The biodiversity of the Ligurian Sea includes of course also the species that are not intended for human consumption.
Some of these, simply because it's not edible, other because in years past have been the subject of capture in some cases threatens their survival.
It is the case of the moon-fish, which until the 90s was usually caught, and then become a protected species by the European Community, or of the coral, the processing of which in the past centuries brought revenue not indifferent to some of the resorts of the Riviera.
A special case are the cetaceans, in particular striped dolphins, and bottlenose dolphins come to interact with the fishermen directly. In the first place, as competitors in the search of other species are edible, in the second place, because they have learned with the time to take advantage of the fishing systems of the man in their favor. Is demonstrated in fact by scientific studies that these mammals are capable of preying on the networks of the shellfish caught, sometimes going to cause damage to the fishing net themselves.
The bluefin tuna fishery is regulated by quotas established by the European Community. In Liguria is not catchable.
The minimum size of the anchovy catchable.
