Went to check out the vibert boxes. Word was, the eggs had hatched and they need to pull out the boxes. At the first rearing box, I was amazed to see the incredible amount of alvens. There has to be 80,000 plus alvens just in this one box. I would guess the success rate for the hatch was around 90%.
The second rearing box didn't fair as well as the first box. The egg rate survival was around 45%. The biologist thinks the eggs were exposed to the direct sunlight before they were put into the rearing box. But I would say all total, there are over 100,000 alvens that will soon turn into catchable size trout - if they survive that long. Hey man, there were predators waiting at the overflow tubes, called sucker fish. I also have some underwater on surface footage of them swimming around. I would think a 5% survival rate would be a good number. Now once these fingerlings are released, there will be one more shipment of eggs coming in March.
I'm putting together a documentary video on this Kings River project. I would like to have it completed in a couple weeks. Or at least a 15 minute version of it.
Most of the footage came from the Gopro 1080HD camera.
