We now have little alevin swimming around! It's hard to see, but those little grey lines are the fish, and the orange part is their yolk sack. The yolk sack is their food source for the time being. As you can see, they are still in their egg basket, but as soon as they absorb their yolk sack they will swim out of the basket and we will begin feeding them their regular food. At this time, they are tiny! Each little head is probably the size of the head of the pencil. Come and see our new pets!
Wow! That is so cool! This is such a great experience to provide for your students. About how long will it be before the yolk sacks are gone? Will there be enough room in the tank for all of those fish when they have grown?

Their yolk sacks will be a part of them for about a week to ten days, depending on when they hatched. Since we were on Thanksgiving Break, I'm not sure if they hatched this morning or Tuesday evening, so it's a guessing game at this point.
ReplyDeleteThey will grow to about 3-4 inches before we let them go. Last year the classes received 300 eggs and it was too crowded, so this year they gave us only 200. So far we've had about 7 die, so that leaves us with about 193. They'll be so tiny that I think they'll do fine. Some other classes across Kentucky started way earlier and I've heard that their fish will be 9-10 inches long when they're released!
Is that what those belly-like things that are attached to them are called? Yolk sacks? I wasn't sure if it was something they fed off of or their bellies that they would grow into...
ReplyDeleteI am so happy that they have hatched!!!Do you know how long we will keep them??I am very excited to see them grow up!

ReplyDeleteThey are so small and the yolk sacks are huge on them.
ReplyDelete@Anonymous - their yolk sacs are the eggs that they were in when they were in their egg stage. However, unlike a chick that breaks out of the egg and automatically begins eating food, fish will absorb their yolk sacs into their bellies for 1-3 weeks and won't need to eat food until then.
ReplyDelete@H8 - we will keep them until the Spring when we will release them into their natural watershed. It will be so much fun!
@H4 - they hatched because it was their time to do so. They could only stay in the egg stage for so long before they became too big for their eggs to contain them. They were born in a hatchery in south central Kentucky called Wolf Creek National Fish Hatchery. You can visit their website at feed://www.facebook.com/feeds/page.php?format=atom10&id=123211137706787. There are lots of cool videos and pictures on their website that show the fish. You'd love it!
@H10 - I'm so glad that you like and are learning from the trout! They will be between 3-4 inches when we release them. It doesn't seem very big, but it's huge compared to the tiny eggs they came from!
@H15 - I think it's really cool that other classes can see our trout, too. The trout are "floating" because that's them practicing to swim. At this time they can't swim because their yolk sacs are too heavy and they're not strong enough. It's like a baby that's trying to learn how to walk or crawl.
@S11 - Yes, their yolk sacs are huge right now, but that means that there's a lot of food to keep them full for a while. When we have to start feeding them it will get pretty stressful. I hope that you're ready and willing to apply for our Trout Team after Christmas Break!

ReplyDeleteIm here with my Hanners Hero and we saw your blog. I am so happy you got a class pet this year! I hope they live a long life!
Barnard's Class #12 - We are so glad that you get to come and be a Hero to one of our little guys. You are helping more than you know! I'm so glad that you got to come and see our fish. We plan on releasing them in the Spring. I think it's such a cool project. Stop by often and see our fish grow!
