Companies of Chinese origin own 63.1% of the jigger fleet that, under the Argentine flag, fishes squid inside Argentina's Exclusive Economic Zone, according to a report by illegal-fishing and marine-conservation researcher Milko Schvartzman, published by the outlet Infobae. The study states that 53 of the 84 jigger vessels that catch the species under the national flag have Chinese companies as owners or "beneficial owners," based on satellite observations from Global Fishing Watch and the translation of official Chinese documents.
