Study. A team of Institute for Marine and Antarctic Studies researchers has released the first-ever assessment of the economic and social benefits of Tasmania’s fisheries.
The IMAS assessment analyses trends and changes in a range of both commercial and recreational fisheries where data is available, including abalone, commercial diving, giant crabs, rock lobster, scalefish and scallops.
Lead author Emily Ogier said the assessment details a number of measures of the performance of Tasmanian fisheries, from the economic value of the commercial fishery to the number of recreational fishers taking part.
Dr Ogier said the study shows there have been major changes over the last two decades.
“For example, the market value of the profitable rock lobster industry has risen rapidly due to lower catch limits and resultant higher prices, leading to strong investor demand for quotas.
“The report also reveals some declines in social benefits. The number of fishing vessels, skippers and divers active in our major commercial fisheries and providing employment has decreased steadily over the last 10 years.
“The volume of local wild-caught fish available for Tasmanians to eat has also reduced as catches of local favourites, such as striped trumpeter, have dropped and the proportion of lobster and abalone exported has remained high.”
The number of Tasmanians participating in recreational fishing has fallen significantly overall, although not for potting or diving for lobster, the research shows.
“This assessment will provide industry, government and the community with a better understanding of how our fisheries are changing and the emerging trends,” Dr Ogier said.
“In doing so, it can help to establish a set of economic and social indicators that can inform future fisheries management, particularly through the development of harvest strategies.”
The authors’ key findings include:
• Abalone and rock lobster are the giants of the commercial industry, with the market capitalisation of private quota holdings in 2016 exceeding $875 million for abalone and $630 million for rock lobster
• The 2016 economic yield for abalone was $66 million (down from $94 million in 2002) and $47 million for rock lobsters
• The availability of locally caught scalefish on the Tasmanian market has fallen due to a 60 per cent drop in catch since 2000-01, while the volume of scallops landed has fluctuated between 4000 tonnes in 2006-07, zero tonnes in 2009-10 and 744 tonnes in 2015-16, due to variability in the number of juvenile scallops adding to the fishery
• The number of Tasmanians participating in recreational fishing fell by one-fifth in the decade to 2012-13 while the number of days they fished each year fell by almost one third
• The number of quota units owned by investors based outside Tasmania (interstate or overseas) has increased to 23 per cent from zero in 1995 for lobster, and to 29 per cent from zero in 1985 for abalone, indicating a dispersal of the economic yield from these fisheries outside the state.
A new IMAS report shows Tasmania’s fisheries generate a range of benefits, such as economic yield, employment and recreational amenity.
