The present work deals with the application of an electronic tongue based on potentiometric chemical sensors to the detection of paralytic shellfish toxins (PSTs) in bivalve extracts. PSTs are naturally occurring toxic compounds produced by some phytoplankton species that may accumulate in bivalves during algal blooms. Bivalves for human consumption are therefore monitored for PSTs. Electronic tongue...
This paper presents the design and control of an actuated bivalve robot, which has been developed to study the burrowing locomotion of bivalves in sediment. The setup consists of a tank filled with sand and water, plastic models of bivalve shells capable of expelling water and an external actuation mechanism simulating the rocking burrowing motion typically used by these animals. The realistic shell...
The effect of dredging on the biomass structure of benthic invertebrate communities was examined at 9 sites in the northeastern Baltic Sea during 2002-2007. We analyzed whether and how bottom topography, depth and sediment type contributed to these relationships. In general, the effects of dredging on benthic invertebrates were weak. Dredging clearly increased the biomass of bivalves but the communities...
The present study has the aim of describing the benthic communities settled on the concrete structures of the Senigallia artificial reef (western Adriatic Sea) after ten years by its deployment. The artificial reef is placed 1.5 nm offshore, on a sandy-muddy bottom at a depth of about 12 m, far from natural and artificial hard substrates and it is affected by the Cesano river's inflow. It was deployed...
