Water quality tests were done at recess today, and since there is elevated nitrites, I need to add more of the Nitrifying Bacteria. However, afterschool, students will be doing a 4 gallon water change to help combat the increase in nitrates and nitrites.​

01/02/20- I removed 7 dead trout fry from the tank, most of whom had been sucked near the filter, and released the rest of the trout fry still in the basket into the rest of the tank. There was one dead fry in the basket.

12/27/19- I came into school on Friday morning to check on the trout and give them 0.7 grams of size 1 food. Many of the trout had left the basket, but some remained. I didn't see any dead fish yet.

12/17/19- 4 dead trout fry were removed. I've noticed that the fish that have died look like they haven't been eating. Many of the fish that are lively in the tank are developing a bit of a belly (fat storage). This means I'm probably feeding the fish more than they need, but this will help them survive Christmas break when I'm not feeding them everyday.

12/20/19-​Fish waste was removed using a pipette.  I released some of the more active fish into the rest of the tank, but I'm keeping the less mobile fry in the basket. I did a 2 gallon water change after releasing the fish because I noticed a build up of some bacteria at the bottom. 10 mL of Nitrifying Bacteria was added after the water change. 0.5 grams of size 1 food was fed to the trout. 

 12/9/19- 12 dead fry were removed. 0.7 grams of size 0/size 1 food were fed. A bunch of fish waste was removed using a pipette.

12/13/19- 1 dead fry was removed. 0.7 grams of size 0/1 food was fed. A bunch of fish waste was removed using a pipette. I also removed the cover of the filter intake since it had collected a bunch of small fish food/waste that escaped the trout basket.

12/2/19-7 trout fry were removed. 0.5 grams of size 0 food was given to the trout. I used a pipette to remove fish waste. I noticed that one of the fry that was removed had just the head and a small amount of spine. It appeared that a fish had eaten its tail...(see picture below)

Since there was an early dismissal today due to snow, and because I wanted to take precautionary measures in case the power goes out at school, a student helped me change out 3 gallons of trout tank water with clean water. 5 mL of Nitrifying bacteria was also added.
12/3/19- 3 trout fry were removed. 0.5 grams of size 0 food were fed to the trout. I tested the ammonia levels and it was a solid 0.5 ppm.

12/5/19-9 trout fry were removed.  I used a pipette to remove fish waste. 0.7 grams of size 0 and size 1 food (half and half) were fed to the trout. Since the fish are approaching 1 inch in length (the ones that died were 0.75 inches), they are ready to begin eating the larger size food. However, since there are a few smaller trout fry, I still have some size 0 food in there.

12/6/19- I removed a bunch of trout waste from the basket. 10 dead fry were removed. 0.6 grams of size 0 and size 1 food were fed to the trout. After a few hours passed after feeding, I noticed that there was a lot of the size 1 food uneaten at the bottom of the basket. This was removed in the afternoon.

The Trout Club did a 4 gallon water change because the ammonia levels were beginning to rise. 5 mL of Nitrifying Bacteria was added (which is necessary whenever I do a water change.)

11/25/19- 1 dead fry was removed (see picture below). Fish waste was removed from the basket. 0.5 grams of size 0 food was fed to the trout.

11/26/19- 1 dead fry was removed. A student used a pipette to remove fish waste. 0.5 grams of size 0 food was fed to the trout. I removed the cover to the filter intake and washed off the waste that had collected on it. I'm hoping this will help improve the water quality since it appears some of the fish food was getting sucked into it.
11/27/19- 4 dead fry were removed. A student used a pipette to remove fish waste. 0.5 grams of size 0 food was fed to the trout.

Below is a picture of the fry that was removed on 11/25/19. You can see that it did not completely absorb its yolk sac, as there is a bit of an air bubble that can be viewed on the picture to the left. This was also a fry that was not eating, so its cause of death would be starvation.

11/18/19- I fed 0.3 grams of size 0 food to the trout.
11/19/19- I fed 0.3 grams of size 0 food to the trout. I used a pipette to remove some of the fish waste that gathered at the bottom of the basket. This is how you know the fish are eating and digesting!
11/20/19- I fed 0.5 grams of size 0 food to the trout. I used a pipette to remove some of the fish waste that gathered at the bottom of the basket. 
11/21/19- N/A

Now that the trout have absorbed and eaten the food in their yolk-sacs, they are no longer "sac-fry," but are just called "fry." Once they begin to develop lines on their bodies and approach 1 inch in length, they will be called fingerlings.

11/11/19- Some of the trout began swimming to the surface! In a few days, when more trout are swimming to the surface, we will begin feeding them!
11/12/19- No change.
11/13/19-  A dash of size 0 food was put into the water, but I didn't see any trout eat it.
11/14/19- 10 mL of Special Blend was added to the tank as maintenance. A dash of size 0 food was put into the water, and it looks like a few trout are beginning to eat. Check out the video below!
11/15/19- A dash of size 0 food was put into the water.
