Plany Freshwater Reservoir provides plentiful fresh water for marine fish farms

- Plany’s Freshwater Reservoir gives marine fish farms nearby access to fresh water for treatments against sea lice and amoebic gill disease (AGD). The reservoir is installed near shore, often close to smolt hatcheries, and filled from an onshore source such as a river. Service vessels can load water there instead of making long trips to harbours or land facilities.
- The article explains that freshwater baths can treat both conditions: fish are immersed for several hours for AGD, while freshwater used for delousing helps loosen lice for brushing. The page presents this as a non-medicinal treatment approach.
- The reservoir is made from abrasion-resistant fabric and is described as lasting 10 years in a protected environment. Each unit is adapted to local currents, waves and weather. Plany developed it with Mowi Norway. A Mowi representative says fetching water from the reservoir takes about one hour versus 20 hours when sourcing from a harbour, saving time and money; fewer wellboat trips also reduce transport emissions.
- The page says the product launched in 2014 and was in use in Croatia, the Faroe Islands, Iceland, Norway and the UK. Plany was seeking expansion in Canada and Chile. It links demand for natural treatments to fish-welfare guidance and consumer expectations for ethically produced food.
- Linked to SDG 9 (Industry, innovation and infrastructure) for efficiency and reduced transport emissions, and SDG 12 (Responsible consumption and production) for facilitating non-toxic fish treatment.
