Now that many of your trout are swimming up, it may be time to feed them. I received the following advice from the fisheries biologist at the Lahonton Nation Fish Hatchery on when and how much to feed your trout. Hope it helps…..
“You don’t need to feed the trout until the yolk sac is gone, and then it’s just a small pinch every third day. Have the teachers watch the first few times they feed because they want to make sure that most if not all of the food is consumed each time. The biggest worry is overfeeding that will cause all kinds of problems with the tank. So just have the teachers do a very small amount when they feed and if the food is all eaten then they can add a little more. I wouldn’t expect that the fry will need lots of food right now. As they grow they can add some food.”
This is the most updated list of approved release sites from the California Department of Fish and Wildlife…take a look!
According to the fisheries biologist from the Lahonton National Fish Hatchery, you should start to observe your fish swimming up between May 29th-May 31st. Once they swim up, they can be released to the wild, or you can begin feeding them and let them grow in your tank a while longer. (Keep in mind that once you start feeding them, they also start producing waste…..the water chemistry can be tricky at this point.)
So, what are your plans for release? We are excited to hear how your class will be celebrating the Lahonton Cutthroat Trout send off!!!
Here is a great, online resource for your students to learn more about the Lahonton Cutthroat Trout, and other trout and salmon species.
