Ecuadorian fishing companies, represented by Tunacons, have responded to claims by Mexican President Andrés Manuel López Obrador about unjustified complaints concerning tuna fishing. They emphasize that their fishing practices are sustainable, with yellowfin tuna having Marine Stewardship Council certification since July and efforts to obtain similar certification for other tuna species. The industry seeks to be excluded from the proposed free trade agreement between Mexico and Ecuador, citing concerns over potential harm to their interests and arguing that their tuna fishing methods are scientifically sound and do not harm dolphins.
