A family cannery in Castro Urdiales

Conservera Castreña S.A. is a Cantabrian cannery producing fish preserves and salted fish at its processing and packaging facility in the Sámano Valley in Castro Urdiales. Founded on August 8, 1986, it began manufacturing on October 26 of that year. The company describes itself as a family business that makes its products entirely at its own facilities.

Products and preparation

The catalog focuses on Cantabrian fish, especially anchovies. The company says it works with artisan-caught fish: anchovies caught with purse-seine nets and northern bonito caught one fish at a time with pole and line. Products are made without artificial additives, using natural ingredients, with quality controls from the arrival of fresh fish through shipment to the customer.

• Salted anchovies
• Northern bonito

Prices shown in the online store range from €3.50 for the RR-50 size to €34 for RR-365, including VAT.
