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. Keep in mind that phytoplankton in the ocean contribute 50 to 85 percent of the oxygen in Earth’s atmosphere (Ocean, the planet's lung). Surveillance and protection of our shores is fundamental. We must, in real time, be able to inform people of water conditions. This website shows you how we monitor water quality using behavior of oysters and other clams as cleanliness biosensors. 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) and various life history traits 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.

What kind of noise annoys an oyster? This is a very serious question if one think to the problem of noise pollution in the Oceans. In October 2017, it has been addressed in a paper published in PLOS One: The sense of hearing in oyster. But as soon as in 1930 the issue was raised! Listen this song by Frank Crumit "What kind of noise annoys an oyster". Lyrics by Billy Curtis. Enjoy without moderation.
In Copenhagen, from 21-26 June 2014, MolluSCAN eye participated with FRAM to the European Festival SCIENCE IN THE CITY with the exhibition "Arctic knowhow: Talking Clams".
The exhibition "Talking Clams" presents unique and innovative approaches developed by scientists to understand the changing Arctic by studying marine shells.

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

Some interesting and very encouraging statistics about the "Talking Clams" exhibition at Polaria from Geir Stokke, the Managing Director of Polaria.
He estimates that 70.000 visitors visits the "Talking Clams" exhibition per year.
Among the visitors there have been 3000 pupils from schools and about 6000 students have visited the exhibition, some of them especially to see the exhibition.
Some guided tours for groups have included the "Talking Clams" exhibition, especially combined with the exhibition “Our Synthetic World”
Special Family-Sundays with "Talking Clams as theme" have been held and special family-quizzes during Easter and Christmas included questions from the exhibition and had a lot of participants.
