Alex Tsappis brings more than 20 years of experience in US aquaculture and has in-depth knowledge of the industry. He was recently hired by NACA to represent the five Norwegian supplier companies: Silikal, Simona Stadpipe, Dynamic FishEye, Mat-Kuling, and Helland Silosystem across both the USA and Canada.

“It was necessary to establish a dedicated sales organisation for the USA and Canada. Alex Tsappis will also handle logistics, service, aftersales and eventually the local assembly of partners’ equipment,” said Bjørn Dørum, general manager of Mat-Kuling, in a press release.

NACA’s presence in North America is also strengthened by the partnership with, Structural Armor in Indiana. The company produces modular composite tanks for aquaculture as well as membranes for upgrading older tanks.

In May, all companies will participate in RasTech 2026 with their own NACA stand. NACA will also host a dedicated RAS workshop on the conference’s opening day. With Alex Tseppis present in the USA to present their compete RAS-solutions to engineering firms, developers and fish farmers, the NACA-companies will have a much better outreach in their new market. 

“The engagement and support from Innovation Norway were decisive in our decision to enter the landbased aquaculture market in the USA and Canada,” said Dørum on behalf of the NACA partners.
