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.
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!!!
Hi all, we have three classrooms with trout. In two of them, there are only a handful of living trout left. In the last classroom, we have a good twenty or so. My theory is that the other two tanks has gravel as well as larger rocks and the third tank has gravel and small golf-ball or smaller sized rocks. When searching for living alevin, I found that many had gotten stuck under the rocks and died. On the TIC website, most people have a hatching basket that the eggs and alevin are in until they can swim out on their own. I’m theorizing that this may be the problem we are having. So, I have since removed all rocks except the gravel and will see what results we have. Just a suggestion for others. Keep your finger(lings) crossed!!!!
