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.
DISCOVER OUR LATEST NEWS IN VIDEO! As every quarter, Ecocean broadcasts these episodes retracing the last months of his teams! Let’s go to Ajaccio, in southern Corsica, for the coastal fair organized by @ Ideal knowledge. Gilles Lecaillon, CEO of Ecocean, presents this new Newsvideo and therefore the latest news from our team. First of […]
Ecocean integrates a network for wildlife! “Our Mission: We want to make Europe a wilder place, with more space for wilderness, wildlife and natural processes.” By bringing life back, we will continue to explore new ways of enjoy and make a living in a fair way ” The aim of the network is to recreate […]
More animals on the water! This week in Paris was inaugurated the first floating raft planted on the Canal Saint-Martin. the goal is to increase the number of animals on Parisian water! Terrestrial plants that will attract insects above and Biohut that will attract fish underneath! A raft of 40m2 was installed in February on […]
A floating farm !? what’s this ? As its name suggests, it’s a farm, with cows, that produce good organic milk … but on the water! And of course we have installed #Biohut! It is located in the heart of the port of Rotterdam! Last week, Ecocean was able to equip 4 Biohut and 2 […]
A report on our farm in Marseille, on Al-Jazeera at Port de Marseille-Fos. As a bonus, spotlight on two of our fishermen in the video. #Biodiversity #Restocking #Fish #Mediterranean
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 […]
