In an article published in the journal PLOS ONE, Brazilian scientists show that one of the effects of overfishing in Arraial do Cabo, Rio de Janeiro state, Brazil, is the replacement of large, valuable species by smaller species for which there used to be little demand.
According to the authors, the decline in stocks of Pomatomus saltatrix (bluefish), Epinephelus marginatus (dusky grouper), Caranx hippos (crevalle jack) and Seriola fasciata (lesser amberjack) has been followed by an increase in the capture of less commercially valuable but more abundant species, such as Trichiurus lepturus (beltfish), Balistes capriscus (gray triggerfish), Aluterus monoceros (unicorn leatherjacket), and Priacanthus arenatus (Atlantic bigeye).
