  • Recent Trends in Marine Phycotoxins from Australian Coastal Waters
    Review Recent Trends in Marine Phycotoxins from Australian Coastal Waters Penelope Ajani 1,*, D. Tim Harwood 2 and Shauna A. Murray 1 1 Climate Change Cluster (C3), University of Technology Sydney, Sydney, NSW 2007, Australia; [email protected] 2 Cawthron Institute, The Wood, Nelson 7010, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +61‐02‐9514‐7325 Academic Editor: Lucio G. Costa Received: 6 December 2016; Accepted: 29 January 2017; Published: 9 February 2017 Abstract: Phycotoxins, which are produced by harmful microalgae and bioaccumulate in the marine food web, are of growing concern for Australia. These harmful algae pose a threat to ecosystem and human health, as well as constraining the progress of aquaculture, one of the fastest growing food sectors in the world. With better monitoring, advanced analytical skills and an increase in microalgal expertise, many phycotoxins have been identified in Australian coastal waters in recent years. The most concerning of these toxins are ciguatoxin, paralytic shellfish toxins, okadaic acid and domoic acid, with palytoxin and karlotoxin increasing in significance. The potential for tetrodotoxin, maitotoxin and palytoxin to contaminate seafood is also of concern, warranting future investigation. The largest and most significant toxic bloom in Tasmania in 2012 resulted in an estimated total economic loss of ~AUD$23M, indicating that there is an imperative to improve toxin and organism detection methods, clarify the toxin profiles of species of phytoplankton and carry out both intra‐ and inter‐species toxicity comparisons. Future work also includes the application of rapid, real‐time molecular assays for the detection of harmful species and toxin genes.

  • Aquaculture and Marine Protected Areas: Exploring Potential Opportunities and Synergies
    Aquaculture and Marine Protected Areas: Exploring Potential Opportunities and Synergies To meet the Convention on Biological Diversity’s Aichi Target 11 on marine biodiversity protection, Aichi Target 6 on sustainable fisheries by 2020, as well as the Sustainable Development Goal (SDG) 2 on food security and SDG 14 on oceans, by 2030, there is an urgent need to reconcile nature conservation and sustainable development. It is also widely recognised that aquaculture significantly contributes to sustainable development in coastal communities and plays a vital role in ensuring food security, poverty alleviation, and economic resilience. In the framework of integrated management, the time has therefore come to identify the potential opportunities and synergies that can enable aquaculture and conservation to work together more effectively. CONTENT Understanding the various types of aquaculture and their potentialities ……………………………………… 3 The types of MPAs and matrix of interactions showing aquaculture & sustainability principles …… 7 Understanding aquaculture and MPA interactions …… 8 Towards MPAs and aquaculture compatibility and sustainability ……………………………………………10 Background In order to feed the world's growing human population, attention will need to increasingly focus on where the protein needs of the world will be supplied from. While capture fisheries have now reached a plateau of production, marine aquaculture of fish, shellfish and algae has been steadily increasing over the past decades and has become a valid option to make up the protein shortfall. However, one of the major constraints for the aquaculture production sector is the availability of, and access to space. In many coastal areas, competition with other marine activities is already high, mainly because the bulk of marine aquaculture is located close to the shore.

Thank you for always believing in me. ii ACKNOWLEDGMENTS I would like to thank all of the people who helped me collect the specimens for this study, braving the rocks and the waves in the middle of the night: Leigh Ann Boswell, Shannon Evers, and Steffiny Nelson, you were the hard core tako hunters. I am eternally grateful that you sacrificed your evenings to the octopus gods. Also, thank you to David Harrington (best bucket boy), Bert Tanigutchi, Melanie Hutchinson, Christine Ambrosino, Mark Royer, Chelsea Szydlowski, Ily Iglesias, Katherine Livins, James Wood, Seth Ylitalo-Ward, Jessica Watts, and Steven Zubler. This dissertation would not have happened without the support of my wonderful advisor, Dr. Les Watling. Even though I know he wanted me to study a different kind of “octo” (octocoral), I am so thankful he let me follow my foolish passion for cephalopod sexual selection. Also, he provided me with the opportunity to ride in a submersible, which was one of the most magical moments of my graduate career.

  • Experimental Harvesting of Juvenile Common Octopus Octopus Vulgaris, for Commercial Ongrowing in the Azores
    Experimental harvesting of juvenile common octopus Octopus vulgaris, for commercial ongrowing in the Azores CHRISTOPHER K. PHAM & EDUARDO ISIDRO Pham, C.K. & E. Isidro 2010. Experimental harvesting of juvenile common octopus Octopus vulgaris, for commercial ongrowing in the Azores. Arquipelago. Life and Marine Sciences 27: 41-47. Octopus aquaculture is currently restricted to ongrowing of sub-adult to commercial size because culture of paralarvae remains a bottleneck. In most countries, commercial ongrowing rely upon existing pot fisheries for octopuses for obtaining their specimens. In the Azores, such fishery does not exist and effective methods of harvest are required if farming is to be implemented. In this study, we investigated the potential of obtaining sub- adult octopuses on the coast of Faial Island, Azores. Two sets of traps (n=30) consisting of 3 PVC tubes within cement blocks were set-up on two different substrates; soft sediment (Pedro Miguel) and rocky-sand (Pasteleiro) at depth varying between 10 and 30 metres. From June to August 2006, 11 hauls per site were performed. A total of 191 octopuses (from 1.1 to 989 g; average = 135.3 g) were captured. Catches in the soft sediment site were significantly higher than in the other location (CPUE: mean ± SD: 0.33 ± 0.17 vs. 0.15 ± 0.17 octopus trap-1 hour-1*100). The catch was initially dominated by octopus of 300-400 g but as fishing continued, this size classes disappeared and was replaced by smaller individuals. As a result, half of the catch at both sites (51.8%) was composed of specimens with a weight equal or inferior to 50 grams.
