4th graders test the pH

Greetings from Miss Coffey's class! This is our first year with the Trout in the Classroom program and we're trying desperately to keep our little guys alive! Unfortunately, we're having trouble keeping the pH level down and so far we've lost 11 trout. Here is Silas, Allyssa, and Tommy learning how to test the pH level.

Anticipation

4th graders at Caroline Elementary are so excited to get our trout Monday!!! Our tank is ready...

A NEW YEAR IS UNDERWAY!

The 2009-2010 schoolyear is well underway, and we are happy to announce that NINE area schools will be participating in Trout In The Classroom this year! We are setting up our aquariums, and all schools will be receiving Brown Trout eggs (or alevins) on Monday, November 2!

Welcome to our 2009 schools:

Cayuga Heights School 2nd Grade

Enfield Elementary 3rd Grade

South Hill, Belle Sherman and Caroline 4th Grades

Northeast 5th Grade

Newfield and Groton 7th Grades

Lansing 10th Grade Biology Students

Stay Tuned for updates!

Yesterday, 115 students from Boynton Middle School in Ithaca released 64 brown trout fry to Fall Creek, in Plumbers Pool, just below Ithaca Falls. The students raised their fry from eggs over the course of 6 months, had fun, and learned a great deal along the way!

Prior to releasing the trout, we checked conditions of the creek. The students found it to have a pH of 7.6, which is slightly basic and correlates well with conditions in the aquarium where the trout were raised. Additionally the water temperature in the pool was still in the mid-fifties, although temperatures in the shallower water were about 62 degrees F. Its getting warm for most trout and salmon, in Fall Creek, but the browns will be OK. A quick check of insect life in the stream reveals quite a few stonefly larvae, which are indicators of good quality habitat and provide excellent food for brown trout.

The students concluded that Fall Creek will provide a good habitat, and completed the release. Now the trout will need to fend for themselves in a new environment. The habitat may be fine, but they'll need to content with the fishing Great Blue Heron we observed, bass, and other predators. To see more pictures, click here!

Congratulations to Mrs. Morton's 6th graders, and thanks to the Leon Chandler Trout Unlimited members, and all who helped! Check out our article in the Ithaca Journal!

Lansing High School results of Cayuga Lake Measurments

Out on the floating laboratory on Cayuga Lake, we collected data on many aspects of the lake's environment including depth, water clarity, temperature, and types of organisms in the water. These were our results:

The measurements were taken in the middle of the lake, just North of Meyer's park. Specifically, the laboratory was stationed at 42° 32.125' North latitude, 76° 33.723' West longitude. On May 11th, conditions were calm and sunny; On May 12th, conditions were overcast and windy. Lake surface on both days was relatively calm with a few small waves and ripples.

The average air temperature recorded was 54.8 degrees, with a range between 46 and 64 degrees at different times in the day. Water pH and temperature samples were taken at varying depths, some as deep as 75 meters below the surface. Listed below is a range of temperatures and pH readings at various depths:

Depth(m) - Temperature(F) - pH

1 - 46 - 8

5 - 47 - 8

20 - 46 - 8.5

30 - 47 - 8

40 - 43 - 8

50 - 43 - 8

75 - 42 - *

* = no reading

Secchi disks, the devices used to read light penetration through the water, indicated an average visual depth of 4.78 meters, with reading ranging from 4.25 to 6 meters. These readings categorized Cayuga lake as Mesotrphic. Actual sunlight penetration depths are closer to twice the visual depth.

Plankton samples were also collected. Samples were taken from depths ranging fromhalf a meter to 20 meters, with an average sample depth of 9.3 meters. Most samples were collected at 8 meters. At 10 meters, samples collected contained lots of plankton and algae, coloring the water green. Samples at depths shallower than five or deeper than 10 were mostly clear, containing very little life. The most common types of phytoplankton found were Diatoms, small plankton that resemble snowflakes. The most common types of zooplankton were Calanoids, which look like very tiny fish with feelers.

Yesterday in Groton we released our trout into the Owasco Inlet across the street from the school. This stretch is a public fishing access so hopefully one day a fly fisherman can admire the brown trout's beauty the way we did for 5 months. Thank you Bill and Trout Unlimited for this experience.

CURRENT Events....

New York State is considering a ban on phosphorus in dishwashing and other detergents, do to the impact of this mineral on streams and lakes. For more info, check this out.

The Town of Ithaca is considering new rules to limit construction and development along streams. Is this a good idea? What do you think?? (Find more info at http://www.town.ithaca.ny.us/setback.htm)

Feeding Time Update

All of our trout are doing wonderfully well.  I raised the temp by 2 degrees to encourage more growth.  We also participated in the live feeding experiment of zooplankton the week before break.  I have some great video clips that I would like to upload if anyone knows how to import these.  I have made many attempts to update my drivers, etc, but the video file cannot be read by a PC because of the .VRO string attached to the file.  The experiment was an exciting opportunity for students to observe some trout behavior.

Most students were accurately describe the features of the trout.  They either listed the parts (head, tail, etc), colorizations and red gills during eating time.

Students felt that the trout were mostly scared or nervous and stayed pretty still.  Some groups had  active trout and were observed swimming around fast in circles.

Hypothesis:  Most groups felt that their trout would quickly eat the zooplankton once they recognized it.  Two groups had the hypothesis that the trout would not know what the zooplankton was so they would not eat it.

Results:  All the groups reported that they observed the trout actively feeding, chasing the zooplankton and swimming fast.  Although some groups over counted (by a lot) at times the number of zooplankton that was really consumed by the fish and as a result this threw off some numbers.  Some groups numbers were too high because they miscounted an aggressive action by the fish as eating.  However, this was a fantastic test for the students to participate in and they are still talking about it today.

Busy Week!

Hi everyone, and welcome back from break!
The week before break was a busy one- we conducted feeding experiments at all six schools, and I think we got some very interesting results, which I will try to post in the next few days. Many trout seemed to respond to our zooplankton and begin feeding; others did not. Does anyone have specific results to share?

I would also like to thank Colleen Kearns, from Cornell's Department of Evolutionary Biology & Ecology, and Michael Lenetsky from Trout Unlimited for their tremendous help. We had a great time, and I know they are awaiting any questions form the classes!

Great Week

Our third grade class would like to send a very special "THANKS" to Ms. Rubin and her class at CHE who graciously donated  trout to our classroom.  Our class was touched by this and wanted to let you know how much we appreciate it.  Speedy and others are doing great and Mr. Brooks will be going over there everyday over break to check in on them.   

Bill and our mentor, Rich, came out to Enfield on Wednesday to perform an experiment with Daphnia and trout feeding behavior.  This was a wonderful time full of great questions and interactions between students, trout and our mentors.  We've put together a video and we are hopeful it will be uploaded soon.   

Thanks,

Mr. Brooks' Class
