Shetland seafood and shellfish growers are navigating challenges such as Brexit's impact on exports and the aging ferry fleet for transport to the Scottish mainland. Brexit has increased paperwork, costs, and delivery times for exports, especially for added value products. The industry's future relies on government support and innovation, with shellfish farming showing success and oyster production starting. The industry faces challenges like offshore wind development and potential environmental initiatives, but remains resilient and dedicated to maintaining quality and premium pricing for their products.
