Fish farming solutions

We build any size of fish tanks and other equipment.

Family business since 1978

Get to know us

Founded in 1978, Trefjar has remained a family-owned business since its inception. In the early years, we focused on producing fish farming tubs, which quickly became our core business. During the 1980s and 1990s, as the local fish farming industry grew, we built thousands of tanks, becoming a trusted partner for many local fish farming companies.

However, as the demand for fish farming tanks declined, we adapted by venturing into boat building. Initially, we developed our small Skel range, followed by the iconic Cleopatra boats. Since 1990, boat building has been our primary focus, and we’ve crafted approximately 500 custom-built boats in various sizes, tailored to meet the unique needs of our customers.

A few years ago, Trefjar expanded its operations by acquiring Stálorka, a steel manufacturing company specializing in stainless steel, steel, and aluminum production. This acquisition has further strengthened our capabilities, allowing us to provide a broader range of products and services to our clients.

Now that things are scaling up in fish farming, we have utilized our experience and are placing greater focus on aquaculture production.
