Sub-theme B: Ensuring Marine Biodiversity, Food Safety and Security

The Indo-Pacific region has been well recognized as the hot-spot of global marine biodiversity. Tremendous efforts have been devoted to the assessment of marine biodiversity, including species richness, geographic distribution, and genetic diversity in the region. In addition to traditional taxonomical tools, the advancement of molecular biology and techniques, including transcriptomic and metagenomic approaches, provides a supplementary tool in classification and assessment of marine biodiversity status. This session will provide a scientific venue for researchers and other stakeholders to discuss and exchange ideas in order to better understand the marine biodiversity of their respective areas. The session welcomes studies on taxonomy by either morphologic, molecular or integrated approach;, and the relationships between species distribution, species composition changes and physical/geographic conditions. The session also includes studies on the diversity of such organisms as nekton, benthos, and plankton that are closely associated to the most productive part of our coastal ecosystems (coral reefs, seagrass-seaweed beds and mangroves).
B09: Status, Trends of Marine Biodiversity and Impacts of Climatic and Anthropogenic Stressors

Marine biodiversity in the WESTPAC region is considered to be the highest in the world.  Such biodiversity provides ecosystem services across the variety of marine habitats from the coast to the deep sea.  For example, coral reefs provide habitats and nursery grounds for many marine organisms which become important and reliable food source not only for marine life but also for humankind as well. However, marine biodiversity has been declining globally in recent years due to both natural and anthropogenic disturbances including climate change, which lead to changes of ecological function and extinction of a number of species. This session welcomes papers related to current status and change of ecosystem structure and biodiversity, interaction among the marine organisms, as well as the impacts of climatic and anthropogenic stressors on marine biodiversity and ecosystem particularly in the WESTPAC region.
B10: Research and Conservation of Endangered Species

Many of the endangered animals, such as dolphins and sea turtles, are top predators or grazers of and important in the marine ecosystem. They are icons of rich biodiversity and healthy ecosystem. They also fascinate and intrigue people by charming elegant appearance and friendly behavior in general. However, many of these megafauna are highly migratory and often come to or encounter habitats in the coastal and brackish waters where human disturbance is intensive. The scientific information of these species is largely deficient due to lack of effective capabilities to study/monitor and this hinders effective conservation of them, especially in the areas of economic/developmental deficiency, and those under increasing impacts from climate change. This session will contribute to improved knowledge and conservation of marine mammals and sea turtles in the region, by bringing together traditional and modern methods and the recent results and information from these studies and conservation. Contributions on other endangered marine species are also welcome.
B11: Sustainable Fisheries and Environmentally Friendly Aquaculture

It is estimated that more than 75 percent of the world’s commercial wild fish stocks are currently being fished at or above sustainable yield. Similarly, aquaculture operations are unplanned, unregulated, and even result in major degradation of local ecosystem services in many parts of the world. To meet rising demand for fish products, ecosystem-based approach should be introduced to the two sectors of seafood production. This session welcomes presentations covering: i) ecosystem-based fisheries and aquaculture, particularly those new ideas on paradigm shifts in policies and practices and case studies having demonstrated social and economic benefits; ii) advances in fishing gear and operations that incorporate knowledge of fish biology and marine biodiversity, reduce bycatch and discards, and introduce green technology; and iii) research findings on commercially feasible sustainable aquaculture modules such as integrated multi-trophic aquaculture systems, environment-friendly feeds and culture of low food chain species etc.
B12: Toxic Marine Organisms and Seafood Safety

It is known that some marine organisms possessing natural toxins cause food poisonings. Some toxins (PSP, ASP, DSP, CFP, and NSP toxins), produced by microalgae, could be accumulated into filter feeding organisms and even transferred to others through food web and make the predators become toxic. Some other natural toxins as tetrodotoxin (TTX) contain in puffers, goby, blue-ringed octopus, snails and crabs, and its origin has not been clear yet. Consumption of such toxic organisms leads to food poisonings, and sometimes even result in fatal accidents. The ever-increasing expansion of seafood poisoning episodes in the Western Pacific poses a threat to human lives. The session invites presentations on natural toxins and their occurrence, accumulation in marine organisms; seafood poisonings caused by marine toxins; and toxin detection and analysis with a view to lessening poisoning problems in the region.
On the other hand, Jellyfish hazard is an emerging issue in global oceans, including the Western Pacific, as it adversely affects humanity by posing a threat to public health and interfering with public systems and ocean ecosystems. Some jellyfish’s stings are venomous, sometimes even fatal, and some jellyfish blooms can clog cooling equipment, even disabling power plant operation. Moreover, some invasive species may cause negative ecological impacts. Given the limited knowledge on jellyfish in the region, this session invites presentations on its various aspects, covering taxonomy, systematics, development, life cycle, venom and first aid treatment study, the pattern, ecological consequence, and countermeasures.
