A comprehensive range of PCC fishing & rearing devices
Here are two general types of post larvae capture devices, namely crest nets and lights traps. Depending of the environment and the objectives of the project, a certain device type will be preferred to another.
The following table published in the CPS review gives some helpful indications regarding choice of device.
|Stream study||Easy Installtion||Diversity species||Unwanted species (low interest)||Stress||Abundance||Cost||Universality||Ergonomics|
|Light trap (other)||4||2||2||2||2||2||3||1||2|
|CARE light trap||4||1||2||1||1||2||2||1||1|
|1 = Excellent ; 2 = Good; 3= Acceptable ; 4 = Poor

The Ecocean team has tested and evaluated all of these devices, but we chose to focus our research and development work on light attractors because they have the huge advantage of being usable in every coastal zone, from tropical to temperate and even to cold. We have therefore gained more than 10 years extensive experience of capturing PCC with this type of gear in over 20 countries. Those fishing devices can also be used in freshwater environment (lacs, bays , rivers…)
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 […]

Ecocean is present all around the world, now also in Korea ! It is the first project of Ecocean in this country, but also the first time Biohut is used in the open-sea! We equipped the pylon of the scientific platform of oceanography KEPCO. The results are promising as we observed young stages of fishes […]
