Seasonal Availability, Proximate Composition and Mineral Analysis of Edible Cephalopods at Digha Coast, West Bengal, India

Abstract

The present study investigates the seasonal availability, proximate composition, and mineral content of edible cephalopods from the Digha coast, West Bengal, India. Cephalopods, including species like squids, cuttlefish, and octopuses, are economically and nutritionally important seafood, contributing significantly to the local fisheries and export markets. Sampling was conducted across different seasons to assess fluctuations in species abundance and biochemical properties. The proximate analysis revealed that cephalopods are rich sources of protein (ranging from 15-17%) with less amount of lipid content, making them a healthy dietary option. Seasonal variations influenced the moisture content (70-80%) and carbohydrate levels, reflecting metabolic changes and reproductive cycles. Mineral analysis showed that these species are high in essential elements such as calcium, phosphorus, and iron highlighting their nutritional significance. Seasonal availability patterns indicated peak landings during the post-monsoon i.e. winter months, corresponding to favorable environmental conditions and spawning activities. The study underscores the importance of sustainable harvesting practices to maintain the ecological balance and long-term productivity of cephalopod resources in this region. These findings contribute to understanding the nutritional potential of cephalopods and support their effective utilization in the food industry.
