I recently moved my brine hatchery from the bathroom counter into the cabinet, to hid the noise and the light from view. (My house is already so much like a fish store it\’s rather pathetic! lol!) I started using a lower wattage light, since in the cabinet the higher light was making the bottles too warm, and I peeled the labels off the bottles (regular water bottle types) and suddenly my hatching went from 24 hour cycles to 12 hours! This is proving to be a problem for me as I was feeding once in the morning and once at night and adding the eggs at feeding time. Now…. I have TWO bottles ready at once, and one hatched hours ago, and the other more recently. This has been happening for a few days and I\’ve been trying to figure out how I can do optimum feedings, especially if I am not here all day to watch the hatcheries.
I just can\’t believe the huge difference just rearranging the hatchery made. (I think it as the extra light they got from peeling the labels…. )January 5, 2007 at 11:49 pm #3233Pete GiwojnaGuest
Yes, some of the factors that are known to shorten or speed up the hatching time for Artemia cysts (i.e., brine shrimp eggs) are warm temperature, adequate light levels, and decapsulating the eggs before hatching. The eggs need to be exposed to light in order to hatch, so peeling the labels off your hatching jars certainly could have increased the amount of illumination they received and hastened the hatching process. The warmer temperatures inside the cabinets probably also played a role in the faster hatches. By adjusting those two variables — the amount of light the hatching jars receive and the water temperature — you should be able to manipulate the hatching times through a process of trial and error so that it works well for your feeding schedule.
Best of luck getting your brine shrimp hatches better synchronized with your feeding regimen, Carrie!
