did you know we had ~80 huge sturgeon die this year (that we know of) in 2
BC rivers? These deaths occurred during the summer when the sockeye salmon were returning
sturgeon eat many salmon at once, and this may be overloading their metabolic capacity during hot summers 😱

releasing these huuuuge sturgeon and watching them swim away is the best part of my job 🫶🏼
another week in the field complete, and one step closer to finding out what is harming these ancient fish 🧪👩🏻🔬🌎🌐🦑

the last 2 years i’ve been investigating why these giant fish are dying across BC
and i’ve started to identify the stressors that could be driving mortality!!

ive spent the last 2 yrs investigating what is killing BC white sturgeon
unfortunately, these deaths continue & we’ve had over 50 adult sturgeon die in the fraser river in the last ~6 weeks
every fish i sample is another step closer to solving the mystery🧪👩🏻🔬🌎🌐

out of pure rage for the obliteration of science funding i made a sticker
cuts are disproportionately impacting EC scientists & women~particularly Black women and women of color
25% of proceeds will go to @standupforscience.bsky.social to keep fighting! 🧪👩🏻🔬🌎

literally the cutest creature to ever exist but unfortunately we have less and less of them in BC
with juvenile recruitment issues it’s always so awesome to find lil untagged bbs - this trip 5/14 of our sturgeon were untagged!

did you know there are 8 sturgeon species in N. America?
spread across the continent, they are found in rivers, estuaries & the sea
i made stickers for each sturgie that lives here, so you can always have your fave fish with you

did you know that some sturgeon make very long spawning migrations? Similar to salmon, some species of sturgeon migrate hundreds of miles from the sea to rivers to spawn
after navigating a long journey once they are in freshwater they will release millions of eggs! 🧪👩🏻🔬🌎🌐

just finished @skypeascientist.bsky.social with a 6th grade classroom!! It was so much fun and the students had excellent sturgeon questions!!

not only are the sturgeon in the Nechako river facing no babies, the last few years there have been unexplained mortality events in the large adults 😩 (typically at the end of summer)
Im investigating what may be causing these mortalities and the role of climate warming 🧐

because there are no larvae surviving in the Nechako river, the mandated hatchery releases 2 y.o. sturgeon to increase the population
it took trial & error in deciding what size to release sturgeon, turns out small sturgeon are otter snacks 🦦
