We had our first egg hatch on Thursday October 19th and a total of 6 as of today. Our water temperature has been a consistent 51 degrees. One of our eggs definitely contains two heads. That should be fun to monitor. Since the arrival (10/12), we have had 137 dead or infertile eggs. More to come…
First hatchlings!

It seems that a few schools are seeing some early hatchlings. While conventional wisdom dictates that brook trout need about 450 ATUs to hatch, that figure can and does vary. If the school who received their eggs on the 12th had kept their water temps at 52 degrees (F), the hatch date should be on or about Halloween, the 31st. I’m curious as to why we’re seeing several early hatchers and will inquire at the Pequest Hatchery. Having a fairly large number of eggs that are either not fertilized or are dead is common although this year’s incident rate seems slightly higher than normal. Again, I will inquire with Fish & Wildlife fisheries biologists to get more information about these happenings.
