Its Fishy Friday - wanted to continue to keep people updated on the success of our Woundfin propagation up at the Utah Aquatic Animal Health and Research Center in Logan. Back in April Woundfin started spawning. Biologists initially spawned about 30 fish at a time. Woundfin are batch spawners, meaning that females release a group of eggs for fertilization then have to wait for more to mature before releasing again. This may take a couple of weeks and is dependent on environmental conditions. Here is a short video of some of the early spawned woundfin.

We had great participation in the fundraiser for the Andrew Barnum Museum of Natural History on Saturday. We had quite a few tables where people could learn about different entities. Thanks to all of them for showing up as well as all of the groups and individuals who donated prizes for the ducky race and the silent auction. Had a few photos of the race.
So now that some Woundfin reproduction is out of the way, lets get on to the outcomes. The spawning from the first 32 adults resulted in about 250 larvae, the next set of 32 produced about the same. Here are some videos of those two sets of larvae. First the older group then the second group where you can see them eating as Utah product, Brine Shrimp from the GSL.
To follow up from the last Woundfin post, ultimately about 2,500 eggs were laid amongst 32 adults (s*x ratio undetermined). Eggs that developed to the eyeing stage were about 30%. Currently there are about 200 larvae buzzing about. New trials to begin next week. Video below shows a couple of the larvae.
