Port Gager, located on the Baltic Sea island of Rügen, has long been synonymous with premium smoked fish. But behind the scenes, the smokehouse is equally dedicated to environmental stewardship. This article explores the concrete steps Port Gager takes to minimize its ecological footprint while delivering top-quality products. From sourcing to packaging, every stage is guided by a commitment to sustainability that respects the marine ecosystem and the local community.
Responsible Sourcing of Salmon and Trout
Sustainability begins at the source. Port Gager sources its salmon and trout from fisheries and farms that meet rigorous environmental standards. The primary supplier for Atlantic salmon is a Marine Stewardship Council (MSC)-certified fishery in Norway, ensuring wild stocks are managed responsibly. For farmed salmon, Port Gager partners with operations that use recirculating aquaculture systems (RAS), which reduce water usage and prevent waste discharge into natural habitats. Visit our page on our salmon sourcing for more details on supplier certifications.
Trout comes from local Baltic Sea fisheries that adhere to the EU's Common Fisheries Policy quotas. Port Gager also sources organic rainbow trout from a family-run farm in Mecklenburg-Vorpommern, which uses feed free from antibiotics and growth promoters. This local approach cuts transport emissions and supports regional economies.
Energy-Efficient Smoking Process
The traditional smoking process at Port Gager has been modernized to reduce energy consumption. The smokehouse uses high-efficiency electric smokers that consume 30% less electricity than conventional models. Heat recovery systems capture and reuse waste heat from the smoking chambers to preheat water for cleaning and to warm the facility during colder months. This has cut natural gas usage by 15% since 2022.
Wood chips for smoking are sourced from sustainably managed forests in Brandenburg, certified by the Programme for the Endorsement of Forest Certification (PEFC). The chips are kiln-dried using solar panels installed on the smokehouse roof, which generate approximately 20,000 kWh annually — enough to power the drying process and offset 12 tonnes of CO₂ per year.

Waste Reduction and Circular Economy
Port Gager operates a zero-waste policy for fish byproducts. Fish heads, bones, and offcuts are collected by a local rendering company to produce fishmeal and fertilizer. Skins are sold to a tannery in Stralsund that transforms them into leather goods. Even the brine used in curing is treated on-site in a small evaporation pond, with the salt recovered and reused. Non-organic waste is sorted rigorously: cardboard and paper are baled and collected by a regional recycling firm, while plastics are separated and sent to a facility in Rostock.
The smokehouse also minimizes packaging. Fresh fillets are packed in trays made from 80% recycled PET, and the outer boxes are made from 100% recycled cardboard. Customers are encouraged to bring their own containers for takeaway purchases, with a €0.50 discount per container. In 2023, this initiative diverted over 2,000 single-use containers from landfill.
Water Conservation and Effluent Treatment
Water is a critical resource in fish processing. Port Gager has installed low-flow nozzles on all washdown hoses and uses a closed-loop system for cooling water, saving approximately 1.5 million litres per year compared to 2019 levels. The effluent treatment plant uses a combination of screening, sedimentation, and biological filtration to remove solids and nutrients before discharge. Treated water meets Baltic Sea protection standards and is monitored monthly by the local environmental agency.
Community and Environmental Engagement
Port Gager believes sustainability extends beyond its own walls. The smokehouse supports the Rügen Coastal Cleanup initiative, donating €1 for every 100 kg of fish sold to fund beach cleaning operations. Employees volunteer for dune restoration projects in the Jasmund National Park. Additionally, Port Gager sponsors a local educational program that teaches schoolchildren about marine ecology and responsible fishing.

Future Goals and Certifications
Port Gager aims to achieve carbon neutrality by 2030. Planned investments include a 50 kW wind turbine on the property and the electrification of the company's delivery fleet. The smokehouse is also pursuing B Corp certification, with an audit scheduled for late 2024. Current certifications include MSC (chain of custody), EU Organic for the trout line, and ISO 14001 for environmental management. Regular sustainability reports are published annually on the company website.
