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

该项目特别涉及高价值海洋物种的初级畜牧生产，旨在建立知识和水产养殖基础设施的基本基础，以实现经济和低碳的“绿色”欧洲龙虾养殖。这个早期开发项目将开发基于海洋的集装箱养殖（SBCC）系统解决方案的初始设计，最终目的是告知最终原型的生产标准，这些原型可以在稍后阶段进行工业规模的测试。由概念龙虾孵化场（NLH）使用专为饲养牡蛎苗而设计的容器进行的初步海基龙虾试验已经显示出龙虾在单个容器中的良好短期存活和生长。尽管取得了初步成功，但初步试验突出了集装箱设计中的一些缺陷，这些缺陷导致生长和存活的变化，以及部署、监测、检索和维护集装箱所需的大量工时。试验表明，经济可行性是有限的，平均存活率直接随流量而变化。在海水交换量最大的容器中，动物的存活率高达90%，而在流速较低的容器中，动物的存活率约为30%。重新设计系统的形状，材料，培养容器的表面积，使必要的流体流动和技术生产过程，这将使欧洲龙虾的经济养殖。该早期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发现的缺陷。为了告知必要的增长和生存标准，将允许欧洲龙虾的养殖，生物科学和流体动力学技术的专业知识将结合起来。虽然生物背景将提供生长和存活标准，但将对提供必要生长和存活率的海基容器培养（SBCC）系统的流型进行实验研究。位于埃克塞特大学康沃尔校区的一个特殊的流体动力学试验设施将用于调查SBCC设计是否提供了必要的流型。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，将使用自由流和内部流技术中的速度和湍流分布的非侵入式或部分侵入式2D或3D点测量，例如LDA-LDV和热线风速测量法。形状和流动特性。将对内容器进行单独测试，以了解由于i）不同形状设计和ii）例如通过海洋生物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容器设计，并将进一步研究最合适的设计，通过堵塞一定比例的孔来研究堵塞的影响。最后，整个CBSS系统将作为上部结构和内部容器的组合进行研究。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，以开发最终原型，以便在后期阶段进行海上试验。

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 early stage 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 economic 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 early stage 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. 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 holes. 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.
