项目摘要

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.

该项目特别涉及高价值海洋物种的主要牲畜生产，并旨在建立知识和水上养殖基础设施的基本基础，以使经济和低碳'绿色'欧洲龙虾养殖能够实现。这个早期阶段开发项目将开发最初的基于SEA的容器文化（SBCC）系统解决方案，最终目的是告知最终原型的生产标准，这些原型可以在以后的行业规模上进行测试。使用用于饲养牡蛎吐痰的容器进行了著名的龙虾孵化场（NLH）进行的初步海龙虾试验已经显示出良好的短期生存和龙虾在单个容器中的生长。尽管最初取得了成功，但初步试验突显了容器设计中的一些缺陷，这些缺陷导致了生长和生存的差异，以及用于部署，监视，检索和维护容器所需的大量男子小时数。该试验确定经济可行性是有限的，平均生存率直接随流量而变化。在海水交换最大的容器中的动物表现出高达90％的存活率，而容器的流量较低，大约30％。重新设计系统的形状，材料，培养容器表面积，可实现必要的流体流和技术生产过程，这将允许欧洲龙虾的经济农业。这个早期的开发项目旨在通过对特定设计的科学评估来解决这项初步研究中发现的缺陷。为了告知必要的增长和生存标准，这将允许欧洲龙虾的耕种生物科学和流体动态技术的专业知识。尽管生物环境将提供生长和生存标准，但将对提供必要的生长和生存率的海洋容器培养（SBCC）系统的流动模式进行实验研究。位于埃克塞特大学康沃尔大学校园的特殊流体动力测试设施将用于调查SBCC设计是否提供必要的流动方式。 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.由于i）不同的形状设计和ii）造成的阻塞标准，例如通过海洋生长。最初将研究四种不同的内部容器设计，并将通过阻止量化百分比的孔，进一步研究有关阻塞的影响的最合适的设计。最后，将研究完整的CBSS系统作为上层建筑和内部容器的组合。结果将根据科学发现进行评估，并用于提供必要的证据，以开发最终的原型，该原型可以在后期的海上试验中进行测试。
