Call for abstracts and presentations.

The International River Conference: “Restoring floodplains, habitats and connectivity by using mussels and brains” is open for registration. There is still room for additional presentations.

Conferences objectives are to highlight experiences and results from a wide range of European river restoration projects and rehabilitation of species of freshwater mussels and fish.

The Conference will be held in Lund at the traditional Grand Hotel (28-29 September) and participants are welcome to join us for a field excursion (30 September, free of charge) to rivers where major floodplain restoration efforts have been made. In addition, the mussel rearing facility at the Hemmestorp Mill will be at display.

Written by Ivan on . Posted in BOB'S BLOG, Re-introduction of Unio crassus, The thick shelled river mussel

Mussels are filterfeeders, which means they have to filter water to get nutrients. They take up nutrients through so-called detritus (dead organic matter from animals and plants), algae and dissolved particles in the water. During the summer we carried out a feeding experiment at Hemmerstorpsmölla where different types of food combinations were tested in order to find out what is most suitable for juvenile mussels. The mussels were fed with detritus from the stream, and combinations of detritus with algae and/or proteins. As control group acted a treatment where the mussels were fed no detritus. The survival and growth of the 880 juveniles were measured every second week.

The juveniles come from Bråån, a stream where there is a healthy mussel population of the thick-shelled river mussel (Unio crassus). We cultivated those mussels in the lab with the help of their host-fish: minnows (Phoxinus phoxinus). At the beginning of the experiment the juveniles were only 220-240 µm big, while now they are more than double the size: which means they are now over half a millimeter big! The results also suggest that it is most likely detritus that is the most important source of food for our mussels.

Now the juveniles get their favorite dish served until end of September when they will be placed out in the different streams that are part of the UC4LIFE+ project.
