Palacio de Oriente relies on the sea as its main natural resource when it comes to supplying its principal product lines. Fishing, aquaculture and shellfishing are the main ways in which Palacio de Oriente obtains its stock. That is why it is essential to respect the rules organising and regulating the exploitation of marine resources, avoiding situations of over-fishing that threaten the ecological balance of the marine environment.

100% of the mussels prepared for sale by Palacio de Oriente come from mussel farming platforms placed all along the Galician coast. At Palacio de Oriente we are keen to promote aquaculture as a way to ensure the renewal of fishing stocks and avoid damaging the natural breeding grounds of certain species.



Palacio de Oriente's packaging for Albacore, Yellowfin and other varieties of tuna bear the "DOLPHIN SAFE" mark, which guarantees the use of fishing methods that are not harmful to dolphins.

Not all tuna is created equal...

There are as many as seven different species of tuna, and knowing how to tell them apart will help you to choose your canned goods carefully and be aware of the benefits offered by each of them.

Palacio de Oriente prepares a wide range of products based on three varieties of tuna:

Albacore (Thunnus Alalunga)

This is the most highly-valued of all the tuna species. It is notable for its white and rich meat, its fine texture and its flavour. These characteristics make it ideal to be eaten by itself or with foods that have mild flavours.

It is a fish that has a robust body, is of a dark blue colour and its caudal fin is white-edged.

Yellowfin Tuna (Thunnus Albacares)

This is the species that is most used in the tinned foods sector. Its meat is of a more pinkish colour, with a rougher texture than that of Albacore, and its taste is a bit more intense. It is an ideal ingredient in countless recipes.

It gets the name Yellowfin from the peculiar yellow colour of its fins. It is a fish that has a robust body, is of a dark blue colour, has a caudal fin that is not white-edged and generally very long fins.

Skipjack Tuna (Katsuwonus Pelamis)

Its meat is of a dark colour and has a very intense taste. It gets its name from the bands or stripes on its belly. It is not as big as Albacore or Yellowfin tuna, rarely weighing more than 5 kg.

Red Tides

The natural phenomenon known as a Red Tide occurs when a series of factors, such as water temperature, salinity, light conditions, the availability of nutrients, tides and winds lead to a proliferation of algae. This all leads to an excessive multiplication of a type of algae that produce a biotoxin, resulting in a kind of "biological explosion".

These Red Tides lead to significant damages for the aquaculture sector, which is prevented, during the most acute periods of these tides, from collecting molluscs in the affected areas.

The problem is that the molluscs, both the farmed ones (mainly mussels and oysters) and those that live fully or partly buried in the sand (scallops, cockles, mussels, razor shells, etc.) feed by filtration, and when the red tide produces toxins the mollusc absorbs the toxins and the algae that produced them.

A clear example of this are mussels farms, which are found in groups of platforms along the Galician coast, in an effort to find the waters that are richest in minerals and nutrients. The mussel platforms have to be closed for long periods of time, until the gradual process of filtration reduces the levels of toxins and then eliminates them completely.

Galicia is a world leader in controlling toxins in order to provide a completely safe product to the consumer. To this end, there is a double analysis in place, examining both the molluscs and the sea water. This double analysis, and a rigorous action protocol, allow us to bring to the market products that are 100% safe.

Commitment to sustainability

In order to ensure the sustainability of fish supplies, the company will actively avoid any illegal fishing and will be able to provide the source of all lots of fish marketed. It will only accept supplies from vessels which are authorized in the registers of the Regional Fisheries Organizations (RFMOs) and which are flagged by countries that are members of the RFMOs (or collaborators, if membership is not possible), or have requested that status. It will provide support and recognition of best fishing practices as well as support to fleet control systems and impact management:

  • It will not be supplied with fish that have undergone high sea transshipments and will demand from its suppliers that the fish offered does not come from them.
  • Excluding vessels that do not carry out the total retention of all tunas caught (except those that can not be destined for human consumption), or practice any activity of mutilation of live sharks.
  • Supply of tuna caught with large purse seiners with a continuous monitoring of their position by VMS, as well as the presence of an observer, whether human or electronic, throughout their fishing activity.
  • Commitment to supply tuna from vessels using "non-enmeshing" FADs in order to minimize Bycatch.
  • Prohibition of supply of tuna caught in fisheries where there is evidence of use of explosives and poison.
  • Commitment to supply tuna caught by vessels registered in the Proactive Vessel Register (PVR).
