According to the analysis published by the journal Nature, in the last 50 years 90% of large predatory fish have disappeared from the seas. They say that swordfish, gills and sharks are about to disappear and that the current tuna, cod, spent lightning and saucer do not grow as much as the previous ones.

Canadian researchers who have published this article say that new fishing technologies also fish the last fish. The research has focused on the study of large fish communities of four continental platforms and nine ocean systems.

Proposals have also been made to recover the population of large fish. In some cases, they say catches should be cut by at least half and also ban fishing in large protected areas.
