The 19th International Conference on Harmful Algae (ICHA) Mexico 2020

项目总结/摘要 会议将于2020年10月11日至16日在墨西哥南下加利福尼亚首府拉巴斯举行。这 会议每两年举行一次，是唯一一次专注于研究的重大国际科学活动 和有害藻类事件的管理。通常有来自50-60个国家的500-600名参与者。 有害藻华（HABs）是海洋和淡水生态系统中的一种主要自然干扰， 受影响地区的公共卫生、鱼类和贝类消费者和生产者、饮用水供应和生态系统 地区ICHA 2020科学计划将促进HAB研究人员和管理人员之间的讨论， 在世界各地，从而促进参与者之间的合作和跨学科， HAB领域的发展。而引起人类多种中毒综合征的主要病原体 (e.g.,海洋用Alexandium属、Dinophysis属、Pyrodinium属、Gymnastinium属和Pseudo-nitzschia属 淡水系统中的鱼腥藻、束丝藻和微囊藻）继续在我们的 沃茨，在监测这些物种及其毒素以及管理 它们对人类健康和经济的影响确实是多种多样的。人类健康问题包括 麻痹性、麻痹性、健忘性、神经毒性和阿扎匹酸贝类中毒综合征（PSP，DSP，ASP， NSP和AZP，以及雪卡毒鱼中毒（CFP）和一系列中毒问题 是由淡水蓝藻引起的然而，在过去的几十年里， 压力源增加，推动我们的沿海和淡水系统发生重大变化。所以我们的 检测和管理新的或正在出现的生物及其毒素的影响的能力至关重要， 重要的是，需要管理更确定的问题。有害藻类的社会影响 问题是多方面的，不仅涉及渔业和水产养殖业以及人类健康， 其他部门，包括旅游业，航运，海水淡化和可再生能源供应。因此有 继续需要将基础科学转化为知识，以帮助克服这些重大和 越来越多的社会挑战。这一目标体现在本次会议的主题“从基础研究到 未来的应用”。多个主题会议将展示重要的科学进展，并强调 在一个快速变化和复杂相互作用的世界中，有害藻类的影响。科学家和 来自地球仪数十个国家，特别是发展中国家的管理人员将促进 交流关于最新进展的信息，并促进制定减轻 有害生物。

Project Summary/Abstract The conference will be held October 11-16, 2020 in La Paz, capital of Baja California Sur, in Mexico. This conference is held every two years, and is the only major international scientific event focused on the research and management of harmful algae events. Typically, there are 500-600 participants from 50-60 countries. Harmful algal blooms (HABs) are a major natural disturbance in marine and freshwater ecosystems that impact public health, fish and shellfish consumers and producers, drinking water supplies, and ecosystems in affected regions. The ICHA 2020 scientific program will foster discussions among HAB researchers and managers from around the world, thereby facilitating collaborations among participants within and across disciplines for the advancement of the HAB field. While the major causative organisms of multiple human poisoning syndromes (e.g., the genera Alexandrium, Dinophysis, Pyrodinium, Gymnodinium and Pseudo-nitzschia for marine systems, and Anabaena, Aphanizomenon and Microcystis for freshwater systems) continue to thrive in our waters, significant advances have been made in monitoring for these species and their toxins and in managing their human health and economic impacts, which are indeed diverse. Among the human health problems are the paralytic, diarrhetic, amnesic, neurotoxic, and azaspiracid shellfish poisoning syndromes (PSP, DSP, ASP, NSP, and AZP respectively, as well as ciguatera fish poisoning (CFP) and a range of poisoning problems cause by freshwater cyanobacteria. Over the last few decades, however, environment and anthropogenic stressors have increased, driving significant changes in our coastal and freshwater systems. Therefore, our ability to detect and manage impacts from novel or emerging organisms and their toxins is of critical importance, as is the need to manage the more established problems. The societal impacts of harmful algae are multiple and do not simply concern fisheries and aquaculture and human health, but increasingly affect other sectors, including tourism, shipping, desalination, and renewable energy supplies. Therefore, there is a continuing need to translate fundamental science into knowledge to help overcome these significant and growing societal challenges. This goal is reflected in the theme of this conference "From Basic Studies to Future Applications”. Multiple thematic sessions will showcase important scientific advances and highlight impacts of harmful algae in a world of rapid change and complex interactions. Participation by scientists and managers from dozens of countries around the globe, especially developing countries, will facilitate the exchange of information on recent advances and foster international strategies for mitigating the effects of HABs.
