Oceans
Oceans are essential to the sustainability of the planet. We must take care of them and manage them responsibly.
Most of our raw material comes from the oceans and it is our duty to contribute to sound resource management and biodiversity protection. That’s why we’ve come up with seven targets aimed at reducing our impact on the marine environment.
Our Commitments
No Data Found
Sustainable tuna in our brands
We are committed to having 100% of the tuna loins in our products come from responsible and sustainable fishing. This means that the tuna employed must meet one or more of these conditions:
- Be MSC (Marine Stewardship Council)-certified.
- Come from a catch included in a robust FIP (Fishery Improvement Project) with an A or B rating as per https://fisheryprogress.org/
- Have been caught without the use of FADs (Fish Aggregating Devices).
- Have been caught by APR (Responsibly-Caught Tuna)-certified vessels.
- Have been caught one by one, using selective methods such as the pole-and-line technique.

Projects

Food traceability is the means to finding and tracking a foodstuff, through all stages of production, transformation and distribution. For us, it is also an essential element of the quality and added value of our products, and therefore is part of the commitment undertaken by the company with respect to responsible management and consumer information.
Traceability and information system
As a product of this commitment, in 2017 Nauterra developed and implemented a food traceability system that allows any consumer to know the path the tuna has taken to reach their table, providing complete and transparent information about its preparation process. This system, certified under the AENOR ISO 22005 Traceability Standard, expands and completes the information already included in the packaging and labeling of our products by specifying the tuna species, the fishing method employed and the fishing zone.
The user only has to provide the batch, time and production line codes that are printed on each can of tuna to receive via email a detailed report with more information on the type of tuna contained in the product, the vessel that caught it, where and when it was caught, by means of which fishing method, in which port in landed, and in which Nauterra factory it was processed.
The traceability system is currently available for tuna products of the Calvo and Nostromo brands manufactured at the group’s plant in Carballo (Spain) and is easily accessible through the websites for each brand (Calvo Traceability; Nostromo Traceability). The rest of the products in our portfolio will be progressively integrated into this food traceability system.
The associated 2025 objective is for 100% of the products we prepare in our range of plants to be 100% traceable from origin to final product.

Responsibly-Caught Tuna Certification
All of Nauterra tuna fishing vessels are certified under the AENOR “Responsibly-Caught Tuna” standard, UNE 195006, which substantiates that the fishing operations of our fleet are conducted in a socially and environmentally responsible manner.
Through audits, AENOR regularly verifies that Nauterra applies the best standards for purse-seine tuna fishing, from both the environmental standpoint as well as the social and labor-related point of view. This includes, but is not limited to, initiatives such as independent observers aboard all company ships; fleet tracking and monitoring via satellite; certification of catches; and compliance with the working, health and safety conditions for workers, as provided for under the International Labour Organization (ILO) Convention for the fishing sector.
All products manufactured and marketed by Nauterra are currently 100% nutritious and healthy. They are rich in protein, vitamins and omega 3, and contain no preservatives. Our commitment is that our product range in 2025 will continue to fulfill current nutrition and health parameters.
The UNE 195006 Standard was developed by the Spanish Association for Standardization and Certification (AENOR) in collaboration with OPAGAC and Spain’s Ministry of Agriculture, Fisheries, Food and the Environment (MAPAMA). It is the first standard to ensure compliance with best fishing practices for freezer seiners in the three-pronged socioeconomic, control and environmental dimension.

As part of our initiatives to protect fishery resources, since 2016 Nauterra is a participant in three Fishery Improvement Projects (FIPs) for the three species of tuna we use in preparing our canned products (skipjack, yellowfin and bigeye). One project is being carried out in the Atlantic Ocean and two are taking place in the Pacific Ocean.
Led by the association of major tuna freezers (OPAGAC), of which Nauterra is a member, and the environmental NGO WWF, these projects are components of the most comprehensive tuna fishery improvement initiative worldwide, as it addresses the management of the three species of tropical tuna at the same time under the three principles of MSC (Marine Stewardship Council) certification:
- Sustainability of tuna stocks
- Minimizing environmental impact
- Effective management of fishing activity
The aim of these projects is to obtain MSC certification for the fisheries. Currently all three projects have the highest rating, A (Advanced Progress), from the independent Fishery Project, which assesses the degree of progress and fulfillment of FIP objectives worldwide.
