Release day is a fun and special event with your class. Now is a good time to begin planning your release day especially if you require buses, extra funding, or are looking to have a local naturalist present at your event.The information below should help you plan.
While your permit allows you to keep the fish up to 8 weeks from the day of egg delivery, we recommend releasing fish soon after they “button up” (absorb the yolk sac). This generally occurs within 4-6 weeks of hatch.
The risk of mortality increases the longer you keep the fish in your tank. While only 1-2% of classes in the Bay Area experience “total tank failure” each year, it is really unfun if it is your class. We cannot always figure out what went wrong in each case, but the two most common factors are that the fish are being feed and they have been held longer than 6 weeks.
If you are hatching rainbow trout (which most of you are):
Assume you will receive your eggs the first few days of March, 2017. That means they should be in the lake NO LATER than April 28 2017. I would recommend you look at a release date of much earlier – 5 to 6 weeks after delivery.
If you are hatching Steelhead trout, you have three options for egg pick up:
- February 8, 2017 (final date fry must be released – April 5, 2017)
- March 15, 2017 (final date fry must be released – May 10, 2017)
April 5, 2017 (final date fry must be released – May 31, 2017)
Again, we recommend releasing at least 2 weeks prior to final release date.
We hope this helps you plan your release day activities.
