The bony fish life cycle involves an oceanic dispersal phase, suggesting significant marine biodiversity at the larval stage. This oceanic phase allows a species to colonize new habitats and promote connectivity between populations, and therefore contributes to the preservation of the species.
individuals become active (phase of competence), and move to their coastal habitats to settle permanently during the nights around the new moon (colonization phase). During this colonization, very high mortality occurs. It is estimated that over 95% of post-larvae disappear at the time of arrival at the coastal habitat, due to high predation, pollution, physiological changes and habitat degradation, thus reducing biodiversity.
Some crustaceans (some shrimp, lobsters and crabs) and some cephalopods (octopus and cuttlefish) have a similar life cycle and are regularly caught in our fishing gear. Finally, multitudes of diverse and varied zooplankton (copepods, mysids, worms, isopods, etc.) are also captured alive.
This tool seems to be adapted to the study of freshwater biodiversity.
PCC is an excellent tool to study and understand this little-known part of the life cycle of coastal marine species. Thanks to Ecocean’s automation of the post larvae capture processes, complete with timing devices if needed, PCC can be used in any marine environment for research & monitoring of planktonic biodiversity.

This week, 4 Biohut were installed in the Port of Rotterdam. This is a test phase to validate the efficiency of the process in this very special environment: the Port of Rotterdam is the largest commercial port in Europe and the eighth in the world in terms of traffic. Located in the North Sea at […]
Here are the last photos from the floating vegetalized raft implemented on the Serre-Ponçon Lake for 6 months now. Juveniles of perch and pike were observed around our Biohut and in the aquatic vegetation. You can also observe the evolution of the terrestrial vegetation of the Biohut in the middle of an exceptional setting! Thanks again to […]
16 Biohut have been installed yesterday in Port de l’Arsenal in Paris, half of them displaying a new design meant to specifically provide spawning grounds for fish to lay their eggs. Ecological monitoring will be lead conjointly by Ecocean and Paris municipality canal department. The excellent visibility allowed our photographer Remy Dubas to take some […]
In 2016, four Biohut were attached to the bank of a floating garden in the middle of Rotterdam. After one year of installation, a diver from Ecocean went to see what species were to be found in our first dutch artificial nurseries. Despite having only 20 cm of visibility, he was able to observe several […]
The UROS project, which aims to restore the spawning and nursery areas functions in alpine lakes undergoing high artificial tidal range, is in its start-up phase. Last Friday Gilles Lecaillon, Sébastien Fonbonne and our project partners from the IRSTEA / ONEMA cluster of Aix en Provence and the Alpine National Botanical Conservatory were on Lake […]
BioRestore®: It is a comprehensive process of post-larval capture, culture, rearing and restocking on temporary habitats.
“In 2014 the National Aquarium (Aquarium) was introduced to a French based company Ecocean and their Biohut technology. Soon after, the newly found partnership led to the launch of a Biohut Pilot Project in the Inner Harbor of Baltimore, Maryland (United States). This was a first for the Aquarium, launching artificial oyster reef habitat within […]
