The gift of a Clean Filter!


As part of our action plan we are completing a 30% (16.5 gallons)water change this morning and another 10% water change in the afternoon. Hopefully this will cut the HIGH LEVELS of Nitrites.


Carefully syphoning the water... don't want to suck up any trout friends.

We accidentally put the filter back together wrong.... it got stuck. We fixed it though.




We cleaned the filter with fresh spring water.

WARNING! WARNING! NITRATES & NITRITES ARE DANGEROUSLY HIGH!!!




As you can see from the picture of this test, our nitrate level is extremely high.



The fishes waste produces ammonia. Our filter has good bacteria in it to decrease the level of ammonia, but when there is to much ammonia the bacteria turns it into nitrates and nitrites. See the Nitrogen Cycle below.

The nitrate and nitrite count should be close to 0ppms but it is .5-1.0ppms which is dangerously high.

From http://www.freshwateraquarium.about.com/:

"High nitrate levels are especially harmful to fry and young fish, and will affect their growth. Furthermore, conditions that cause elevated nitrates often cause decreased oxygen levels, which further stress the fish."


Plan of Action:

  • Tomorrow we are going to do a 40% water change (THE MOST WE HAVE EVER DONE).
  • Get some freshwater aquatic plants-live plants use nitrites and help keep nitrates in check.
  • We could have been feeding them a little too much because overfeeding is a major factor of increasing waste. We will now be monitoring the food intake even more diligently!
  • We are going to do a full clean of the filter before our winter break.

OPEN HOUSE

Today we had Open House. Open houes is when all of our parents come to the watershed classroom to see what we have learned. There were many presentations and it was a fun and exciting expeirience. The Trout presentation went first, and we showed the parents and siblings there the website and what we were doing for the grant project and what we learned about the trout. We talked about the Lexus Eco Challenge and we even sang a song!

Here are the lyrics:

We're watershed experts here at our school were ichthiologists too!!!

Pavlov's Trout


We have decided to test the intelligence of our trout as a side experiment. Before we feed them we will gently tap on top of the tank 3 times. This experiment is modeled after Pavlov and his conditioned dog. Our hypothosis is that after a period of time when we tap the top of the tank they will be conditioned to swim to the surface to eat their food. Hopefully this will reduce excess food falling to the bottom of the tank.

Major Clean Out!!!


Today Mrs. Agner used a syphon (a water vaccum) to take the debri out of the water. We use the syphon daily. She removed 4 dead trout and 2 with spine deformations. We did a water change today of 15 gallons, usually we change 5 gallons per day. We also cleaned the filter and replaced the nylon on the filter. We did this because we felt they have proven their hardiness and are ready to handle a major distruption like this. We began this process in preporation for winter break.



Graduation from the net!



All of our little trout have swam out of the net and all of them have officially become swim up fry! 6 trout with deformed spines were left; we fed them to our stream table lab (home to our black nose dace and crayfish). This is may seem sad, but we wanted to make sure that their life wasn't in vain so they became part of our steam table food chain (survival of the fittest!!)
YUM!

PART 1: WHAT’S THE ENVIRONMENTAL ISSUE?

Our group TEAM TROUT have planned to restore the Pennsylvania State fish, the Brook Trout to our local Darby Creek Watershed. Since our 7th grade integrated learning program monitors water quality and participates in several community action restoration projects, we have realized the importance of restoring wildlife, and recently the native Brook Trout to our waterways. Brook trout are extremely important to the eco-system in our Watershed. They are an indicator species who have been declining in population numbers due to habitat loss and destruction. Non-native trout species have been taking over the Brook trout’s waterways and the Brook trout population is suffering. We will raise our young trout in the classroom to the crucial fingerling stage of life – this will ensure a better chance of survival. As part of our release plan, we will work to restore local creeks and streams including the Darby Creek, a major waterway in our Watershed. Focusing our restoration efforts on the riparian zone and channel characteristics will help us to provide a clean and healthy habitat to release our trout in. By releasing the Brook Trout into a safe environment, we hope to kick-start the eco-system in our very own Watershed. As always it will be important to us to share what we are doing with the community.
We chose the Trout in the Classroom project after hearing a presentation by a second grade teacher in our district. He had attended a Trout in the Classroom teacher’s workshop and he asked our class if we would be interested in the project. We maintain a stream table and a creek lab in our classroom. The idea of receiving 300 trout eggs from PA Fish and Wildlife to raise and release appealed to our group because we value clean water and work to restore habitat and improve the riparian corridor in our own Darby Creek Watershed.




PART 2: WHAT’S YOUR PLAN?

GOALS
Our goals are simple and clear – In order to accomplish our primary goal of replenishing the local water ways with our native Brook trout, we must focus on the aquatic habitats in our area. We hope to release our young trout into the best possible habitat – and this means monitoring the four major needs of a trout – food, water, shelter, and space. Educating the community is an equally important part of our plan.


Immediate:
· Raise a clutch of local Brook Trout eggs for release into a local waterway we have helped to restore.
· Understand connections between trout, healthy watershed, eco-systems and people
· Recognize trout as an important indicator species
· Cultivate an appreciation of trout and the need for coldwater conservation!!
Long Term:
Foster environmental stewardship and community involvement
Enable students to make informed decisions and create action plans about rescuing our aquatic resources

Step-By-Step

Research
Acquire and set up Trout in the Classroom Tank
Daily Tank Maintenance
Daily Water Quality Testing
Weekly Field Studies to determine need for restoration
Grow native plant species in classroom for future planting
Monthly Field trips for progressive restoration project focusing on the 4 elements trout need to be successful:
1. Food Source
2. Shelter
3. Clean Water
4. Adequate Space

Support needs of Trout in classroom including daily feeding and behavior monitoring
Educate Community about Coldwater Conservation and the Native Brook Trout
Prepare final release site
Release Trout in Spring
Continue to Monitor Stream Quality in the following years

Measuring Success/Quantifiable Results

Because this is an involved and ongoing project, the measurable impact of our efforts will not be fully recognizable until we are able to complete our plan. (Please see the Extra Credit graphs charts.) Along with the obvious impact of helping to increase the population of an important native fish – we will be permanently altering the eco-system with in our watershed. We know the importance of a clean and healthy watershed - restoring and cleaning up our local waterways impacts not only our immediate area but the entire Watershed. Understanding the connection between people, wildlife and water is more important than ever because we now know we have the power to make a measurable change in the world. Sharing this realization with our peers and community is empowering and allows us to continue in our journey of making a difference.


PART 3: YOUR PLAN IN ACTION: HOW DID YOU IMPLEMENT YOUR IDEAS?

On November 4, 2008 over 300 eggs of Pennsylvania Brook Trout arrived at our classroom. We are looking forward to a spring release date in a very clean section of Darby Creek which we have helped to restore. We are working with the community under the direction of Kevin Fryberger, Brandywine Conservancy Preserve Manager at Waterloo Mills, and we plan to release the trout in the spring in an area that we will be continuing to restore and plant with native plants. We have been diligent in our daily monitoring of the health of our trout and tank systems. We have been conducting weekly stream surveys and graphing the results of our restoration. As our trout grow and flourish we have been focusing our efforts on spreading awareness of the need for Watershed restoration. We have been holding open house for parents and community leaders and hosting elementary school children here in our classroom. During these events we talk about our research, show field studies results, conduct lesson plans and songs on trout life cycles and what role they play in the eco-system. We have distributed press releases under the direction of Katherine Mary and conducted power point presentations created by our Goalies. The blog has been a crucial part in generating interest in our projects.



PART 4: EVALUATE YOUR PLAN: WHAT ARE THE RESULTS?

We feel successful because of the tremendous effort we collectively have put forth. We have worked together to overcome challenges and our trout survival rate is significantly higher then the average. Some of the challenges we faced were learning about how to take the chemical tests, setting up the tank, if there was an unusual result in the chemical tests to find the problem and fix it, and finding a stream suitable to release the trout in. The positive outcomes are that we have raised awareness in the community, educated a 2nd grade class, parents, and community leaders at open house forums. We have paved the way for a brighter future for the watershed curriculum, for 2nd graders to get involved, and for community leaders to take action. We learned to take responsibility for aquatic ecosystems, water testing (chemistry), animal care (zoology), Brook Trout life cycles, and patience waiting for them to grow, to appreciate the need for replenishing native species, and how to carry out an environmental plan.
We continue to learn so much from this project. We have discovered within ourselves patience, responsibility, cooperation, understanding, and a new found faith in the future of our natural world. We have found ways in which we can truly make a difference. We want to thank our resident Marine Biologist Mrs. Agner, our tireless dedicated teachers Mrs. Ackerman, Mr. Savitch, and Trout Unlimited, our fabulous sponsor.

We love them all....


Some of our little friends aren't quite developing correctly. Hopefully they'll catch up soon!
SBTTSHYAC:
Connor has founded SBTTSHYAC (special Brook Trout that still have yolksacs affection commity). He makes sure that they are okay and no one treats them wrongly.

Trout exposed to light




Behavior: Some of the fish swim up a few inches and then slowly drift back down. But a little less than half of them have not exited the net. A few still have their yolk sacks. They are swimming like real fish now and moving around the rocky bottom!




Today we flipped the tank covering over for a little bit to get them used to more and more light.

Temperature- 49.2
pH- 7.4-7.2
Ammonia- .25 ppm
Nitrate- 3.0 ppm
Nitrite- 0 ppm

Trout Starting To Feed





Wednesday December 10 2008
12/10/08




Today we satrted to feed them and they are starting to get used to the light. We made a new FRY FEEDING chart to help us monitor their growth and behavior

About 25 trout have swam over the net and more are swiming over every minute! This means they are ready to begin foraging for food.



We'll start feeding them the size 0 food 1.5grams per day (broken up into 3-5 feedings)


2 trout have died - on average about 1-2 a day (still a much higher survival rate than they would have in the wild)

Today's test results:

Tempature- 50.1

pH- 7.2-7.4 (just right!)
Ammonia- .10 ppm (lower than 2 weeks ago)
Nitrate- 1 ppm
Nitrite- 0 ppm
Mitchell feeding .3 grams to start:

WATER IS THE DRIVER OF NATURE



As part of our ongoing ACTION PLAN we created - we participate in field studies to help determine the water quality of the stream around us. We will need to determine a healthy stream with specific qualities as a home for our trout when they are released in to the wild.




Today 8 of us traveled to a creek in WaterLoo Mills - a site we hope to help become the perfect new home for our Fingerlings to be.




We braved the chilly water and winds to determine the "HABI-TROUT" of this local waterway.


Once we determine the condition of these streams we will choose methods of improving the strea for the trout.

FOR Immediate Release

Radnor Students Take Positive Action
to Improve the Environment
Effort Provides Chance to Win Part of $1 Million in Grants and Scholarships

RADNOR, Pa, December 9, 2008 – A team of 10 students at Radnor Middle School have entered the second annual Lexus Eco Challenge, a national contest that encourages middle and high school students to develop and implement environmental programs that positively impact their communities.
The Lexus Eco Challenge, created by Lexus, the luxury automaker, and Scholastic, the global children’s publishing, education and media company, was designed to educate young people about the environment and to inspire them to create a better world. The students at Radnor Middle School have accepted the challenge by taking a stand and proving that a small group can bring about big changes. After carefully studying the local environment, the students have developed an Action Plan they feel will benefit their local community.
Our group has planned to restore the Pennsylvania native fish, the Brook Trout to our local streams. Since our 7th grade integrated learning program, Watershed, monitors water quality and is involved in many community action restoration projects we thought this would fit in perfectly with our studies. We have received 350 trout eggs from PA Fish and Wildlife to raise and release in habitat that we have restored in our own Darby Creek watershed. We are looking forward to a spring release date.
The community is invited to support the team’s Action Plan by donating gallons of natural spring water to help maintain a healthy habitat for our trout. Any stream clean up activities will be announced in the future.
Lexus and Scholastic will choose 16 winning teams nationwide. Each team will receive a total of $10,000 in grants and scholarships. All winning teams from this challenge and two other initial challenges will be invited to participate in the Final Challenge for a chance to win a grand prize of $50,000 in grants and scholarships.

WHAT'S THE ENVIRONMENTAL ISSUE?




Trout in the Classroom is a program designed for students to raise trout from eggs to fingerlings. Once at their fingerling stage we will release them into local streams. Why are we raising trout? We are raising trout to make us more aware about the connections between trout and healthy watersheds. Also, raising trout helps increase our declining brook trout population. Since the brook trout is our state fish we find it important to keep the population at the right increment. So how can we help the population of brook trout? Well, most brook trout die because of their predators, when they are young, but if we raise them while they are young, they have a greater chance of survival. By participating in Trout in the Classroom, we are helping save our watershed.
