    Purse seine

    • this is the method preferred by Rio Mare
    • it involves the use of freezer vessels up to 100 metres long, that can stay in the sea for 2-3 months
    • once a shoal of tuna is spotted, a net is dropped from the large fishing trawlers and, with a circling manoeuvre, the net is closed to form a sack (seiner)
    • the fish is lifted aboard and immediately transferred to large freezers (-18°C), to guarantee maximum hygiene and traceability

    Fishing methods and vessels


    • an almost artisanal fishing method that Rio Mare promotes in the Solomon Islands, a developing country
    • it takes place close to the coast and results in the fishing of small tuna such as Skipjack tuna
    • once the shoals are spotted, the fishermen throw small fish into the water as bait and lower their rods
    • the tuna is reeled in on the hook one-by-one
    • the boats used by Rio Mare have a modern fish freezing system onboard that guarantees high standards of security.
  • Processing

    Fishing site buildings

    Preparing the loins

    Processing Rio Mare tuna begins in buildings close to fishing sites.
    The fish is defrosted, its head and tail are removed, and it is then cleaned thoroughly and divided into chunks to obtain large and well-cleaned loins that will be sent to the Cermenate plant in the province of Como for the canning phase.
    Products that undergo highly artisanal processing, like the Rio Mare tuna loins, are canned right at the fishing site. They are already packaged when they reach Italy.

    Production at the Italian plant

    Canning and production

    From the fishing sites, the tuna loins conclude their journey at the Cermenate plant (province of Como), which produces over 60% of Rio Mare products.
    With a production capacity of 3 million cans a day, the Cermenate plant is the largest, most modern and most advanced of its kind in Europe.

    The whole production process is completed within just 6 hours: defrosting, canning, sterilisation, packaging and warehouse storage.

    Quality control

    To guarantee the food safety of our products, thousands of controls are also carried out both on raw materials and on the product.
    For instance, 15 000 controls are carried out every year to detect the potential presence of histamine.
