项目摘要
Phytoplankton are free-floating plants found in marine and freshwaters that form the base of the aquatic food chain. A subset of the phytoplankton may be harmful to human health or to human use of the ecosystem. The species that cause harm are referred to as 'Harmful Algae' with the term 'Harmful Algal Bloom' (HAB) commonly being used to describe their occurrence and effects.Some HABs can be harmful to humans through their production of biotoxins that are concentrated in the flesh of filter feeding shellfish, leading to a health risk if the shellfish are consumed by humans. Other HABs can kill farmed fish though toxicity, interaction with the gills or anoxia. HAB events of either type can have serious financial consequences for aquaculture.In most locations HABs are natural events with their timing, location, magnitude and toxicity being spatially and temporally variable. Early warning of events can therefore be used to protect health and minimise economic losses.Moreover, HAB events are not random, but a product of their environment. So through a combination of monitoring of the causative species and their toxins, and expert interpretation of these data and other available environmental information, it is possible to produce short term (~ 1-2 week) risk forecasts of HAB location and severity (akin to a weather forecast).In the UK we have since 2015 been operating a weekly HAB and biotoxin alert and forecast system. It operates from the web site www.HABreports.org and contains products that the aquaculture industry can use to better understand the HAB risk in their location and hence take mitigation action to safeguard human health and prevent economic loss. The alerts are based on the synthesis and graphical presentation of multiple data streams including: the abundance of different HAB species, concentrations different of shellfish biotoxins, satellite derived sea surface chlorophyll (an index of overall phytoplankton biomass), sea surface temperature and meteorological information. Historical trends are summarized graphically in map and chart based format, current conditions are presented on a map and through a high/medium/low risk "traffic light" index and expert interpretation is used to produce a forward looking risk assessment.In this proposal we intend to transfer this technology to Malaysia, a DAC country in South East Asia with a significant and growing aquaculture industry related to both finfish and shellfish, and which suffers from HABs though fish kills and episodes of shellfish poisoning. HABs are frequent in Malaysia, with recent events including a fish kill that an estimated to have cost industry $ 2.6 million. In 2013 a paralytic shellfish poisoning outbreak resulted in four deaths and left more than 60 other victims ill after consuming contaminated shellfish. Early warning of HABs in Malaysia will warn regulator and consumers of potential health risks from contaminated shellfish (or sometimes fish) and allow aquaculture businesses to take mitigation measures, e.g., shellfish can be left in situ until toxin depurates, fish cages can be "fenced" using perimeter skirting, fish can be harvested early or transferred to land facilities.In this project UK and Malaysian scientists and fishery regulators will work together to transfer the HAB early warning technology operating in the UK to Malaysia. This will allow us to produce a Malaysian HABreports web site and mobile phone app that includes a traffic light (low, medium, high) index of current risk in different locations and an expert interpretation based forecast of risk for the coming week. Following the project the Malaysian Government will be in a position to continue to produce these risk assessments, providing enhanced ongoing support for the aquaculture industry and public consumers of seafood. Demonstration of our approach will also lead to its potential application elsewhere in the region.
浮游植物是在海洋和淡水中发现的自由漂浮的植物,形成水生食物链的基础。浮游植物的一个子集可能对人类健康或人类对生态系统的使用有害。造成危害的物种被称为“有害藻类”,“有害藻华”一词通常用来描述它们的发生和影响。有些有害藻华会产生生物毒素,集中在滤食性贝类的肉中,对人类有害,如果人类食用贝类,会对健康造成威胁。其他有害藻酸盐可通过毒性、与鳃的相互作用或缺氧杀死养殖鱼类。在大多数地方,有害藻华是自然事件,其发生的时间、地点、规模和毒性在空间和时间上都是可变的。此外,赤潮事件并非偶然发生,而是环境的产物。因此,通过对致病物种及其毒素的监测,以及对这些数据和其他可用环境信息的专家解释,可以对HAB的位置和严重程度进行短期(约1-2周)风险预测(类似于天气预报)。在英国,我们自2015年以来一直在运行每周HAB和生物毒素警报和预报系统。它通过www.HABreports.org网站运作,其中载有水产养殖业可以用来更好地了解其所在地的有害藻华风险的产品,从而采取缓解行动,保障人类健康,防止经济损失。这些警报是基于多个数据流的综合和图形显示,其中包括:不同有害藻华物种的丰度、贝类生物毒素的不同浓度、卫星得出的海面叶绿素(浮游植物总生物量指数)、海面温度和气象信息。历史趋势以地图和图表格式以图形方式总结,当前状况在地图上通过高/中/低风险“红绿灯”指数呈现,并使用专家解释来进行前瞻性风险评估。在本提案中,我们打算将该技术转让给马来西亚,马来西亚是东南亚的一个发援会国家,拥有与长须鲸和贝类相关的重要且不断增长的水产养殖业,并且由于鱼类死亡和贝类中毒而遭受有害生物的危害。有害生物在马来西亚很常见,最近发生的事件包括一次鱼类死亡,估计造成260万美元的损失。2013年,一场麻痹性贝类中毒爆发导致4人死亡,另有60多名受害者在食用受污染的贝类后患病。马来西亚的有害生物预警将警告监管机构和消费者受污染贝类(有时是鱼类)的潜在健康风险,并允许水产养殖企业采取缓解措施,例如,贝类可以留在原地,直到毒素被净化,鱼笼可以用周边的踢脚板“围栏”,鱼可以提前收获或转移到陆地设施。在这个项目中,英国和马来西亚的科学家和渔业监管机构将共同努力,将在英国使用的HAB早期预警技术转移到马来西亚。这将使我们能够制作一个马来西亚HABreports网站和移动的手机应用程序,其中包括不同地点当前风险的交通灯(低,中,高)指数和未来一周基于专家解释的风险预测。在该项目之后,马来西亚政府将能够继续进行这些风险评估,为水产养殖业和公众海产品消费者提供更大的持续支持。我们的方法的示范也将导致其在该区域其他地方的潜在应用。
