We have hiked a good portion of Griff Creek up to this point. While the upper reaches held little riffles aerating the cool creek the lower section was a case study on urban runoff. Thankfully, all of the preschoolers agreed that we should release our fish directly into the lake (especially as this was the approved release site…;) ). It has bee amazing watching the kids grasp the idea of a watershed and see first hand the impact we have on water quality.
Upper Griff looked pretty good, cool and babbling.
Just above town wasn’t too bad either. Good flow but not too fast.
Uh oh. Three fast flowing culverts and some urban runoff. Not looking so hot. Going to have to release at the lake!
I have started to change 1/3 of my tank water 2-3 times per week. What is everyone else doing with their water? This picture illustrates my success with the cycle, however in years past at this same point, I start to lose fish rapidly, and I think it has to do with the chemistry of my tank water. Please chime in on ways to keep my water and fish happy.
Thanks for this great blog spot.
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.”
I’m just wondering if anyone else used the goldfish to create natural bacteria in their tanks?
This is the most updated list of approved release sites from the California Department of Fish and Wildlife…take a look!
“Holey moley! They are wriggling all over!” The excitement is palpable as our little preschool scientists observe the changes in our trout eggs. We often have visitors from other classes in the school pop in to confirm rumors of head and tail formation and super wiggly alevin. Next our goal is to find a quality location for the release of the trout once they rise in the tank as fry. As an exploration of the watershed in our backyard, we have been hiking sections of Griff Creek with the goal of making it from the headwaters all the way to Tahoe. During our exploration we are talking about what elements are critical for good trout habitat and ultimately deciding on an ideal release location.
