Trout Report 1
Hi, we are a few 8th grade members of the I.S.
318 Trout In the Classroom Program, Sarah, Katherine, and Erika.
Every morning we go to the Ecology Center, room 222, to observe
and to take care of the trout.
The reason we are writing this notice is to announce that the trout eggs have hatched as of today, October 21, 1999. It has been ten days since their arrival. With the care of our trout members, some of the "Alevins" have finally emerged.
We discovered the trout hatching 8:30 A.M. in the morning of October 21, 1999. We first discovered little worm-like things coming out of the eggs. But they were merely the trout hatching from the eggs. At the beginning we had about 330 eggs but the numbers of the eggs gradually decreased to 223 as we removed dead eggs.
In the morning of October 21, 1999, we counted the trout that hatched. We counted nine eggs that hatched out of the 223 eggs. Then in the afternoon, when we counted the hatched eggs again, we discovered that more of the eggs have hatched during the period of time between 9:00 a.m. to 11:30. There were about 18-19 that hatched by lunch time. Then at the end of the day, even more eggs came out. We have had the trout-cam on so students can watch the process. This year we were able to record the eggs as they opened.
When the trout came out, their looks are very deceiving. A orange colored pouch (yolk sac) was attached to them. The trout didn't move much when they came out of the eggs. Sometimes they twitch a bit to free themselves from the egg coat. Some came out head first and some came out tail first. But the most important thing was that they came out of the eggs. The temperature in our Hatchery averages 50 F/ 9 C.
More news to come soon.
