     10/27/14   Biologists from Cold Spring Fish Hatchery visited 5-L to perform a trout egg stripping and fertilization demonstration.  Students witnessed one of the most fascinating aspects of aquaculture with a centuries-old technique of fish breeding; egg taking and fertilization. After, the demonstration students and biologists participated in a discussion of trout development, and a comparison of hatchery breeding and spawning in the wild.  The eggs were quickly placed in our classroom habitat where we will observe the life cycle of these fascinating fish.

    Farewell, Trout!
             May 18th was quite a day for the students and trout of 5-L. After 10 months of raising our little fish from eggs to fingerlings, we released approximately 70 healthy trout into the cool clean stream waters at Ward Pound Ridge Reservation. It was an outing filled with fishing, hiking, journaling, painting, and BBQ! The day was certainly one to remember.
