Établissements Bertrand — Machines et fournitures ostréicoles

History

60 years alongside oyster farmers

Craftsmanship refined for over 60 years

Parc ostréicole

Roger Bertrand is only 23 when he sets up his marine forge in Bourcefranc in May 1957. He works alone at first, then hires a blacksmith and later more workers.

It is a time when oyster farming is booming but has few mechanical resources. Roger Bertrand grows close to the oyster farmers — and this is how he brings the first oyster tables to market.

In the 1970s, Roger Bertrand builds a tubular washer, the first oyster-farming machine and oyster farming’s first step towards mechanisation. A year after its launch, around a hundred tubular washers are sold.

In the 1980s comes the machine to destock collector tubes: a machine for cutting Brussels sprouts, seen in Belgium, gives Roger Bertrand the idea of building a destocker.

The 1990s put stainless steel in the spotlight, and the first electronic weight grader is born at Bertrand. This grader is never marketed, for lack of demand — it was too early.

Only delayed: in 2004, Charles Bertrand markets a vision grader with automatic feeding, also built by Bertrand, which this time enjoys well-deserved success!

New leadership since 2021

In June 2021, Charles Bertrand, who had run Établissements Roger Bertrand since 1996, handed over to Alexandre Bonnat. At 45, after nearly 20 years in industry and further entrepreneurship training at the IAE in Paris, Alexandre was looking to take over an SME in Nouvelle-Aquitaine — and Établissements Bertrand met all his criteria:

« I was looking for a human-sized company, yet large enough to be well structured, with recognised know-how in a niche market, a diversified business and strong growth potential — which was not easy to find, as such gems are rare and much sought after. With its 20 employees in Marennes and 5 in Gujan-Mestras, Bertrand is exactly the company I wanted to lead, and with Charles we hit it off straight away. »
