Long-nosed Fur Seal Status

New Zealand fur sealThe long-nosed fur seal (Arctocephalus forsteri) is listed as rare under the Tasmanian Threatened Species Protection Act 1995. It was previously known as the New Zealand fur seal.

Why is it a threatened species?

These seals are listed as threatened in Tasmania because their numbers are low here. They are restricted to only two breeding site within Tasmanian waters, Maatsuyker amnd Tasman Island.

Females reach sexual maturity at four years of age and only produce one pup per year so they are slow reproducers. Another threat to seals is their persecution by fishermen who feel seals are a threat to the fishing industry.
 

How did their numbers get so low?

All seal species occurring in Australian and New Zealand waters suffered from severe and unregulated exploitation during the early colonisation and economic development of Australia. From about 1798 to 1820 the sealing industry was huge. Initially vessels came from all over the world to seal in Bass Strait because seal numbers were so plentiful. The long-nosed fur seal was the most prized for its beautiful fur.

Competition was intense and the seal numbers were rapidly depleted. Soon sealers had to search further afield in New Zealand and other Subantarctic islands. By 1825 all significant and easily accessible seal colonies had either been severely reduced or eliminated.

Why are their numbers still low?

Although sealing has been prohibited in New Zealand and all Australian states for at least 50 years, the long-nosed seal is still considered rare here. In Tasmania their numbers may be as low as only several thousand and they have not repopulated traditional areas such as Bass Strait.

One reason for this is they are slow reproducers. Up to 15 per cent of pups die before reaching two months of age and more die at sea as a result of net and other marine debris entanglements. Fishermen illegally shoot seals for interfering with fishing gear. 

What is being done?

Several educational programs have been undertaken to try and reduce the amount of marine debris in our waters. One of our wildlife officers developed plastics free bait boxes in conjunction with local industries.

Seal populations are continually monitored and information has been gathered on their diet. It is hoped this information can be used to develop methods to reduce the interaction of seals with fishermen and their gear.
