Forthcoming events will be held at the 10 Indo-Pacific Fish Conference (10 IPFC ), 2-6 October 2017, Tahiti, French Polynesia (https:// ipfc10.criobe.pf/).

This series of conference was first held in 1978 in Colorado Springs, Colorado (United States) (DINO1) and the 11th DINO meeting will be held for the first time in France. Dinoflagellates and their cysts have shown major research interest for both, biologists working with modern dinoflagellates and geologists working with fossil dinoflagellates. From a biological viewpoint, this major plankton group has major interests in their taxonomy, genetics and ecology, and particularly in the study of toxic dinoflagellates (e.g. Alexandrium, Dinophysis) that can endanger human health through intoxication of shellfish or other organisms higher up the food chain. From a geological viewpoint, fossils dinoflagellate cysts are routinely used in biostratigraphy and palaeoclimatological applications. The international conference DINO11 will serve as a platform for exchanges between biologists and geologists concerning all these themes. The Ciguatera session (H5) is planned as part of Theme H (The Future of Fish and Human Interactions). The call for abstract is open: https://ipfc10.criobe. pf/program/call-for-abstracts/ Scope: Fish products are the nutritional basis of many island populations globally. Ciguatera Fish Poisoning (CFP) results from the consumption of fish that have accumulated ciguatoxins (CTXs) produced by benthic dinoflagellates in the genera Gambierdiscus and Fukuyoa. Over the past decades, the frequency and distribution of CFP have increased significantly in the Indo-Pacific region, a likely consequence of numerous environmental changes in coastal and lagoon ecosystems. Despite increased knowledge about the impacts of climatic cycles and biogeography of Gambierdiscus, ciguatera events are still very difficult to predict. Likewise, the uptake, Session on Ciguatera at the 10 IPFC (Grant applications still open!) 14 Expected Audience: The targeted audience includes researchers (biologists, eco-toxicologist, modelists, economists, etc.) and managers interested in marine biotoxins and seafood safety issues. A group of 20 attendees from the Pacific region, Japan, Europe, and La Réunion is expected. Student Grants Opportunities Two grants could be of interest to HAN readers: Grant 3: Ciguatera fish poisoning in the Indo-Pacific region: incidence, toxin dynamics, impacts on socio-ecosystems, and risk management Grant 5: Women in Marine Sciences in the Indo-Pacific Depending on the number and the quality of applicants, each grant could include one of the following three options: 1/ flight, accommodation and registration fees; 2/ accommodation and registration fees; or 3/ only registration fees. More information can be found on: http://www.laplf.org/dino11/calque dino11.htm A theme session on ciguatera, Ciguatera fish poisoning in the Indo-Pacific region: incidence, toxin dynamics, impacts on socio-ecosystems, and risk management, tissue distribution, accumulation and toxicity of CTXs in fish are still poorly understood. The existence of numerous structural variants (congeners) of the toxin, and the lack of a duly validated reference test for CTXs both constitute a major obstacle in the sustainable exploitation of fish resources. In addition to the direct effects of ciguatera on public health and the economy of nations highly dependent on fish consumption, the fear of ciguatera often leads to reduced fishing in many indigenous Pacific populations, which reminds us that the impact of ciguatera risk must also be examined from sociological and societal perspectives and not only from a public health standpoint. Recently, several initiatives to implement a more efficient management of CFP risk globally have emerged within the scientific community. The main objective of this session is to present the recent advances in these research fields and to foster networking between scientists and stakeholders concerned with seafood safety.
