In a closed-down shrimp procession facility at the harbor in Sirevåg, Jæren, Norway a 200-thousand-liter tank is being filled with tropical king prawns. The concrete tank resembles more of a swimming pool than a typical aquaculture tank, both in size and shape, and is internally lined with Protan 724 BlueSafe™. Prefabricated membrane sheets from Protan's factory in Nesbyen have been assembled, customized on-site, and leak-tested by our technicians from Protan Contractor. This result in a liner that precisely fits the tank, providing a solid foundation for the cultivation of high-quality prawns.
Happy Prawns adopts a sustainability profile based on an environmentally friendly production method. No chemicals are used in either food or water, and there is no presence of microplastics or other debris. The closed system eliminates the spread of disease and ensures good animal welfare. There are no emissions from the production that could harm the marine environment.
