Finally, it has begun!! The rainbow trout are all grown and it’s time to give them a little spin in the swimming respirometer. This girl was understandably pretty shocked about being measured and weighed but she quickly recovered once in the respirometer — the fish is swimming against a certain water flow (here it’s about half a body length per second) and she seemed to immediately realise what to do. My supervisor explained that in earlier experiments with brown trout, the brown trout were more prone to not swimming at all and laying on the net in the back, but rainbow trout are more cooperative and raring to go!
to the tune of harry styles' sweet creature: sea creatures...
some cleaned up sketches from my dedicated class doodles area. the melon of a beluga brings me intense joy i highly recommend drawing a beluga
