Here’s the menu!

Just had dinner and you’re still hungry? Want some leftovers? Well if you can answer ‘yes’ to both of those questions, you might be a scavenger... Good for you, we’re going to be focused on that topic for the next 10 days, we are Team 8, the ScAvengers of the IMBRSea Joint School 2018. So we’ll probably be able to tell you more about your condition at the end of our research..

Our project’s aim is to characterise the scavenging activity in the Bay of Tjärnö, Sweden. For this, we are based at the beautiful Sven Loven Marine Centre. Collecting and preparing the equipment we need will for sure be a great opportunity for us to express our creativity and inventiveness (pictures are coming...).
We are now three days into the joint school. The first day of work was dedicated to extreme brainstorming about what to do, the experimental design, what type of work we wanted to carry out and so on. It was very intense. We made up our minds on the way to set the baits in the water to discover what organisms are interested in our dead mackerels, and to see how fast they are at scavenging this marvelous smelly food. We will perform the experiment in two different types of habitats.
Then came the time to actually try to build the equipment we imagined... As said: imagination and creativity were keys here. Here you can see the different versions of the built photo quadrat:



Here you can see the three different prototypes, including our final masterpiece.

We spent an awful lot of time sewing small mesh nets on existing cages to create our traps.



As it is 2018, women are the ones in charge and men execute orders. Just kidding, this picture shows you Megalo Don, TurtleWoman and Lobo do Mar working on the traps.



...While Captain Penguin creates a quadrat with better colours than the old ones.

We were really lucky to get Margarida, “the Super Chef” as our supervisor as she has been greatly helpful during this building and handiwork day. She was able to scavenge the crucial tools and materials needed to build the cages and traps which we are going to use to capture those hungry scavengers of the sea, feeding on our beloved and most vulnerable (well, they’re dead..) mackerels.
Brave Iron Whale and Lady Porpoise dedicated their bodies for science’s sake and went into the abyssal plains (1.5 m..) to test the photo quadrats, the visibility and ultimately the quality of the pictures.

Before starting our actual experiment, we tested our traps in order to have an idea of the scavengers species living in the unfathomable waters of Tjärnö Bay and to determine how fast the carrion is degraded. We therefore put fish into our trap to observe the scavenger activity. Large chunks were already missing after only a few hours.

Now that we know that our quadrats are functional and now that our traps and cages are built, we will proceed with carrying out the actual experiment during the coming days. Hopefully everything goes well... Ahah, no we can’t kid ourselves that way.. But we have good hope that our fully functional and inventive team, along with our Super Chef, are going to overcome the problems that are bound to arise.

IMBRSea Summer School embarks in Tjärnö

The International Master of Science in Marine Biological Resources (IMBRSea - www.imbrsea.eu ), this year organizes the first summer schools at the Tjärnö Marine Laboratory in Sweden. From 1 till 11 August 39 students and 10 teachers are working on seven challenging research projects. Follow the adventures of the seven research teams in the coming weeks via this blog!

Sampling Tjärnö Bay

Professor Karim and Lucy after our last deployment, hurray!! Our experiments are finally finished! We were able to deploy BRUV (see our Finding Fish in Tjärnö Bay post for a description :) ) at all of our sampling locations, plus a few bonus ones. We sampled three different habitat types: sandy, muddy/algae, and harbour areas. Map of Tjärnö Bay with our sampling locations At all of our habitats we sampled at a depth of approximately 1.5 meters to assess what animals are typically found in the littoral zone of Tjärnö Bay - the littoral zone is the region of the sea closest to the shoreline. On our final day of sampling we decided to do a few extra deployments at 10 meters to search for species we didn’t find at shallower depths. We’re working on analyzing all our video footage now - stay tuned for an upcoming creature feature post!

Goodbye my BRUVver, Goodbye my friend

Just a few hours are left of the summer school, the report is done, presentation complete, video shown (to mixed reviews…philistines). We’ve had an incredible time here in Sweden and have learned a lot, about fish, BRUV devices, and ourselves… One of the many beautiful sunsets of Tjärnö Surprisingly our experiments worked out well, we discovered that the most complex habitats did indeed have the most fish. They like structures and hiding places, but not as much as they like mussels…which is why we managed to actually see them on the video! We watched many clips like this screenshot to count so many fish Thank you for keeping up with Team eFISHency over the past 10 days! We’ve enjoyed every moment (well mostly…), and are really happy with our work! xoxo Gossip Pearl
