项目摘要

Aquaculture is the cultivation of aquatic organisms, usually for the purposes of human consumption. Worldwide, fish and shellfish consumption is expanding. Globally wild fish stocks are in decline and aquaculture is rapidly growing in importance. Aquaculture production will continue to support the increasing human demand for seafood to feed both mass and quality markets in different regions of the world.Aquaculture is an increasingly important industry for the UK with exports worth in excess of £500 million. Most UK aquaculture occurs on the Scottish West coast with the dominant cultivated species being Atlantic salmon (Salmo salar) which accounts for 98% of Scottish marine finfish aquaculture. The industry has an export value in excess of £500 million and employs more than 8,000 people mostly in remote locations where other job opportunities are scarce. Currently most aquaculture production occurs in fjordic sea lochs that provides relatively sheltered conditions for the farms. Industry and government have a desire to expand aquaculture production in Scotland but the opportunity to increase capacity within the sea loch environment in limited. Barriers to further expansion include planning issues, the transfer of parasitic sea lice that negatively impact fish health from one site to another, biomass limits imposed by the environmental regulator SEPA to minimise chemical and particulate impact, and the impact of fish killing harmful algal blooms that can be particularly acute in restricted exchange environments such as fjords. The fish farming industry also faces an ongoing battle with environmental campaigners who fear that intensive farming in lochs and fjords is damaging to wild stocks and ecosystems.The development of aquaculture in "offshore" environments outside of sea lochs offers a potential route for the sustainable expansion of the industry. Such locations are still within the coastal marine environment but in more open and exposed water. More dispersive open environments potentially minimise the problems outlined above with the potential for larger farms with reduced inter connectivity and environmental impact. However, these more exposed environments will carry their own risks, for example in terms of potential storm damage. To proceed with the development of offshore aquaculture a better scientific understanding of its potential benefits is therefore required. To achieve this, this project will use a combination of experimental observation at existing and proposed fish farm locations of contrasting exposure, along with previously unavailable industry data to validate existing and new physical and biological mathematical models. These models will then be used to evaluate the potential to reduce sea lice infections, the harmful algal bloom risk, the risk of equiment failure and the impact on farmed fish health of operation in more energetic environments.

水产养殖是水生生物的养殖，通常用于人类消费。全球范围内的鱼类和贝类消费量正在下降，而水产养殖的重要性将继续满足不断增长的人类需求。水产养殖对英国来说是一个日益重要的产业，出口额超过 5 亿英镑，大多数英国水产养殖发生在苏格兰西海岸，主要养殖品种是英国。大西洋鲑鱼 (Salmo salar) 占苏格兰海水鱼类养殖业的 98%，该行业的出口额超过 5 亿英镑，雇用的员工超过 8,000 人，大部分位于其他就业机会稀缺的偏远地区。发生在峡湾的湖泊中，为养殖场提供了相对庇护的条件。工业界和政府希望扩大苏格兰的水产养殖产量，但在海湾环境中增加产能的机会有限。进一步扩张的障碍包括规划问题、对鱼类健康产生负面影响的寄生海虱从一个地点转移到另一个地点、环境监管机构 SEPA 为尽量减少化学和颗粒物影响而实施的生物量限制，以及鱼类杀死有害藻华的影响。在峡湾等受限制的交换环境中，鱼类养殖业还面临着与环保人士的持续斗争，他们担心湖泊和峡湾的集约化养殖会损害野生种群和生态系统。湖泊以外的“近海”环境中的水产养殖为该行业的可持续发展提供了一条潜在途径，这些地点仍然位于沿海海洋环境内，但处于更加开放和暴露的水域中，可能会最大限度地减少上述问题。然而，这些更加暴露的环境也有其自身的风险，例如潜在的风暴损害，以更好地科学了解其潜在效益。因此需要。为此，该项目将结合对现有和拟议的养鱼场位置进行对比暴露的实验观察，以及以前无法获得的行业数据来验证现有和新的物理和生物数学模型，然后将使用这些模型来评估潜力。减少海虱感染、有害藻华风险、设备故障风险以及在更有活力的环境中作业对养殖鱼类健康的影响。
