TO UNDERSTAND AND EDUCATE
Now more than ever, protection of the environment is a top priority

     Protection of our environment is an absolute priority: this is particularly true for aquatic environments and especially so for coastal waters. In 1994, an estimated 37% of the global population lived within 60 km of the coast and it is thought that this will increase to more than 80% by 2050.

     Today, 80% of water pollution comes from activities on the land and it is clear how susceptible our coastal waters are to this pollution. Surveillance and protection of our shores is fundamental. We must, in real time, be able to inform people of water conditions. Our technology at a glance.

     The ability of clams to permanently ‘taste’ their environment is one of the possible ways to monitor the quality of our coastal waters. Monitoring 24/7 their natural opening/closing activity, how fast they switch to a resting state ("fall asleep"), how they follow biological rhythms (as a function of day/night alternation and/or tides), monitoring their growth rates and if they spawn at the right period is also a fantastic "thermometer" which allows to read throughout the year - just like a doctor who perform diagnosis - the health of both the clams and the ecosystem where they live and interact.

HFNI valvometry (High Frequency, Non Invasive), what is it ?

 

 

 

 

Freshwater clams Corbicula fluminea. Very accelerated speed ! In lakes or streams, they reproduce too much but otherwise they are very quiet

A tool to record mollusc bivalve activity...

... enables us to study their behavior (ethology) in their natural habitat and constantly monitor water quality (bioindicator)...

... when faced with stress, a pollutant, valves can suddenly close or express abnormal movements indicating a change in water quality. Following extreme situations , the animal die and their valves remain open and motionless ... Intermediate cases, their biological rhythms are altered (chronobiology)

 

 

 

 

 

Oysters, Crassostrea gigas, equipped with HFNI   electrodes, in a traditional oyster bag 

...a continuous on-line recording...

the distance between valves is continuously recorded using light-weight electrodes that allow even free ranging bivalve species to move their valves without experimental constraints. So we have direct insights, 24/7, all year round, into the behaviour of bivalves in their natural environment (ethology). A short paper to find out more.

Exhibition Talking clams. Since November 16th 2012, MolluSCAN Eye presents its Arctic activities in the especially original architecture of the museum POLARIA in Tromso, Norway

Clams living on the sea bottoms are becoming an important tool in providing records of environmental changes. Come and see what clams are telling us about their life and how scientists manage to understand them.

MolluSCAN eye is supported by Aquitaine Science Transfert, the French society whose aim is to accelerate the transfert of technology from lab to public in Aquitaine (South Western France).
