13TSB_ACT: Lobster Grower - Develop the technology to fast track the aquaculture potential for the European Lobster

该项目具体涉及高价值海洋物种的初级牲畜生产，旨在建立一个重要的知识基础和水产养殖基础设施，以实现经济和低碳的“绿色”欧洲龙虾养殖。该研究和开发项目将开发初步设计的海上容器养殖（SBCC）系统解决方案，最终目的是为最终原型的生产标准提供信息，以便在后期进行工业规模的测试。由国家龙虾孵化场（NLH）进行的初步海基龙虾试验使用为饲养牡蛎而设计的容器，已经显示出在单个容器中龙虾的短期存活和生长良好。尽管取得了初步成功，但初步试验突出了容器设计上的一些缺陷，这些缺陷导致了生长和存活的变化，以及部署、监测、回收和维护容器所需的大量工时。试验表明，经济活力有限，平均存活率与流量直接相关。在海水交换最大的容器中，动物的存活率高达90%，而在流速较低的容器中，存活率约为30%。在形状、材料、培养容器表面积方面对系统进行了重新设计，使必要的流体流动和技术生产过程成为可能，这将使欧洲龙虾的经济养殖成为可能。本研究和开发项目旨在通过对具体设计的科学评估来解决本初步研究中确定的缺陷。为了了解欧洲龙虾养殖所需的生长和生存标准，将结合生物科学和流体动力学技术的专门知识。虽然生物环境将提供生长和生存标准，但提供必要生长和存活率的海基容器培养（SBCC）系统的流动模式将通过部署一系列上层建筑和单个笼子进行实验研究，并使用法尔茅斯大学Makernow数字生产实验室的设施和专业知识进行设计和生产。位于埃克塞特大学康沃尔校区的一个特殊的水动力测试设施将用于调查SBCC设计是否提供必要的流动模式。为了测量和可视化SBCC上部结构和内部容器设计周围和内部的流动，将使用非侵入式或部分侵入式2D或3D点测量自由流动和内部流动的速度和湍流分布，例如LDA-LDV和热线风速测量方法。它的目的是测试四个上部结构，它们将具有不同的刚度，通道，形状和流动特性。将对内部容器进行单独测试，以了解由于i)不同形状设计和ii)例如由海洋生长引起的堵塞标准而导致的流量变化。将初步研究四种不同的内部集装箱设计，并进一步研究最合适的设计，通过堵塞船体的量化百分比来影响堵塞。最后，整个CBSS系统将作为上层建筑和内部集装箱的组合进行研究。结果将根据科学发现进行评估，并用于提供必要的证据，以开发可在后期进行海上试验的最终原型。

The project relates specifically to primary livestock production of a high value marine species and aims to put in place an essential base of both knowledge and aqua farming infrastructure to enable economical and low carbon 'green' European Lobster farming. This research and development project will develop initial design Sea Based Container Culture (SBCC) system solutions with the end aim to inform about production criteria of final prototypes that can be tested at an industry scale at a later stage. Preliminary sea based lobster trials conducted by The Notional Lobster Hatchery (NLH) using containers designed for rearing oyster spat have already shown good short term survival and growth of lobsters in individual containers. Despite initial success, the preliminary trials have highlighted some deficiencies in container designs that have resulted in variation in growth and survival, as well as high number of man hours required to deploy, monitor, retrieve and maintain containers. The trial identified that the economical viability was limited and that the mean survival rate varied directly with flow. Animals in containers with the greatest exchange of seawater demonstrated survival rates of up to 90% compared with approximate 30% in containers allowing lower flow rates. A re-design of the system in term of shape, material, surface area of culture containers enabling necessary fluid flows and technical production processes, which will allow the economical farming of the European lobster. This research and development project is designed to address the deficiencies identified in this preliminary study through a scientific assessment of specific designs. In order to inform about necessary growing and survival criteria that will allow the farming of the European Lobster the expertise from bioscience and fluid dynamic technologies will be combined. Whilst the biological context will provide growth and survival criteria, flow pattern for Sea Based Container Culture (SBCC) systems that provide necessary growth and survival rates will be investigated experimentally through the deployment of a range of superstructures and individual cages design and produced using facilities and expertise within Falmouth University's Makernow digital production Lab. A special hydrodynamic test facility based at the University of Exeter' Cornwall Campus will be used to investigate if SBCC designs provide the necessary flow patterns. In order to measure and visualise the flow around and within SBCC superstructures and inner container designs non-intrusive or part-intrusive 2D or 3D point measurement of velocity and turbulence distribution in both free flows and internal flow techniques will be used, such as LDA-LDV and hot wire anemometry methods.It is intended to test four superstructures, which will have different stiffness, access, shape and consequently flow characteristics. The inner containers will be tested individually to understand the change in flow as a consequence of i) different shape designs and ii) blockage criteria caused e.g. through marine growth. Four different inner container designs will be initially investigated and the most suitable design will be further investigated regarding the impact through blockage by blocking a quantified percentage of the hull. Finally the full CBSS system will be investigated as a combination of superstructure and inner containers. The outcomes will be assessed based on scientific findings and used to provide the necessary evidence to develop a final prototype that can be tested at sea trials at later stage.
