Estro SeaNest shelter for cleaner fish
Published 17 November 2022; updated 21 September 2026; 2-minute read. SeaNest is a retractable artificial habitat designed for cleaner fish such as lumpfish in salmon cages. It expands like an underwater pleated curtain, providing shelter and smooth resting/attachment surfaces; the product is 10 m long when extended and retracts to 45 cm for storage. The article says improved hiding/resting conditions may improve cleaner-fish welfare and sea-lice removal, reducing reliance on other delousing methods.
The patented product is made mainly from food-grade HDPE and POM, with no loose plastic parts; the company says it does not release microparticles. It swivels with currents and is positioned for strong-current sites. Operators can clean it with standard site/workboat equipment such as high-pressure washers. The page says it can last several seasons, can be repaired/overhauled by Estro, and replaced parts are recycled into new plastic products.
Market context: the article cites 3.7 million tonnes of global salmon-market volume in 2018 and a projection of 4.7 million tonnes by 2024; Norway was described as supplying over 50% of global salmon. These figures are historical. Target markets named are Iceland, Norway and Scotland, with interest elsewhere.
