The demand for summer seafood products, including abalone and eel, has increased due to lucky days in July. The Korea Maritime and Fisheries Development Institute predicts an increase in abalone supply and eel shipments in July, but prices may not reach last year's levels due to existing shipments. Abalone is a high-protein, low-fat food rich in nutrients like calcium, taurine, and arginine, while eel is known for its rejuvenating properties and high vitamin E content.
