The objective of this study is to investigate how Korean seafood exports to India can be expanded to improve the trade balance of seafood. Due to changes in Indian lifestyles, meat prices, and awareness surrounding fish, the quantity of seafood consumed in India is increasing. On the other hand, Korean seafood trade has been in deficit for over 20 years. India's huge market with a population of more than 1.4 billion and the rising consumption of seafood will act as a significant opportunity to Korean seafood exports. Therefore, if Korean seafood exporters understand the current Indian seafood market conditions, it would be of substantial help to increase the export amount of Korean competitive seafood. This study endeavored on how to improve the Korean seafood trade balance, focusing on the Indian seafood market and deriving Korean competitive seafood in the Indian seafood market in terms of econometric methods such as the trade specialization index, the revealed comparative advantage, and the export bias index. Finally, export expansion plans for Korean competitive seafood were made to pioneer the Indian seafood market based on Indian food culture, Indian seafood consumption trends, and Indian seafood distribution environments for five items, including laver, oysters, abalone, fish processed goods, and tuna, all of which were found to be Korean export-competitive seafood.
