Up-Close Alevin Video

Great video from Mrs. McCheyne's South Seneca 5th grade classroom.  This is what our brown trout alevins look like, up close.  Roughly 2.2 cm in length.

Trout Feeding Advice From the Experts!


An Oldie, but a favorite!
Our Brown Trout alevins are not quite as big as seen in this video, but it won't be long.  They're finishing off their yolk sacks and we have reports of strong swimmers at most schools, now - right on schedule.  Mariah reports a successful first feeding by Groton's 6th graders!

Alevins are here!

Brook trout eggs have been delivered to Lansing, Dryden, Northeast and Caroline elementary schools, and should be hatching this week.

Meanwhile, our brown trout alevins are hatched and growing nicely at other schools.

Trout Releases Going Full Steam!

Good times releasing trout this week with Belle Sherman 5th grade, Enfield 4th and Union Springs 6th. “I think that we should keep on having trout because it is fun and very exciting to watch the fish grow up. 'Jaws' is 14 cm long now. He is the biggest trout that Mr. O has ever had in his class.” -Ethan Z. AJ Smith Elementary

More Results from Dryden Elementary, Groton Middle School, and Newfield Middle School!

For one of the classes at Groton we did a little side experiment and compared the amount of daphnia eaten by smaller trout compared to the larger trout and the preliminary results did indicate that the smaller trout ate more.

First Live Food Experiment!

Classes are now experimenting to see if their young trout- 2 or 3 centimeters in length now- will eat live food, like they would need to do in the wild. 

Our class visits start with an introduction to our test organism, a small crustacean called Daphnia.  Above, instructor Maria Mahaney leads an observation process designed to access students' stored knowledge and combine it with direct observation to form hypothesis about what these organisms are like.

Student research teams each prepare one trout (in 500 ml jar) and get 10 daphnia (test tube) to feed their trout.  Discussion and hypothesis-building happens before the actual experiment.

Finally, our experiment happens.  It only take five minutes of intense observation, teamwork and careful recording of data.  Results of this test often raise more questions than they answer, but that's just fine.  Below are some results for several schools- each chart represents the combined results of 6-10 student teams.
