• Country:
  • Start year:
  • Location:
    Montpellier, France
  • Area Type:
The fish are released in nature once they have reach a safe size.


  • Habitat types: Coastal shallow-water nurseries
  • Keystone species present: Dusky grouper, Sparids, red mullets, etc
  • Fauna (mega) species present: Dusky grouper
  • Fauna species reintroduced: All the species captured, except exotic species


  • Description: This project enables a boost in the resilience of ecosystems around the restocked habitats. It is led on 3 locations (Marseille, Cassis, La Ciotat) and consists of 3 phases based on the lifecycle of coastal fish. The first phase starts with post-larvae capture on the 3 sites with specific light traps (CARE), with samples beeing collected by local fishermen. The second phase is the breeding phase of the collected fish in a special farm, with specific breeding procedures of non-domestication. Finally, restocking at sea takes place near the fishing sites on emancipation habitats suitable for the released and temporarily immersed juveniles.
  • Aim: The aim is to enhance survival rates at the early life stages, facing the highest mortality rates. The colonization of nursery areas is the second most critical phase after the larval stage, with 90% mortality due to predation and the competition. BioRestore aims to lower this threat for fish stocks by increasing the survival rate at this crucial life stage.
  • Vision: BioRestore intends to provide a tool in order to protect early stages of fish from damaged areas such as construction works or polluted locations. This tool could be used easily in different contexts to help the resilience of fish population towards human or natural issues resulting in lacks of nursery habitats for fish.
  • Accomplished in 10 years from now: The aim for the future years is to extend the use of this tool to more locations in the world, being able to specifically target endangered species and to help to enhance the recruitment in these species populations.
  • Uniqueness: The process BioRestore is a unique and has been patented. It has several application domains including rewilding purposes, but also for aquaculture or the aquariology hobby.
  • Results so far: So far, thousands of fish have been restocked and the mortality rate in the farm is very low (between 5 and 10% during the whole breeding phase, regarding all the species) compared with the natural mortality rate (90-99%). Fifty different species have been captured and benefited from the program. Furthermore, another farm has been built and is actually working in Toulon.
  • Flagship species: Other
  • Other characteristics: Research, Sale of sustainable products


  • Inspirational value: As an effective response to the collapse of fish stocks, Ecocean proposes two complementary solutions which both have the same goal: to boost the recruitment and survival of fish: BioRestore® to increase fish population by restocking, and Biohut®, to bring back fish nursery function in places where it has been damaged by built infrastructures (ports, pipelines, seawalls…).
  • Experience you would like to share: We could share our experience about the process in order to target different species and to adapt to new contexts that differs from the Mediterranean. We have the experience of successfully capturing, breeding and restocking a lot of species.
  • Experience you would like to gain: We would like to gain experience about new species and new ecological context in order to improve and expand the process to new areas.
