Aquaculture is the fastest growing food sector globally and during 2016 global consumption of farmed fish and shellfish exceeded that of wild caught fish. In UK Atlantic salmon aquaculture is worth >£1 Billion to the economy, however to improve sustainability and expansion two key challenges are improved fish growth and fish health. These two processes do not act independently and our recent results indicate that the insulin like growth factor pathway (specifically the IGF binding proteins) may play a key role in cross talk between these two systems. This PhD will examine gene function, both in vivo (Atlantic salmon) and in vitro (salmon cell culture) using state of the art gene editing approaches (CRISPR/cas9) to define how energy allocation is regulated by the IGF system during immune stimulation. The project is highly relevant for improving farmed fish production and also links with the international consortium to annotate the salmon genome (Functional Annotation of All salmonid Genomes, FAASG, https://www.faasg.org/ and EU H2020 project AQUAFAANG, https://www.aqua-faang.eu/ ), where both supervisors and partners are key members. An international partner in France will enhance the studentship by assisting with aspects of cell culture and immune function. The student will be based within the "Scottish Fish Immunology Research Centre" at Aberdeen and have regular visits to the partner institute at University of Edinburgh, Roslin Institute. The student will have the opportunity for additional training at the international partner labs for example, INRAE, France.

水产养殖是全球增长最快的食品部门，2016年全球养殖鱼和贝类消费量超过野生捕捞鱼类。在英国，大西洋鲑鱼水产养殖业为经济带来了10亿英镑的收入，然而，要提高可持续性和扩大规模，两个关键挑战是改善鱼类生长和鱼类健康。这两个过程并不是独立起作用的，我们最近的结果表明，胰岛素样生长因子途径(特别是IGF结合蛋白)可能在这两个系统之间的串扰中发挥关键作用。本博士将使用最先进的基因编辑方法(CRISPR/Cas9)检测体内(大西洋鲑鱼)和体外(鲑鱼细胞培养)的基因功能，以确定免疫刺激期间IGF系统如何调节能量分配。该项目与提高养殖水产品产量密切相关，还与国际联盟建立了联系，以便对鲑鱼基因组进行注释(所有鲑鱼基因组的功能注释，FAASG，https://www.faasg.org/和欧盟H2020项目AQUAFAANG，https://www.aqua-faang.eu/)，其中监督者和合作伙伴都是关键成员。在法国的一个国际合作伙伴将通过在细胞培养和免疫功能方面的协助来加强学生身份。这名学生将在阿伯丁的苏格兰鱼类免疫学研究中心工作，并定期访问爱丁堡大学罗斯林研究所的合作伙伴研究所。学生将有机会在国际合作伙伴实验室(例如法国INRAE)接受额外培训。
