Marine biologists investigate southern bluefin tuna
AMONGST all the excitement of anglers hauling in massive tuna each week, a group of dedicated scientists are looking into the finer details of southern bluefin tuna.
Marine biologist Dr Julian Pepperell, four students from Deakin University and a host of industry specialists were in Portland last week investigating the majestic species to best understand the steady stream of tuna that frequent Portland each year.
Dr Pepperell’s ‘Enhancement of citizen science in the recreational fishery for southern bluefin tuna in Victoria’ project collected important biological data and material from otherwise difficult-to-access species for the purposes of research and management.
“We’re taking samples of the fish’s gonads (testis or ovary) and otoliths (ear bones),” Dr Pepperell said.
