Our lab was at the Toronto Zoo as part of Science Rendezvous. We had fun talking to kids and adults about the sense of smell of fish! @liamtigert.bsky.social @utscbiology.bsky.social @utscresearch.bsky.social

Had a great time calibrating our @loligo.bsky.social fish swim tunnel today with my MSc student, Gary. Took a couple of tries but got it working! @utscbiology.bsky.social

4) The responses were completely reversible when fish were exposed to normoxic sea water after.

3)The responses to some odorants (L-cysteine) were more affected by hypoxia than the response to others (L-Arginine)

2) mild hypoxia (50%sat) decreased olfaction just as much as more severe hypoxia!

A 🧵 about some interesting findings from our latest paper:
1)external hypoxia not hypoxaemia (internal hypoxia) causes a decrease in olfactory sensitivity in seabream

In the lab 😁 finally getting around to testing a new piece of equipment - LI-COR DIC analyzer. Love the nice peak! This will support our climate change research on fish! @utscbiology.bsky.social @utsc.bsky.social Thank you to CFI for funding to buy this incredible machine!
