The choice of how to fish has a decisive impact on the equilibrium of the ecosystem and on the future of the sea.

Discover the rules applied by ASDOMAR for its entire production in the Sustainable Fishing Policy and get to know the main fishing methods:


Fishing on free banks provides for the identification of the school of tuna and its circulation with a particular network, of circular shape and of large dimensions that encloses the portion of the sea where the fish are concentrated.

When the shoal in the part is surrounded the bottom net is closed and slowly withdrawn until the fish are concentrated in a small space and can be recovered.

This fishing is carried out by large and modern fishing boats equipped with freezing systems suitable for the industrial use of tuna.


In rod fishing, the tuna shoals are identified in sight . Lures are thrown to attract the tuna and water sprinklers are activated to give the impression that there is a school of small fish on the surface. The fishermen cast their lines and in a few seconds they haul the tuna on board.

For the industrial use of tuna it is essential that even the fishing vessels dedicated to rod fishing, smaller than those for purse seine fishing, are equipped with modern freezing systems on board.

For this reason, of the tuna fished today by the barrel (about 10% of the total caught in the world), only 3-5% is destined for industrial production, while the remainder is destined for local consumption.


All As do Mar branded tuna is produced in accordance with our rules for sustainable fishing.
