Snow Day! Snow Day! Snow Day!
The salmon didn't mind and it gave them time for the ammonia levels to stabalize and EMS fish to drop off to a balanced 95(ish) fish left.  (BTW, The DNR says it is a horrible year for EMS with many tanks dropping below normal levels or having 100% die off.)  Students are taking turns feeding them throughout our school day and naming our friends.
Now that they are bigger they just aren't staying still for photos!

Hey friends!  Remember our "Bug Hunt" this fall?  Well, the Clinton River Watershed Council is at it again this Saturday and you are invited!  You'll need a parent to drive you and stay, but if you want to go visit:  http://www.myfoxdetroit.com/story/24474969/foxe-help-ecologists-search-for-stoneflies-in-local-rivers-and-streams  and call to register.

Oh and don't forget to check out the video with Ms. Amanda when you visit the site!

It's a sad week here in the tank--we're struggling with some EMS.  We've had a bit die off each day from the bottom of our tank--sadly it is something that happens with Salmon in a tank.  I learned that some years EMS is more severe than others.  What is EMS?  Well, according to the DNR site:

"EMS is a pathology caused by a vitamin B12 (thiamine) deficiency in the adult salmon.  The adults pass this syndrome on to the eggs and the fry may suffer some mortality as a result.  Symptoms of EMS include spinning and lying on their side on the bottom.  Some portion of your fish may act this way for the first couple weeks after they swim up.  It usually is a small portion (less than 20%).  Once the fry start feeding they will get all they thiamine they need from the food."  
From: https://www.michigan.gov/dnr/0,4570,7-153-10369_50075-191097--,00.html



"What to do if your fish have EMS:  It is unlikely the fish will survive long enough to begin feeding to get the thiamine they need and recover.  You can choose to keep the fish in the tank until they perish or remove them immediately after determining they have the deficiency."

So, what does it look like?
See this fish swimming at odd angles? That's one of our "twisted sisters".

No, they're not dead (yet) they just lay on their side, chilling, and I hope they can feed.  However, when they take off to explore they swim in spirals--kind of difficult to eat food that way.  So, unfortunately, we've had about 20 of our friends who do this die.  We're down to about 150 fish now from our eggs...



Can you spot the fish on these videos that are showing the signs of EMS?

Salmon Scoop

By: Angelique K

Hey guys welcome back to salmon scoop. Boy have the little salmon grew. It’s like just yesterday they were coming into their tank just beginning their new life in the Swartz classroom number 18. As you can see their yolk sacs are now almost gone but are silver and small. They are just adorable! Right, am I right or am I right. HA, just kidding!

Well I got homework I got to go. I’ll see you 
next time on the salmon scoop!


I wonder how many we have--okay, now stay still so we can count you!

Swim! Swim! Swim!

They are all swimming up now--ready to start feeding!
