Building tomorrow’s fishing

Fishing net manufacturer Le Drezen has recently supplied a purse seine net to Gevred, Compagnie Française du Thon Océanique (CFTO)’s new 77m freezer tuna seiner.

This will be followed in May by a new purse seine that will be delivered to the Pendruc, the second vessel out of CFTO’s nine tuna purse seiners.

The company has announced the launch of an ambitious research program to ‘Build Tomorrow’s Fishing’.

“The idea is to include a sustainable and responsible fisheries logic in our industrial processes, to further increase the useful life of this very complex net by 30%,” said Max Dufour, CEO of Le Drezen. “Our Research & Development is engaged in this strategic and prime project facilitated by the backup of its parent company, WIRECO Worldgroup.

“For nearly a century we have been manufacturing fishing gears. Our work is specific because it takes into account the constraints related to the conditions of fishing at sea, the resource status, the decisions of the captain, as well as the shipowners. Le Drezen has designed more than 300 tuna seines in the world and is now the industry benchmark for the design and development of this type of fishing gear.”

Le Drezen aims to increase the duration of use of these nets by 30%, even though it says that the actual duration is already significantly higher than the other nets on the market. The goal is to further push the tearing point, which the company says is an achievable technological challenge, thanks to the thorough work on materials and plans supplied by 50 years of feedback from tropical tuna fisheries.

Information on vessel horse power and changing modes of propulsion, ocean currents, weather on fishing location, the specific expectations of masters and expertise of captains and crew will all be utilised in the research program. The data will be analysed and Le Drezen will be significantly investing in output from a single digital simulation software, which will be unique in the world.

The company says that the outcome will be the reduction of damage and losses, but also the costs of maintenance and operations for the shipowner. And this cost optimisation goes hand in hand with a policy of promoting sustainable and responsible fishing.

“There are currently more than 500 tuna seiners in the world and only 30% of them buy full seines,” said Mr Dufour. “Owners often assemble them themselves from their own seines which are not technological nets and are more fragile, as they are manufactured by stakeholders who do not have control of the purse seine designer business. We master these two skills: design and industrialisation. Le Drezen invests in net technology because our research on the behaviour of the seine fishing induces specific industrial and technological choices on the net.”

Le Drezen’s fishing gears - whether they are trawls, gillnets, sardine or anchovy purse seines or tuna purse seines – are renowned for being efficient while reducing the amount of damage. They are also claimed to have the greatest longevity on the market.

Le Drezen is also exploring promising markets such as Mexico, Ecuador, North America and China.
