CJ Seafood was founded in 1976 as Samho Corporation and grew in Korea's processed seafood market through its 'Samho Eomuk' (fish cake) and 'Samho Matsal' (crab stick) brands before joining the CJ Group in 2006. The company states it holds the No.1 domestic market share in fish cake and crab stick products.
Its main products span fish cake, crab stick, laver (gim), fried tofu skin (yubu), and grilled fish, with the grilled-fish convenience product line launched under CJ CheilJedang's 'Bibigo' brand and expanded through species diversification and production-line additions.
In 2023 the company acquired full ownership of Samhae Sangsa, a dried seafood wholesaler, from parent CJ CheilJedang, gaining laver brands such as 'Myungga Gim' and export capacity in seasoned laver.
Overseas, CJ Seafood holds a 20% stake in Thailand's Lucky Union Foods, an affiliate that posted 2025 revenue of KRW 203 billion and net income of KRW 29.8 billion, contributing meaningfully to consolidated net income.
Production is spread across four plants in Seongnam, Icheon, Gimpo (Samhae Sangsa) and Buan (Samhae Sangsa), with recent years seeing continued line expansions for snack-type fish cakes and facility upgrades.
In laver, the company competes with Dongwon F&B, CJ CheilJedang, and Pulmuone, while it is viewed as holding a relatively dominant position in fish cake and crab stick. Distribution spans retail channels such as hypermarkets and convenience stores alongside an expanding B2B food-service business.
