“Small samples of skin were collected from southern right whales across New Zealand and Australia using a stainless-steel biopsy dart fired from a modified veterinary capture rifle31 or deployed from a crossbow32. Samples were collected from Bremer Bay/Doubtful Island Bay, Western Australia in 1994 and 1995 as previously described23, and Cape Jervis/Encounter Bay, South Australia, Warrnambool and Port Fairy, Victoria, along the coast of Queensland, New South Wales, and south east Tasmania between 2001 and 2013. In New Zealand, samples were collected from southern right whales around the NZ sub-Antarctic (2006–2009) and mainland New Zealand (2003–2010) wintering grounds as previously described24 and a subset (n = 51) were used here as a comparison. Sampling was carried out following protocols that were approved by the Macquarie University Animal Ethics Committee, Department of Primary Industries Parks Water and Environment Animal Ethics Committee and the University of Auckland Animal Ethics Committee. Sampling was conducted in accordance with and under permits from: Department of Environment, (Australia); Department of Environment and Heritage (South Australia); Department of Primary Industries, Parks, Water and Environment (Tasmania); Department of Natural Resources and Environment (Victoria); Office of Environment and Heritage (New South Wales); Department of Conservation and Land Management (Western Australia) and the New Zealand Department of Conservation (New Zealand).”

“Small samples of skin were collected from southern right whales across New Zealand and Australia using a stainless-steel biopsy dart fired from a modified veterinary capture rifle31 or deployed from a crossbow32, and in one case, a southern right whale carcass. Samples were collected from Bremer Bay/Doubtful Island Bay, Western Australia in 1994 and 1995 as previously described23, and Cape Jervis/Encounter Bay, South Australia, Warrnambool and Port Fairy, Victoria, along the coast of New South Wales and south east Tasmania between 2001 and 2013. One sample was also collected in Queensland in 2014 from a southern right whale carcass, presumed killed due to ship strike. In New Zealand, samples were collected from southern right whales around the New Zealand sub-Antarctic (2006-2009) and mainland New Zealand (2003–2010) wintering grounds as previously described24 and a subset (n=51) were used here as a comparison. Sampling was carried out following protocols that were approved by the Macquarie University Animal Ethics Committee, Department of Primary Industries Parks Water and Environment Animal Ethics Committee and the University of Auckland Animal Ethics Committee. Sampling was conducted in accordance with and under permits from: Department of Environment, (Australia); Department of Environment and Heritage Protection (Queensland), Department of Environment and Heritage (South Australia); Department of Primary Industries, Parks, Water and Environment (Tasmania); Department of Natural Resources and Environment (Victoria); Office of Environment and Heritage (New South Wales); Department of Conservation and Land Management (Western Australia) and the New Zealand Department of Conservation (New Zealand).”
