We popped newly hatched alevins onto out classroom digital projector, at Northeast Elementary.
Brook trout eggs are about 4mm in diameter, while newly hatched alevins are about 9mm in length. How does that alevin fit into that egg??
Do The Math: The internal (inside the eggshell) diameter of the eggs is probably about 3mm. Calculate the circumference of that internal space by multiplying the 3mm diameter by Pi (3.14). You get just over 9mm!

Students viewed the eyed eggs up close before we placed them in their new aquarium homes. We are always amazed by the size and potential of these tiny eggs. The kids will make regular observations of the developing embryos and newly hatched brook trout, which tend to run 3-4 weeks behind out brown trout eggs. Thanks to Patti Jennings and her great 3rd grade enrichment students at Lansing Elementary for these pix!
