Shrimp currently sold in Tunisian markets for 10 dinars are not a local species, according to Hela Jaziri. Jaziri, a member of Tunsea for participatory science, said the seafood is an invasive ocean species rather than a local variety. Tunisian fishermen caught the shrimp, she explained during a radio interview. Her account addressed how an imported product had reached consumers at such a low price. No species name or information about Jaziri's method for verifying the origin was released. The explanation raises questions about labeling and traceability of inexpensive seafood.
