Trout Need Cold, Clean Water!

 The students were eager to help test the water to make sure it keeps our trout safe and healthy. We monitor the water quality  two times a week. The students help by counting the drops of each test solution and assisting in determining which color matches the  test card indicating the level.

 

These were the results we found... ph 7.4, nitrites 0 ppm, ammonia 0 ppm, and nitrates 0 ppm. Looks great so far! As the trout grow, we can expect to see some changes. The students love to see the colors change! They mostly learn that trout need clean water through this and that we can help to keep the water clean for them both in our tank and in the streams!

 

 

All the eggs have hatched and I have been

hesitant to post, but are doing well so far! We had 279 trout last week, but have lost a few over the week. Tuesday morning began with a bit of excitement! When I checked the tank in the morning, the temperature read 59.7 degrees which is outside of my comfortable parameters of 42-55 degrees. At first I thought my eyes were surely not seeing it correctly, but a touch of the water in the tank confirmed it was too warm. The chiller had been accumulating ice off and on since last year. I guess I was just hoping it would keep working...needless to say it did not. Thankfully, Larry Winey from Penns Creeks TU had a backup chiller which he brought to the school immediately. We switched the old chiller out and placed the new one in and began to slowly adjust the temperature as to not shock the trout! Yikes... yes, the students have learned through this that the trout need COLD water! Thankfully, we only lost three alevin through this event!

 

 The students wait patiently to get a peek at the changes!

 

 

     Below you can see the alevin also called sac fry because of the yolk sac that feeds them during this stage of their life cycle! At this point they appear almost dead, until we get too close. Then they scamper to hid under each other. They will remain in the yolk sac stage for approximately 2 weeks. Then the yolk sac will be absorbed which is called  "buttoning-up". At that point they will start to swim looking for food. The students are eager for this stage...they are worried about them now. I assure them they are just fine- "fat and happy"- no need to move around when all you need is being provided!

To date we have 265 alevin and the chiller is keeping the tank just right...this experience is never the same! Each year there is a new challenge and a never ending learning experience. Before long we will begin our trout book project. The students are gaining valuable background knowledge and eager to write.

Eggcitement!

 The smiles on their faces tell the story! I love seeing students excited about learning at school. That is one of the main reasons I love this program. Today we received the second batch of brook trout eggs for our Trout in the Classroom Program. This batch was lovingly hand picked by our coordinator. There was a notable difference in this shipment. There was only 1 dead egg. I placed 179 eggs into another basket in our tank following the same procedure described yesterday. I placed the cover over the tank to help them settle in peacefully. Hopefully, they will hatch over the next few days without incident. If all goes well each student will be able to place their own trout into the stream on May 15, 2014. Wish me luck!

The Journey Begins!

 The eggs are shipped by UPS from Bellefonte.  When they arrive,  I take a temperature reading of the water in the shipment bag. Then I place the bag in the tank to allow the eggs to acclimate to the tank temperature.  Next, I must separate the dead eggs from the living eggs and keep a count of both. I use the turkey baster, a plastic spoon, and a pipette to remove the dead eggs. I have two containers. One is for dead eggs and one is filled with water from the tank for living eggs. Once I have twenty living eggs, I place them immediately in the tank.

 

I continue this process until all living eggs are placed peacefully in the hatching  baskets we made.

 This year we placed 202 living eggs between two hatching baskets.  I removed 42 dead eggs from the shipment. As a result of the difficulties last year, we are keeping the tank temperature a little warmer in an attempt to allow the eggs to develop more quickly to allow more time for feeding before Christmas break.

     I was concerned because  a lot of the eggs had streaks of blood and began to die over the next few days. All the eggs hatched, but  about half of the alevin also had streaks of blood and then died. We lost around 100 fish since their arrival which began to concern the students. After speaking with some of the other teachers at our in-service day, I  soon learned we were not alone. Today, I received a call from our TIC coordinator who informed me we would be receiving another shipment of eggs. They had tried a new way of sorting the eggs this year using a machine to separate the dead eggs from the living eggs. She felt it stressed the trout causing them to die because the eggs that were sorted this way were the ones with the most deaths. It is a learning process for all. She hand picked us another batch of trout eggs due to arrive either tomorrow or Thursday! Check back to see how we make out!

 

 On a positive note, we planted seeds several weeks ago that had not shown any signs of life until I began placing the dead trout eggs/alevin in the soil. Apparently the Indians had a great idea because the seeds began to sprout!  I am always trying to find the positive things to keep me going.  

Mrs. Winey! Are the trout here yet?

On Tuesday November 5, 2013 I answered this question over 200 times throughout the day. In an attempt to make the arrival of our trout eggs a teachable moment, I thought we would incorporate a lesson on how punctuation helps us understand how to read with expression. I intended to introduce the  question mark and the exclamation mark and place a sign on the trout tank letting the whole school know that our trout eggs had indeed arrived. The students colored the words and the punctuation marks  for the

sign in groups. Then we place the words and punctuation marks in order to make the sentence and response,
Mrs. Winey! Are the trout here yet? Yes!

We discussed how the exclamation marks help the readers know we are excited and the question mark indicates asking a question. One of my students raised his hand and said he thought the question mark should go after my name  because they are asking me and the exclamation point after are the trout here yet because they are excited and want to know now.
Because the students often call my name in an
asking tone, I decided to go with it even if it
is not completely grammatically correct and teach them that the punctuation marks can change the way a sentence is read. We practiced reading it both ways and the students decided they wanted the question mark after my name and the exclamation mark to show they were excited. It definitely was a better expression of  how we wanted the sentence to be read. I did tell the students that to be grammatically correct we should use the question mark after are the trout here yet.
