Semi-autonomous cleaner fish feeding system

鲑鱼养殖户认为海虱是他们行业的最大威胁。在过去的十年中，挪威和苏格兰的鲑鱼生产商每年因寄生海虱感染损失约26万吨（10%），每年损失约2.75亿英镑。养殖和野生鲑鱼的批发成本从2016年起上涨了50%，因为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，但治疗对环境有毒，并降低消费者的鱼质量。优选的替代方案是使用清洁鱼（例如濑鱼和圆鱼），其机会性地吃鲑鱼饲料颗粒（每2小时），并通过吃鲑鱼上的海虱来补充其饮食;目前没有可满足清洁鱼的营养需求的饮食。因此，清洁鱼发展饮食相关的白内障，减少海虱消费-海虱继续增殖。目前没有饲料，特别是满足清洁鱼的营养需求。World Feeds的目标是设计一个定制的清洁鱼饮食和喂养站，这将允许鲑鱼养殖户自主喂养清洁鱼。

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.
