Finfish - aquaculture in Western Australia

摘要

David Berry surveys fish farming from Broome to Williams, on off shore reefs and in farm dams, for barramundi, silver perch and black bream, trout and tuna. Aquaculture began in Western Australia at the Pemberton Hatchery in the 1930s with the cultivation of trout to stock rivers and streams for recreational purposes. And while commercial aquaculture was underway by the 1950s, it was cultured pearls based at Broome, not finfish, which got the ball rolling. Today, pearls are worth 150 dollar to 200 million a year with trout production almost static at 335,000 dollar. The combined value of farmed Crustacea and molluscs -yabbies (1.6 million dollar), marron (450,000 dollar) and mussels (950,000 dollar) - easily surpass farmed finfish.
