Figure 2.2.3 Net cages used for silver perch and Murray cod production in the ring tank at Loch Eaton Figure 2.2.4 Floating raceway system developed for intensive fish production deployed in the ring tank at Loch Eaton 6
2.3 Fish Species Silver perch (Bidyanus bidyanus) were selected for initial trials as they are readily available from hatcheries as fingerlings. This species forms the majority of native freshwater fish production in Australia with the majority of product being sold live to markets and restaurants. Although primarily grown in pond systems this species has shown promise in net cages and other more intensive tank based production systems. Murray cod (Maccullochella peelii peelii) was selected because it has a demonstrated potential for higher density production particularly in tank systems (Gooley and Gavine, 2003). It is an emerging species which has a higher value than silver perch although the relative cost of fingerlings for Murray cod are also higher. Golden perch (Macquaria ambigua ambigua) is another emerging native freshwater fish. While hatchery production of this species is well established virtually all stock is used for recreational stocking activities. The primary issue for this species is the weaning of fingerlings onto artificial diets. Recent research by DPI&F has demonstrated successful weaning strategies and good growth characteristics of this species under culture conditions (Herbert and Graham, 2004ab). 7
