How to improve rearing conditions of salmon to re-stock natural populations
Petra Rodewald is currently defending her PhD thesis at the University
of Helsinki. The thesis aims at improving rearing and release methods of
salmons to improve the success of introduction of farmed salmon to
re-stock natural stocks.

Bye-bye lab fish!
Re-post 10.2012
I just completed my experiment with Diplostomum sp. parasites and lab-reared sticklebacks. I took care of the fish during the last two years. A bit sad this period of my life ended but released it is over :)
Some nice pics of these spiny stuffs:

The game starts now

Now that I have got the Lymnea snails infected with the right species of parasites, I can make experimental infections of fish for my experiments. Let's start this!

Looking for infected snails...
Re-post 07.2012
Looking for snails infected with diplostomid trematodes around Helsinki is fun!
The aquatic snails are individually placed in buckets and exposed to strong light to trigger the emergence of cercariae larvae of the parasite (upper left picture). Snail mucus is then collected and screened for parasites under the microscope (bottow right picture - the kind of white stripes).
Halloween with the lab!

At the entrance of a Halloween party with my lab - geek gathering - great time :)

Have I seen enough sticklebacks in my life already?
Re-post 8.2011
I have spent so much time looking for the parasites of sticklebacks under the microscope that every time I am asked to draw something, the first thing coming is a stickleback...My contribution to the night of arts 2011...
Can sticklebacks indicate water quality?
Re-post 07.2011
On the photo: massive deaths of sticklebacks due to pollution at Rauma - Finland.
It has recently been proposed that this fish could be used as indicator of water quality. For instance, heavy metals can accumulate in the body and alter physiological functions. The accumulation of metals in the fish is measurable and could be used to monitor pollution.
