Our Chinook Salmon are about 3 inches in length. Their black and grayish stripes are blending in nicely with their environment. Theses Chinook Salmon are very active reminding me of how a 3 or 4 year old behaves. The water in the tank has gone up by one degree reading at 54 degrees. The water in the tank is very clean due to our weekly cleanings. Its been fun watching our salmon grow and development. Our anticipated release date is May 31st.  As the days go by I see more and more students getting involved with this Salmon in the Classroom project.  The food size has increased to 1.5 mm fish pellets. The fish are fed over three times a day now and the fish are roughly 3.0 inches in length. The fish pellets smell like fish and steamed greens.

Our Chinook King Salmon are doing great. They’ve grown a lot since the last time I posted about them.
They’re getting their Camouflage AKA their stripes that will help them when they are  in the wild. We also moved their food to the next size of pellets. The temperature of the tank is right around normal at 53 Degrees.
We are still at 155 Chinook King Salmon, we haven’t had any losses. The water was cleaned today and looks very clean and clear. They’re still in swim up fry stage and looking to be very active. That’s all until next week. Thanks for checking up with our Chinook King Salmon.

Salmon In the Classroom 2/24/2014

The water in the salmon tank is very clear today. The weekly cleanings have been working well to keep the tank nice and clean.  Our salmon are in the swim up fry stage. The salmon look healthy and they seem to be staying very active.  They are about an inch long now.  The temperature of the tank is 50 degrees which is right where we want it. I estimate we have about a 155 Chinook King Salmon. I will keep up with the updates and hopefully everyone reading this is as excited to learn about the salmon in the classroom as I am to be writing about it. Enjoy reading about our growing salmon.

Salmon In The Classroom Blog 1.11.2013


   At Duck Creek Learning Center, We have started a project called “Salmon in the Classroom”. Salmon in the Classroom is a real life science activity to get students involved in raising, care and maintaining the salmon in the classroom from fall until spring. We start out getting fertilized salmon eggs from the Department of Natural Resources (DNR), where we raise and feed them until they reach fingerling stage.
   Our salmon start out in the EGG stage and will stay in this stage depending on the water temperature; it will take between 6 to 12 weeks to hatch. In this stage you will start to see tiny black spots on the eggs, which are called eyed eggs.
   Next stage is called ALEVIN, which are newly hatched salmon, which have an attached yolk sac that they feed on for nourishment. Nourishment from the yolk sacs lasts up to several weeks. When they start to emerge into the FRY stage, where our salmon are currently at.
   In the FRY stage we start to feed the salmon little by little. The food we feed the salmon look like finely ground coffee, but it’s not. It consists of byproduct of fish, and composite of vitamin.  We will continue to feed the salmon the finely ground food for 2 weeks, until they get longer than 1 inch.
  At the moment we have 190 fry salmon and 10 losses since we've started. The temperature of the fish tank is at a steady 48 degrees, just how it would be in the wild. We have two sets of conjoined twins, where they are conjoined at the still remaining yolk sac.

WLACE Release 2012

May, 25, 2012

Students from Duck Creek released approximately 45-60 salmon par averaging 3-5 inches in length.  In addition to releasing the fish, students were involved in water quality activities.  The fish were released near Baldwin, MI in the Pere Marquette River.

Salmon fry
Does the water look murky or clear? Well, the water is really clear. The temperature of the tank is about 50 degrees. The ph Level of the water is at 7.6, which is really good. The physical features of the salmon are that they are very big and colorful. The salmon are eating really well;  the majority of the salmon eat from the surface, sub-surface, and the bottom. The average size of the salmon is a about an inch and a half. There are about 85 to 90 salmon left in the tank. The special features I have seen are the Siamese twins, they are still alive which is great and really surprising.

MY Opinion on the Salmon Fry in the Classroom 
My opinion on the Salmon Fry, well I love learning new things and so I took this class and it is fun and I have learned a lot about the salmon. When I started this class I thought it was going to be boring, but I got into it and now I love it and I don’t want to stop learning about salmon. This class is such an adventure so much to explore and learn. Well, we have had the fish for about five months now and we had them since they were eggs and now they are fish, which is sweet watching them get bigger.  Feeding them is the best because they are so jumpy and happy for the food. We started off with about 300 fish and now we have about 100 fish and they are doing well. We have the first Siamese fish that have survived after being hatched. The temperature of the fish tank is always at 49 or 50 degrees because the salmon are fresh water fish and they are cold blooded.  We clean the fish tank about once or twice a week. The tank has to be clean or the fish will die off. We do PH levels, which are the measurements of the acidic level or basic quality of water. PH scales ranges from a value of 0 (very acidic) to 14 (very basic), with 7 being neutral. Our tank is at a PH level of 7.4 which is really good.
