Semi-autonomous cleaner fish feeding system

三文鱼养殖者认为海虱是他们产业的最大威胁。在过去的十年里，挪威和苏格兰的三文鱼生产者每年因寄生性海虱感染而损失约26万吨(10%)，每年损失约2.75亿GB。自2016年以来，养殖和野生三文鱼的批发成本上涨了50%，从苏格兰到挪威和智利的养鱼户试图解决海虱问题。抗寄生虫疫苗有助于控制海虱，但治疗方法对环境有害，降低了消费者的鱼质量。首选的替代方案是使用清洁鱼类(例如，乌鱼和团头鱼)，它们机会性地吃鲑鱼饲料颗粒(每隔2小时)，并通过吃鲑鱼上的海虱来补充它们的饮食；目前还没有满足清洁鱼类营养需求的饮食。因此，清洁鱼会患上与饮食有关的白内障，减少海虱的消耗--海虱继续激增。目前，没有专门满足清洁鱼营养需求的饲料。World Feed旨在设计一种定制的清洁鱼类饮食和喂食站，这将允许鲑鱼养殖者自动喂养清洁鱼类。

Salmon farmers consider sea lice as the biggest threat to their industry. Over the last decade, salmon producers in Norway and Scotland have lost ~260,000T/yr (10%) from parasitic sea lice infestation, costing ~£275m/year. Wholesale cost of farmed and wild salmon rose 50% from 2016, as fish farmers from Scotland to Norway and Chile tried to tackle sea lice.Anti-parasitic vaccines help control sea lice but, treatments are environmentally toxic and reduce quality of fish for consumers. The preferred alternative is to use cleaner-fish (e.g. wrasse and lumpfish) which opportunistically graze on salmon feed pellets (every 2-hours) and supplement their diets by eating the sea lice off the salmon; there are no diets currently available which meet the nutritional needs of cleaner-fish. As a result, cleaner-fish develop diet-related cataracts, reducing sea-lice consumption - sea lice continue to proliferate.Presently there is no feed which specifically meets the nutritional needs of cleaner-fish. World Feeds aims to engineer a bespoke cleaner-fish diet and feeding-station, which will allow salmon farmers to autonomously feed cleaner-fish.
