Aqua-feed for cultivating cleaner fish to eradicate sea lice from salmon

世界各地的鲑鱼养殖场正被以鲑鱼为目标的海虱侵扰所摧毁。不可否认，我们需要更多的健康清洁鱼来控制（吃掉）养殖鲑鱼身上的海虱。然而，目前的方法是从“野生”中提取清洁鱼，并在缺乏营养的饲料中圈养它们。因此，死亡率很高，而鲑鱼养殖场内的海虱数量继续激增。挪威和苏格兰的三文鱼产量加起来每年下降10%左右，每年给三文鱼产业造成数亿美元的收入损失。采用抗寄生虫药物控制海虱，但治疗方法对环境有害，可能影响水质，影响当地野生动物，并降低消费者获得的鱼的质量。使用清洁鱼（从野外提取的幼虫）是一种确定的替代方案，但由于营养缺乏和喂养机制效率低下，死亡率极高；因此，“野生”种群正在减少。世界饲料提出了一种新的方法，养殖清洁鱼可持续圈养在孵化场。这种方法将大大减少从“野生”捕捞清洁鱼的需求（允许种群恢复），并将为鲑鱼养殖者提供不间断的无病清洁鱼供应。

Salmon farms across the world are being devastated by infestations of sea lice that target salmon. There is an undeniable need for greater volumes of healthy cleaner-fish to control (eat) sea-lice off farmed salmon. However, the current approach is to extract cleaner-fish from the 'wild' and breeding them in captivity on feeds that are nutritionally deficient. As a result, mortality rates are significant, and sea lice numbers continue to proliferate within salmon farms.Salmon production in Norway and Scotland combined has been falling by about 10% a year and costing the salmon industry hundreds of millions a year in lost revenues.Anti-parasitic medicines to control sea-lice are adopted but, treatments are environmentally toxic and can impact upon water quality, affect local wildlife and reduce the quality of the fish for consumers. Using cleaner-fish (larvae extracted from the wild) is an established alternative, but mortality rate is extremely high due to nutritional deficiencies and inefficient feeding mechanisms; 'wild' stocks are dwindling as a result.World Feeds presents herein a new approach on breeding cleaner-fish sustainably in captivity within hatcheries. The approach will significantly reduce the need to harvest cleaner-fish from the 'wild' (allowing stocks to recover) and will afford salmon farmers an unbroken supply of disease-free cleaner-fish.
