. >> captain petaia delaverata and his crew are all local.hey use fishing methods their ancestors wouldn't recognize. >> it's quite easier now when there is a school of fish 100 meters away. the sonar can tell you the density of the fish, how many tons there is, how deep it is and how far it is away from the boat. >> once the school of fish has been located, it's doomed. the crew get the nets in position, the trawler starts to circle, and moments later, the tuna are netted. it's so easy that it makes the captain uncomfortable. >> as a pacific islander myself, i would ask one question. will the next generation enjoy this industry as we do now? it's so very easy to catch fish. that's the worrying part, the more boats, more fish harvested from the sea. >> the solomon islands belong to the pacific islands forum fisheries agency, ffa, established to protect fish stocks. other members include australia as well as many small island developing states. countries that don't belong to the alliance aren't allowed to cast their nets within a 200 kilometer
