The Australian Jade Perch
The jade perch (Scortum barcoo) is a freshwater omnivorous fish with a heavily built body paired with a small head. The species is also distinguished by the presence of one or more black spots on its body. Native to Australia, the species is being farmed in recirculating systems and intensive ponds in China, Malaysia and Singapore. This is largely due to its relatively fast growth rate and acceptance of pelleted feeds in aquaculture conditions.
Much of the market interest in this species is due to its appealing taste and reportedly high omega-3 fatty acid content. Omega-3 fatty acids can refer to α-linolenic acid (18:3n-3), which can be found in high amounts in some plant oil sources such as linseed, or those with longer chains such as EPA (20:5n-3) and DHA (22:5n-3) that are more often associated with wild-caught marine fish. Omega-3 fatty acids are well known to be healthful for the human consumer over fatty acids that are saturated (SFA), monounsaturated (MUFA) or omega-6, which has promoted the jade perch’s healthy image.
