I want to know the answer to the following question:
Which company is the world's oldest canned fish producer?
All the background I'm provided with is that "Portuguese processed fish products are exported through several companies, under a number of different brands and registered trademarks, such as Ramirez (the world’s oldest active canned fish producer), Bom Petisco, Nero, Combate, Comur, General, Líder, Manná, Murtosa, Pescador, Pitéu, Tenório, Torreira and Vasco da Gama.[citation needed]". Is that enough to answer the question?
Answer: yes
