In this research paper a Constant Market Share (CMS) approach was employed to learn export performance dynamics of Indian seafood (shrimps and cephalopods) in the major export destinations (EU, USA and select Asian countries), which accounts for a sizeable market for Indian seafood. The Constant Market Share model was used to disintegrate the growth in exports of seafood into market size effect, market composition effect and competitiveness effect. The analysis was performed for the seafood exports for a span of 12 years from the year 1996 to the year 2007, the period during which India had to face severe challenges from evolving food safety regulations in the EU and USA. The analysis was extended to account for the competitiveness at dis-aggregated commodity level. In the present study we observed enhanced competitiveness in the case of cephalopods while shrimp exports were less competitive. To a certain extent it shows that trade facilitating as well as trade restricting effects can coexist as an impact of strict food safety regulations.
