Collecting bottles on the day after the 1st of May at the beach of Baia das Gatas was a big success for us, but unfortunately not for the environment, since we could not carry all the trash from the beach… Additionally, we drafted a letter in which we asked people for collecting empty bottles for us and spread it all over Mindelo, while Paulo contacted many friends and spread the word also in the digital world.
The search for bottles raised some attention about our project so that the local newspaper Inforpress published an article about it and we were invited to Radio Morabeza a local Mindelense radio station and ADECO a consumer representing NGO.
We gave some interviews and talked about the microplastic issue, our project and the GAME programme for students. And during a visit of the OSCM even the president of the Republic of Cabo Verde had a look at our experimental set-up and was very interested in the programme and the topic.
Besides of all these technical, organizational and logistic issues, we went out to the field from time to time to search for our test animals. Since we want to investigate the effects of microplastics on filter feeders and also want to compare these with the effects of natural seston particles, our goal was to find a filter feeding organism that is easy to keep and suited for measurements in a lab study.
But remember, we are almost in the middle of the Atlantic Ocean next to the North Atlantic gyre. This means that the waters around Cabo Verde are quite oligotrophic and therefore not the perfect environment for filter feeders. In the beginning, our search was as hard as the search for bottles, since this species is very small around mm and is very good in hiding in small holes in intertidal rocks.
So far so good: we got our test animals and collected over bottles to convert them into experimental containers. But what about the feeding of our hungry mussels in the lab?
In Kiel we planned to feed our mussels with living microalgae from a lab culture. However, we had some luck and, with some logistic help from Germany, got some nutrients and started a population of unicellular diatoms, which we got from the newly built shrimp farm in Calhau. With the help of neon lights and good hopes we finally got our first batches of microalgae Thalassiosira weissflogii to feed the bivalves in the lab. Now, after two months of preparations and organizations, we got bivalves, a working lab with an algae culture, a seawater filtration system, light and air supply, as well as enough PET bottles for our main experiment.
Therefore, we started our pilot studies these days with 65 test individuals of Brachidontes puniceus. The pilot studies will provide us some information about the main experiment.
