摘要：Southern bluefin tuna (Thunnus Maccoyii) is a global resource which is critically endangered. The Committee for the Conservation of Southern Bluefin Tuna (CCSBT) sets commercial quota levels for member nations, including Australia, each year. However, southern bluefin tuna is also a popular “trophy” fish with recreational anglers and the size of the total recreational catch in Australia is unknown but thought to be significant. This study focuses on the recreational southern bluefin tuna catch at Portland, in southwest Victoria and is based on data collected during the 2010 fishing season. The results indicate that the size of the recreational catch at Portland is significant in terms of the management of the fishery. A travel cost study was undertaken to estimate the recreational value of the fishery. The on-site recreational use value (consumer surplus) per person per visit is estimated to be between $33 and $132 and the on-site annual recreational use value of the fishery for this one season is estimated to be between $449,533 and $1,325,124.
