  1. Translocate mammals away from aquaculture systems to reduce human-wildlife conflict

    A study in 1997–2005 at nine Atlantic salmon Salmo salar farms in the Tasman Sea and Southern Ocean, Tasmania (Robinson et al. 2008) found that more than half of Australian fur seals Arctocephalus pusillus doriferus and New Zealand fur seals Arctocephalus forsteri translocated away from farms were recaptured at the farms and most returned after multiple translocations. Overall, 56% of relocated fur seals were recaptured at farms between 2 days and 6 years after release in other areas. Of those seals recaptured, approximately 80% returned after being translocated 2–62 times. The authors state that the actual number of seals that returned is likely to be higher as some may have evaded capture. In 1997–2005, more than 4,100 translocations of 954 microchipped seals were carried out. Seals were captured in baited traps at nine salmon farms and released at multiple locations up to 520 km away. Numbers of recaptured seals were recorded during trapping at the nine salmon farms each year in 1998–2005.
