Biohut®

The life cycle of coastal marine species is based on key steps: after laying in full water, the eggs drift according to currents, become larvae, then post-larves that instinctively join the coasts. To this crucial stage, these young fish require nursery habitat to provide food and protection from predation. Even in an optimal environment, their mortality rate is naturally high (about 90%). However, the scarcity of natural habitats due to the artificialisation of coastal areas may lead to the total disappearance of juveniles in certain areas. Restoring these habitats is therefore a key issue to maintain fish populations and, more broadly, balance of marine ecosystems.

A true refuge for young aquatic animals from the early stages of life, it simultaneously offers a protection zone (empty modules) and suitable food sources (module filled with complex shell substrate that helps establish a food chain).

Biohut® works in both marine and freshwater environments. Easy to install, it is composed of 100% recycled and recyclable material, made in France and labeled "Origine France Garantie".

Founded on sound scientific evidence, Biohut combines simplicity, efficiency and sustainability.

We support you at every stage of the Biohut project: from installation and module maintenance, including ecological monitoring of local species, through to end-of-life management of the modules.
