and local economies. The distribution includes about 80 commercially exploited species, of which 42 species provide frequent contributions. Ecologically, they are at an intermediate trophic level with opportunistic behaviour and play an important role in regulating food webs. There has been an increasing trend in terms of cephalopod exploitation, with slight fluctuations both in terms of exploitation (205,617 tonnes in 2022) and export (161,503 tonnes in 2022) in the last several years. The exploited resources are exported to different countries, particularly the United States of America, the European Union, and Japan, to generate revenue. Efforts to manage cephalopod fisheries are crucial to ensure their ongoing viability. This review clearly demonstrates that cephalopods in Indian waters are a diverse and economically significant resource with growing exploitation and export demand. It emphasizes the urgent need for targeted fisheries management to balance sustainable harvesting with conservation. By detailing species distribution, ecological roles, and economic impact, this synthesis provides essential guidance for researchers, policymakers, and stakeholders to develop effective strategies for long-term sustainability of cephalopod fisheries in the region. |
