Aqua feed cultivating cleaner fish

项目摘要

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.

全世界的鲑鱼农场因针对鲑鱼的海虱的侵扰而遭受了破坏。不可否认的是需要大量健康的清洁液以控制（饮食）养殖鲑鱼的海上奶酪。但是，当前的方法是从“野生”中提取清洁鱼，并在营养不足的饲料中囚禁。结果，死亡率很高，海虱数量继续在鲑鱼农场内泛滥。挪威和苏格兰的萨尔蒙产量每年下降约10％，使鲑鱼行业每年损失损失的收入中的鲑鱼产业造成的收入损失。ANTI-PARASITICITIC，用于控制海洋的pare虫药物以控制海洋的毒品，可以对环境毒品产生影响，并降低了水质的质量。使用清洁剂（从野外提取的幼虫）是一种已建立的替代方法，但是由于营养缺乏和效率低下的喂养机制，死亡率极高。结果，“野生”的股票正在减少。在此提出了一种新的方法，即一种新的方法，可以在孵化场内可持续地捕获清洁剂。该方法将大大减少从“野生”（允许股票恢复）中收获清洁液的需求，并为鲑鱼农民提供不间断的无疾病清洁剂鱼类的供应。
