The many tasks she is performing every day makes her job diverse and challenging.

Janneke van der Linde


Whichever way you look at it: a switch from the notarial profession to fish is quite unusual. Not hindered by any knowledge of fish in general, or Dutch Yellowtail in particular, Mrs. van der Linde-Kikkert has been involved with Kingfish Zeeland from the very beginning and has witnessed and participated in all steps the company has taken to date, while hopefully many more to follow. She started as an office manager, but soon grew into sales and marketing: another switch, and an exciting one too. It offers the opportunity to satisfy a relentless hunger and curiosity for new, for her, unknown areas.

Ms. Ruiter has been working for Kingfish Zeeland B.V. since January 2018. She started as an office manager and sales support. In her current position, she is responsible for all aspects of sales, logistics and supply chain management. Ms. Ruiter is educated in hotel management, business communication, sales and PR. Ms. Ruiter has previously held positions as account manager purchasing & sales, project coördinator logistics in heavy cargo shipping. In recent years she has also had 2 companies under her own management. Her switch to fish farming is a surprising but very good choice.
