The Decline of Global Abalone (Genus Haliotis ) Production in the Late Twentieth Century: Is there a Future?

Enhancing fishery assessments for an Australian abalone fishery using commercial weight-grade data

“…These confirm that the weight-grade data should be used to aid assessment of the greenlip stocks in Region A. Notably, abalone fisheries have proven difficult to assess and manage, with well documented declines in production having been recorded (Prince, 2004). In contrast, this WZ fishery has demonstrated stable catches for >20 years, and recent assessments indicate the stocks are in a generally strong position (Chick et al, 2009).…”

The novel use of harvest policies and rapid visual assessment to manage spatially complex abalone resources (Genus Haliotis)

“…Despite large investments in assessment, management, and sea ranching, global annual production from the wild has declined from around 29,000 t in 1969 to below 10,000 t in 2003 (Prince, 2004). Australia has the largest remaining commercial abalone fisheries, landing >5000 t per annum.…”

“…The ecology of abalone has important implications for their assessment and management, and these implications have been discussed by Prince (2003Prince ( , 2004Prince ( , 2005. Only a brief summary is found here to provide context for this study.…”

Marine Stock Enhancement, Restocking, and Sea Ranching in Australia: Future Directions and a Synthesis of Two Decades of Research and Development

“…The initial work presented at the first of these symposia involved research into the release of barramundi Lates calcarifer (Rimmer and Rus-100 sell, 1998;Russell et al, 2004) and general genetic marking techniques (Shaklee and Bentzen, 1998), brown tiger prawn Penaeus esculentus (Rothlisberg et al, 1999), and black bream Acanthopagrus butcheri (Lenanton et al, 1999). At subsequent symposia, advances in research have continued to be presented 105 on these species and new research on species, such as the southern rock lobster Jasus edwardsii, greenlip abalone Haliotis laevigata, and mulloway Agyrosomus japonicus (Loneragan et al, 2004Mills et al, 2004;Prince, 2004;Russell et al, 2004; Gardner et al, 2006;Gardner and Van Putten, 2008a,b;Potter et al, 2008;Taylor and Suthers, 2008;Taylor et al, 2013a,b). Despite the depth of research in marine stock enhancement, restocking, and sea ranching in Australia, larger-scale, continuing release programs of fisheries for enhancement and restocking, like those in other countries, such as Japan, China, the United States, Canada, and Norway, have not yet been implemented.…”
