Fleet

Calvo Group  has  its own fleet consisting of 6 purse seiners, 2 reefer vessels and 1 auxiliary vessel.

The tuna boats Montecelo (IMO – International Maritime Organization – no. 7409152), Montelape (8021775), Montealegre (8021763), Montelucía (9232668), Montefrisa-9 (7409176) and Monterocío (8919453) fish tropical species (under no circumstances bluefin tuna) in international equatorial waters and countries lying along the shores of the East Atlantic Ocean (Angola, Cape Verde, Ivory Coast, Guinea Bissau, Gabon, Sao Tomé and Principe and Sierra Leona), Eastern Pacific Ocean (El Salvador and Perú) and Central and Western Pacific Ocean (Kiribati, Tuvalu and Tokelau).

Once our ships have left port, they use different techniques to locate tuna shoals, from binoculars to electronic equipment. Our capture technique is known as purse seine net, which takes advantage of the tendency among tuna to form schools. The ship, aided by an auxiliary vessel called a panga, surrounds the shoal of fish with a net. The boat closes the net by pulling and tightening the cable slotted through the rings round its base. Once the purse shape has been made, the tuna are taken on board using smaller, hand-held nets. The complete fishing manoeuvre is known as largada, or spreading the net.

The fishing periods are divided into intervals of time, from the moment the boat leaves port, until it returns with its hold full of tuna. We call this a ‘tide’.

Once the tuna boat is back in port, it transfers its load to reefer vessel of Calvo Group fleet: Montelaura and Montecruz. Calvo Group tuna boats are forbidden to transfer their load in the open sea, both due to our commitment to use only the best fishing practices and for reasons of security for the load and the crew. The refrigerator merchant ships transport the raw material to the Calvo Group production plants in perfectly controlled temperature and humidity conditions.

Calvo Group recognises the Agreement on the International Dolphin Conservation Program (AIDCP), promoted by the Inter-American Tropical Tuna Commission (IATTC) in their definition of the fishing product as “Dolphin safe”.

All of the Calvo Groups ships strictly meet the EU health requirements. They are inspected and certified as EU authorised establishments; as such they meet all health and hygiene conditions, always keep the fish in cold storage and implement correct health measures.

Also, all our ships carry international observers who verify that our captures have been made in compliance with the regulations and criteria established by the Regional Fishing Management Organisations (RFMO), which control and regulate the fishing of tropical tuna. These observers also provide valuable fishing data both to the RFMO, with a view to providing input to management decisions, and to scientific organisations like the Instituto Español de Oceonagrafía (www.ieo.es). On the other hand, the countries with whom the ships’ flags are registered carry out strict document controls and in-port inspections, in addition to monitoring the boats using GPS satellite tracking systems that permit the authorities to verify at all times the place where the boats are fishing and whether or not they obey the relevant guidelines. Only after having made these verifications can boats issue the obligatory certificates of capture in the endeavour to counter IUU fishing (Illegal, Unreported and Unregulated).

Below we give a series of links to different RFMO. These websites provide general information on the objectives of the organisations, their composition and the latest evaluations of fish stocks, recent management measures adopted and the reports drawn up by their compliance committees.
